Z16C3010ASC

Overview

The Z16C3010ASC 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 utilizes a flexible bus interface compatible with 8-bit or 16-bit microprocessors, including the 680X0 and 8086 families. The component operates within a supply voltage range of 4.5V to 5.5V and is available in a 100-pin VQFP package.

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 MIL STD 1553B
• Integrated DMA interface with separate request and acknowledge signals for high-speed data transfers
• Flexible CPU bus interface supporting multiplexed and non-multiplexed configurations

Applications

• High-speed serial data communications systems
• Multiprotocol data transfer applications requiring software configuration
• Systems utilizing DMA for efficient bulk data movement
• Interfaces connecting to 680X0 or 8086 family microprocessors

Procurement Notes

Verify the specific suffix 'ASC' against the manufacturer's current ordering information to confirm package type and temperature rating. Confirm RoHS compliance status as older revisions may not meet current environmental standards. Check for end-of-life notifications or product discontinuance notices from Zilog before finalizing procurement plans.

Selection Notes

Select this component when dual-channel serial control with protocol flexibility is required. Ensure the host system supports the necessary bus timing characteristics, specifically the 110 ns bus cycle time. Verify that the application environment falls within the specified operating temperature range for the selected package variant. Consider the availability of programming tools such as the Programmer’s Assistant for initialization.

Part Context

The Z16C30 series represents a high-speed evolution of Zilog's Universal Serial Controllers, offering improved bus bandwidth compared to previous generations. The Z16C3010 model specifically denotes the base part number for this dual-channel controller. The 'ASC' suffix typically indicates the commercial temperature grade and the 100-pin VQFP packaging option, distinguishing it from other thermal or package variants within the same functional family.

Replacement Considerations

Consult the official Zilog documentation for direct cross-reference part numbers. Verify pin compatibility and register mapping if substituting with other USC models. Ensure any replacement maintains support for the required bus interface types and protocol specifications.
