Overview
The Intersil CDP65C51M4S2357 is a serial I/O controller manufactured using CMOS technology. It features one channel for asynchronous and bit-synchronous communication, supporting NRZ data encoding and decoding. The device operates with an external 8-bit data bus and utilizes a 2-bit address bus. It is housed in a CDIP-28 package. The component supports a maximum clock frequency of 4 MHz and functions within a temperature range of -55 °C to 125 °C.
Feature Summary
- Supports asynchronous and bit-synchronous communication protocols
- Integrates on-chip data RAM for buffer management
- Utilizes NRZ data encoding and decoding methods
Applications
- Serial interface control in industrial systems
- Data acquisition systems requiring serial I/O expansion
- Embedded controllers needing dedicated serial channels
Procurement Notes
Verify the manufacturer origin as Harris or Intersil due to corporate history changes. Confirm the specific suffix indicates the correct temperature grade and package variant. Check RoHS compliance status as original specifications may predate modern regulations. Ensure the ceramic DIP package matches the target board layout requirements.
Selection Notes
Select this component when a dedicated single-channel serial controller is required for high-temperature environments up to 125 °C. Compare against standard UARTs if hardware flow control or specific bit-synchronous modes are necessary. Verify that the 4 MHz clock limit meets the system timing constraints. Consider the CDIP-28 package availability for through-hole assembly processes.
Part Context
This part belongs to the CDP65C51 series of serial I/O controllers originally developed by Harris Semiconductor. The series provides hardware-managed serial communication interfaces. Intersil acquired Harris Semiconductor's assets, leading to the dual branding. The CDP65C51 family is designed for applications requiring reliable serial data transfer without heavy CPU intervention.
Replacement Considerations
Check for direct equivalents from the CDP65C51 series with compatible suffixes. Verify pin compatibility before substituting with other serial controllers. Ensure replacement parts support the same 4 MHz maximum clock speed and operating temperature range.
