MAXQ610 19-4715 Rev 6 7/11 16-Bit Microcontroller with Infrared Module 16-Bit Instruction Word, 16-Bit Data Bus General Description 16 x 16-Bit General-Purpose Working Registers The MAXQ610 is a low-power, 16-bit MAXQ micro- controller designed for low-power applications includ- Secure MMU for Application Partitioning and IP ing universal remote controls, consumer electronics, Protection and white goods. The MAXQ610 combines a powerful Memory Features 16-bit RISC microcontroller and integrated peripherals including two USARTs and an SPI master/slave com- 64KB Flash: munications port, along with an IR module with carrier 512 Byte Sectors frequency generation and flexible port I/O capable of 20,000 Erase/Write Cycles per Sector multiplexed keypad control. Masked ROM Available The MAXQ610 includes 64KB of flash memory and 2KB 2KB Data SRAM of data SRAM. Intellectual property (IP) protection is Additional Peripherals provided by a secure MMU that supports multiple Power-Fail Warning application privilege levels and protects code against Power-On Reset/Brownout Reset copying and reverse engineering. Privilege levels Automatic IR Carrier Frequency Generation and enable vendors to provide libraries and applications to execute on the MAXQ610, while limiting access to only Modulation data and code allowed by their privilege level. Two 16-Bit, Programmable Timers/Counters with Prescaler and Capture/Compare For the ultimate in low-power battery-operated perfor- mance, the MAXQ610 includes an ultra-low-power stop SPI and Two USART Communication Ports mode (0.2A, typ). In this mode, the minimum amount Programmable Watchdog Timer of circuitry is powered. Wake-up sources include exter- 8kHz Nanopower Ring Oscillator Wake-Up Timer nal interrupts, the power-fail interrupt, and a timer inter- Up to 24 (MAXQ610A) or 32 (MAXQ610B) rupt. The microcontroller runs from a wide 1.70V to 3.6V General-Purpose I/Os operating voltage.
