The MAXQ615 is a low-power, 16-bit MAXQ microcontroller designed for low-power applications. The device combines a powerful 16-bit RISC microcontroller and integrated peripherals including multiple high-speed serial communication interfaces and flexible port I/O. High-speed communication interfaces include dual SPI and I²C. The device also provides three instances of the 16-bit timer B peripheral. A 16 x 16 hardware multiply/accumulate with 48-bit accumulator provides support for computationally intensive applications. The device provides 48KB of flash memory and 2KB of data SRAM. For the ultimate in low-power 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 single 2.4V to 3.6V power-supply operating voltage.
