Z16C3010AEC

Overview

The Z16C30AEC is a CMOS Universal Serial Controller (USC) manufactured by Zilog. It features two independent full-duplex channels supporting data rates up to 10 Mbps. Each channel includes dual baud rate generators, a digital phase-locked loop for clock recovery, and 32-byte FIFOs for both receiver and transmitter operations. The device supports asynchronous, synchronous byte-oriented, and bit-oriented protocols. It offers flexible bus interfaces compatible with the 680X0 and 8X86 families, selectable via software configuration. Electrical specifications include a supply voltage range of 4.5 V to 5.5 V and an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture with independent mode selection for each receiver and transmitter
• Support for multiple communication protocols including Async, Bisync, HDLC/SDLC, and X.21
• Integrated DMA interface with separate request and acknowledge signals per channel
• Flexible CPU bus interface supporting 8-bit or 16-bit widths and multiplexed/non-multiplexed modes

Applications

• High-speed serial data communications in industrial control systems
• Multiprotocol data transfer interfaces for microprocessor-based embedded systems
• Modem control and general-purpose I/O expansion in telecommunications equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package type matches design requirements, as the Z16C30 series is available in PLCC and VQFP formats. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this component when multi-protocol serial communication flexibility is required alongside high throughput. Consider the specific bus interface compatibility with the host processor, particularly regarding 680X0 or 8X86 family integration. Evaluate thermal management needs based on the extended temperature rating. Verify that the available pin count in the chosen package accommodates all necessary interrupt and DMA connections.

Part Context

The Z16C30 belongs to Zilog's USC family of universal serial controllers. It serves as a bridge between parallel microprocessor buses and serial communication lines. This specific part number denotes the AEC variant, which typically indicates an extended temperature range compared to standard commercial grades. It is designed to reduce system complexity by integrating protocol handling directly into the hardware.

Replacement Considerations

Direct replacements may be limited due to the age of the component. Potential alternatives include other Zilog USC variants within the same family, such as the Z85C30 series, provided pinouts and electrical characteristics are compatible. Cross-reference datasheets carefully to ensure protocol support and bus interface timing match the original design constraints.
