MC68340CAG25E

The MC68340CAG25E is a CPU32-based 32-bit microprocessor in a 144-LQFP (20×20) surface-mount package with a 25 MHz core clock. Designed for embedded and industrial applications, the device integrates core processing, memory controller support and peripheral modules to support compact, system-level designs.

With a single CPU32 core, DRAM controller capability, on-chip serial interfaces and documented integrated DMA and timer modules, the MC68340CAG25E targets embedded systems that require deterministic control, serial communications and board-level integration across an industrial temperature range.

Key Features

• CPU Core — Single CPU32 32-bit core operating at 25 MHz for deterministic embedded processing.
• Memory Interface — DRAM controller support to interface with external dynamic RAM for application data buffering and code storage.
• Integrated DMA and Timers — On-chip DMA controller and timer modules (as referenced in the MC68340 documentation) enable efficient data movement and scheduling without continuous CPU intervention.
• Serial Communication — USART interface for standard serial data connectivity and peripheral communication.
• System Integration & Test — System integration module and IEEE 1149.1 test access support are documented for board-level integration and boundary-scan testing.
• Package & Mounting — 144-LQFP (20×20) surface-mount package for compact PCB layouts and high-density designs.
• Operating Conditions — Industrial qualification with an operating temperature range of −40°C to 85°C and 5 V I/O support.

Typical Applications

• Embedded Industrial Control — Use in industrial embedded systems that require a 32-bit processor with DRAM interface and deterministic timing across −40°C to 85°C.
• Communications Equipment — Serial interfacing via USART and DMA support for efficient data transfer in communications and telemetry modules.
