MC68340FE16VE

The MC68340FE16VE is a CPU32-based 32-bit microprocessor in a 144-pin CQFP package, operating at 16 MHz with 3.3 V I/O. It integrates a CPU32 core with on-chip peripherals and a DMA controller to support embedded control and general computing applications that require efficient block data movement and system-level integration.

Designed for surface-mount PCB assemblies, the device targets embedded systems that benefit from high functional integration and accessible development ecosystems compatible with existing MC68000 family code and tools.

Key Features

• CPU Core  CPU32 core delivering 32-bit processor functionality with upward object-code compatibility with MC68000/MC68010 and additional MC68020-derived instructions.
• Clock and Voltage  16 MHz operating speed with 3.3 V I/O voltage.
• Integrated DMA  Two-channel, low-latency DMA controller supporting single- or dual‑address transfers, 32-bit addresses and counters, and 8/16/32-bit data transfers for high-speed block moves.
• Serial Interfaces  Two-channel USART with baud rate generators and modem control capability; compatible feature set referenced in the product brief.
• Timers and Counters  Two independent 16-bit counter/timers with up to 8-bit prescaler and multimode operation for event timing and scheduling.
• Memory and Bus  External bus interface with 32 address lines and 16 data lines and integrated DRAM controller support.
• System Integration Module  On-chip subsystem for system configuration, bus arbitration, chip select and wait-state generation, periodic interrupt timer, dynamic bus sizing and system protection features.
• Debug and Test  IEEE 1149.1 boundary-scan (JTAG) support for board-level testability.
• Package and Mounting  144‑CQFP surface-mount package (26.77 × 26.77 mm) suitable for compact embedded designs.
• Operating Range  Specified for operation from 0 °C to 70 °C.
• Environmental Compliance  RoHS compliant.

Typical Applications

• Embedded Control  Suited for embedded control systems that require a 32-bit CPU with integrated peripherals and timing resources.
• General Computing  Appropriate for compact general-purpose microprocessor-based systems that benefit from MC68000-family code compatibility.
• Data Transfer–Intensive Systems  Systems requiring high-speed block transfers can leverage the two-channel DMA for efficient memory-to-memory and peripheral transfers.

Unique Advantages

• Highly integrated processor plus peripherals: Combines a CPU32 core, DMA controller, USARTs, timers and system integration functions on a single IC to reduce component count and board complexity.
• DMA-driven throughput: Two-channel DMA with 32-bit addressing and support for multiple data widths enables sustained high-speed block transfers for data-heavy tasks.
• MC68000-family code compatibility: Upward object-code compatibility with MC68000/MC68010 gives access to an established software and tools ecosystem.
• Board-level test and protection: IEEE 1149.1 boundary-scan plus on-chip system protection and configuration features simplify testing and system reliability measures.
• Low-voltage operation: 3.3 V I/O supports designs with tight power budgets while remaining RoHS compliant.
