MAXQ615

16-Bit MAXQ Microcontroller with

Hardware Multiplier

General Description

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

voltage.
