Description and Introduction

1 MBIT (128KB X8) UV EPROM AND OTP ROM The **M27C1001-45XN1** is a 1 Megabit (128K x 8) UV erasable and electrically programmable read-only memory (EPROM) manufactured by **STMicroelectronics (ST)**.  

### **Key Specifications:**  
- **Memory Size:** 1 Mbit (128K x 8)  
- **Access Time:** 45 ns  
- **Supply Voltage:** 5V ± 10%  
- **Operating Current:** 30 mA (typical)  
- **Standby Current:** 100 µA (max)  
- **Programming Voltage (VPP):** 12.5V  
- **Technology:** CMOS  
- **Package:** PDIP-32 (Plastic Dual In-line Package)  
- **UV Erasable:** Yes (minimum 15 minutes under UV light)  
- **Data Retention:** 10 years minimum  

### **Features:**  
- **Low Power Consumption** (CMOS technology)  
- **Fast Access Time** (45 ns)  
- **JEDEC Approved Pinout** (compatible with industry standards)  
- **High Noise Immunity**  
- **TTL Compatible Inputs/Outputs**  
- **Programmable via Standard EPROM Programmer**  
- **Reliable Reprogramming** (min. 100 write/erase cycles)  

This EPROM is commonly used in embedded systems, industrial controls, and legacy computing applications requiring non-volatile memory storage.

Application Scenarios & Design Considerations

1 MBIT (128KB X8) UV EPROM AND OTP ROM

Alternative Part Number

  • AT27C010-45PC --: 1 Mbit (128K x 8) OTP EPROM with 45 ns access time in a 32-pin DIP, functionally equivalent to the M27C1001 and widely available.
  • AM27C010-45DC --: 1 Mbit UV-erasable EPROM with matching 45 ns speed and 32-pin DIP pinout, a direct drop-in replacement for the M27C1001.
  • SST39SF010A-45-4C-PH --: 1 Mbit flash memory with 45 ns access and 32-pin DIP pinout; a practical substitute when OTP/UV EPROMs are unavailable, though it is flash rather than EPROM.
