MAXQ615 16-Bit MAXQ Microcontroller with Hardware Multiplier General Description Features M The MAXQ615 is a low-power, 16-bit MAXQ microcon- S Core Functionality troller designed for low-power applications. The device High-Performance, Low-Power 16-Bit MAXQ20S combines a powerful 16-bit RISC microcontroller and RISC Core integrated peripherals including multiple high-speed DC to 20MHz Operation Across Entire serial communication interfaces and flexible port I/O. Operating Range High-speed communication interfaces include dual SPI 2.4V to 3.6V Operating Voltage 2 and I C. The device also provides three instances of the Three Independent Data Pointers Accelerate 16-bit timer B peripheral. A 16 x 16 hardware multiply/ Data Movement with Automatic Inc/Dec accumulate with 48-bit accumulator provides support Dedicated Pointer for Direct Read from Code for computationally intensive applications. The device Space provides 48KB of flash memory and 2KB of data SRAM. 16-Bit Instruction Word, 16-Bit Data Bus For the ultimate in low-power performance, the device 16 x 16-Bit General-Purpose Working Registers includes an ultra-low-power stop mode (0.2FA typ). In Optimized for C Compiler this mode, the minimum amount of circuitry is powered. S Memory Wake-up sources include external interrupts, the power- 48KB Flash Memory fail interrupt, and a timer interrupt. The microcontroller 1KB Page Sectors runs from a single 2.4V to 3.6V power-supply operating 20,000 Erase/Write Cycles per Sector voltage. 2KB Data SRAM Masked ROM Available Applications S I/O and Peripherals Power-Fail Warning Portable Computing Power-On Reset/Brownout Reset Battery-Powered Portable Equipment Three 16-Bit Programmable Timers/Counters Consumer Electronics with Prescaler Home Appliances Programmable Watchdog Timer Internal 20MHz Clock 5% White Goods Dual SPI Ports with 16-Byte FIFO 2 I C Communication Port Up to 12 General-Purpose I/O Pins S Low Power Consumption 0.2A (typ) in Stop Mode 2.6mA (typ) at 20MHz Divided System Clock Modes Available Ordering Information appears at end of data sheet.
