 Boundary scan for simplified board testing.
Memory:
 512 kB on-chip flash program memory with In-System Programming (ISP) and
In-Application Programming (IAP) capabilities. The combination of an enhanced
flash memory accelerator and location of the flash memory on the CPU local
code/data bus provides high code performance from flash.
 Up to 96 kB on-chip SRAM includes:
64 kB of main SRAM on the CPU with local code/data bus for high-performance
CPU access.
Two 16 kB peripheral SRAM blocks with separate access paths for higher
throughput. These SRAM blocks may be used for DMA memory as well as for
general purpose instruction and data storage.

Transistors (TFT) displays.
 Dedicated DMA controller.
 Selectable display resolution (up to 1024  768 pixels).
 Supports up to 24-bit true-color mode.
External Memory Controller (EMC) provides support for asynchronous static memory
devices such as RAM, ROM and flash, as well as dynamic memories such as single
data rate SDRAM.
Eight channel General Purpose DMA controller (GPDMA) on the AHB multilayer
matrix that can be used with the SSP, I2S, UART, CRC engine, Analog-to-Digital and
Digital-to-Analog converter peripherals, timer match signals, GPIO, and for
memory-to-memory transfers.

32-bit ARM Cortex-M4 microcontroller
 Five UARTs with fractional baud rate generation, internal FIFO, DMA support, and
RS-485/EIA-485 support. One UART (UART1) has full modem control I/O, and one
UART (USART4) supports IrDA, synchronous mode, and a smart card mode
conforming to ISO7816-3.
 Three SSP controllers with FIFO and multi-protocol capabilities. The SSP
interfaces can be used with the GPDMA controller.
 Three enhanced I2C-bus interfaces, one with a true open-drain output supporting
the full I2C-bus specification and Fast-mode Plus with data rates of 1 Mbit/s, two
with standard port pins. Enhancements include multiple address recognition and
monitor mode.
 I2S (Inter-IC Sound) interface for digital audio input or output. It can be used with
the GPDMA.
 CAN controller with two channels.
 Digital peripherals:
 SD/MMC memory card interface.
 Up to 165 General Purpose I/O (GPIO) pins depending on the packaging, with
configurable pull-up/down resistors, open-drain mode, and repeater mode. All
GPIOs are located on an AHB bus for fast access and support Cortex-M4
bit-banding. GPIOs can be accessed by the General Purpose DMA Controller. Any
pin of ports 0 and 2 can be used to generate an interrupt.
 Two external interrupt inputs configurable as edge/level sensitive. All pins on port 0
and port 2 can be used as edge sensitive interrupt sources.
 Four general purpose timers/counters, with a total of eight capture inputs and ten
compare outputs. Each timer block has an external count input. Specific timer
events can be selected to generate DMA requests.
 Quadrature encoder interface that can monitor one external quadrature encoder.
 Two standard PWM/timer blocks with external count input option.
 One motor control PWM with support for three-phase motor control.
 Real-Time Clock (RTC) with a separate power domain. The RTC is clocked by a
dedicated RTC oscillator. The RTC block includes 20 bytes of battery-powered
backup registers, allowing system status to be stored when the rest of the chip is
powered off. Battery power can be supplied from a standard 3 V lithium button cell.
The RTC will continue working when the battery voltage drops to as low as 2.1 V.
An RTC interrupt can wake up the CPU from any reduced power mode.
 Event Recorder that can capture the clock value when an event occurs on any of
three inputs. The event identification and the time it occurred are stored in
registers. The Event Recorder is located in the RTC power domain and can
therefore operate as long as there is RTC power.
 Windowed Watchdog Timer (WWDT). Windowed operation, dedicated internal
oscillator, watchdog warning interrupt, and safety features.
 CRC Engine block can calculate a CRC on supplied data using one of three
standard polynomials. The CRC engine can be used in conjunction with the DMA
controller to generate a CRC without CPU involvement in the data transfer.
 Analog peripherals:
 12-bit Analog-to-Digital Converter (ADC) with input multiplexing among eight pins,
conversion rates up to 400 kHz, and multiple result registers. The 12-bit ADC can
be used with the GPDMA controller.

6.2 Pin description
I/O pins on the LPC408x/7x are 5 V tolerant and have input hysteresis unless otherwise
indicated in the table below. Crystal pins, power pins, and reference voltage pins are not
5 V tolerant. In addition, when pins are selected to be ADC inputs, they are no longer 5 V
tolerant and the input voltage must be limited to the voltage at the ADC positive reference
pin (VREFP).
All port pins Pn[m] are multiplexed, and the multiplexed functions appear in Table 3 in the
order defined by the FUNC bits of the corresponding IOCON register up to the highest
used function number. Each port pin can support up to eight multiplexed functions.
IOCON register FUNC values which are reserved are noted as “R” in the pin configuration
table.

7. Functional description
7.1 Architectural overview
The ARM Cortex-M4 includes three AHB-Lite buses: the system bus, the I-code bus, and
the D-code bus. The I-code and D-code core buses are faster than the system bus and
are used similarly to Tightly Coupled Memory (TCM) interfaces: one bus dedicated for
instruction fetch (I-code) and one bus for data access (D-code). The use of two core
buses allows for simultaneous operations if concurrent operations target different devices.
The LPC408x/7x use a multi-layer AHB matrix to connect the ARM Cortex-M4 buses and
other bus masters to peripherals in a flexible manner that optimizes performance by
allowing peripherals that are on different slaves ports of the matrix to be accessed
simultaneously by different bus masters.
7.2 ARM Cortex-M4 processor
The ARM Cortex-M4 processor is running at frequencies of up to 120 MHz. The processor
executes the Thumb-2 instruction set for optimal performance and code size, including
hardware division, single-cycle multiply, and bit-field manipulation. A Memory Protection
Unit (MPU) supporting eight regions is included.
7.3 ARM Cortex-M4 Floating Point Unit (FPU)
Remark: The FPU is available on parts LP4088/78/76.
The FPU supports single-precision floating-point computation functionality in compliance
with the ANSI/IEEE Standard 754-2008. The FPU provides add, subtract, multiply, divide,
multiply and accumulate, and square root operations. It also performs a variety of
conversions between fixed-point, floating-point, and integer data formats.
7.4 On-chip flash program memory
The LPC408x/7x contain up to 512 kB of on-chip flash program memory. A new two-port
flash accelerator maximizes performance for use with the two fast AHB-Lite buses.

7.5 EEPROM
The LPC408x/7x contains up to 4032 byte of on-chip byte-erasable and
byte-programmable EEPROM data memory.
7.6 On-chip SRAM
The LPC408x/7x contain a total of up to 96 kB on-chip SRAM data memory. This includes
64 kB main SRAM, accessible by the CPU and DMA controller on a higher-speed bus,
and up to two additional 16 kB peripheral SRAM blocks situated on a separate slave port
on the AHB multilayer matrix.
This architecture allows CPU and DMA accesses to be spread over three separate RAMs
that can be accessed simultaneously.
7.7 Memory Protection Unit (MPU)
The LPC408x/7x have a Memory Protection Unit (MPU) which can be used to improve the
reliability of an embedded system by protecting critical data within the user application.
The MPU allows separating processing tasks by disallowing access to each other's data,
disabling access to memory regions, allowing memory regions to be defined as read-only
and detecting unexpected memory accesses that could potentially break the system.
The MPU separates the memory into distinct regions and implements protection by
preventing disallowed accesses. The MPU supports up to eight regions each of which can
be divided into eight subregions. Accesses to memory locations that are not defined in the
MPU regions, or not permitted by the region setting, will cause the Memory Management
Fault exception to take place.

7.10 Pin connect block
The pin connect block allows selected pins of the microcontroller to have more than one
function. Configuration registers control the multiplexers to allow connection between the
pin and the on-chip peripherals.
Peripherals should be connected to the appropriate pins prior to being activated and prior
to any related interrupts being enabled. Activity of any enabled peripheral function that is
not mapped to a related pin should be considered undefined.
Most pins can also be configured as open-drain outputs or to have a pull-up, pull-down, or
no resistor enabled.

during a given data transfer. The SSP supports full duplex transfers, with frames of 4 bits
to 16 bits of data flowing from the master to the slave and from the slave to the master. In
practice, often only one of these data flows carries meaningful data.

7.25 I2C-bus serial I/O controllers
The LPC408x/7x contain three I2C-bus controllers.
The I2C-bus is bidirectional for inter-IC control using only two wires: a Serial Clock Line
(SCL) and a Serial Data Line (SDA). Each device is recognized by a unique address and
can operate as either a receiver-only device (e.g., an LCD driver) or a transmitter with the
capability to both receive and send information (such as memory). Transmitters and/or
receivers can operate in either master or slave mode, depending on whether the chip has
to initiate a data transfer or is only addressed. The I2C is a multi-master bus and can be
controlled by more than one bus master connected to it.
7.25.1 Features
• All I2C-bus controllers can use standard GPIO pins with bit rates of up to 400 kbit/s

NXP Semiconductors
32-bit ARM Cortex-M4 microcontroller
The I2S-bus specification defines a 3-wire serial bus using one data line, one clock line,
and one word select signal. The basic I2S connection has one master, which is always the
master, and one slave. The I2S interface on the LPC408x/7x provides a separate transmit
and receive channel, each of which can operate as either a master or a slave.
7.26.1 Features
• The interface has separate input/output channels each of which can operate in master
or slave mode.
• Capable of handling 8-bit, 16-bit, and 32-bit word sizes.
• Mono and stereo audio data supported.
• The sampling frequency can range from 16 kHz to 48 kHz (16, 22.05, 32, 44.1,
48) kHz.

• Controls include reset, stop and mute options separately for I2S input and I2S output.
7.27 CAN controller and acceptance filters
The LPC408x/7x contain one CAN controller with two channels.
The Controller Area Network (CAN) is a serial communications protocol which efficiently
supports distributed real-time control with a very high level of security. Its domain of
application ranges from high-speed networks to low cost multiplex wiring.
The CAN block is intended to support multiple CAN buses simultaneously, allowing the
device to be used as a gateway, switch, or router between two of CAN buses in industrial
or automotive applications.
Each CAN controller has a register structure similar to the NXP SJA1000 and the PeliCAN
Library block, but the 8-bit registers of those devices have been combined in 32-bit words
to allow simultaneous access in the ARM environment. The main operational difference is
that the recognition of received Identifiers, known in CAN terminology as Acceptance
Filtering, has been removed from the CAN controllers and centralized in a global
Acceptance Filter.

• FullCAN messages can generate interrupts.
7.28 General purpose 32-bit timers/external event counters
The LPC408x/7x include four 32-bit timer/counters.
The timer/counter is designed to count cycles of the system derived clock or an
externally-supplied clock. It can optionally generate interrupts, generate timed DMA
requests, or perform other actions at specified timer values, based on four match
registers. Each timer/counter also includes two capture inputs to trap the timer value when
an input signal transitions, optionally generating an interrupt.
7.28.1 Features
• A 32-bit timer/counter with a programmable 32-bit prescaler.
• Counter or timer operation.
• Two 32-bit capture channels per timer, that can take a snapshot of the timer value
when an input signal transitions. A capture event may also generate an interrupt.
• Four 32-bit match registers that allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.
• Up to four external outputs corresponding to match registers, with the following
capabilities:
– Set LOW on match.
– Set HIGH on match.
– Toggle on match.
– Do nothing on match.
• Up to two match registers can be used to generate timed DMA requests.
7.29 Pulse Width Modulator (PWM)
The LPC408x/7x contain two standard PWMs.
The PWM is based on the standard Timer block and inherits all of its features, although
only the PWM function is pinned out on the LPC408x/7x. The Timer is designed to count
cycles of the system derived clock and optionally switch pins, generate interrupts or
perform other actions when specified timer values occur, based on seven match registers.
The PWM function is in addition to these features, and is based on match register events.
The ability to separately control rising and falling edge locations allows the PWM to be
used for more applications. For instance, multi-phase motor control typically requires
three non-overlapping PWM outputs with individual control of all three pulse widths and
positions.
Two match registers can be used to provide a single edge controlled PWM output. One
match register (PWMMR0) controls the PWM cycle rate, by resetting the count upon
match. The other match register controls the PWM edge position. Additional single edge

NXP Semiconductors
32-bit ARM Cortex-M4 microcontroller
controlled PWM outputs require only one match register each, since the repetition rate is
the same for all PWM outputs. Multiple single edge controlled PWM outputs will all have a
rising edge at the beginning of each PWM cycle, when an PWMMR0 match occurs.
Three match registers can be used to provide a PWM output with both edges controlled.
Again, the PWMMR0 match register controls the PWM cycle rate. The other match
registers control the two PWM edge positions. Additional double edge controlled PWM
outputs require only two match registers each, since the repetition rate is the same for all
PWM outputs.
With double edge controlled PWM outputs, specific match registers control the rising and
falling edge of the output. This allows both positive going PWM pulses (when the rising
edge occurs prior to the falling edge), and negative going PWM pulses (when the falling
edge occurs prior to the rising edge).
7.29.1 Features
• LPC408x/7x has two PWM blocks with Counter or Timer operation (may use the
peripheral clock or one of the capture inputs as the clock source).
• Seven match registers allow up to 6 single edge controlled or 3 double edge
controlled PWM outputs, or a mix of both types. The match registers also allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.
• Supports single edge controlled and/or double edge controlled PWM outputs. Single
edge controlled PWM outputs all go high at the beginning of each cycle unless the
output is a constant low. Double edge controlled PWM outputs can have either edge
occur at any position within a cycle. This allows for both positive going and negative
going pulses.
• Pulse period and width can be any number of timer counts. This allows complete
flexibility in the trade-off between resolution and repetition rate. All PWM outputs will
occur at the same repetition rate.
• Double edge controlled PWM outputs can be programmed to be either positive going
or negative going pulses.
• Match register updates are synchronized with pulse outputs to prevent generation of
erroneous pulses. Software must ‘release’ new match values before they can become
effective.
• May be used as a standard 32-bit timer/counter with a programmable 32-bit prescaler
if the PWM mode is not enabled.
7.30 Motor control PWM
The LPC408x/7x contain one motor control PWM.
The motor control PWM is a specialized PWM supporting 3-phase motors and other
combinations. Feedback inputs are provided to automatically sense rotor position and use
that information to ramp speed up or down. An abort input is also provided that causes the
PWM to immediately release all motor drive outputs. At the same time, the motor control
PWM is highly configurable for other generalized timing, counting, capture, and compare
applications.

7.31 Quadrature Encoder Interface (QEI)
Remark: The QEI is available on parts LPC4088/78/76.
A quadrature encoder, also known as a 2-channel incremental encoder, converts angular
displacement into two pulse signals. By monitoring both the number of pulses and the
relative phase of the two signals, the user can track the position, direction of rotation, and
velocity. In addition, a third channel, or index signal, can be used to reset the position
counter. The quadrature encoder interface decodes the digital pulses from a quadrature
encoder wheel to integrate position over time and determine direction of rotation. In
addition, the QEI can capture the velocity of the encoder wheel.

a dedicated SYSTICK exception at a 10 ms interval. In the LPC408x/7x, this timer can be
clocked from the internal AHB clock or from a device pin.

• The Watchdog Clock (WDCLK) source is a dedicated watchdog oscillator, which is
always running if the watchdog timer is enabled.
7.34 RTC and backup registers
The RTC is a set of counters for measuring time when system power is on, and optionally
when it is off. The RTC on the LPC408x/7x is designed to have extremely low power
consumption, i.e. less than 1 A. The RTC will typically run from the main chip power
supply conserving battery power while the rest of the device is powered up. When
operating from a battery, the RTC will continue working down to 2.1 V. Battery power can
be provided from a standard 3 V lithium button cell.
An ultra-low power 32 kHz oscillator will provide a 1 Hz clock to the time counting portion
of the RTC, moving most of the power consumption out of the time counting function.
The RTC includes a calibration mechanism to allow fine-tuning the count rate in a way
that will provide less than 1 second per day error when operated at a constant voltage and
temperature.
The RTC contains a small set of backup registers (20 bytes) for holding data while the
main part of the LPC408x/7x is powered off.
The RTC includes an alarm function that can wake up the LPC408x/7x from all reduced
power modes with a time resolution of 1 s.
7.34.1 Features

7.35 Event monitor/recorder
The event monitor/recorder allows recording of tampering events in sealed product
enclosures. Sensors report any attempt to open the enclosure, or to tamper with the
device in any other way. The event monitor/recorder stores records of such events when
the device is powered only by the backup battery.
7.35.1 Features
• Supports three digital event inputs in the VBAT power domain.
• An event is defined as a level change at the digital event inputs.
• For each event channel, two timestamps mark the first and the last occurrence of an
event. Each channel also has a dedicated counter tracking the total number of events.
Timestamp values are taken from the RTC.

7.36 Clocking and power control
7.36.1 Crystal oscillators
The LPC408x/7x include four independent oscillators. These are the main oscillator, the
IRC oscillator, the watchdog oscillator, and the RTC oscillator.
Following reset, the LPC408x/7x will operate from the Internal RC oscillator until switched
by software. This allows systems to operate without any external crystal and the boot
loader code to operate at a known frequency.
See Figure 10 for an overview of the LPC408x/7x clock generation.

7.36.1.1
Internal RC oscillator
The IRC may be used as the clock that drives the PLL and subsequently the CPU. The
nominal IRC frequency is 12 MHz. The IRC is trimmed to 1 % accuracy over the entire
voltage and temperature range.
Upon power-up or any chip reset, the LPC408x/7x use the IRC as the clock source.
Software may later switch to one of the other available clock sources.
7.36.1.2
Main oscillator
The main oscillator can be used as the clock source for the CPU, with or without using the
PLL. The main oscillator also provides the clock source for the alternate PLL1.
The main oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be
boosted to a higher frequency, up to the maximum CPU operating frequency, by the main
PLL. The clock selected as the PLL input is PLLCLKIN. The ARM processor clock
frequency is referred to as CCLK elsewhere in this document. The frequencies of
PLLCLKIN and CCLK are the same value unless the PLL is active and connected. The
clock frequency for each peripheral can be selected individually and is referred to as
PCLK. Refer to Section 7.36.2 for additional information.

7.36.1.3
RTC oscillator
The RTC oscillator provides a 1 Hz clock to the RTC and a 32 kHz clock output that can
be output on the CLKOUT pin in order to allow trimming the RTC oscillator without
interference from a probe.
7.36.1.4
Watchdog oscillator
The Watchdog Timer has a dedicated oscillator that provides a 500 kHz clock to the
Watchdog Timer that is always running if the Watchdog Timer is enabled. The Watchdog
oscillator clock can be output on the CLKOUT pin in order to allow observe its frequency.
In order to allow Watchdog Timer operation with minimum power consumption, which can
be important in reduced power modes, the Watchdog oscillator frequency is not tightly
controlled. The Watchdog oscillator frequency will vary over temperature and power
supply within a particular part, and may vary by processing across different parts. This
variation should be taken into account when determining Watchdog reload values.
Within a particular part, temperature and power supply variations can produce up to a
17 % frequency variation. Frequency variation between devices under the same
operating conditions can be up to 30 %.
7.36.2 Main PLL (PLL0) and Alternate PLL (PLL1)
PLL0 (also called the Main PLL) and PLL1 (also called the Alternate PLL) are functionally
identical but have somewhat different input possibilities and output connections. These
possibilities are shown in Figure 10. The Main PLL can receive its input from either the
IRC or the main oscillator and can potentially be used to provide the clocks to nearly
everything on the device. The Alternate PLL receives its input only from the main oscillator
and is intended to be used as an alternate source of clocking to the USB. The USB has
timing needs that may not always be filled by the Main PLL.
Both PLLs are disabled and powered off on reset. If the Alternate PLL is left disabled, the
USB clock can be supplied by PLL0 if everything is set up to provide 48 MHz to the USB
clock through that route. The source for each clock must be selected via the CLKSEL
registers and can be further reduced by clock dividers as needed.
PLL0 accepts an input clock frequency from either the IRC or the main oscillator. If only
the Main PLL is used, then its output frequency must be an integer multiple of all other
clocks needed in the system. PLL1 takes its input only from the main oscillator, requiring
an external crystal in the range of 10 to 25 MHz. In each PLL, the Current Controlled
Oscillator (CCO) operates in the range of 156 MHz to 320 MHz, so there are additional
dividers to bring the output down to the desired frequencies. The minimum output divider
value is 2, insuring that the output of the PLLs have a 50 % duty cycle.
If the USB is used, the possibilities for the CPU clock and other clocks will be limited by
the requirements that the frequency be precise and very low jitter, and that the PLL0
output must be a multiple of 48 MHz. Even multiples of 48 MHz that are within the
operating range of the PLL are 192 MHz and 288 MHz. Also, only the main oscillator in
conjunction with the PLL can meet the precision and jitter specifications for USB. It is due
to these limitations that the Alternate PLL is provided.
The alternate PLL accepts an input clock frequency from the main oscillator in the range
of 10 MHz to 25 MHz only. When used as the USB clock, the input frequency is multiplied
up to a multiple of 48 MHz (192 MHz or 288 MHz as described above).

7.36.3 Wake-up timer
The LPC408x/7x begin operation at power-up and when awakened from Power-down
mode by using the 12 MHz IRC oscillator as the clock source. This allows chip operation
to resume quickly. If the main oscillator or the PLL is needed by the application, software
will need to enable these features and wait for them to stabilize before they are used as a
clock source.
When the main oscillator is initially activated, the wake-up timer allows software to ensure
that the main oscillator is fully functional before the processor uses it as a clock source
and starts to execute instructions. This is important at power on, all types of reset, and
whenever any of the aforementioned functions are turned off for any reason. Since the
oscillator and other functions are turned off during Power-down mode, any wake-up of the
processor from Power-down mode makes use of the wake-up Timer.
The wake-up timer monitors the crystal oscillator to check whether it is safe to begin code
execution. When power is applied to the chip, or when some event caused the chip to exit
Power-down mode, some time is required for the oscillator to produce a signal of sufficient
amplitude to drive the clock logic. The amount of time depends on many factors, including
the rate of VDD(3V3) ramp (in the case of power on), the type of crystal and its electrical
characteristics (if a quartz crystal is used), as well as any other external circuitry (e.g.,
capacitors), and the characteristics of the oscillator itself under the existing ambient
conditions.
7.36.4 Power control
The LPC408x/7x support a variety of power control features. There are four special
modes of processor power reduction: Sleep mode, Deep-sleep mode, Power-down mode,
and Deep power-down mode. The CPU clock rate may also be controlled as needed by
changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider
value. This allows a trade-off of power versus processing speed based on application
requirements. In addition, the peripheral power control allows shutting down the clocks to
individual on-chip peripherals, allowing fine tuning of power consumption by eliminating all
dynamic power use in any peripherals that are not required for the application. Each of the
peripherals has its own clock divider which provides even better power control.
The integrated PMU (Power Management Unit) automatically adjusts internal regulators
to minimize power consumption during Sleep, Deep-sleep, Power-down, and Deep
power-down modes.
The LPC408x/7x also implement a separate power domain to allow turning off power to
the bulk of the device while maintaining operation of the RTC and a small set of registers
for storing data during any of the power-down modes.
7.36.4.1
Sleep mode
When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep
mode does not need any special sequence other than re-enabling the clock to the ARM
core.
In Sleep mode, execution of instructions is suspended until either a Reset or interrupt
occurs. Peripheral functions continue operation during Sleep mode and may generate
interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic
power used by the processor itself, memory systems and related controllers, and internal
buses.

32-bit ARM Cortex-M4 microcontroller
The DMA controller can continue to work in Sleep mode and has access to the peripheral
RAMs and all peripheral registers. The flash memory and the main SRAM are not
available in Sleep mode, they are disabled in order to save power.
Wake-up from Sleep mode will occur whenever any enabled interrupt occurs.
7.36.4.2
Deep-sleep mode
In Deep-sleep mode, the oscillator is shut down and the chip receives no internal clocks.
The processor state and registers, peripheral registers, and internal SRAM values are
preserved throughout Deep-sleep mode and the logic levels of chip pins remain static.
The output of the IRC is disabled but the IRC is not powered down to allow fast wake-up.
The RTC oscillator is not stopped because the RTC interrupts may be used as the
wake-up source. The PLL is automatically turned off and disconnected. The clock divider
registers are automatically reset to zero.
The Deep-sleep mode can be terminated and normal operation resumed by either a
Reset or certain specific interrupts that are able to function without clocks. Since all
dynamic operation of the chip is suspended, Deep-sleep mode reduces chip power
consumption to a very low value. Power to the flash memory is left on in Deep-sleep
mode, allowing a very quick wake-up.
Wake-up from Deep-sleep mode can initiated by the NMI, External Interrupts EINT0
through EINT3, GPIO interrupts, the Ethernet Wake-on-LAN interrupt, Brownout Detect,
an RTC Alarm interrupt, a USB input pin transition (USB activity interrupt), a CAN input
pin transition, or a Watchdog Timer time-out, when the related interrupt is enabled.
Wake-up will occur whenever any enabled interrupt occurs.
On wake-up from Deep-sleep mode, the code execution and peripherals activities will
resume after four cycles expire if the IRC was used before entering Deep-sleep mode. If
the main external oscillator was used, the code execution will resume when 4096 cycles
expire. PLL and clock dividers need to be reconfigured accordingly.
7.36.4.3
Power-down mode
Power-down mode does everything that Deep-sleep mode does but also turns off the
power to the IRC oscillator and the flash memory. This saves more power but requires
waiting for resumption of flash operation before execution of code or data access in the
flash memory can be accomplished.
When the chip enters Power-down mode, the IRC, the main oscillator, and all clocks are
stopped. The RTC remains running if it has been enabled and RTC interrupts may be
used to wake up the CPU. The flash is forced into Power-down mode. The PLLs are
automatically turned off and the clock selection multiplexers are set to use the system
clock sysclk (the reset state). The clock divider control registers are automatically reset to
zero. If the Watchdog timer is running, it will continue running in Power-down mode.
On the wake-up of Power-down mode, if the IRC was used before entering Power-down
mode, it will take IRC 60 s to start-up. After this four IRC cycles will expire before the
code execution can then be resumed if the code was running from SRAM. In the
meantime, the flash wake-up timer then counts 12 MHz IRC clock cycles to make the
100 s flash start-up time. When it times out, access to the flash will be allowed. Users
need to reconfigure the PLL and clock dividers accordingly.

7.36.4.4
Deep power-down mode
The Deep power-down mode can only be entered from the RTC block. In Deep
power-down mode, power is shut off to the entire chip with the exception of the RTC
module and the RESET pin.
To optimize power conservation, the user has the additional option of turning off or
retaining power to the 32 kHz oscillator. It is also possible to use external circuitry to turn
off power to the on-chip regulator via the VDD(REG)(3V3) pins and/or the I/O power via the
VDD(3V3) pins after entering Deep Power-down mode. Power must be restored before
device operation can be restarted.
The LPC408x/7x can wake up from Deep power-down mode via the RESET pin or an
alarm match event of the RTC.
7.36.4.5
Wake-up Interrupt Controller (WIC)
The WIC allows the CPU to automatically wake up from any enabled priority interrupt that
can occur while the clocks are stopped in Deep-sleep, Power-down, and Deep
power-down modes.
The WIC works in connection with the Nested Vectored Interrupt Controller (NVIC). When
the CPU enters Deep-sleep, Power-down, or Deep power-down mode, the NVIC sends a
mask of the current interrupt situation to the WIC. This mask includes all of the interrupts
that are both enabled and of sufficient priority to be serviced immediately. With this
information, the WIC simply notices when one of the interrupts has occurred and then it
wakes up the CPU.
The WIC eliminates the need to periodically wake up the CPU and poll the interrupts
resulting in additional power savings.
7.36.5 Peripheral power control
A power control for peripherals feature allows individual peripherals to be turned off if they
are not needed in the application, resulting in additional power savings.
7.36.6 Power domains
The LPC408x/7x provide two independent power domains that allow the bulk of the
device to have power removed while maintaining operation of the RTC and the backup
registers.
On the LPC408x/7x, I/O pads are powered by VDD(3V3), while VDD(REG)(3V3) powers the
on-chip voltage regulator which in turn provides power to the CPU and most of the
peripherals.
Depending on the LPC408x/7x application, a design can use two power options to
manage power consumption.
The first option assumes that power consumption is not a concern and the design ties the
VDD(3V3) and VDD(REG)(3V3) pins together. This approach requires only one 3.3 V power
supply for both pads, the CPU, and peripherals. While this solution is simple, it does not
support powering down the I/O pad ring “on the fly” while keeping the CPU and
peripherals alive.

LPC408x/7x

32-bit ARM Cortex-M4 microcontroller
The second option uses two power supplies; a 3.3 V supply for the I/O pads (VDD(3V3)) and
a dedicated 3.3 V supply for the CPU (VDD(REG)(3V3)). Having the on-chip voltage regulator
powered independently from the I/O pad ring enables shutting down of the I/O pad power
supply “on the fly” while the CPU and peripherals stay active.
The VBAT pin supplies power only to the RTC domain. The RTC requires a minimum of
power to operate, which can be supplied by an external battery. The device core power
(VDD(REG)(3V3)) is used to operate the RTC whenever VDD(REG)(3V3) is present. There is no
power drain from the RTC battery when VDD(REG)(3V3) is available and VDD(REG)(3V3) >
VBAT.

7.37 System control
7.37.1 Reset
Reset has four sources on the LPC408x/7x: the RESET pin, the Watchdog reset,
Power-On Reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a
Schmitt trigger input pin. Assertion of chip Reset by any source, once the operating
voltage attains a usable level, starts the Wake-up timer (see description in
Section 7.36.3), causing reset to remain asserted until the external Reset is de-asserted,
the oscillator is running, a fixed number of clocks have passed, and the flash controller
has completed its initialization.
When the internal Reset is removed, the processor begins executing at address 0, which
is initially the Reset vector mapped from the boot block. At that point, all of the processor
and peripheral registers have been initialized to predetermined values.
7.37.2 Brownout detection
The LPC408x/7x include 2-stage monitoring of the voltage on the VDD(REG)(3V3) pins. If this
voltage falls below 2.2 V (typical), the BOD asserts an interrupt signal to the Vectored
Interrupt Controller. This signal can be enabled for interrupt in the Interrupt Enable
Register in the NVIC in order to cause a CPU interrupt; if not, software can monitor the
signal by reading a dedicated status register.
The second stage of low-voltage detection asserts reset to inactivate the LPC408x/7x
when the voltage on the VDD(REG)(3V3) pins falls below 1.85 V (typical). This reset prevents
alteration of the flash as operation of the various elements of the chip would otherwise
become unreliable due to low voltage. The BOD circuit maintains this reset down below
1 V, at which point the power-on reset circuitry maintains the overall reset.
Both the 2.2 V and 1.85 V thresholds include some hysteresis. In normal operation, this
hysteresis allows the 2.2 V detection to reliably interrupt, or a regularly executed event
loop to sense the condition.
7.37.3 Code security (Code Read Protection - CRP)
This feature of the LPC408x/7x allows user to enable different levels of security in the
system so that access to the on-chip flash and use of the JTAG and ISP can be restricted.
When needed, CRP is invoked by programming a specific pattern into a dedicated flash
location. IAP commands are not affected by the CRP.
There are three levels of the Code Read Protection.
CRP1 disables access to chip via the JTAG and allows partial flash update (excluding
flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is
required and flash field updates are needed but all sectors can not be erased.
CRP2 disables access to chip via the JTAG and only allows full flash erase and update
using a reduced set of the ISP commands.
Running an application with level CRP3 selected fully disables any access to chip via the
JTAG pins and the ISP. This mode effectively disables ISP override using P2[10] pin, too.
It is up to the user’s application to provide (if needed) flash update mechanism using IAP
calls or call reinvoke ISP command to enable flash update via UART0.

CAUTION
If level three Code Read Protection (CRP3) is selected, no future factory testing can be
performed on the device.
7.37.4 APB interface
The APB peripherals are split into two separate APB buses in order to distribute the bus
bandwidth and thereby reducing stalls caused by contention between the CPU and the
GPDMA controller.
7.37.5 AHB multilayer matrix
The LPC408x/7x use an AHB multilayer matrix. This matrix connects the instruction
(I-code) and data (D-code) CPU buses of the ARM Cortex-M4 to the flash memory, the
main (32 kB) static RAM, and the Boot ROM. The GPDMA can also access all of these
memories. Additionally, the matrix connects the CPU system bus and all of the DMA
controllers to the various peripheral functions.
7.37.6 External interrupt inputs
The LPC408x/7x include up to 30 edge sensitive interrupt inputs combined with one level
sensitive external interrupt input as selectable pin function. The external interrupt input
can optionally be used to wake up the processor from Power-down mode.
7.37.7 Memory mapping control
The Cortex-M4 incorporates a mechanism that allows remapping the interrupt vector table
to alternate locations in the memory map. This is controlled via the Vector Table Offset
Register contained in the NVIC.
The vector table may be located anywhere within the bottom 1 GB of Cortex-M4 address
space. The vector table must be located on a 128 word (512 byte) boundary because the
NVIC on the LPC408x/7x is configured for 128 total interrupts.
7.38 Debug control
Debug and trace functions are integrated into the ARM Cortex-M4. Serial wire debug and
trace functions are supported in addition to a standard JTAG debug and parallel trace
functions. The ARM Cortex-M4 is configured to support up to eight breakpoints and four
watch points.

10.2 Peripheral power consumption
The supply current per peripheral is measured as the difference in supply current between
the peripheral block enabled and the peripheral block disabled in the PCONP register. All
other blocks are disabled and no code is executed. Measured on a typical sample at
Tamb = 25 C. The peripheral clock was set to PCLK = CCLK/4 with CCLK = 12 MHz,
48 MHz, and 120 MHz.
The combined current of several peripherals running at the same time can be less than
the sum of each individual peripheral current measured separately.
Table 12. Power consumption for individual analog and digital blocks
Tamb = 25 C; VDD(REG)(3V3) = VDD(3V3) = VDDA = 3.3 V; PCLK = CCLK/4.

The minimum clock cycle time, and therefore the maximum frequency of the SSP in master mode, is limited
by the pin electronics to the value given. The SSP block should not be configured to generate a clock faster
than that. At and below the maximum frequency, Tcy(clk) = (SSPCLKDIV  (1 + SCR)  CPSDVSR) / fmain.
The clock cycle time derived from the SPI bit rate Tcy(clk) is a function of the main clock frequency fmain, the
SSP peripheral clock divider (SSPCLKDIV), the SSP SCR parameter (specified in the SSP0CR0 register),
and the SSP CPSDVSR parameter (specified in the SSP clock prescale register).
[2]
Tamb = 40 C to 85 C; VDD(3V3) = 3.0 V to 3.6 V.
[3]
Tcy(clk) = 12  Tcy(PCLK). The maximum clock rate in slave mode is 1/12th of the PCLK rate.

Tamb = 25 C; VDD(3V3) = 3.3 V.

See the I2C-bus specification UM10204 for details.
[2]
Parameters are valid over operating temperature range unless otherwise specified.
[3]
tHD;DAT is the data hold time that is measured from the falling edge of SCL; applies to data in transmission
and the acknowledge.
[4]
A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the
VIH(min) of the SCL signal) to bridge the undefined region of the falling edge of SCL.
[5]
Cb = total capacitance of one bus line in pF.
[6]
The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA
output stage tf is specified at 250 ns. This allows series protection resistors to be connected in between the
SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf.
[7]
In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors
are used, designers should allow for this when considering bus timing.
[8]
The maximum tHD;DAT could be 3.45 s and 0.9 s for Standard-mode and Fast-mode but must be less than
the maximum of tVD;DAT or tVD;ACK by a transition time (see UM10204). This maximum must only be met if
the device does not stretch the LOW period (tLOW) of the SCL signal. If the clock stretches the SCL, the
data must be valid by the set-up time before it releases the clock.
[9]
tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in
transmission and the acknowledge.
[10] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement tSU;DAT =
250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period
of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next
data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus
specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time.

VDDA and VREFP should be tied to VDD(3V3) if the ADC and DAC are not used.
[2]
Conditions: VSSA = 0 V, VDDA = 3.3 V.
[3]
The ADC is monotonic, there are no missing codes.
[4]
The differential linearity error (ED) is the difference between the actual step width and the ideal step width.
See Figure 32.
[5]
The integral non-linearity (EL(adj)) is the peak difference between the center of the steps of the actual and
the ideal transfer curve after appropriate adjustment of gain and offset errors. See Figure 32.
[6]
The offset error (EO) is the absolute difference between the straight line which fits the actual curve and the
straight line which fits the ideal curve. See Figure 32.
[7]
The gain error (EG) is the relative difference in percent between the straight line fitting the actual transfer
curve after removing offset error, and the straight line which fits the ideal transfer curve. See Figure 32.
[8]
The absolute error (ET) is the maximum difference between the center of the steps of the actual transfer
curve of the non-calibrated ADC and the ideal transfer curve. See Figure 32.
[9]
In single-conversion mode.
[10] See Figure 33.
[11] 8-bit resolution is achieved by ignoring the lower four bits of the ADC conversion result.

13.2 Crystal oscillator XTAL input and component selection
The input voltage to the on-chip oscillators is limited to 1.8 V. If the oscillator is driven by a
clock in slave mode, it is recommended that the input be coupled through a capacitor with
Ci = 100 pF. To limit the input voltage to the specified range, choose an additional
capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave
mode, a minimum of 200 mV(RMS) is needed.

In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF
(Figure 40), with an amplitude between 200 mV(RMS) and 1000 mV(RMS). This
corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V.
The XTALOUT pin in this configuration can be left unconnected.
External components and models used in oscillation mode are shown in Figure 41 and in
Table 34 and Table 35. Since the feedback resistance is integrated on chip, only a crystal
and the capacitances CX1 and CX2 need to be connected externally in case of
fundamental mode oscillation (the fundamental frequency is represented by L, CL and
RS). Capacitance CP in Figure 41 represents the parallel package capacitance and should
not be larger than 7 pF. Parameters FOSC, CL, RS and CP are supplied by the crystal
manufacturer.

13.3 XTAL Printed-Circuit Board (PCB) layout guidelines
The crystal should be connected on the PCB as close as possible to the oscillator input
and output pins of the chip. Take care that the load capacitors Cx1, Cx2, and Cx3 in case of
third overtone crystal usage have a common ground plane. The external components
must also be connected to the ground plane. Loops must be made as small as possible in
order to keep the noise coupled in via the PCB as small as possible. Also parasitics
should stay as small as possible. Smaller values of Cx1 and Cx2 should be chosen
according to the increase in parasitics of the PCB layout.
13.4 Standard I/O pin configuration
Figure 42 shows the possible pin modes for standard I/O pins with analog input function:
•
•
•
•
•
Digital output driver: Open-drain mode enabled/disabled.
Digital input: Pull-up enabled/disabled.
Digital input: Pull-down enabled/disabled.
Digital input: Repeater mode enabled/disabled.
Analog input.
The default configuration for standard I/O pins is input with pull-up enabled. The weak
MOS devices provide a drive capability equivalent to pull-up and pull-down resistors.
