SEMICONDUCTOR PRODUCT INFORMATION
The MMC2001 microcontroller is the first member of the MCORE family of single-chip control systems. The
MCORE architecture is targeted for high-performance and cost-sensitive embedded control applications, with
particular emphasis on reduced system power consumption, making the MMC2001 suitable for battery-operat-
ed products.
The MMC2001 incorporates the following functional units:
MCORE Integer Processor
—
32-bit RISC architecture, 16-bit instructions
—
Low power, high performance
OnCE Debug Module
On-chip SRAM, 32 kbytes with battery backup supply support
On-Chip ROM, 256 kbytes
Interrupt Controller with support for up to 32 Interrupt sources
External Interface Module
—
External interface with 20 address lines and 16 data lines
—
Chip select and wait state generation
—
Bus watchdog timer
Timer/Reset Module
—
Crystal oscillator generates on-chip clock signal from a 32.768 kHz crystal
—
Time-of-day timer provides real-time event information
—
Watchdog timer resets the chip to recover from system failure
—
Reset unit provides low voltage detection and backup power switching
—
Periodic interrupt timer
Serial Communication Port (UART)
—
Two independent UART channels
—
Asynchronous Operation
—
Baud Rate Generation
16-bit General Purpose I/O Port with support for Keyboard Scan / Encode
