LPC81xM

32-bit ARM Cortex-M0+ microcontroller

 Multiple-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 or a low-power,

low-frequency internal oscillator.

 CRC engine.

 Windowed Watchdog timer (WWDT).

 Analog peripherals:

 Comparator with external voltage reference with pin functions assigned or enabled

through the switch matrix.

 Serial interfaces:

 Three USART interfaces with pin functions assigned through the switch matrix.

 Two SPI controllers with pin functions assigned through the switch matrix.

 One I2C-bus interface with pin functions assigned through the switch matrix.

 Clock generation:

 12 MHz internal RC oscillator trimmed to 1 % 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.

 10 kHz low-power oscillator for the WKT.

 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 CLKIN, or the internal RC oscillator.

 Clock output function with divider that can reflect the crystal oscillator, the main

clock, the IRC, or the watchdog oscillator.

 Power control:

 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.

 Power-On Reset (POR).

 Brownout detect.

 Unique device serial number for identification.

 Single power supply.

 Available as SO20 package, TSSOP20 package, TSSOP16, and DIP8 package.

Applications

 8/16-bit applications

 Lighting

 Consumer

 Motor control

 Climate control

 Fire and security applications
