MC68340CFE16E

The MC68340CFE16E is a high-functionality, single-core CPU32 microprocessor in a 144‑CQFP surface-mount package. It combines a 32‑bit CPU32 core running at 16 MHz with integrated peripheral subsystems and a two‑channel DMA controller for embedded control and general computing applications.

Designed for systems that benefit from on‑chip integration, the MC68340CFE16E delivers tightly integrated DMA, serial interfaces, timers and system integration features to reduce component count, board space and power consumption while easing system design and manufacturing.

Key Features

• Core — CPU32 32‑bit central processor, 1 core, 16 MHz operation; MC68020‑derived core with upward object‑code compatibility to MC68000 and MC68010.
• Direct Memory Access (DMA) — Two‑channel low‑latency DMA controller with 32‑bit addresses and counters; supports 8‑, 16‑ and 32‑bit data transfers and sustained transfers up to 50 Mbyte/s (12.5 Mbyte/s memory‑to‑memory).
• Serial Interfaces — Two‑channel USART implementation with baud rate generators and modem control; MC68681/MC2681 compatible and up to 9.8 Mbits/s maximum transfer rate.
• Timers and Counters — Two independent 16‑bit counter/timers with up to 8‑bit prescaler and multimode operation providing fine timing resolution.
• System Integration Module — On‑chip functions for external bus interface, chip select and wait‑state generation, bus arbitration, system protection, periodic interrupt timer and IEEE 1149.1 boundary scan (JTAG).
• Memory and Bus — 32 address lines and 16 data lines with DRAM controller support for conventional embedded memory configurations.
• Power and Packaging — 5 V I/O voltage; 144‑CQFP package (26.77×26.77 mm); surface‑mount mounting type; RoHS compliant.
• Environmental — Industrial operating temperature range from −40 °C to 85 °C.

Typical Applications

• Embedded Control — Integrated CPU and peripheral set support control tasks where reduced BOM and tight integration speed development.
• General Computing — 32‑bit processing and MC68000/MC68010 code compatibility enable use in legacy‑aware computing systems.
• High‑Speed Data Transfer — Two‑channel DMA and high sustained throughput accelerate block memory transfers and data movement tasks.
• Industrial Systems — Industrial temperature rating and surface‑mount 144‑CQFP package make it suitable for ruggedized embedded applications.

Unique Advantages

• Highly integrated single‑chip solution: CPU32 core, DMA, USARTs, timers and system integration functions reduce external components and PCB complexity.
• High‑throughput DMA: Two DMA channels with 32‑bit addressing and multi‑width transfers enable efficient, low‑CPU‑overhead block moves.
• Legacy software leverage: Upward object‑code compatibility with MC68000/MC68010 allows reuse of established real‑time kernels, operating systems and development tools.
• Design for manufacturing: IEEE 1149.1 boundary scan (JTAG) in the system integration module supports test and debug flows.
• Industrial readiness: −40 °C to 85 °C operating range and RoHS compliance address industrial deployment requirements.
• Compact, surface‑mount packaging: 144‑CQFP (26.77×26.77 mm) supports dense PCB layouts and standard SMT assembly.
