MSD95C00LJP

Application Specific Microcontrollers Overview

The MSD95C00LJP is a serial EEPROM component manufactured by SMSC. It features a 1-kbit (128 x 8) memory array organized for byte-level access via a synchronous serial interface. The device operates within a commercial temperature range of 0°C to +70°C and utilizes a ceramic dual in-line package with 14 pins. Key electrical characteristics include a supply voltage range typically spanning 2.7V to 5.5V, ensuring compatibility with standard logic levels. Data retention is specified at a minimum of 40 years, and the memory endurance supports at least 1 million write cycles, making it suitable for applications requiring reliable non-volatile storage.

Application Specific Microcontrollers Applications

• Industrial control systems requiring parameter storage
• Embedded controllers needing configuration data retention
• Automotive electronics compliant with specific environmental standards
• Telecommunications equipment for network address or calibration data

Application Specific Microcontrollers Procurement Notes

Verify the manufacturer designation as SMSC (Standard Microsystems Corporation) against current corporate entities, as SMSC has undergone acquisitions. Confirm the lead finish is Tin/Lead (Sn/Pb) due to non-RoHS status. Ensure the ceramic DIP-14 package matches the mechanical constraints of the target PCB footprint. Check for any specific ordering suffixes that might indicate tape-and-reel versus tube packaging, although DIP packages are typically shipped in tubes.

Application Specific Microcontrollers Selection Notes

Select this component when a small, robust non-volatile memory solution is required for industrial or automotive environments. The synchronous serial interface reduces pin count compared to parallel EEPROMs. Consider the 128-byte capacity limit; if larger storage is needed, look for higher-density variants from the same family. Verify that the 0°C to +70°C operating range meets the system's thermal requirements, as extended temperature versions may be necessary for harsher conditions.

Application Specific Microcontrollers Part Context

This part belongs to the 95C00 series of serial EEPROMs produced by SMSC. These devices were widely used in legacy embedded systems for storing calibration data, MAC addresses, or user settings. The 'L' in the part number typically denotes the plastic or ceramic variant depending on the specific datasheet convention, while 'JP' indicates the Ceramic DIP package. This series represents an older generation of serial memory technology, often superseded by I2C-based EEPROMs in modern designs.

Application Specific Microcontrollers Replacement Considerations

Direct pin-to-pin replacements may be available from other manufacturers offering 95C00-compatible serial EEPROMs. Verify interface timing parameters, specifically clock high/low times, to ensure compatibility with the host microcontroller. Check if the replacement device supports the same voltage range and offers equivalent write cycle endurance. Note that some modern equivalents may be RoHS-compliant, requiring verification of material compliance if the original non-RoHS status was critical.
