Description and Introduction

1024-Bit Serial CMOS EEPROM (MICROWIRE? Synchronous Bus) The **NM93C46EN** is a serial Electrically Erasable Programmable Read-Only Memory (EEPROM) component designed for non-volatile data storage in a wide range of electronic applications. With a storage capacity of 1K-bit (128 x 8 or 64 x 16 organization), it provides reliable and flexible memory solutions for systems requiring small-scale data retention.  

This EEPROM operates over a broad voltage range, typically between 2.5V and 5.5V, making it suitable for both low-power and standard voltage environments. It features a **3-wire serial interface** (compatible with Microwire protocol), ensuring straightforward integration with microcontrollers and other digital systems.  

Key attributes of the NM93C46EN include **high endurance** (up to 1 million write cycles) and **long data retention** (up to 100 years), ensuring robust performance in demanding conditions. Additionally, it supports both sequential and random read operations, enhancing efficiency in data retrieval.  

Common applications include **consumer electronics, industrial automation, automotive systems, and embedded devices**, where reliable parameter storage is essential. Its compact form factor and low power consumption further contribute to its versatility in modern electronic designs.  

The NM93C46EN remains a dependable choice for engineers seeking a cost-effective, high-performance EEPROM solution for non-volatile memory needs.

Application Scenarios & Design Considerations

1024-Bit Serial CMOS EEPROM (MICROWIRE? Synchronous Bus)

Alternative Part Number

  • 93C46-E/P --: Pin-compatible 1Kbit Microwire serial EEPROM in DIP-8, direct functional replacement for the NM93C46EN with the same organization and interface.
  • AT93C46-10PU-2.7 --: 1Kbit 3-wire serial EEPROM with matching pinout and command set, widely available and commonly used as a drop-in substitute for NM93C46 parts.
  • CAT93C46VI-GT3 --: 1Kbit Microwire EEPROM with compatible pinout and protocol, suitable alternative when the original NS device is unavailable.
  • AT93C46D-PU --: Direct functional equivalent 1Kbit Microwire EEPROM with matching pinout and command set, suitable drop-in replacement in most designs.
  • M93C46-WMN6TP --: Industry-standard 1Kbit serial EEPROM with compatible organization and interface, offering a second-source option with good availability.
