MAXQ610 具有红外功能的16位微控制器

MAXQ610概述

The MAXQ610 is a low-power, 16-bit MAXQ® microcontroller designed for low-power applications including 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 communications 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 performance, 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 external interrupts, the power-fail interrupt, and a timer interrupt. The microcontroller runs from a wide 1.70V to 3.6V operating voltage.
