MC68EC030FE25C

The MC68EC030FE25C from NXP Semiconductors is a second-generation 32-bit enhanced embedded controller. It streamlines the functionality of an MC68030 for embedded control applications, optimized for performance with cost-effective memory subsystems. This microprocessor maintains the rich instruction set and addressing modes of the M68000 family, allowing for a clear migration path.

Key features include a 25MHz operating frequency, a 32-bit, 1-core architecture, and a 5.0V operating voltage. It incorporates on-chip data and instruction caches, each 256 Bytes in size, and supports dynamic bus sizing for direct interface to 8-, 16-, and 32-bit devices. The device offers a 4-Gbyte direct addressing range.

Packaged in a 132-CQFP (24x24) format, the MC68EC030FE25C is designed for surface mounting. Its advanced Plastic Pin Grid Array packaging is suitable for through-hole applications. The controller is implemented using Motorola's HCMOS technology, combining CMOS and HMOS gates for maximum speed, low power consumption, and small die size.

This embedded controller is object-code compatible with earlier M68000 microprocessors and features a burst-mode bus interface for efficient DRAM access. It also supports coprocessors via the M68000 Coprocessor Interface and has an enhanced bus controller supporting asynchronous, synchronous, and burst data transfers.
