The MAXQ612/MAXQ622 are low-power, 16-bit MAXQ

microcontrollers designed for low-power applications

including universal remote controls, consumer elec-

tronics, and white goods. Both devices use a low-

power, high-throughput, 16-bit RISC microcontroller.

Serial peripherals include two universal synchronous/

asynchronous receiver-transmitters (USARTs), two SPIK

master/slave communications ports, and an inter-inte-

grated circuit (I

an IR module with carrier frequency generation and

flexible port I/O capable of multiplexed keypad control.

The MAXQ622 adds a universal serial bus (USB) with

integrated physical interface (PHY).

The MAXQ612/MAXQ622 include 128KB of flash memory

and 6KB of data SRAM. Intellectual property (IP) protection is

provided by a secure memory management unit (MMU) that

supports multiple application privilege levels and protects

code against copying and reverse engineering. Privilege

levels enable vendors to provide libraries and applications to

execute on the MAXQ612/MAXQ622, while limiting access

to only data and code allowed by their privilege level.

For the ultimate in low-power battery-operated perfor-

mance, the devices include an ultra-low-power stop mode

(0.3FA typical). 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 operating voltage of

1.70V to 3.6V, and can also be powered from the USB.
