The MAXQ615 is a low-power, 16-bit MAXQM microcontrollerdesigned for low-power applications. The devicecombines a powerful 16-bit RISC microcontroller andintegrated peripherals including multiple high-speedserial communication interfaces and flexible port I/O.High-speed communication interfaces include dual SPIand 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 supportfor computationally intensive applications. The deviceprovides 48KB of flash memory and 2KB of data SRAM.For the ultimate in low-power performance, the deviceincludes an ultra-low-power stop mode (0.2FA typ). Inthis mode, the minimum amount of circuitry is powered.Wake-up sources include external interrupts, the powerfailinterrupt, and a timer interrupt. The microcontrollerruns from a single 2.4V to 3.6V power-supply operatingvoltage.
