Z8S18010PEC

Overview

The Z8S18010PEC is an enhanced microprocessor from the Zilog Z8S180 series, featuring a Z80-compatible core with extended instructions. It operates at a maximum clock frequency of 10 MHz and supports a data bus width of 8 bits. The device utilizes a 64-pin DIP package for through-hole mounting. It functions within a supply voltage range of 5 V and maintains an operating temperature range from -40°C to +100°C.

Feature Summary

• Provides full backward compatibility with existing ZiLOG Z80 devices while offering faster execution speeds and EMI noise reduction.
• Integrates two chain-linked DMA channels that allow for nonstop operation between peripherals.
• Includes two Enhanced UARTs capable of asynchronous data transfer rates up to 512 Kbps with FIFO buffers.
• Offers multiple low-power-down modes including Stop, Sleep, and Power-Down states to reduce current consumption.

Applications

• Industrial control systems requiring robust I/O capabilities
• Embedded applications needing extended memory addressing via MMU
• Communication interfaces utilizing dual UARTs and CSI/O ports

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment prior to installation. Ensure compliance with relevant environmental regulations such as RoHS standards applicable to your region. Review datasheet specifications for correct voltage levels and timing requirements to prevent operational faults.

Selection Notes

Select this model when Z80 code compatibility is required alongside integrated system resources. Consider the 64-pin DIP form factor for prototyping or legacy board designs. Evaluate the 10 MHz speed against higher-frequency variants if power consumption or thermal management are critical constraints for the specific application environment.

Part Context

This component belongs to the Z8S180/Z8L180 family of enhanced microprocessors. These devices combine a high-performance CPU core with on-chip peripherals such as DMA controllers, timers, and serial interfaces. The Z8S180 variant typically supports standard voltage operations, distinguishing it from the low-power Z8L180 series.
