16-Bit Microcontroller with Infrared Module

19-5231; Rev 0; 4/10

Ordering Information/Selector Guide

General Description

controller designed for low-power applications including

universal remote controls, consumer electronics, and

white goods. The device combines a powerful 16-bit

RISC microcontroller and integrated peripherals includ-

ing two universal synchronous/asynchronous receiver-

transmitters (USARTs) and an SPI™ master/slave com-

munications port, along with an IR module with carrier

frequency generation and flexible port I/O capable of

multiplexed keypad control.

The device includes 80KB of ROM memory and 2KB of

data SRAM.

For the ultimate in low-power battery-operated perfor-

mance, the device includes an ultra-low-power stop

mode (0.2µA typ). In this mode, the minimum amount of

circuitry is powered. Wake-up sources include external

interrupts, the power-fail interrupt, and a timer interrupt.

The microcontroller runs from a wide 1.70V to 3.6V oper-

ating voltage.
