Z8523010VSC00TR

Specialized Overview

The Z8523010VSC00TR is a Serial Communication Controller (SCC) from the Z85230 family, manufactured by Zilog. It features dual full-duplex channels and supports processing speeds up to 5 Mbps. The device accommodates a crystal oscillator, baud rate generator, and digital phase-locked loop on each channel. It handles multi-protocol formats including async, monosync, bisync, SDLC/HDLC, and SDLC/HDLC loop. Encoding modes include NRZI, FM0, FM1, and Manchester. Error detection utilizes CRC-16 or CRC-CCITT. The component includes a 4-byte transmit FIFO and an 8-byte receive FIFO. It operates within a voltage range of 4.5V to 5.5V and is housed in a 44-pin PLCC package.

Specialized Procurement Notes

Verify the exact part number against manufacturer documentation as suffixes may indicate specific packaging or environmental ratings. Confirm availability status, as this component is listed as obsolete in some distributor databases. Ensure compatibility with existing system voltage levels and interface requirements before procurement.

Specialized Selection Notes

Select this component when dual-channel synchronous or asynchronous serial communication is required. Compare performance metrics such as FIFO depth and maximum clock speed against other SCC family members like the Z85C30 series if higher integration or different pin counts are needed. Verify temperature range requirements match the industrial specifications.

Specialized Part Context

This component belongs to the Z85230 enhanced SCC family, designed to reduce CPU overhead through hardware-assisted packet handling. It shares architectural similarities with the Z80230 but offers optimized features for specific application needs. The Z85230 series represents a standard in serial communication control within the ZiLOG product line.

Specialized Replacement Considerations

Direct replacements within the same family include the Z8523010PSC (DIP package) or Z8523010VEC (PLCC package). Cross-family alternatives like the Z85C30 series offer similar functionality but may differ in multiplexing capabilities and package options.
