MAXQ61H

19-4604; Rev 3; 3/12 MAXQ61H 16-Bit Microcontroller with Infrared Module General Description The MAXQ61H is a low-power, 16-bit MAXQ® microcontroller designed for low-power applications including 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 generation 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 performance, 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 external interrupts, the power-fail interrupt, and a timer interrupt. The microcontroller runs from a wide 1.70V to 3.6V operating voltage.
