MAXQ611

Infrared Remote Control System-On-Chip

General Description

The MAXQ611 is a low-power, 16-bit MAXQ® microcontroller 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 including a
universal synchronous/asynchronous receiver-transmitter
(USART), SPI master/slave and I2C communications
ports, along with an IR module with carrier frequency
generation and flexible port I/O capable of multiplexed
keypad control. An internal amplifier eliminates the need
for external circuitry to drive the IR receiver pin.
The device provides 80KB of flash memory and 2KB of
data SRAM.
For the ultimate in low-power battery-operated performance, the device includes an ultra-low-power stop mode.
In this mode, the minimum amount of circuitry is powered.
Wake-up sources include external interrupts, the power-fail
interrupt, and a timer interrupt.

Applications

●● Universal Remote Controls for Tablets
●● Universal Remote Controls for Smartphones
