The MAXQ610 is a low-power, 16-bit MAXQ

controller designed for low-power applications includ-

ing universal remote controls, consumer electronics,

and white goods. The MAXQ610 combines a powerful

16-bit RISC microcontroller and integrated peripherals

including two USARTs and an SPI™ master/slave com-

munications port, along with an IR module with carrier

frequency generation and flexible port I/O capable of

multiplexed keypad control.

The MAXQ610 includes 64KB of flash memory and 2KB

of data SRAM. Intellectual property (IP) protection is

provided by a secure 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 MAXQ610, while limiting access to only

data and code allowed by their privilege level.

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

mance, the MAXQ610 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.

♦ High-Performance, Low-Power 16-Bit RISC Core

♦ DC to 12MHz Operation Across Entire Operating

♦ 1.70V to 3.6V Operating Voltage Range

♦ 33 Total Instructions for Simplified Programming

♦ Three Independent Data Pointers Accelerate Data
