Z16C3510VSC

Specialized Overview

The Z16C3510VSC is a CMOS Integrated Serial Communications Controller (ISCC) manufactured by Zilog, Inc. It operates with a maximum clock frequency of 10 MHz and supports an external data bus width of 16 bits. The device is housed in a PLCC-68 package (QCCJ, LDCC68, 1.0SQ) with 68 pins. It features four DMA channels and supports multiple communication protocols including ASYNC, BIT, SYNC BYTE, SYNC HDLC, SYNC SDLC, BISYNC, and EXT SYNC. Data encoding methods include NRZ, NRZI-SPACE, BIPH-MARK(FM1), BIPH-SPACE(FM0), and BIPH-LEVEL(MANCHESTER). The component has a maximum data transmission rate of 0.5 MBps and utilizes a 16-bit address bus.

Specialized Feature Summary

• Supports multiple synchronous and asynchronous serial communication protocols including HDLC, SDLC, and BISYNC.
• Integrates four DMA channels for efficient data transfer management.
• Provides versatile data encoding options such as NRZ, NRZI, FM1, FM0, and Manchester coding.
• Compatible with 68000 and 8086 bus architectures.

Specialized Applications

• Integrated serial communications controller applications
• Modem control interface systems
• General-purpose I/O expansion using modem control lines

Specialized Procurement Notes

Verify the specific suffix VSC against official Zilog documentation to confirm pinout and electrical characteristics, as suffixes often denote package type or temperature range. Confirm RoHS compliance status, as some listings indicate non-compliance. Check for End-of-Life (EOL) status and lead time constraints from authorized distributors. Ensure moisture sensitivity level (MSL) handling procedures are followed during assembly.

Specialized Selection Notes

Select the Z16C3510VSC when a dedicated serial communications controller is required for 16-bit microprocessor systems. It is suitable for designs needing hardware support for complex protocols like HDLC or SDLC without heavy CPU overhead. Consider the PLCC-68 package availability and board space requirements. Verify that the 10 MHz maximum clock speed meets the system timing requirements.

Specialized Part Context

The Z16C3510VSC belongs to the Z16C35 series of integrated serial communications controllers. This series was designed to offload serial communication tasks from the main processor in embedded systems. The VSC suffix typically indicates a specific plastic leaded chip carrier package variant within the Z16C35 family, distinct from other package types like QSD or VSG.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate legacy Zilog ISCC variants or modern UART/SPI controllers depending on protocol requirements. Verify pin compatibility if considering direct replacements.
