MC68340FT16E

The MC68340FT16E is a CPU32-based 32-bit microprocessor IC with a 16 MHz clock and a single-core architecture in a 144-pin QFP (28×28 mm) surface-mount package. It integrates a CPU32 core together with DMA and peripheral subsystems to address embedded control and general computing applications where integrated I/O, timers, and high-speed block transfers are required.

Designed for embedded systems, the device delivers a compact, highly integrated solution that reduces component count and board space while providing on-chip peripherals and system integration functions documented for the MC68340 series.

Key Features

• CPU32 Core (32‑bit)  The part implements the CPU32 central processor core derived from the MC68020 family, providing 32‑bit operation in a single-core configuration.
• 16 MHz Clock Speed  Standard operating frequency of 16 MHz for timing and processing as specified for this part number.
• On‑chip DMA  Series documentation notes a two‑channel DMA controller capable of high‑speed block transfers, supporting single- or dual‑address transfers with 8‑, 16‑, and 32‑bit data widths.
• Serial Interfaces  Includes USART functionality (two‑channel USART described for the series) for synchronous/asynchronous serial communications and modem control features.
• Memory and Bus  Supports a DRAM controller and a 32‑bit address bus with 16 data lines to interface with external memory and peripherals.
• Timers and Counters  Series information describes two independent counter/timer modules with 16‑bit counters and multimode operation for event timing and scheduling.
• System Integration  The MC68340 family integrates system configuration, external bus interface, chip select and wait‑state generation, interrupt response, and IEEE 1149.1 boundary scan (JTAG) functions.
• Power and Mounting  I/O voltage is specified at 5 V; the device is surface‑mount in a 144‑BQFP / 144‑QFP (28×28 mm) package. Series features include static HCMOS technology and power control modes for reduced consumption.
• Operating Temperature  Specified commercial temperature range of 0 °C to 70 °C for this part number.
• Regulatory  RoHS compliant.

Typical Applications

• Embedded Control Systems  Use as a compact control CPU where integrated timers, USARTs, and DMA simplify interfacing to sensors, actuators, and control subsystems.
• General‑Purpose Embedded Computing  Suitable for embedded computing tasks that benefit from a 32‑bit core and integrated bus/peripheral support.
• High‑Speed Block Transfer Systems  Systems that require efficient memory-to-memory or peripheral-to-memory transfers can leverage the MC68340 series DMA capabilities to reduce CPU overhead.
• Serial Communications Equipment  Applications requiring multi‑channel serial I/O and modem control can utilize the on‑chip USART resources.

Unique Advantages

• Highly integrated solution: Combines a CPU32 core, DMA controller, serial interfaces, timers, and system integration module on a single IC, reducing BOM and board space.
• Efficient block transfers: On‑chip DMA (two‑channel) enables sustained high‑speed transfers, lowering CPU load for data‑movement intensive tasks.
• Robust system integration: Built‑in bus arbitration, chip selects, wait‑state generation, and boundary scan support simplify system design and validation.
• Clear power and mounting choices: 5 V I/O operation and a surface‑mount 144‑QFP (28×28 mm) package support standard PCB assembly and system power architectures.
• Developer ecosystem compatibility: Series documentation cites upward object‑code compatibility with MC68000 family code and support for established embedded toolchains (as noted for the MC68340 series).
• Regulatory compliance: RoHS compliant for use in designs where lead‑free component status is required.
