Z16C3010ASG

Overview

The Z16C30ASG 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. 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. Electrical specifications include a supply voltage range of 4.5 V to 5.5 V and an operating temperature range of 0°C to +70°C. The component is housed in a 100-pin LQFP package.

Feature Summary

• Dual-channel architecture with independent mode selection for receiver and transmitter
• Support for multi-protocol operation including Async, Bisync, HDLC/SDLC, and Transparent Bisync
• Integrated DMA interface with separate request and acknowledge signals per channel
• Flexible bus interface supporting 8-bit or 16-bit widths and multiplexed/non-multiplexed modes

Applications

• High-speed serial data communication systems
• Multiprotocol data communications peripherals
• Direct connection to microprocessors requiring 680X0 or 8x86 bus compatibility

Procurement Notes

Verify the specific suffix 'ASG' against current manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status as datasheets may indicate variations based on manufacturing date. Check for product discontinuation notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when dual-channel serial control with high throughput is required. Ensure the host system supports the necessary bus interface configuration. Verify that the application environment falls within the specified commercial temperature range. Consider the availability of programming tools and technical manuals for initialization.
