Description and Introduction

CMOS SERIAL E2PROM The S-93C66ADFJ is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by ABLIC Inc. (formerly Seiko Instruments).  

### **Key Specifications:**  
- **Memory Capacity:** 4K-bit (512 x 8-bit or 256 x 16-bit organization)  
- **Interface:** Microwire (3-wire serial interface)  
- **Operating Voltage:** 1.7V 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 SOP (Small Outline Package)  

### **Features:**  
- Low power consumption  
- Software write protection  
- Sequential read operation  
- Self-timed programming cycle  
- Built-in noise filter for stable operation  

This EEPROM is commonly used in automotive, industrial, and consumer electronics for storing configuration data.

Application Scenarios & Design Considerations

CMOS SERIAL E2PROM

Alternative Part Number

  • M93C66-WMN6TP --: Same 4Kbit 93C66 serial EEPROM with identical SPI-like microwire interface and pinout, widely available and a direct functional drop-in.
  • CAT93C66VI-GT3 --: 4Kbit microwire EEPROM in SOIC-8 matching the S-93C66ADFJ function and package, with comparable voltage range and timing.
  • BR93L66RFJ-WE2 --: 4Kbit 93C66-series serial EEPROM in SOP-8, same organization and interface, suitable as a cross-manufacturer replacement.
