General description
The LPC82x are an ARM Cortex-M0+ based, low-cost 32-bit MCU family operating at
CPU frequencies of up to 30 MHz. The LPC82x support up to 32 KB of flash memory and
8 KB of SRAM.
The peripheral complement of the LPC82x includes a CRC engine, four I2C-bus
interfaces, up to three USARTs, up to two SPI interfaces, one multi-rate timer,
self-wake-up timer, and state-configurable timer with PWM function (SCTimer/PWM), a
DMA, one 12-bit ADC and one analog comparator, function-configurable I/O ports through
a switch matrix, an input pattern match engine, and up to 29 general-purpose I/O pins.

Features and benefits
 System:
 ARM Cortex-M0+ processor (revision r0p1), running at frequencies of up to
30 MHz with single-cycle multiplier and fast single-cycle I/O port.
 ARM Cortex-M0+ built-in Nested Vectored Interrupt Controller (NVIC).
 System tick timer.
 AHB multilayer matrix.
 Serial Wire Debug (SWD) with four break points and two watch points. JTAG
boundary scan (BSDL) supported.
 MTB
 Memory:
 Up to 32 KB on-chip flash programming memory with 64 Byte page write and
erase. Code Read Protection (CRP) supported.
 8 KB SRAM.
 ROM API support:
 Boot loader.
 On-chip ROM APIs for ADC, SPI, I2C, USART, power configuration (power
profiles) and integer divide.
 Flash In-Application Programming (IAP) and In-System Programming (ISP).
 Digital peripherals:
 High-speed GPIO interface connected to the ARM Cortex-M0+ IO bus with up to 29
General-Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors,
programmable open-drain mode, input inverter, and digital filter. GPIO direction
control supports independent set/clear/toggle of individual bits.
 High-current source output driver (20 mA) on four pins.
 High-current sink driver (20 mA) on two true open-drain pins.
 GPIO interrupt generation capability with boolean pattern-matching feature on eight
GPIO inputs.
 Switch matrix for flexible configuration of each I/O pin function.
 CRC engine.
 DMA with 18 channels and 9 trigger inputs.
 Timers:
 State Configurable Timer (SCTimer/PWM) with input and output functions
(including capture and match) for timing and PWM applications. Each
SCTimer/PWM input is multiplexed to allow selecting from several input sources
such as pins, ADC interrupt, or comparator output.
 Four channel Multi-Rate Timer (MRT) for repetitive interrupt generation at up to
four programmable, fixed rates.
 Self-Wake-up Timer (WKT) clocked from either the IRC, a low-power,
low-frequency internal oscillator, or an external clock input in the always-on power
domain.
 Windowed Watchdog timer (WWDT).
 Analog peripherals:
 One 12-bit ADC with up to 12 input channels with multiple internal and external
trigger inputs and with sample rates of up to 1.2 Msamples/s. The ADC supports
two independent conversion sequences.
 Comparator with four input pins and external or internal reference voltage.
 Serial peripherals:
 Three USART interfaces with pin functions assigned through the switch matrix and
one common fractional baud rate generator.
 Two SPI controllers with pin functions assigned through the switch matrix.
 Four I2C-bus interfaces. One I2C supports Fast-mode Plus with 1 Mbit/s data rates
on two true open-drain pins and listen mode. Three I2Cs support data rates up to
400 kbit/s on standard digital pins.
 Clock generation:
 12 MHz internal RC oscillator trimmed to 1.5 % accuracy that can optionally be
used as a system clock.
 Crystal oscillator with an operating range of 1 MHz to 25 MHz.
 Programmable watchdog oscillator with a frequency range of 9.4 kHz to 2.3 MHz.
 PLL allows CPU operation up to the maximum CPU rate without the need for a
high-frequency crystal. May be run from the system oscillator, the external clock
input, or the internal RC oscillator.
 Clock output function with divider that can reflect all internal clock sources.
 Power control:
 Power consumption in active mode as low as 90 uA/MHz in low-current mode
using the IRC as the clock source.
 Integrated PMU (Power Management Unit) to minimize power consumption.
 Reduced power modes: Sleep mode, Deep-sleep mode, Power-down mode, and
Deep power-down mode.
 Wake-up from Deep-sleep and Power-down modes on activity on USART, SPI, and
I2C peripherals.
 Timer-controlled self wake-up from Deep power-down mode.
 Power-On Reset (POR).
 Brownout detect (BOD).
 Unique device serial number for identification.
 Single power supply (1.8 V to 3.6 V).
 Operating temperature range -40 °C to +105 °C.
 Available in a TSSOP20 and HVQFN33 (5x5) package.
