Product data sheet
1. General description
The LPC1311/13/42/43 are ARM Cortex-M3 based microcontrollers for embedded
applications featuring a high level of integration and low power consumption. The ARM
Cortex-M3 is a next generation core that offers system enhancements such as enhanced
debug features and a higher level of support block integration.
The LPC1311/13/42/43 operate at CPU frequencies of up to 72 MHz. The ARM
Cortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture with
separate local instruction and data buses as well as a third bus for peripherals. The ARM
Cortex-M3 CPU also includes an internal prefetch unit that supports speculative
branching.
The peripheral complement of the LPC1311/13/42/43 includes up to 32 kB of flash
memory, up to 8 kB of data memory, USB Device (LPC1342/43 only), one Fast-mode Plus
I2C-bus interface, one UART, four general purpose timers, and up to 42 general purpose
I/O pins.
Remark: The LPC1311/13/42/43 series consists of the LPC1300 series (parts
LPC1311/13/42/43) and the LPC1300L series (parts LPC1311/01 and LPC1313/01). The
LPC1300L series features the following enhancements over the LPC1300 series:
•
•
•
•

5 V tolerant pad. See Figure 37 for pad characteristics. RESET functionality is not available in Deep power-down mode. Use the
WAKEUP pin to reset the chip and wake up from Deep power-down mode. An external pull-up resistor is required on this pin for the
Deep power-down mode.

5 V tolerant pad providing digital I/O functions with configurable pull-up/pull-down resistors, configurable hysteresis, and analog input.
When configured as a ADC input, digital section of the pad is disabled and the pin is not 5 V tolerant (see Figure 36).
[6]
Pad provides USB functions. It is designed in accordance with the USB specification, revision 2.0 (Full-speed and Low-speed mode
only). This pad is not 5 V tolerant.
[7]
When the system oscillator is not used, connect XTALIN and XTALOUT as follows: XTALIN can be left floating or can be grounded
(grounding is preferred to reduce susceptibility to noise). XTALOUT should be left floating.

LPC1311/13/42/43
NXP Semiconductors
32-bit ARM Cortex-M3 microcontroller
7. Functional description
7.1 Architectural overview
The ARM Cortex-M3 includes three AHB-Lite buses: the system bus, the I-code bus, and
the D-code bus (see Figure 1). The I-code and D-code core buses are faster than the
system bus and are used similarly to 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.
7.2 ARM Cortex-M3 processor
The ARM Cortex-M3 is a general purpose, 32-bit microprocessor, which offers high
performance and very low power consumption. The ARM Cortex-M3 offers many new
features, including a Thumb-2 instruction set, low interrupt latency, hardware multiply and
divide, interruptible/continuable multiple load and store instructions, automatic state save
and restore for interrupts, tightly integrated interrupt controller, and multiple core buses
capable of simultaneous accesses.
Pipeline techniques are employed so that all parts of the processing and memory systems
can operate continuously. Typically, while one instruction is being executed, its successor
is being decoded, and a third instruction is being fetched from memory.
The ARM Cortex-M3 processor is described in detail in the Cortex-M3 Technical
Reference Manual which is available on the official ARM website.
7.3 On-chip flash program memory
The LPC1311/13/42/43 contain 32 kB (LPC1313 and LPC1343), 16 kB (LPC1342), or
8 kB (LPC1311) of on-chip flash memory.
7.4 On-chip SRAM
The LPC1311/13/42/43 contain a total of 8 kB (LPC1343 and LPC1313) or 4 kB (LPC1342
and LPC1311) on-chip static RAM memory.
7.5 Memory map
The LPC1311/13/42/43 incorporate several distinct memory regions. Figure 6 shows the
overall map of the entire address space from the user program viewpoint following reset.
The interrupt vector area supports address remapping.
The AHB peripheral area is 2 MB in size and is divided to allow for up to 128 peripherals.
The APB peripheral area is 512 kB in size and is divided to allow for up to 32 peripherals.
Each peripheral of either type is allocated 16 kB of space. This allows simplifying the
address decoding for each peripheral.

32-bit ARM Cortex-M3 microcontroller
7.6.1 Features
• Controls system exceptions and peripheral interrupts.
• On the LPC1311/13/42/43, the NVIC supports up to 17 vectored interrupts. In
addition, up to 40 of the individual GPIO inputs are NVIC-vector capable.
• 8 programmable interrupt priority levels, with hardware priority level masking
• Relocatable vector table.
• Software interrupt generation.
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.
Any GPIO pin (total of up to 42 pins) regardless of the selected function, can be
programmed to generate an interrupt on a level, or rising edge or falling edge, or both.
7.7 IOCONFIG block
The IOCONFIG 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 interrupt(s) being enabled. Activity of any enabled peripheral function that is
not mapped to a related pin should be considered undefined.
7.8 Fast general purpose parallel I/O
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. Multiple outputs
can be set or cleared in one write operation.
LPC1311/13/42/43 use accelerated GPIO functions:
• GPIO block is a dedicated AHB peripheral so that the fastest possible I/O timing can
be achieved.
• Entire port value can be written in one instruction.
Additionally, any GPIO pin (total of up to 42 pins) providing a digital function can be
programmed to generate an interrupt on a level, a rising or falling edge, or both.
7.8.1 Features
• Bit level port registers allow a single instruction to set or clear any number of bits in
one write operation.
• Direction control of individual bits.
• All I/O default to inputs with pull-up resistors enabled after reset with the exception of
the I2C-bus pins PIO0_4 and PIO0_5.
• Pull-up/pull-down resistor configuration can be programmed through the IOCONFIG
block for each GPIO pin.

NXP Semiconductors
32-bit ARM Cortex-M3 microcontroller
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.

period.
• Optional windowed operation requires reload to occur between a minimum and
maximum time period, both programmable.
• Optional warning interrupt can be generated at a programmable time prior to
watchdog time-out.
• Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be
disabled.
•
•
•
•

Flag to indicate watchdog reset.
Programmable 24-bit timer with internal prescaler.
Selectable time period from (Tcy(WDCLK) × 256 × 4) to (Tcy(WDCLK) × 224 × 4) in
multiples of Tcy(WDCLK) × 4.
• The Watchdog Clock (WDCLK) source can be selected from the IRC or the dedicated
watchdog oscillator (WDO). This gives a wide range of potential timing choices of
watchdog operation under different power conditions.
7.18 Clocking and power control
7.18.1 Integrated oscillators
The LPC1311/13/42/43 include three independent oscillators. These are the system
oscillator, the Internal RC oscillator (IRC), and the watchdog oscillator. Each oscillator can
be used for more than one purpose as required in a particular application.
Following reset, the LPC1311/13/42/43 will operate from the internal RC oscillator until
switched by software. This allows systems to operate without any external crystal and the
bootloader code to operate at a known frequency.
See Figure 7 for an overview of the LPC1311/13/42/43 clock generation.

LPC1311/13/42/43
NXP Semiconductors
32-bit ARM Cortex-M3 microcontroller
Upon power-up, any chip reset, or wake-up from Deep power-down mode, the
LPC1311/13/42/43 use the IRC as the clock source. Software may later switch to one of
the other available clock sources.
7.18.1.2
System oscillator
The system oscillator can be used as the clock source for the CPU, with or without using
the PLL. On the LPC1342/43, the system oscillator must be used to provide the clock
source to USB.
The system 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
system PLL.
7.18.1.3
Watchdog oscillator
The watchdog oscillator can be used as a clock source that directly drives the CPU, the
watchdog timer, or the CLKOUT pin. The watchdog oscillator nominal frequency is
programmable between 7.8 kHz and 1.7 MHz. The frequency spread over processing and
temperature is ±40 % (see also Table 16).
7.18.2 System PLL and USB PLL
The LPC1342/43 contain a system PLL and a dedicated PLL for generating the 48 MHz
USB clock. The LPC131x contain the system PLL only. The system and USB PLLs are
identical.
The PLL accepts an input clock frequency in the range of 10 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 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. The PLL output
frequency must be lower than 100 MHz. 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 μs.
7.18.3 Clock output
The LPC1311/13/42/43 features a clock output function that routes the IRC oscillator, the
system oscillator, the watchdog oscillator, or the main clock to an output pin.
7.18.4 Wake-up process
The LPC1311/13/42/43 begin operation at power-up and when awakened from Deep
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.

7.18.5 Power control
The LPC1311/13/42/43 support a variety of power control features. There are three
special modes of processor power reduction: Sleep mode, Deep-sleep 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, a register is provided for 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. Selected peripherals have
their own clock divider which provides even better power control.
7.18.5.1
Power profiles (LPC1300L series, LPC1311/01 and LPC1313/01 only)
The power consumption in Active and Sleep modes can be optimized for the application
through simple calls to the power profile. The power configuration routine configures the
LPC1311/01 and the LPC1313/01 for one of the following power modes:
• Default mode corresponding to power configuration after reset.
• CPU performance mode corresponding to optimized processing capability.
• Efficiency mode corresponding to optimized balance of current consumption and CPU
performance.
• Low-current mode corresponding to lowest power consumption.
In addition, the power profile includes routines to select the optimal PLL settings for a
given system clock and PLL input clock.
7.18.5.2
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 but 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.
7.18.5.3
Deep-sleep mode
In Deep-sleep mode, the chip is in Sleep mode, and in addition all analog blocks are shut
down. As an exception, the user has the option to keep the watchdog oscillator and the
BOD circuit running for self-timed wake-up and BOD protection. Deep-sleep mode allows
for additional power savings.
Up to 40 pins total can serve as external wake-up pins to the start logic to wake up the
chip from Deep-sleep mode (see Section 7.19.1).
Unless the watchdog oscillator is selected to run in Deep-sleep mode, the clock source
should be switched to IRC before entering Deep-sleep mode, because the IRC can be
switched on and off glitch-free.

7.18.5.4
Deep power-down mode
In Deep power-down mode, power is shut off to the entire chip with the exception of the
WAKEUP pin. The LPC1311/13/42/43 can wake up from Deep power-down mode via the
WAKEUP pin.
A LOW-going pulse as short as 50 ns wakes up the part from Deep power-down mode.
When entering Deep power-down mode, an external pull-up resistor is required on the
WAKEUP pin to hold it HIGH. The RESET pin must also be held HIGH to prevent it from
floating while in Deep power-down mode.
7.19 System control
7.19.1 Start logic
The start logic connects external pins to corresponding interrupts in the NVIC. Each pin
shown in Table 3 and Table 4 as input to the start logic has an individual interrupt in the
NVIC interrupt vector table. The start logic pins can serve as external interrupt pins when
the chip is running. In addition, an input signal on the start logic pins can wake up the chip
from Deep-sleep mode when all clocks are shut down.
The start logic must be configured in the system configuration block and in the NVIC
before being used.
7.19.2 Reset
Reset has four sources on the LPC1311/13/42/43: the RESET pin, the Watchdog reset,
power-on reset (POR), and the Brown-Out 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 IRC and initializes the flash controller.
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.
7.19.3 Brownout detection
The LPC1311/13/42/43 includes four levels for monitoring the voltage on the VDD pin. If
this voltage falls below one of the four selected levels, the BOD asserts an interrupt signal
to the NVIC. 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. An additional threshold level can be selected to cause a
forced reset of the chip.
7.19.4 Code security (Code Read Protection - CRP)
This feature of the LPC1311/13/42/43 allows user to enable different levels of security in
the system so that access to the on-chip flash and use of the Serial Wire Debugger (SWD)
and In-System Programming (ISP) can be restricted. When needed, CRP is invoked by
programming a specific pattern into a dedicated flash location. In-Application
Programming (IAP) commands are not affected by the CRP.
In addition, ISP entry via the PIO0_1 pin can be disabled without enabling CRP (NO_ISP
mode). For details see the LPC13xx user manual.

LPC1311/13/42/43
NXP Semiconductors
32-bit ARM Cortex-M3 microcontroller
There are three levels of Code Read Protection:
1. CRP1 disables access to chip via the SWD 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.
2. CRP2 disables access to chip via the SWD and only allows full flash erase and
update using a reduced set of the ISP commands.
3. Running an application with level CRP3 selected fully disables any access to chip via
the SWD pins and the ISP. This mode effectively disables ISP override using PIO0_1
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
UART.
CAUTION
If level three Code Read Protection (CRP3) is selected, no future factory testing can be
performed on the device.
7.19.5 Boot loader
The boot loader controls initial operation after reset and also provides the means to
program the flash memory. This could be initial programming of a blank device, erasure
and re-programming of a previously programmed device, or programming of the flash
memory by the application program in a running system.
The boot loader code is executed every time the part is reset or powered up. The loader
can either execute the ISP command handler or the user application code, or, on the
LPC1342/43, it can program the flash image via an attached MSC device through USB
(Windows operating system only). A LOW level during reset applied to the PIO0_1 pin is
considered as an external hardware request to start the ISP command handler or the USB
device enumeration. The state of PIO0_3 determines whether the UART or USB interface
will be used (LPC1342/43 only).
7.19.6 APB interface
The APB peripherals are located on one APB bus.
7.19.7 AHB-Lite
The AHB-Lite connects the instruction (I-code) and data (D-code) CPU buses of the ARM
Cortex-M3 to the flash memory, the main static RAM, and the boot ROM.
7.19.8 External interrupt inputs
All GPIO pins can be level or edge sensitive interrupt inputs. In addition, start logic inputs
serve as external interrupts (see Section 7.19.1).
7.19.9 Memory mapping control
The Cortex-M3 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 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 8.
[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 8.
[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 8.
[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 8.
[7]
Tamb = 25 °C; maximum sampling frequency fs = 400 kSamples/s and analog input capacitance Cia = 1 pF.
[8]
Input resistance Ri depends on the sampling frequency fs: Ri = 1 / (fs × Cia).

9.5 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 SYSAHBCLKCFG or
PDRUNCFG (for analog blocks) registers. All other blocks are disabled in both registers
and no code is executed. Measured on a typical sample at Tamb = 25 °C. Unless noted
otherwise, the system oscillator and PLL are running in both measurements.
The supply currents are shown for system clock frequencies of 12 MHz, 48 MHz, and
72 MHz.

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.

The maximum tHD;DAT could be 3.45 μs and 0.9 μs 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.

11.2 XTAL input
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.

Fig 34. Slave mode operation of the on-chip oscillator
In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF
(Figure 34), 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 35 and in
Table 21 and Table 22. 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 35 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.

11.3 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 plain. 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. Values of Cx1 and Cx2 should be chosen smaller
accordingly to the increase in parasitics of the PCB layout.

11.6 ADC usage notes
The following guidelines show how to increase the performance of the ADC in a noisy
environment beyond the ADC specifications listed in Table 8:
• The ADC input trace must be short and as close as possible to the LPC1311/13/42/43
chip.
• The ADC input traces must be shielded from fast switching digital signals and noisy
power supply lines.
• Because the ADC and the digital core share the same power supply, the power supply
line must be adequately filtered.
• To improve the ADC performance in a very noisy environment, put the device in Sleep
mode during the ADC conversion.
