The MAXQ613 is a low-power, 16-bit MAXQ microcontroller designed for low-power applications including universal remote controls, consumer electronics, and white goods. The device combines a powerful 16-bit RISC microcontroller and integrated peripherals including a universal synchronous/asynchronous receiver-transmitter (USART) 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 device includes 48KB of flash program memory and 1.5KB of data SRAM. Intellectual property (IP) protection is provided by a secure 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 device, while limiting access to only data and code allowed by their privilege level. For the ultimate in low-power battery-operated performance, the device includes an ultra-low-power stop mode (0.2µA 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 wide 1.70V to 3.6V operating voltage. Designers must have the following documents to fully use all the features of this device. The data sheet contains pin descriptions, feature overviews, and electrical specifications. Errata sheets contain deviations from published specifications. The user"s guides offer detailed information about device features and operation.
