Z8018006PSC

Overview

The Z8018006PSC is an 8-bit microprocessor unit based on the Z80 architecture, manufactured by Zilog. It operates at a maximum clock frequency of 6 MHz and requires a 5 V supply voltage. The device integrates two DMA channels, two UARTs, two programmable reload timers, and a clock serial I/O port. It features an on-chip oscillator, interrupt controllers, wait-state generators, and an MMU supporting up to 1 MB of addressable memory. The component is housed in a 64-pin DIP package and supports through-hole mounting.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 devices while offering extended instructions and object-code compatibility.
• Integrates multiple system functions on-chip including DMA controllers, UARTs, timers, wait-state generators, and an interrupt controller to reduce system costs.
• Includes an expanded Memory Management Unit (MMU) allowing logical 64 KB mapping into a 1 MB physical addressing range.
• Features low power-down modes and an on-chip oscillator/generator for simplified system design.

Applications

• Embedded systems requiring reduced component count and cost
• Industrial control applications utilizing integrated I/O peripherals
• Legacy Z80 system upgrades or replacements

Procurement Notes

Verify the specific suffix 'PSC' against official Zilog documentation to confirm the package type (DIP-64), temperature range (0°C to +70°C), and lead-free status ('G'). Confirm availability status as distribution data indicates limited supply or end-of-life conditions. Ensure environmental compliance requirements match the RoHS designation found in current datasheets.

Selection Notes

Select this component when a Z80-compatible processor with integrated peripherals is required. The 6 MHz speed variant suits applications not demanding higher clock rates. Consider the 64-pin DIP package for through-hole prototyping or manufacturing. Verify that the integrated UARTs and DMA channels meet the specific interface needs without external logic.

Part Context

The Z80180 series belongs to Zilog's enhanced microprocessor family, combining the Z80 CPU core with extensive on-chip resources. This integration distinguishes it from standard Z80 CPUs by providing built-in DMA, serial communication, and timing functions. The series supports various clock speeds and packaging options to accommodate different performance and form factor requirements.

Replacement Considerations

Consult Zilog documentation for direct pin-compatible substitutes within the Z80180 series, such as variants with different clock speeds or temperature ranges. Verify that any replacement maintains the same DIP-64 package and electrical characteristics.
