M68LC302CPU16VCT

Microprocessors Overview

The M68LC302CPU16VCT is a low-cost integrated multiprotocol processor based on the MC68302 family. It features a static 68000 core supporting 16-bit system operation and operates at 16 MHz. The device integrates an independent DMA controller, interrupt controller, parallel I/O ports, and 1152 bytes of dual-port RAM. It includes three timers with a watchdog function and a periodic interrupt timer. The component utilizes a 100-pin TQFP package designed for height-restricted applications.

Microprocessors Feature Summary

• Integrates a static 68000 core for reliable system processing
• Includes dedicated hardware controllers for DMA and interrupts
• Features on-chip clock generation with PLL support
• Provides glueless interface to various memory types

Microprocessors Applications

• PCMCIA modules
• Height-restricted embedded systems
• Multiprotocol communication devices

Microprocessors Procurement Notes

Verify the specific suffix 'CT' against official NXP documentation to confirm tape-and-reel packaging details. Confirm RoHS compliance status as legacy Freescale/NXP parts may vary in environmental certification. Ensure the static core requirement aligns with power constraints. Validate pin compatibility if replacing older MC68302 variants lacking the third SCC.

Microprocessors Selection Notes

Select this component when a static 68000 architecture is required for deterministic timing without refresh cycles. It serves as a cost-effective alternative to the standard MC68302 by omitting the third serial controller. Choose this part for designs needing a compact 100-pin footprint suitable for PCMCIA form factors. Verify that the available dual-port RAM and timer resources meet the application's peripheral requirements.

Microprocessors Part Context

This part belongs to the MC68302 Integrated Multiprotocol Processor family, manufactured under NXP USA Inc. following the acquisition of Freescale Semiconductor. The MC68LC302 represents a low-cost variant optimized for specific market segments by reducing pin count and removing non-essential peripherals while maintaining core functionality.

Microprocessors Replacement Considerations

The MC68302 is the primary functional predecessor. Verify if the absence of the third Serial Communication Controller (SCC) impacts the target design. Check for availability of the MC68EC302 if an external bus interface is needed instead of the internal glueless logic.
