MC68340PV16E

The MC68340PV16E is a CPU32-based 32-bit microprocessor IC featuring an integrated peripheral set and on-chip DMA, delivered in a 144-LQFP (20×20) surface-mount package. With a 16 MHz operating clock and 5 V I/O, it targets embedded control and general microprocessor-based systems that benefit from high functional integration and on-chip data-movement hardware.

Designed to reduce board-level component count and simplify system design, the MC68340 series combines a 32-bit core, DMA controller, USARTs and system integration functions to lower power, board space and overall system cost while improving reliability and design time.

Key Features

• Core Processor (CPU32)  32-bit CPU32 core derived from the MC68020 family with upward object-code compatibility with MC68000/MC68010 and additional 32-bit instructions and addressing modes.
• Integrated Two-Channel DMA  Two-channel low-latency DMA supporting 32-bit addresses and counters with 8-/16-/32-bit transfers for high-speed block memory moves.
• Serial Interfaces  Two-channel USARTs with baud rate generators and modem control; series-level maximum transfer capability documented in the product literature.
• Timers and Counters  Two independent 16-bit counters with up to 8-bit prescaler and multimode operation providing fine timing control (80 ns resolution noted in series documentation).
• System Integration Module  On-chip system functions including external bus interface, chip-select and wait-state generation, interrupt response, bus arbitration, configuration, and power-on reset to simplify external logic.
• Memory and Bus  32 address lines and 16 data lines with DRAM controller support to interface with common memory subsystems.
• Power and Mounting  5 V I/O voltage, surface-mount 144-LQFP (20×20) package, and power-management features in the series such as programmable clock throttling and peripheral shutdown modes.
• Operating Range and Compliance  Operating temperature range 0 °C to 70 °C and RoHS compliance for environmental conformity.

Typical Applications

• Embedded Control Systems  Use as the main controller for embedded applications where integrated timers, DMA and serial interfaces simplify real-time control and I/O handling.
• General Microprocessor-Based Equipment  Suitable for compact systems requiring a single-chip solution with an integrated bus interface and peripheral set to reduce external logic.
• High-Speed Block Data Transfer  Systems that need efficient memory-to-device or memory-to-memory block transfers can leverage the on-chip DMA channels for sustained data movement.
• Legacy Code and Toolchain Reuse  Designs that benefit from compatibility with MC68000 family code and existing embedded kernels, operating systems and development tools.

Unique Advantages

• Highly Integrated Solution: On-chip CPU, DMA, USARTs and system integration reduce BOM and board area while simplifying routing and component selection.
• Efficient Block Transfers: Two-channel DMA with 32-bit addressing enables sustained high-throughput transfers to accelerate data movement tasks.
• Compatibility with Established Ecosystem: Object-code compatibility with MC68000/MC68010 allows reuse of existing codebases, real-time kernels and development tools.
• Flexible System Control: Integrated system functions (bus arbitration, chip selects, wait-state generation, power-on reset) reduce external glue logic and streamline board design.
• Compact Surface-Mount Package: 144-LQFP (20×20) delivers a dense, surface-mount footprint suitable for space-constrained designs.
• Regulatory and Environmental: RoHS compliance supports environmentally conscious design and manufacturing requirements.
