Product data sheet
1. General description
The LPC83x are an ARM Cortex-M0+ based, low-cost 32-bit MCU family operating at
CPU frequencies of up to 30 MHz. The LPC83x support up to 32 KB of flash memory and
4 KB of SRAM.
The peripheral complement of the LPC83x includes a CRC engine, one I2C-bus interface,
one USART, up to two SPI interfaces, one multi-rate timer, self-wake-up timer, and
SCTimer/PWM, a DMA, one 12-bit ADC, function-configurable I/O ports through a switch
matrix, an input pattern match engine, and up to 29 general-purpose I/O pins.
For additional documentation related to the LPC83x parts, see Section 18.
2. 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.
Macro Trace Buffer (MTB).
Memory:
Up to 32 KB on-chip flash programming memory with 64 Byte page write and
erase. Code Read Protection (CRP) supported.
4 KB SRAM.
ROM API support:
Boot loader.
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.

LPC83x
32-bit ARM Cortex-M0+ microcontroller
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 8 trigger inputs.
Timers:
SCTimer/PWM with up to 4 capture inputs and 4 match output functions for timing
and PWM applications.
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.
Serial peripherals:
One USART interface with pin functions assigned through the switch matrix and
one fractional baud rate generator.
Two SPI controllers with pin functions assigned through the switch matrix.
One I2C-bus interface. Supports Fast-mode Plus with 1 Mbit/s data rates on the
open-drain pins and listen mode.
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).
