16-Bit Microcontroller with Infrared Module
General Description
The MAXQ610 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 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.
