COM78C802P

Overview

The COM78C802P is a synchronous serial interface controller manufactured by SMSC, designed to facilitate communication between host processors and external devices using the SPI protocol. It supports multiple slave device connections through configurable chip select lines. The component operates within standard voltage ranges typical for CMOS logic families and provides reliable data transfer capabilities for embedded systems requiring serial peripheral management.

Feature Summary

• Supports synchronous serial communication via SPI interface
• Configurable chip select outputs for multi-slave connectivity
• Compatible with standard host processor architectures

Applications

• Embedded system serial port expansion
• Multi-device SPI bus management
• Industrial control interface modules

Procurement Notes

Verify the manufacturer designation as SMSC or its successor entities during sourcing. Confirm package type and pinout compatibility with existing board layouts. Ensure RoHS compliance status matches project requirements. Request official datasheets to validate electrical characteristics before integration.

Selection Notes

Select this component when SPI interface expansion is required without complex FPGA logic. Evaluate power consumption against system constraints. Compare pin count and package options with available footprint designs. Verify operating temperature range suitability for the intended environment.

Part Context

SMSC specialized in interface controllers for computing and industrial applications. This part belongs to their serial communication portfolio. The company's assets were acquired by Microchip Technology. Legacy parts may still be referenced under the original branding in older designs.

Replacement Considerations

Check Microchip Technology documentation for direct equivalents. Verify pin-to-pin compatibility if substituting. Review updated feature sets in newer generations of SPI controllers.
