Z85C3010PEC

Overview

The Z85C3010PEC is a CMOS Serial Communication Controller (SCC) from the Z85C30 family, designed for nonmultiplexed bus microprocessors. It features two independent full-duplex channels with processing speeds up to 10 MHz. The device supports asynchronous, monosync, bisync, and SDLC/HDLC protocols. Electrical specifications include a supply voltage range of 4.5V to 5.5V and an operating temperature range of -40°C to +105°C. It utilizes a 40-pin DIP package and includes on-chip baud rate generators and digital phase-locked loops.

Feature Summary

• Dual full-duplex communication channels optimized for nonmultiplexed bus architectures
• Supports multiple protocol formats including asynchronous, bisync, and SDLC/HDLC modes
• Integrated clock management with programmable baud rate generators and digital phase-locked loops per channel
• Hardware-assisted error detection using CRC-16 or CRC-CCITT algorithms

Applications

• High-speed data communication in intelligent transportation systems
• Serial communication interfaces for moving target recognition systems
• TDMA-based data link control implementations
• General-purpose networking applications requiring robust serial I/O

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements as standard versions may not meet current environmental directives. Validate package integrity upon receipt, ensuring no physical damage to the 40-pin DIP leads. Check manufacturing date codes against project timelines given the discontinued lifecycle.

Selection Notes

Select this part when interfacing with nonmultiplexed address/data buses requiring dual-channel synchronous or asynchronous communication. Compare against Z80C30 variants if multiplexed bus compatibility is required instead. Ensure system power supplies remain within the 4.5V to 5.5V range. Consider thermal management capabilities given the extended industrial temperature rating compared to commercial grade alternatives.

Part Context

This component belongs to the Zilog Z85C30 series of CMOS SCCs, which are pin and software compatible with NMOS predecessors like the Z80230. The Z85C3010PEC specifically denotes the 10 MHz speed grade in a PDIP-40 package with industrial temperature ratings. It serves as a successor to older NMOS controllers, offering lower power consumption and higher performance while maintaining legacy software compatibility.

Replacement Considerations

Z85C3010PSC offers identical functionality but with a commercial temperature range (0°C to +70°C). Z85C3010VEC provides the same electrical characteristics in a PLCC-44 surface mount package. For multiplexed bus applications, the Z80C3010PSC is the functional equivalent.
