16-Bit Microcontroller with Infrared Module
General Description
The MAXQ61H is a low-power, 16-bit MAXQ^® micro-
controller designed for low-power applications includ-
ing universal remote controls, consumer electronics,
and white goods. The MAXQ61H combines a powerful
16-bit RISC microcontroller and integrated peripherals
including an IR module with carrier frequency genera-
tion and flexible port I/O capable of multiplexed keypad
control.
The MAXQ61H includes 36KB of ROM memory and
1.28KB of data SRAM.
For the ultimate in low-power battery-operated perfor-
mance, the MAXQ61H includes an ultra-low-power stop
mode (0.2µA, typ). In this mode, the minimum amount
of circuitry is powered. Wake-up sources include exter-
nal interrupts, the power-fail interrupt, and a timer inter-
rupt. The microcontroller runs from a wide 1.70V to 3.6V
operating voltage.
