Z8018010VSC

Overview

The Z8018010VSC is an 8-bit microprocessor unit based on the Z180 architecture, operating at a maximum clock frequency of 10 MHz. It features a single core with an 8-bit data bus width and utilizes a 68-pin PLCC package for surface mount installation. The device operates within a voltage range of 5 V and supports an industrial temperature range from 0°C to +70°C. Key integrated resources include two DMA channels, two UARTs, two programmable reload timers, and an MMU supporting up to 1 MB of addressable memory.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 CPU code while offering extended instructions and performance enhancements.
• Integrates multiple system functions on-chip, including dual DMA controllers, asynchronous serial communication interfaces (ASCI), and programmable reload timers.
• Features an expanded Memory Management Unit (MMU) that maps logical 64 KB into a 1 MB physical addressing range using a common area-banked area scheme.

Applications

• Embedded control systems requiring Z80 compatibility with enhanced I/O capabilities
• Industrial automation equipment utilizing integrated timer and serial communication functions
• Data acquisition systems employing direct memory access for high-speed peripheral transfers

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to end-of-life status. Confirm package integrity and pin alignment for the 68-PLCC form factor prior to assembly. Review latest product change notifications for any manufacturing updates. Ensure static discharge precautions are observed during handling. Validate supply chain documentation against current inventory records.

Selection Notes

Select this variant when a 10 MHz processing speed is required alongside integrated UART and DMA resources. The 68-PLCC package suits surface-mount designs needing robust connectivity. Consider thermal management requirements for the specified 0°C to +70°C operating range. Evaluate system memory mapping needs against the integrated MMU capabilities. Compare power consumption characteristics against alternative low-power variants if energy efficiency is critical.

FAQ

What is the primary architectural difference between the Z80180 and the standard Z80?

The Z80180 integrates additional system resources such as DMA controllers, UARTs, and timers directly onto the chip, whereas the standard Z80 requires external components for these functions.

How does the MMU function in the Z80180?

The MMU allows the CPU to access up to 1 MB of memory by mapping the logical 64 KB address space into different banks, maintaining object-code compatibility with the Z80.
