CDP1802BCDX

Microprocessors Overview

The CDP1802BCDX is an 8-bit CMOS microprocessor from the Intersil (Harris) 1800 series, housed in a 40-CDIP package. It operates with a maximum input clock frequency of 5.0 MHz at VDD = 5V and supports a recommended operating voltage range of 4V to 6.5V. This register-oriented CPU is designed for stored program systems, providing synchronous interfaces to memories and external I/O controllers.

Microprocessors Feature Summary

• Register-oriented architecture optimized for system flexibility and cost efficiency
• Synchronous interface capability for memories and external I/O controllers
• Supports polled, interrupt-driven, and direct memory access modes

Microprocessors Applications

• General purpose computing elements
• Control elements in stored program systems
• Microcomputer system designs requiring minimum interface controller cost

Microprocessors Procurement Notes

Verify the manufacturer origin, as the component is associated with both Harris Corporation and Intersil/Renesas. Confirm the specific suffix 'X' denotes the correct package variant against the official datasheet specifications. Ensure the device meets the required voltage and clock frequency parameters for your application design.

Microprocessors Selection Notes

Select this model when a 5 MHz clock speed is required within a 4V to 6.5V supply range. It serves as the higher-speed variant compared to the 3.2 MHz CDP1802A/AC. Choose this part for applications needing robust I/O control features and synchronous memory interfacing in an 8-bit embedded environment.

Microprocessors Part Context

This component belongs to the CDP1802 family of CMOS microprocessors. The 'BC' designation indicates the 5.0 MHz speed grade, distinguishing it from the slower 'A' and 'AC' versions. The 'DX' suffix typically refers to the specific package type and commercial temperature rating within the 40-pin CDIP form factor.

Microprocessors Replacement Considerations

The CDP1802AC or CDP1802A are functionally identical but operate at a lower maximum clock frequency of 3.2 MHz. Verify if the system timing requirements can accommodate the reduced speed before substituting.
