MC68LC302PU20VCT

Microprocessors Overview

The MC68LC302PU20VCT is a low-cost integrated multiprotocol processor based on the MC68302 architecture. It features a static M68000 core operating at 20 MHz with an 8- or 16-bit system bus. The device includes two serial communication controllers (SCCs), three timers, and 1152 bytes of dual-port RAM. Packaged in a 100-pin Thin Quad Flat Pack (TQFP), it supports 3.3V operation within a temperature range of -40°C to +85°C.

Microprocessors Feature Summary

• Static 68000 core for low-power portable applications
• Two independent full-duplex serial communication controllers
• On-chip PLL supporting 32 kHz or 4 MHz crystals
• Low-profile 100-pin TQFP package

Microprocessors Applications

• PCMCIA cards
• Handheld devices
• Intelligent DMA-driven peripheral chips

Microprocessors Procurement Notes

Verify that the specific suffix 'VCT' aligns with the manufacturer's official ordering information for voltage and temperature ratings. Confirm the package type matches the required board space constraints. Ensure compatibility with existing development tools and emulator designs before finalizing procurement.

Microprocessors Selection Notes

Select this component when the third serial channel of the MC68302 is unnecessary. It is suitable for height-restricted environments like PCMCIA. Consider its static core for power-sensitive designs. Note that external bus mastership via standard arbitration is not supported.

Microprocessors Part Context

This part belongs to the MC68LC302 family, representing a cost-reduced version of the MC68302. It retains the core functionality while removing the third SCC and reducing pin count from 132 to 100. It maintains glueless memory interfacing capabilities.

Microprocessors Replacement Considerations

The MC68LC302RC20 serves as a Pin Grid Array alternative. The MC68LC302PU20 offers identical functionality in the same package but operates at a different temperature range.
