Z8L18020FSC00TR

Overview

The Z8L18020FSC00TR is an 8-bit microprocessor based on the Z180 core, manufactured by Zilog. It operates at a maximum clock speed of 20 MHz and features a single core architecture. The device is housed in an 80-pin QFP package with surface mount mounting type. It supports a 3.3V I/O voltage level and functions within an operating temperature range of 0°C to 70°C. Key integrated peripherals include two DMA channels, two ASCI interfaces, two UARTs, and two counter/timers.

Feature Summary

• Code compatible with ZiLOG Z80 CPU while providing extended instructions and faster execution speeds.
• Features two chain-linked DMA channels for high-speed data transfers between memory and I/O devices.
• Includes two enhanced asynchronous serial communication interfaces (ASCI) with FIFO buffers and baud rate generators.
• Offers multiple low-power-down modes to reduce consumption during idle or stopped states.

Applications

• Embedded systems requiring backward compatibility with Z80 instruction sets.
• Industrial control applications utilizing on-chip interrupt controllers and timers.
• Data acquisition systems leveraging DMA capabilities for efficient memory access.
• Communication modules employing dual UART/ASCI channels for serial data transfer.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation, noting potential non-compliance for specific variants. Check for End-of-Life (EOL) notices or Product Change Notifications (PCN) that may affect long-term availability. Ensure storage conditions adhere to Moisture Sensitivity Level (MSL) requirements to prevent damage prior to soldering.

Selection Notes

Select this component when system design requires Z80 code compatibility alongside enhanced peripheral integration. Consider the 80-QFP package for surface-mount assembly constraints. Evaluate power consumption requirements against available low-power modes if battery operation is critical. Verify that the 3.3V I/O voltage aligns with connected peripheral logic levels. Assess thermal management needs for the specified commercial temperature range.

Part Context

This part belongs to the Z8L180 series, which is an enhanced version of the Z80180 microprocessor. The Z180 architecture combines a high-performance CPU core with integrated system resources such as MMU, DMA, and serial interfaces. It serves as a bridge between legacy Z80 software ecosystems and modern embedded hardware requirements, offering improved performance and lower power consumption compared to earlier generations.
