Low-power 16-bit MCU

15 April 2009 DSP, Micros & Memory

The MAXQ610 is a low-power, 16-bit microcontroller (MCU) designed by Maxim for low-power applications including universal remote controls, consumer electronics and white goods. It combines a powerful 16-bit RISC microcontroller and integrated peripherals including two USARTs and an SPI master/slave communications port, along with an IR module with carrier frequency generation and flexible port I/O capable of multiplexed keypad control.

The MAXQ610 includes 64 KB of Flash memory and 2 KB of data SRAM. Intellectual property (IP) protection is provided by a secure MMU (memory management unit) that supports multiple application privilege levels and protects code against copying and reverse engineering. Privilege levels enable

vendors to provide libraries and applications to execute on the MCU, while limiting access to only data and code allowed by their privilege level.

For enhanced low-power battery-operated performance, the MAXQ610 includes an ultra low-power stop mode consuming just 0,2 μA. Wake-up sources include external interrupts, the power-fail interrupt and a timer interrupt. The microcontroller runs from a wide 1,7 V to 3,6 V operating voltage.
