CDP6805E3D

Microprocessors Overview

The CDP6805E3D is an 8-bit microcontroller based on the 6805 CPU architecture, manufactured by Harris Corporation. It utilizes CMOS technology and is housed in a 40-pin ceramic dual in-line package (CDIP). The device operates at a maximum clock frequency of 4 MHz and supports a 16-bit address bus with an 8-bit external data bus. It contains 112 bytes of on-chip RAM and lacks internal program memory (ROM), requiring external storage. The component supports low-power modes and functions within a commercial temperature range.

Microprocessors Feature Summary

• CMOS-based 8-bit processing core compatible with standard 6805 instruction sets
• Ceramic dual in-line packaging for robust industrial environments
• Integrated low-power operational modes for energy efficiency
• Supports serial I/O and timer functionalities

Microprocessors Applications

• Industrial control systems requiring durable packaging
• Embedded applications utilizing external program memory
• Commercial electronic devices operating within standard temperature ranges

Microprocessors Procurement Notes

Verify the specific manufacturer source, as documentation lists both Harris Corporation and Renesas Electronics for this part number. Confirm the package material is ceramic CDIP rather than plastic DIP. Check RoHS compliance status, as listed data indicates non-compliance. Ensure the absence of internal ROM matches your system design requirements.

Microprocessors Selection Notes

Select this component when a rugged ceramic package is required for an 8-bit 6805-compatible system. It is suitable for designs that can accommodate external memory solutions due to the lack of onboard ROM. Consider the 4 MHz speed limit and commercial temperature rating against application demands.

Microprocessors Part Context

This microcontroller belongs to the CDP6805 series, which provides 8-bit processing capabilities using CMOS technology. The series includes variants with different memory configurations and packages. The CDP6805E3D specifically denotes the ceramic DIP variant without internal program memory, distinguishing it from EPROM or MROM versions in the same family.
