Description and Introduction

32K X 8 ELECTRICALLY ERASABLE EPROM The part **W27E257-10** is manufactured by **WINBOND**. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** EEPROM (Electrically Erasable Programmable Read-Only Memory)  
- **Density:** 256K (32K x 8)  
- **Speed:** 100 ns (Access Time)  
- **Voltage Supply:** 5V ±10%  
- **Operating Temperature Range:** 0°C to +70°C (Commercial)  
- **Package:** 28-pin DIP (Dual In-line Package) or PLCC (Plastic Leaded Chip Carrier)  
- **Endurance:** 100,000 write/erase cycles  
- **Data Retention:** 10 years minimum  

### **Descriptions:**  
- The **W27E257-10** is a high-performance, byte-alterable EEPROM with a fast access time.  
- It is designed for applications requiring non-volatile memory storage with frequent updates.  
- Supports both parallel and serial programming modes.  

### **Features:**  
- **Low Power Consumption:** Active current of 30 mA (typical), standby current of 100 µA (max).  
- **Fast Read Access Time:** 100 ns.  
- **Byte-Write Capability:** Allows individual byte modification without full sector erasure.  
- **Hardware and Software Data Protection:** Prevents accidental writes.  
- **CMOS Technology:** Ensures high reliability and low power usage.  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing with standard logic circuits.  

This information is strictly factual and sourced from Ic-phoenix technical data files. No additional guidance or suggestions are included.
