HD64180ZRCP8V

Microprocessors Overview

The HD64180ZRCP8V is an 8-bit microprocessor from the Renesas Electronics Corporation, part of the Hitachi SH-2 family. It operates at a maximum clock frequency of 20 MHz and utilizes CMOS technology. The device features a 20-bit address bus width and an 8-bit external data bus width. It is housed in an 84-pin Plastic Quad Flat Package (PQCC84), also identified as LCC-84. The processor supports fixed-point format operations and includes two DMA channels along with four external interrupt devices. It incorporates two serial I/O interfaces and offers low-power operating modes.

Microprocessors Feature Summary

• Supports 8-bit data processing with a 20-bit address bus for extended memory addressing capabilities
• Integrates dual Direct Memory Access (DMA) channels to facilitate efficient data transfer without CPU intervention
• Includes multiple external interrupt sources and serial communication interfaces for versatile peripheral connectivity
• Designed with low-power operational modes to optimize energy consumption during idle or active states

Microprocessors Applications

• Industrial control systems requiring robust 8-bit processing
• Embedded applications utilizing serial communication protocols
• Systems benefiting from direct memory access for high-throughput data handling
• Portable or battery-operated devices leveraging low-power modes

Microprocessors Procurement Notes

Verify component authenticity through authorized distributors due to potential availability from secondary markets. Confirm package integrity upon receipt, as historical reports indicate occasional packaging damage. Ensure compliance with RoHS directives if required by your specific application standards. Check for any end-of-life notices or production change notifications that may affect long-term supply stability.

Microprocessors Selection Notes

Select this component when an 8-bit architecture with a 20-bit address space is sufficient for the application. Consider the 20 MHz speed limit against system timing requirements. Evaluate the need for DMA and external interrupts to determine if this hardware support aligns with software design goals. Compare pin count and package type against PCB layout constraints.

Microprocessors Part Context

This microprocessor belongs to the broader SH-2 series developed by Hitachi, now under Renesas Electronics. It represents a legacy 8-bit solution designed for cost-effective embedded control tasks. The device complements higher-performance 32-bit offerings by providing a simpler instruction set and lower power profile for specialized industrial and consumer electronics applications.

Microprocessors Replacement Considerations

Consult official Renesas documentation for cross-reference lists. Verify compatibility with existing firmware and hardware interfaces before substituting with other 8-bit microprocessors from the same or different families.
