Key Features

• CPU32 32-bit Core — Single 32-bit CPU32 core providing 32-bit instruction execution and CISC architecture.
• 25 MHz Operating Speed — Processor clocked at 25 MHz suitable for embedded control tasks and real-time processing.
• Integrated DMA Controller — On-chip DMA (two-channel as described in the MC68340 family) for high-speed block transfers with 32-bit addressing and support for 8-, 16- and 32-bit data transfers.
• Serial Interfaces (USART) — Integrated serial communications with multi-channel USART capability for asynchronous/synchronous links (family datasheet lists two-channel USART functionality and high transfer rate support).
• Memory and DRAM Controller — On-chip DRAM controller to manage external dynamic memory interfaces and simplify system memory design.
• Timers and System Integration — Multiple timers and a system integration module providing chip select, wait-state generation, interrupt response and other system functions (as described for the MC68340 family).
• I/O and Bus — 32 address lines and 16 data lines (family-level specification) to interface with external memory and peripherals.
• Industrial Qualification and Temperature Range — Rated for industrial operation from −40 °C to 85 °C.
• Package and Mounting — 144-CQFP surface-mount package (144-BCQFP / 144-CQFP 26.77×26.77) for compact board layouts.
• Electrical — 5 V I/O voltage domain supporting legacy voltage environments.
• Compliance — RoHS compliant.

Typical Applications

• Embedded Control — Use as the main controller in industrial control systems where integrated DMA and timers accelerate real-time tasks and peripheral coordination.
• Communications Interfaces — Leverage the on-chip USART channels for modem and serial link handling in instrumentation and data-acquisition systems.
• Memory-Intensive Operations — Employ the DMA and DRAM controller for applications requiring high-speed block transfers and external memory management.
• General-Purpose Embedded Systems — Suitable for compact, board-level systems that benefit from on-chip system integration to reduce BOM and PCB area.

Unique Advantages

• Highly Integrated Architecture: Combines CPU, DMA, serial I/O, timers and system integration functions on a single chip to lower component count and simplify system design.
• On-Chip DMA for Efficient Data Movement: Two-channel DMA with 32-bit addressing enables high-speed block transfers without burdening the CPU, improving overall system throughput.
• Industrial Temperature Qualification: Specified operation from −40 °C to 85 °C for deployment in demanding environments.
• Legacy Voltage Support: 5 V I/O compatibility eases integration into existing systems with established voltage domains.
• Compact Surface-Mount Package: 144-CQFP footprint (26.77×26.77) provides a balance of pin count and PCB area for space-constrained designs.
• Standards and Tooling Compatibility: Family-level code compatibility with established MC68000-series tools and software ecosystems is documented for MC68340 devices.
