Description and Introduction

2K-BIT/4K-BIT SERIAL ELECTRICALLY ERASABLE PROM The IS93C66A-2GRLI is a 4K-bit (256 x 16 or 512 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by ISSI (Integrated Silicon Solution Inc.).  

### **Key Specifications:**  
- **Memory Organization:**  
  - 256 x 16-bit or 512 x 8-bit  
- **Interface:** Microwire-compatible serial interface  
- **Supply Voltage:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Write Cycle Time:** 5ms (typical)  
- **Endurance:** 1,000,000 write cycles  
- **Data Retention:** 100 years  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  

### **Features:**  
- Low-power CMOS technology  
- Self-timed write cycle  
- Built-in write protection (software and hardware)  
- Sequential read operation  
- Industrial temperature range support  

This EEPROM is commonly used in applications requiring non-volatile memory storage, such as automotive, industrial, and consumer electronics.

Application Scenarios & Design Considerations

2K-BIT/4K-BIT SERIAL ELECTRICALLY ERASABLE PROM

Alternative Part Number

  • M95640-WMN6TP --: 4Kbit SPI EEPROM in SOIC-8, same 3-wire SPI interface and 2.5-5.5V range, pin-compatible with the IS93C66A and widely available.
  • AT93C66B-SSHM-T --: 4Kbit Microwire EEPROM in SOIC-8 with identical organization and pinout, direct functional replacement for the IS93C66A-2GRLI.
  • CAT93C66VI-GT3 --: 4Kbit Microwire serial EEPROM in SOIC-8, same 16-bit/8-bit selectable organization and supply range, suitable drop-in alternative.
