MAXQ614
16-Bit Microcontroller with Infrared Module
General Description
The MAXQ614 is a low-power, 16-bit MAXQ^® microcon-
troller 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) along with an IR module with car-
rier frequency generation and flexible port I/O capable of
multiplexed keypad control.
The device includes 80KB of flash 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 micro-
controller runs from a wide 1.70V to 3.6V operating voltage.
