The ML670100 is a high-performance 32-bit microcontroller combining a RISC based, 32-bit CPU core - the ARM7TDMITM - with memory and such peripheral circuits as timers, serial ports, and analog-todigital converter. This combination of 32-bit data processing, built-in memory, and on-chip peripherals make it ideal for controlling equipment requiring both high speed and high functionality. An external memory controller ML670100 supports direct connection to memory and peripheral devices for adding even more functionality.
