Z8523016VEC

Specialized Overview

The Z8523016VEC 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 operates within a voltage range of 4.5V to 5.5V and utilizes a 44-pin PLCC package. It supports multiple protocols including async, monosync, bisync, SDLC/HDLC, and SDLC/HDLC loop modes. Encoding options include NRZI, FM0, FM1, and Manchester. Error detection is provided via CRC-16 or CRC-CCITT. The component includes a 4-byte transmit FIFO and an 8-byte receive FIFO per channel.

Specialized Feature Summary

• Dual full-duplex serial communication channels
• Support for multi-protocol formats including SDLC/HDLC
• Integrated FIFO buffers for data handling
• Hardware error detection capabilities

Specialized Applications

• Networking applications requiring serial interface control
• Systems utilizing SDLC/HDLC protocol standards
• Embedded controllers needing high-speed serial data transmission

Specialized Procurement Notes

Verify the specific suffix 'VEC' confirms the 44-pin PLCC package and -40°C to +100°C operating temperature range. Confirm RoHS compliance status as datasheets may indicate non-compliance for older manufacturing runs. Check current availability as this part number may be discontinued or superseded by newer revisions in the Z85230 family.

Specialized Selection Notes

Select the Z8523016VEC when dual-channel synchronous or asynchronous communication is required with speeds up to 5 Mbps. Ensure the system design accommodates the 44-pin PLCC footprint. Compare against the Z8523010VEC if lower clock speeds are sufficient, or consider the Z16C30 series for higher performance requirements exceeding 5 Mbps.

Specialized Part Context

This component belongs to the Z85230 enhanced SCC family, designed to reduce CPU overhead through integrated packet handling and FIFOs. It shares architectural similarities with the Z80230 but offers optimized features for specific networking implementations. The '16' designation indicates support for clock frequencies up to 16 MHz, enabling the stated 5 Mbps data rate.

Specialized Replacement Considerations

The Z8523016VSC is a direct alternative offering the same functionality in a plastic SC package instead of ceramic PLCC. For higher speed requirements, the Z16C3016 series provides increased processing speeds up to 10 Mbps while maintaining similar interface characteristics.
