MC68340FT16E

Microprocessors Overview

The MC68340FT16E is a 32-bit integrated processor featuring the CPU32 core, derived from the M68000 architecture. It operates at frequencies up to 16.78 MHz with a 5.0 V supply voltage and utilizes a 144-pin Ceramic Quad Flat Pack (CQFP) package. The device integrates two-channel DMA, dual USARTs, and timer modules within a System Integration Module (SIM40). It supports 32 address lines and 16 data lines, providing high functional integration for embedded control systems.

Microprocessors Feature Summary

• CPU32 core provides upward object-code compatibility with MC68000 and MC68010 processors.
• Two-channel low-latency DMA controller enables high-speed memory transfers without processor intervention.
• Dual Universal Synchronous/Asynchronous Receiver/Transmitters support baud rates up to 9.8 Mbps.
• System Integration Module consolidates bus arbitration, clock generation, and discrete I/O functions.

Microprocessors Applications

• Embedded control systems requiring high-performance processing
• General computing applications utilizing established real-time kernels
• Compact Disc-Interactive (CD-I) players meeting Green Book specifications

Microprocessors Procurement Notes

Verify component authenticity through authorized distribution channels due to legacy status. Confirm package integrity as the unit utilizes a ceramic quad flat pack construction. Ensure environmental compliance documentation aligns with project requirements. Validate operating temperature ranges against specific application constraints before finalizing procurement decisions.

Microprocessors Selection Notes

Select this component when system design requires direct code compatibility with existing M68000 software ecosystems. Evaluate the 16.78 MHz operational frequency against processing throughput needs. Consider the 5.0 V power supply requirement relative to available board power rails. Assess the 144-pin CQFP footprint availability against PCB layout constraints and assembly capabilities.

Microprocessors Part Context

This microprocessor belongs to the Motorola M68300 family of integrated processors. It shares architectural similarities with other family members like the MC68302 and MC68330, differing primarily in peripheral selection. The CPU32 core remains identical across these products, allowing driver software portability between different family variants while maintaining consistent instruction set execution characteristics.
