Z8523010VSC

Specialized Overview

The Z8523010VSC is a Serial I/O Controller manufactured by Zilog, Inc. It operates at a maximum clock frequency of 20 MHz with a data transmission rate of 0.625 MBps. The device utilizes CMOS technology and is housed in a 44-pin Plastic Quad Flat Pack (PQCC44) package, also designated as LCC-44. It supports an operating temperature range from 0 °C to 70 °C.

Specialized Feature Summary

• Dual full-duplex serial communication channels
• Integrated baud rate generator and digital phase-locked loop
• Support for multiple protocols including async, bisync, and SDLC/HDLC
• On-chip FIFO buffers for transmit and receive operations

Specialized Applications

• Network interface controllers
• Modem control systems
• Industrial automation serial links
• Embedded system communication modules

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix VSC matches the required PLCC-44 plastic package and commercial temperature grade. Check RoHS compliance status as older revisions may not meet current environmental standards.

Specialized Selection Notes

Select this part when dual-channel synchronous or asynchronous serial communication is required within a standard 5V logic environment. Ensure the host processor bus interface is compatible with the SCC family architecture. Verify that the 44-pin PLCC footprint fits the target PCB layout constraints.

Specialized Part Context

This component belongs to the Z85230 enhanced serial communication controller family. It shares architectural similarities with the Z80230 and Z85C30 series but offers optimized features for reduced CPU overhead. The Z8523010VSC specifically denotes the 10 MHz variant in a plastic quad flat pack package.

Specialized Replacement Considerations

Z8523010VEC: Ceramic PLCC-44 package variant with extended temperature range. Z8523010PSC: DIP-40 package variant. Z8023010VSC: Multiplexed bus interface variant.
