Z85C3008VEC00TR

Specialized Overview

The Z85C3008VEC is a dual full-duplex serial communication controller designed for nonmultiplexed bus microprocessors. It operates within a voltage range of 4.5V to 5.5V and supports clock frequencies up to 8 MHz. The device features two independent channels, each equipped with a baud rate generator and digital phase-locked loop. It utilizes a 44-pin PLCC package and functions across an operating temperature range of -40°C to +105°C. Data transmission rates reach up to 5 Mbps, supported by a 1-byte transmit FIFO and a 3-byte receive FIFO per channel.

Specialized Feature Summary

• Supports multi-protocol formats including asynchronous, bisync, SDLC/HDLC, and extended synchronous modes.
• Provides flexible data encoding options such as NRZ, NRZI, FM0, FM1, and Manchester.
• Integrates on-chip CRC-16 or CRC-CCITT error detection capabilities.
• Includes local loopback and automatic echo modes for diagnostic testing.

Specialized Applications

• Networking applications requiring integrated serial communication solutions
• Systems utilizing nonmultiplexed bus architectures
• T1 digital trunk implementations

Specialized Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature rating. Confirm RoHS compliance status as older revisions may not meet current environmental standards. Check component availability and lifecycle status prior to design finalization.

Specialized Selection Notes

Select this model for designs requiring dual-channel serial control on nonmultiplexed buses. Ensure the system clock frequency does not exceed the rated maximum. Verify that the required FIFO depth meets application latency requirements compared to enhanced variants.

Specialized Part Context

This component belongs to the Zilog Z85C30 family of Serial Communication Controllers. It serves as a specialized interface for managing high-speed serial data transfers in embedded systems. The part replaces earlier NMOS versions while maintaining pin compatibility for easier upgrades.

Specialized Replacement Considerations

The Z85C3008VEG is a documented alternative offering RoHS3 compliance. Other family members like the Z85230 series provide enhanced FIFO depths but may require software adjustments.
