Description and Introduction

1,024-BIT SERIAL ELECTRICALLY ERASABLE PROM The IS93C46A-3GRL is a 1K-bit (64 x 16 or 128 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by Integrated Silicon Solution, Inc. (ISSI).  

### **Key Specifications:**  
- **Memory Organization:** Configurable as 64 x 16 or 128 x 8.  
- **Interface:** Microwire-compatible serial interface.  
- **Operating Voltage:** 2.7V to 5.5V.  
- **Operating Temperature Range:** -40°C to +85°C.  
- **Write Cycle Time:** 3ms (typical).  
- **Endurance:** 1,000,000 write cycles.  
- **Data Retention:** 100 years.  
- **Package:** 8-pin SOIC (150mil).  

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

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

Application Scenarios & Design Considerations

1,024-BIT SERIAL ELECTRICALLY ERASABLE PROM

Alternative Part Number

  • M93C46-WMN6TP --: Pin-compatible 1Kbit serial EEPROM in SOIC-8 with the same SPI-like Microwire interface, widely available and a direct functional drop-in for the IS93C46A.
  • AT93C46D-SSHM-T --: 1Kbit 3-wire serial EEPROM in SOIC-8, functionally equivalent to the IS93C46A with comparable voltage range and timing, from a major established supplier.
  • CAT93C46VI-GT3 --: 1Kbit Microwire serial EEPROM in SOIC-8 offering the same organization and interface, suitable as a lower-cost second-source alternative.
