General Description

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.
