16-Bit MAXQ Microcontroller with
The MAXQ615 is a low-power, 16-bit MAXQM microcon-
troller 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 (0.2FA 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
