MAXQ617:Infrared Remote Control System-on-Chip

Industry's Smallest UIR Solution with Dual I²C Interface

The MAXQ617 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 a universal synchronous/asynchronous receiver-transmitter (USART), an SPI master/slave and two I2C communications ports, along with an IR module with carrier frequency generation and flexible port I/O capable of multiplexed keypad control. An internal amplifier eliminates the need for external circuitry to drive the IR receiver pin. The device includes 80KB of flash memory and 4KB of data SRAM. For the ultimate in low-power battery-operated performance, the device 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 1.67V to 3.6V operating voltage.
