Z0801605PSC

Overview

The Z0801605PSC is a CMOS Direct Memory Access (DMA) controller manufactured by Zilog. It operates at a maximum clock frequency of 5 MHz and supports an 8-bit data bus width. The device is housed in a 48-pin Plastic Dual In-line Package (PDIP-48). It functions as a dedicated interface controller for managing data transfers between memory and I/O devices without CPU intervention.

Feature Summary

• Provides direct memory access capabilities to offload the central processing unit during data transfer operations
• Supports 8-bit data bus architecture for interfacing with compatible peripheral devices
• Utilizes CMOS technology for efficient power consumption and reliable digital logic performance

Applications

• Embedded systems requiring dedicated DMA management
• Industrial automation control interfaces
• Electronic equipment utilizing Zilog microprocessor architectures
