MC68302CEH16C

The MC68302CEH16C from NXP Semiconductors is a versatile one-chip processor designed for networking and communications products. It integrates an MC68000/MC68008 microprocessor core, a system integration block, and a communications processor.

This microprocessor operates at a speed of 16MHz and requires a 5.0V supply voltage. It features an operating temperature range of -40°C to 85°C. The device includes three Serial Communications Controllers (SCCs) supporting various protocols like HDLC/SDLC, Bisync, UART, DDCMP, and Totally Transparent. It also has two Serial Management Controllers (SMCs) for IDL and GCI channels.

The MC68302CEH16C is housed in a 132-PQFP (46x46) package and is suitable for surface mounting. It offers features such as an Independent Direct Memory Access (IDMA) Controller, an interrupt controller, parallel I/O ports, on-chip dual-port RAM, and multiple timers. The processor also supports DRAM controllers and has bus arbitration logic with low interrupt latency.

Typical applications for this processor include ISDN equipment, data concentrators, modems, line cards, network bridges, and gateways. Its flexible architecture allows for concurrent operation of different protocols, making it a suitable choice for complex communication systems.
