1. General description
The LPC4370 are ARM Cortex-M4 based microcontrollers for embedded applications
which include an ARM Cortex-M0 coprocessor and an ARM Cortex-M0 subsystem for
managing peripherals, 282 kB of SRAM, advanced configurable peripherals such as the
State Configurable Timer (SCTimer/PWM) and the Serial General Purpose I/O (SGPIO)
interface, two high-speed USB controllers, Ethernet, LCD, an external memory controller,
and multiple digital and analog peripherals, including a high-speed 12-bit ADC. The
LPC4370 operate at CPU frequencies of up to 204 MHz.
The ARM Cortex-M4 is a 32-bit core that offers system enhancements such as low power
consumption, enhanced debug features, and a high level of support block integration. The
ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture with
separate local instruction and data buses as well as a third bus for peripherals, and
includes an internal prefetch unit that supports speculative branching. The ARM
Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. A
hardware floating-point processor is integrated in the core.
The LPC4370 include an application ARM Cortex-M0 coprocessor and a second ARM
Cortex-M0 subsystem for managing the SGPIO and SPI peripherals. The ARM Cortex-M0
core is an energy-efficient and easy-to-use 32-bit core which is code- and tool-compatible
with the Cortex-M4 core. Both Cortex-M0 cores offer up to 204 MHz performance with a
simple instruction set and reduced code size. In LPC43x0, the Cortex-M0 coprocessor
hardware multiply is implemented as a 32-cycle iterative multiplier.

32-bit ARM Cortex-M4/M0 microcontroller
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 allow for concurrent code and data
accesses from different slave ports.
The LPC4370 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.
An ARM Cortex-M0 coprocessor is included in the LPC4370, capable of off-loading the
main ARM Cortex-M4 application processor. Most peripheral interrupts are connected to
both processors. The processors communicate with each other via an interprocessor
communication protocol.
7.2 ARM Cortex-M4 processor
The ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture
with separate local instruction and data buses as well as a third bus for peripherals, and
includes an internal prefetch unit that supports speculative branching. The ARM
Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. A
hardware floating-point processor is integrated in the core. The processor includes a
NVIC with up to 53 interrupts.
7.3 ARM Cortex-M0 processors
The ARM Cortex-M0 processors are general purpose, 32-bit microprocessors, which offer
high performance and very low power consumption. The ARM Cortex-M0 processor uses
a 3-stage pipeline von Neumann architecture and a small but powerful instruction set
providing high-end processing hardware. The processors each incorporate an NVIC with
32 interrupts. In LPC43x0, the Cortex-M0 coprocessor hardware multiply is implemented
as a 32-cycle iterative multiplier.
7.3.1 ARM Cortex-M0 coprocessor
The M0 coprocessor resides on the same AHB multi-layer matrix as the main Cortex-M0
core. The coprocessor can be used to off-load multiple tasks from the main Cortex-M4
processor.
7.3.2 ARM Cortex-M0 subsytem
The Cortex-M0 subsystem can be used to manage the SGPIO and SPI peripherals on the
M0 subsystem multilayer matrix but any other peripheral as well. The M0 subsystem is
separated by a bridge from the main AHB matrix. The M0 subsystem AHB matrix has two
SRAM blocks which allows to run the Cortex-M0 subsytem at full speed independently
from the main matrix.
One application of using the subsystem is to reduce power, for example when the main
matrix runs at a very low speed and the M0 subsystem monitors activity and increases the
main matrix speed when needed.

LPC4370
NXP Semiconductors
32-bit ARM Cortex-M4/M0 microcontroller
One of the two SRAM blocks connected to the subsystem AHB matrix is typically used for
code running on the M0 subsystem and the other SRAM block for data. This allows other
bus masters to access the data SRAM without interrupting the M0 processor instruction
fetches and thereby stalling the M0 subsystem.
The M0 subsystem matrix runs at an asynchronous speed from the main matrix. This
allows to operate the SGPIO at any desired frequency. The M0 subsystem can control the
SGPIO in a deterministic way, without incurring latency that occurs when the M4 controls
the SGPIO through a bridge.
7.4 Interprocessor communication
The ARM Cortex-M4 and ARM Cortex-M0 interprocessor communication is based on
using shared SRAM as mailbox and one processor raising an interrupt on the other
processor's NVIC, for example after it has delivered a new message in the mailbox. The
receiving processor can reply by raising an interrupt on the sending processor's NVIC to
acknowledge the message.

NXP Semiconductors
32-bit ARM Cortex-M4/M0 microcontroller
Each ARM Cortex-M0 coprocessor has its own NVIC with 32 vectored interrupts. Most
peripheral interrupts are shared between the two Cortex-M0cores and the Cortex-M4
NVICs.
7.6.1 Features
• ARM Cortex-M4 NVIC:
– Controls system exceptions and peripheral interrupts.
– Up to 53 vectored interrupts.
– Eight programmable interrupt priority levels with hardware priority level masking.
– Relocatable vector table.
– Non-Maskable Interrupt (NMI).
– Software interrupt generation.
• ARM Cortex-M0 and ARM Cortex-M0 subsystem NVIC:
– Control system exceptions and peripheral interrupts.
– Up to 32 vectored interrupts.
– Four programmable priority levels with hardware priority level masking.
7.6.2 Interrupt sources
Each peripheral device has one interrupt line connected to the NVIC but may have several
interrupt flags. Individual interrupt flags may also represent more than one interrupt
source.
7.7 System Tick timer (SysTick)
The ARM Cortex-M4 includes a system tick timer (SysTick) that is intended to generate a
dedicated SYSTICK exception at a 10 ms interval.
Remark: The SysTick is not included in the ARM Cortex-M0 core.
7.8 Event router
The event router combines various internal signals, interrupts, and the external interrupt
pins (WAKEUP[3:0]) to create an interrupt in the NVIC if enabled and to create a wake-up
signal to the ARM core and the CCU for waking up from Sleep, Deep-sleep, Power-down,
and Deep power-down modes. Individual events can be configured as edge or level
sensitive and can be enabled or disabled in the event router. The event router can be
battery powered.
The following events if enabled in the event router can create a wake-up signal and/or an
interrupt:

7.10 System Tick timer (SysTick)
The ARM Cortex-M4 includes a system tick timer (SYSTICK) that is intended to generate
a dedicated SYSTICK exception at a 10 ms interval.
7.11 On-chip static RAM
The LPC4370 support 200 kB local SRAM and an additional 64 kB AHB SRAM with
separate bus master access for higher throughput and individual power control for low
power operation. See Section 7.23.9.1 “Memory retention in Power-down modes”.
7.12 In-System Programming (ISP)
In-System programming (ISP) is programming or reprogramming the on-chip SRAM
memory, using the boot loader software and the USART0 serial port. This can be done
when the part resides in the end-user board. ISP allows to load data into on-chip SRAM
and execute code from on-chip SRAM.
7.13 Boot ROM
The internal ROM memory is used to store the boot code of the LPC4370. After a reset,
the ARM processor will start its code execution from this memory.
The boot ROM memory includes the following features:
• ROM memory size is 64 kB.
• Supports booting from UART interfaces and external static memory such as NOR
flash, SPI flash, quad SPI flash.
• Includes APIs for OTP programming.
• Includes a flexible USB device stack that supports Human Interface Device (HID),
Mass Storage Class (MSC), and Device Firmware Upgrade (DFU) drivers.
Several boot modes are available depending on the values of the OTP bits BOOT_SRC. If
the OTP memory is not programmed or the BOOT_SRC bits are all zero, the boot mode is
determined by the states of the boot pins P2_9, P2_8, P1_2, and P1_1.

NXP Semiconductors
32-bit ARM Cortex-M4/M0 microcontroller
7.15 One-Time Programmable (OTP) memory
The OTP provides 64-bit + 256 bit of memory for general purpose use.
7.16 General Purpose I/O (GPIO)
The LPC4370 provide 8 GPIO ports with up to 31 GPIO pins each.
Device pins that are not connected to a specific peripheral function are controlled by the
GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate
registers allow setting or clearing any number of outputs simultaneously. The value of the
output register may be read back as well as the current state of the port pins.
All GPIO pins default to inputs with pull-up resistors enabled on reset.
7.16.1 Features
• Accelerated GPIO functions:
– GPIO registers are located on the AHB so that the fastest possible I/O timing can
be achieved.
– Mask registers allow treating sets of port bits as a group, leaving other bits
unchanged.
– All GPIO registers are byte and half-word addressable.
– Entire port value can be written in one instruction.
• Bit-level set and clear registers allow a single instruction set or clear of any number of
bits in one port.
• Direction control of individual bits.
• All I/O default to inputs after reset.
• Up to eight GPIO pins can be selected from all GPIO pins to create an edge- or
level-sensitive GPIO interrupt request (GPIO interrupts).
• Two GPIO group interrupts can be triggered by any pin or pins in each port (GPIO
group0 and group1 interrupts).
7.17 Configurable digital peripherals
7.17.1 State Configurable Timer (SCT) subsystem
The SCT allows a wide variety of timing, counting, output modulation, and input capture
operations. The inputs and outputs of the SCT are shared with the capture and match
inputs/outputs of the 32-bit general purpose counter/timers.
The SCT can be configured as two 16-bit counters or a unified 32-bit counter. In the
two-counter case, in addition to the counter value the following operational elements are
independent for each half:
• State variable.
• Limit, halt, stop, and start conditions.
• Values of Match/Capture registers, plus reload or capture control values.

serial stream processing.
7.17.2.1
Features
• Each SGPIO input/output slice can be used to perform a serial to parallel or parallel to
serial data conversion.
• 16 SGPIO input/output slices each with a 32-bit FIFO that can shift the input value
from a pin or an output value to a pin with every cycle of a shift clock.

7.18 AHB peripherals
7.18.1 General Purpose DMA (GPDMA)
The DMA controller allows peripheral-to memory, memory-to-peripheral,
peripheral-to-peripheral, and memory-to-memory transactions. Each DMA stream
provides unidirectional serial DMA transfers for a single source and destination. For
example, a bidirectional port requires one stream for transmit and one for receives. The
source and destination areas can each be either a memory region or a peripheral for
master 1, but only memory for master 0.
7.18.1.1
Features
• Eight DMA channels. Each channel can support an unidirectional transfer.
• 16 DMA request lines.
• Single DMA and burst DMA request signals. Each peripheral connected to the DMA
Controller can assert either a burst DMA request or a single DMA request. The DMA
burst size is set by programming the DMA Controller.
• Memory-to-memory, memory-to-peripheral, peripheral-to-memory, and
peripheral-to-peripheral transfers are supported.
• Scatter or gather DMA is supported through the use of linked lists. This means that
the source and destination areas do not have to occupy contiguous areas of memory.
• Hardware DMA channel priority.
• AHB slave DMA programming interface. The DMA Controller is programmed by
writing to the DMA control registers over the AHB slave interface.
• Two AHB bus masters for transferring data. These interfaces transfer data when a
DMA request goes active. Master 1 can access memories and peripherals (except
SGPIO and SPI). Master 0 can access memories on the main AHB matrix and
peripherals and memories on the M0SUB bus.
• 32-bit AHB master bus width.
• Incrementing or non-incrementing addressing for source and destination.
• Programmable DMA burst size. The DMA burst size can be programmed to more
efficiently transfer data.
• Internal four-word FIFO per channel.
• Supports 8, 16, and 32-bit wide transactions.
• Big-endian and little-endian support. The DMA Controller defaults to little-endian
mode on reset.
• An interrupt to the processor can be generated on a DMA completion or when a DMA
error has occurred.
• Raw interrupt status. The DMA error and DMA count raw interrupt status can be read
prior to masking.
7.18.2 SPI Flash Interface (SPIFI)
The SPI Flash Interface allows low-cost serial flash memories to be connected to the ARM
Cortex-M4 processor with little performance penalty compared to parallel flash devices
with higher pin count.

LPC4370
NXP Semiconductors
32-bit ARM Cortex-M4/M0 microcontroller
After a few commands configure the interface at startup, the entire flash content is
accessible as normal memory using byte, halfword, and word accesses by the processor
and/or DMA channels. Erasure and programming are handled by simple sequences of
commands.
Many serial flash devices use a half-duplex command-driven SPI protocol for device setup
and initialization and then move to a half-duplex, command-driven 4-bit protocol for
normal operation. Different serial flash vendors and devices accept or require different
commands and command formats. SPIFI provides sufficient flexibility to be compatible
with common flash devices and includes extensions to help insure compatibility with future
devices.

7.20 Counter/timers and motor control
7.20.1 General purpose 32-bit timers/external event counters
The LPC4370 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.
7.20.1.1
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.
7.20.2 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.
7.20.3 Quadrature Encoder Interface (QEI)
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.

The repetitive interrupt timer provides a free-running 32-bit counter which is compared to
a selectable value, generating an interrupt when a match occurs. Any bits of the
timer/compare can be masked such that they do not contribute to the match detection.
The repetitive interrupt timer can be used to create an interrupt that repeats at
predetermined intervals.
7.20.4.1
Features
• 32-bit counter. Counter can be free-running or be reset by a generated interrupt.
• 32-bit compare value.
• 32-bit compare mask. An interrupt is generated when the counter value equals the
compare value, after masking. This allows for combinations not possible with a simple
compare.

7.22 Peripherals in the RTC power domain
7.22.1 RTC
The Real Time Clock (RTC) is a set of counters for measuring time when system power is
on, and optionally when it is off. It uses very little power when its registers are not being
accessed by the CPU, especially reduced power modes. The RTC is clocked by a
separate 32 kHz oscillator that produces a 1 Hz internal time reference. The RTC is
powered by its own power supply pin, VBAT.
7.22.1.1
Features
• Measures the passage of time to maintain a calendar and clock. Provides seconds,
minutes, hours, day of month, month, year, day of week, and day of year.
• Ultra-low power design to support battery powered systems. Uses power from the
CPU power supply when it is present.
•
•
•
•
•
Dedicated battery power supply pin.
RTC power supply is isolated from the rest of the chip.
Calibration counter allows adjustment to better than 1 sec/day with 1 sec resolution.
Periodic interrupts can be generated from increments of any field of the time registers.
Alarm interrupt can be generated for a specific date/time.
7.22.2 Alarm timer
The alarm timer is a 16-bit timer and counts down at 1 kHz from a preset value generating
alarms in intervals of up to 1 min. The counter triggers a status bit when it reaches 0x00
and asserts an interrupt if enabled.
The alarm timer is part of the RTC power domain and can be battery powered.
7.23 System control

The following settings are controlled in the configuration register block:
•
•
•
•
•
•
•
BOD trip settings
Oscillator output

NXP Semiconductors
32-bit ARM Cortex-M4/M0 microcontroller
7.23.2 System Control Unit (SCU)
The system control unit determines the function and electrical mode of the digital pins. By
default function 0 is selected for all pins with pull-up enabled. For pins that support a
digital and analog function, the ADC function select registers in the SCU enable the
analog function.
A separate set of analog I/Os for the ADCs and the DAC as well as most USB pins are
located on separate pads and are not controlled through the SCU.
In addition, the clock delay register for the SDRAM EMC_CLK pins and the registers that
select the pin interrupts are located in the SCU.
7.23.3 Clock Generation Unit (CGU)
The Clock Generator Unit (CGU) generates several base clocks. The CGU outputs are
unrelated in frequency and phase and can have different clock sources within the CGU.
One CGU output is routed to the CLKOUT pins.
Within each clock area there may be multiple branch clocks, which offers very flexible
control for power-management purposes. All branch clocks are outputs of one of two
Clock Control Units (CCUs) and can be controlled independently. Branch clocks derived
from the same base clock are synchronous in frequency and phase.
7.23.4 Internal RC oscillator (IRC)
The IRC is used as the clock source for the WWDT and/or as the clock that drives the
PLLs 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 LPC4370 use the IRC as the clock source. Software
may later switch to one of the other available clock sources.
7.23.5 PLL0USB (for USB0)
PLL0 is a dedicated PLL for the USB0 High-speed controller.
PLL0 accepts an input clock frequency from an external oscillator in the range of 14 kHz
to 25 MHz. The input frequency is multiplied up to a high frequency with a Current
Controlled Oscillator (CCO). The CCO operates in the range of 4.3 MHz to 550 MHz.
7.23.6 PLL0AUDIO (for audio)
The audio PLL PLL0AUDIO is a general purpose PLL with a very small step size. This
PLL accepts an input clock frequency derived from an external oscillator or internal IRC.
The input frequency is multiplied up to a high frequency with a Current Controlled
Oscillator (CCO). A sigma-delta converter modulates the PLL divider ratios to obtain the
desired output frequency. The output frequency can be set as a multiple of the sampling
frequency fs to 32fs, 64fs, 128  fs, 256  fs, 384  fs, 512  fs and the sampling
frequency fs can range from 16 kHz to 192 kHz (16, 22.05, 32, 44.1, 48, 96,192) kHz.
Many other frequencies are possible as well.
7.23.7 System PLL1
The PLL1 accepts an input clock frequency from an external oscillator in the range of
1 MHz to 25 MHz. The input frequency is multiplied up to a high frequency with a Current
Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32. The CCO

32-bit ARM Cortex-M4/M0 microcontroller
operates in the range of 156 MHz to 320 MHz, so there is an additional divider in the loop
to keep the CCO within its frequency range while the PLL is providing the desired output
frequency. The output divider may be set to divide by 2, 4, 8, or 16 to produce the output
clock. Since the minimum output divider value is 2, it is insured that the PLL output has a
50 % duty cycle. The PLL is turned off and bypassed following a chip reset and may be
enabled by software. The program must configure and activate the PLL, wait for the PLL
to lock, and then connect to the PLL as a clock source. The PLL settling time is 100 s.
7.23.8 Reset Generation Unit (RGU)
The RGU allows generation of independent reset signals for individual blocks and
peripherals on the LPC4370.
7.23.9 Power control
The LPC4370 feature several independent power domains to control power to the core
and the peripherals (see Figure 7). The RTC and its associated peripherals (the alarm
timer, the CREG block, the OTP controller, the back-up registers, and the event router)
are located in the RTC power-domain which can be powered by a battery supply or the
main regulator. A power selector switch ensures that the RTC block is always powered on.

Power Management Controller (PMC)
The PMC controls the power to the cores, peripherals, and memories.
The LPC4370 support the following power modes in order from highest to lowest power
consumption:
1. Active mode
2. Sleep mode
3. Power-down modes:
a. Deep-sleep mode
b. Power-down mode
c. Deep power-down mode
Active mode and sleep mode apply to the state of the core. In a multi-core system, any
core can be in active or sleep mode independently of the other core.
If the core is in Active mode, it is fully operational and can access peripherals and
memories as configured by software. If the core is in Sleep mode, it receives no clocks,
but peripherals and memories can remain running.
Any core can enter sleep mode from active mode independently of the other cores and
while the other cores remain in active mode or are in sleep mode.
Power-down modes apply to the entire system. In the Power-down modes, all cores and
all peripherals except for peripherals in the always-on power domain are shut down.
Memories can remain powered for retaining memory contents as defined by the individual
power-down mode.
Any core in active mode can put the part into one of the three power down modes if the
core is enabled to do so. If both the M4 core and the two M0 cores are enabled for
power-down, then the system enters power-down only once all three cores have received
a WFI or WFE instruction.
Wake-up from sleep mode is caused by an interrupt or event in the core’s NVIC. An
interrupt is captured in the NVIC and an event is captured in the Event router. Both cores
can wake up from sleep mode independently of each other.

LPC4370
NXP Semiconductors
32-bit ARM Cortex-M4/M0 microcontroller
Wake-up from the Power-down modes, Deep-sleep, Power-down, and Deep power-down,
is caused by an event on the WAKEUP pins or an event from the RTC or alarm timer.
When waking up from Deep power-down mode, the part resets and attempts to boot. After
booting, the M4 core is in active mode and both M0 cores remain in the reset state until
the reset is released by software.
7.24 Serial Wire Debug/JTAG
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.
The ARM Cortex-M0 coprocessors support JTAG boundary scan only.

The following applies to the limiting values:
a) This product includes circuitry designed for the protection of its internal devices from the damaging effects of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maximum.
b) Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS unless
otherwise noted.
c) The limiting values are stress ratings only and operating the part at these values is not recommended and proper operation is not
guaranteed. The conditions for functional operation are specified in Table 10.
[2]
Including voltage on outputs in 3-state mode.
[3]
The peak current is limited to 25 times the corresponding maximum current.
[4]
Dependent on package type.

9. Thermal characteristics
The average chip junction temperature, Tj (C), can be calculated using the following
equation:
T j = T amb +  P D  R th  j – a  
(1)
• Tamb = ambient temperature (C),
• Rth(j-a) = the package junction-to-ambient thermal resistance (C/W)
• PD = sum of internal and I/O power dissipation
The internal power dissipation is the product of IDD and VDD. The I/O power dissipation of
the I/O pins is often small and many times can be negligible. However it can be significant
in some applications.

10.2 Peripheral power consumption
The typical power consumption at T = 25 C for each individual peripheral is measured as
follows:
1. Enable all branch clocks and measure the current IDD(REG)(3V3).
2. Disable the branch clock to the peripheral to be measured and keep all other branch
clocks enabled.
3. Calculate the difference between measurement 1 and 2. The result is the peripheral
power consumption.

[3]
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.
[4]
Cb = total capacitance of one bus line in pF. If mixed with Hs-mode devices, faster fall times are allowed.
[5]
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.
[6]
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.
[7]
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. 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.
[8]
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.
[9]
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.

11.15 SGPIO timing
The following considerations apply to SGPIO timing:
• SGPIO input signals are synchronized by the internal clock SGPIO_CLOCK. To
guarantee that no samples are missed, all input signals should have a duration of at
least one SGPIO_CLOCK cycle plus the set-up and hold times.
• When an external clock input is used to generate output data, synchronization causes
a latency of at least one SGPIO_CLOCK cycle. The maximum output data rate is one
output every two SGPIO_CLOCK cycles.
• Synchronization also causes a latency of one SGPIO_CLOCK cycle when sampling
several inputs. This may cause inputs with very similar timings to be sampled with a
difference of one SGPIO_CLOCK cycle.

The ADC is monotonic, there are no missing codes.
[2]
The differential linearity error (ED) is the difference between the actual step width and the ideal step width. See Figure 38.
[3]
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 38.
[4]
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 38.
[5]
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 38.
[6]
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 38.
[7]
Tamb = 25 C; maximum sampling frequency fs = 4.5 MHz and analog input capacitance Cia = 2 pF.
[8]
Input resistance Ri depends on the sampling frequency fs: Ri = 2 k + 1 / (fs  Cia).

13.2 Crystal oscillator
The crystal oscillator is controlled by the XTAL_OSC_CTRL register in the CGU (see
LPC43xx user manual).
The crystal 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 PLL.
The oscillator can operate in one of two modes: slave mode and oscillation mode.
• In slave mode the input clock signal should be coupled by means of a capacitor of
100 pF (CC in Figure 40), with an amplitude of at least 200 mV (rms). The XTAL2 pin
in this configuration can be left unconnected.
• External components and models used in oscillation mode are shown in Figure 41,
and in Table 43 and Table 44. 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 FC, CL, RS and CP are
supplied by the crystal manufacturer.

13.3 RTC oscillator
In the RTC oscillator circuit, only the crystal (XTAL) and the capacitances CRTCX1 and
CRTCX2 need to be connected externally. Typical capacitance values for CRTCX1 and
CRTCX2 are CRTCX1/2 = 20 (typical)  4 pF.
An external clock can be connected to RTCX1 if RTCX2 is left open. The recommended
amplitude of the clock signal is Vi(RMS) = 100 mV to 200 mV with a coupling capacitance of
5 pF to 10 pF. Vi(RMS) must be lower than 450 mV. See Figure 40 for a similar slave-mode
set-up that uses the crystal oscillator.

13.4 XTAL and RTCX Printed Circuit Board (PCB) layout guidelines
Connect the crystal 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. Also connect the external components to the
ground plain. To keep the noise coupled in via the PCB as small as possible, make loops
and parasitics as small as possible. Choose smaller values of Cx1 and Cx2 if parasitics
increase in the PCB layout.

LPC4370
NXP Semiconductors
32-bit ARM Cortex-M4/M0 microcontroller
On the LPC4370, USBn_VBUS pins are 5 V tolerant only when VDDIO is applied and at
operating voltage level. Therefore, if the USBn_VBUS function is connected to the USB
connector and the device is self-powered, the USBn_VBUS pins must be protected for
situations when VDDIO = 0 V.
If VDDIO is always at operating level while VBUS = 5 V, the USBn_VBUS pin can be
connected directly to the VBUS pin on the USB connector.
For systems where VDDIO can be 0 V and VBUS is directly applied to the USBn_VBUS
pins, precautions must be taken to reduce the voltage to below 3.6 V, which is the
maximum allowable voltage on the USBn_VBUS pins in this case.
One method is to use a voltage divider to connect the USBn_VBUS pins to VBUS on the
USB connector. The voltage divider ratio should be such that the USB_VBUS pin will be
greater than 0.7VDDIO to indicate a logic HIGH while below the 3.6 V allowable maximum
voltage.
For the following operating conditions
VBUSmax = 5.25 V
VDDIO = 3.6 V,
the voltage divider should provide a reduction of 3.6 V/5.25 V or ~0.686 V.
For bus-powered devices, a regulator powered by USB can provide 3.3 V to VDDIO
whenever bus power is present and ensure that power to the USBn_VBUS pins is always
present when the 5 V VBUS signal is applied. See Figure 46.
Remark: Applying 5 V to the USBn_VBUS pins for a short time while the regulator ramps
up might compromise the long-term reliability of the part but does not affect its function.

13.8 Minimizing interference between digital signals and 12-bit ADC
signals
To reduce interference from digital signals to the high-speed 12-bit ADC inputs, do not
configure digital pins that are pinned out close to the ADC signals as outputs when using
the 12-bit ADC. For the BGA256 package, the pins with interfering signals are shown in
Table 45.

13.9 12-bit ADCHS input selection
The high-speed, 12-bit ADCHS operates with an internally generated 1.2 V power supply.
The input range for an ADC channel is 800 mV (peak-to-peak) in a band from 0 V to 1.2 V.
The input range Vin_pos is defined by Vin_pos = Vin_neg +/- 400 mV where Vin_neg can
be either generated internally or supplied by the external pin ADCHS_NEG.
The internally generated reference voltage is Vin_neg = 500 mV making the allowed input
voltage Vin_pos on any ADC channel 100 mV  Vin_pos  900 mV. See Figure 48.

For the internally generated negative reference voltage Vin_neg = 500 mV, one of the
following circuits are recommended for the ADC channel input:
1. Inverting single-ended with gain = 1 or for input range 0 V to 3.3 V
2. Non-inverting single-ended with gain = 1
3. Non-inverting singe-ended for input range 0 V to 3.3 V

13.9.1 Inverting single-ended circuit
For the inverting single-ended circuit only one op-amp is needed. A 1.24 V shunt voltage
reference is used for creating an offset voltage of 450 mV. The disadvantage is that the
signal output of the circuit is inverted. However, this can be easily solved in software by
subtracting the ADC output from 4095, which is the maximum value of the 12-bit result.

13.9.2 Non-inverting single-ended circuit with gain = 1
The advantage of having a non-inverting circuit comes at the cost of adding an additional
op-amp for a high-impedance voltage reference to prevent the reference level being
influenced by the input signal. This circuit is recommended for an input voltage from
100 mV to 800 mV using the internal negative reference voltage.
