The MAXQ611 is a low-power, 16-bit MAXQ® microcontroller designed for low-power applications including universal remote controls, consumer electronics, and white goods. The device combines a powerful 16-bit RISC microcontroller and integrated peripherals including two universal synchronous/asynchronous receiver-transmitters (USART), SPI master/slave and I2C communications ports, along with an IR module with carrier frequency generation and flexible port I/O capable of multiplexed keypad control.
The device provides 80KB of flash memory and 2KB of data SRAM.
For the ultimate in low-power battery-operated performance, the device includes an ultra-low-power stop mode. In this mode, the minimum amount of circuitry is powered. Wake-up sources include external interrupts, the power-fail interrupt, and a timer interrupt.
Applications
- Universal Remote Controls for Smartphones
- Universal Remote Controls for Tablets
