MC68340FT25E

The MC68340FT25E is a single-core 32-bit microprocessor module based on the CPU32 core, offered in a 144‑QFP (28×28) surface-mount package with 25 MHz operation and 5 V I/O. It integrates a CPU32 core and multiple on‑chip peripherals to address embedded control and general-purpose microprocessor-based systems.

Designed for embedded applications that benefit from high functional integration and efficient data movement, the MC68340FT25E combines processor performance with integrated DMA and peripheral subsystems to reduce board count and simplify system design.

Key Features

• CPU Core — CPU32, 32‑Bit: MC68020‑derived central processor with upward object‑code compatibility with MC68000/MC68010 and additional 32‑bit instructions and addressing modes.
• Clock Speed: 25 MHz core frequency as specified for this part number.
• Integrated DMA Controller: Two‑channel, low‑latency DMA supports single‑ or dual‑address transfers with 8‑, 16‑, and 32‑bit data sizes to accelerate high‑speed block transfers.
• Serial Interfaces — USART: Two‑channel universal synchronous/asynchronous receiver/transmitter functionality on‑chip for serial communications and modem control.
• Timers and Counters: Two independent 16‑bit counter/timer modules with up to 8‑bit prescaler and multimode operation for real‑time control and timing tasks.
• Memory and Bus: 32 address lines and 16 data lines with external bus interface and DRAM controller support for 16‑bit memory systems while delivering 32‑bit processor performance.
• System Integration Module: On‑chip functions for system configuration, chip select and wait‑state generation, interrupt response, bus arbitration, system protection, and IEEE 1149.1 boundary scan (JTAG).
• Power Management: Static HCMOS technology and on‑chip power controls including programmable clock throttling, peripheral power gating, and low‑power idle (LPSTOP) to reduce power in standby conditions.
• Package and Mounting: 144‑QFP (28×28) surface mount package, supplier package listed as 144‑BQFP.
• Operating Conditions: I/O voltage 5 V; specified operating temperature range 0 °C to 70 °C.
• Compliance: RoHS compliant.

Typical Applications

• Embedded Control Systems: On‑chip CPU32 core, timers, and integrated peripherals provide compact control functionality for embedded applications.
• High‑Throughput Data Transfer Systems: Two‑channel DMA supports high‑speed block transfers where rapid memory movement is required.
• General‑Purpose Microprocessor Systems: External bus interface and DRAM controller support make the device suitable for general computing tasks in space‑constrained designs.

Unique Advantages

• Highly Integrated Solution: Processor core, DMA, serial interfaces, timers, and system integration functions on a single IC reduce BOM and board space.
• Built‑In DMA for Efficient Data Movement: Two‑channel DMA offloads block transfers from the CPU, improving system throughput for data‑intensive operations.
• Established Code Compatibility: Object‑code compatibility with MC68000/MC68010 provides access to existing software, kernels, and development tools.
• Flexible Power Control: Programmable clock throttling, peripheral power gating, and LPSTOP idle state enable lower power consumption in standby and variable performance modes.
• System Integration Features: On‑chip system configuration, bus arbitration, chip select generation, and JTAG boundary scan simplify board‑level design and bring up.
• Industry‑Friendly Packaging and Compliance: Surface‑mount 144‑QFP package and RoHS compliance support standard assembly processes and regulatory requirements.
