MC68340AG16EB1

Microprocessors Overview

The MC68340AG16EB1 is a CPU32 microprocessor IC from the M683xx series, manufactured by NXP USA Inc. It features a single 32-bit core operating at a maximum speed of 16 MHz. The device utilizes a 144-LQFP (20x20) surface-mount package and supports I/O voltages of 5.0V. Key integrated peripherals include a DRAM controller and USART interfaces.

Microprocessors Feature Summary

• CPU32 Core: Delivers 32-bit CISC processor performance with upward object-code compatibility to MC68000 and MC68010, including additional 32-bit instructions.
• Two-Channel DMA Controller: Provides low-latency high-speed memory transfers supporting single- or dual-address modes with 32-bit addresses and counters.
• System Integration Module (SIM40): Incorporates external bus interface, system protection, clock generation, and up to 16 discrete I/O lines on-chip.
• Dual USART Modules: Features two independent universal synchronous/asynchronous receiver/transmitters compatible with MC68681/MC2681 standards.

Microprocessors Applications

• Embedded control systems requiring high functional integration
• General computing applications utilizing M68000 code compatibility
• Compact Disc-Interactive (CD-I) players

Microprocessors Procurement Notes

Verify component authenticity through authorized distributors as this part is discontinued. Confirm RoHS compliance status and check for moisture sensitivity level requirements during storage. Ensure replacement strategies account for the end-of-life status and potential availability constraints in the current market.

Microprocessors Selection Notes

Select this component when existing designs rely on the M683xx architecture or require specific backward compatibility with MC68000 software ecosystems. Evaluate the trade-off between the integrated peripheral count and board space savings versus the availability of modern alternatives. Consider the 16MHz operational limit and 5.0V I/O voltage requirements for system compatibility.

Microprocessors Part Context

This processor belongs to the Motorola/NXP M68300 family of integrated processors. It shares the CPU32 core found in related parts like the MC68302 and MC68330 but distinguishes itself through its specific combination of DMA channels and serial I/O modules. The device represents a transition point in the 68K family, offering enhanced 32-bit capabilities within a cost-effective 16-bit memory system framework.
