Product Details
The MAXQ612/MAXQ622 are low-power, 16-bit MAXQ® microcontrollers designed for low-power applications including universal remote controls, consumer electronics, and white goods. Both devices use a low-power, high-throughput, 16-bit RISC microcontroller. Serial peripherals include two universal synchronous/asynchronous receiver-transmitters (USARTs), two SPI™ master/slave communications ports, and an inter-integrated circuit (I²C) bus. The devices also incorporate an IR module with carrier frequency generation and flexible port I/O capable of multiplexed keypad control. The MAXQ622 adds a universal serial bus (USB) with integrated physical interface (PHY).
The MAXQ612/MAXQ622 include 128KB of flash memory and 6KB of data SRAM. Intellectual property (IP) protection is provided by a secure memory management unit (MMU) 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 MAXQ612/MAXQ622, while limiting access to only data and code allowed by their privilege level.
For the ultimate in low-power battery-operated performance, the devices include an ultra-low-power stop mode (0.3µA typical). 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 wide operating voltage of 1.70V to 3.6V, and can also be powered from the USB.
