Z16C3010VEC

Overview

The Z16C3010VEC 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 direct support for the 680X0 and 8x86 families. The component operates within a supply voltage range of 4.5V to 5.5V and is housed 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 configurable for 8-bit or 16-bit wide data paths

Applications

• Serial-to-parallel and parallel-to-serial conversion in multiplexed or non-multiplexed bus systems
• High-speed data communications peripherals requiring multi-protocol support
• Applications utilizing DMA for automatic status transfer and device initialization

Procurement Notes

Verify the specific suffix 'VEC' corresponds to the 100-pin VQFP package and extended temperature rating if required. Confirm RoHS compliance status as older Zilog products may not meet current environmental standards. Check for obsolescence notices or product change notifications from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when dual-channel serial control with hardware protocol handling is necessary. Ensure the host system bus matches the USC's configurable 8-bit or 16-bit interface requirements. Consider the 100-pin VQFP footprint constraints during PCB layout. Verify that the operating temperature range meets the application's environmental specifications.

Part Context

The Z16C3010VEC belongs to the Z16C30 family of Universal Serial Controllers. This series provides sophisticated internal functions such as character counters and programmable clock factors. It serves as a versatile peripheral for managing complex serial data transfers across various industrial and computing applications.

Replacement Considerations

Consult the Zilog datasheet for pin-compatible alternatives within the Z16C30 series. Verify electrical characteristics and package dimensions for any substitute components to ensure mechanical and functional compatibility.
