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.
