Overview
The CP1854ACD is a serial communication controller manufactured by Harris Corporation, belonging to the CDP1854 series. It supports data rates up to 200 kbps and features a single channel configuration. The device is housed in a 40-pin Ceramic Dual In-line Package (CDIP). It operates within a standard industrial temperature range of -55°C to +125°C and utilizes CMOS technology for low power consumption. This component functions as a versatile interface for asynchronous serial data transmission and reception.
Feature Summary
- Integrated serial communication controller with dedicated transmit and receive channels
- Supports programmable baud rate generation and data framing formats
- Designed for high reliability operation in demanding industrial environments
- CMOS construction ensures compatibility with standard logic families
Applications
- Industrial automation systems requiring robust serial data links
- Military and aerospace telemetry equipment
- Computer peripheral interfaces for legacy serial devices
- Data acquisition systems with high noise immunity requirements
Procurement Notes
Verify the specific suffix 'D' indicates the ceramic package variant against official datasheets. Confirm RoHS compliance status as older Harris components may not meet current environmental directives. Validate pinout compatibility if replacing existing designs, as CDIP packages differ from plastic equivalents.
Selection Notes
Select this component when a ruggedized ceramic package is required for extreme temperature stability. Ensure the system design accommodates the 40-pin CDIP footprint. Compare performance metrics against newer CMOS alternatives if cost or availability is a primary constraint, while maintaining the necessary serial protocol support.
Part Context
This part is part of the Harris CDP1854 family of serial controllers. It shares functional similarities with the CDP1854AC/3 but differs in packaging. Harris Corporation was a significant producer of semiconductor components before its acquisition by Intersil, which later became part of Renesas Electronics.
Replacement Considerations
The CDP1854AC/3 is a documented equivalent offering identical functionality in a different package style. Verify that the target replacement maintains the same voltage levels and timing characteristics to ensure seamless integration into existing serial communication circuits.
