Description and Introduction

1 MBIT (128KB X8) UV EPROM AND OTP ROM The M27C1001 is an EPROM (Erasable Programmable Read-Only Memory) manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Memory Size:** 1 Mbit (128K x 8)  
- **Technology:** UV-erasable EPROM  
- **Supply Voltage:** 5V ± 10%  
- **Access Time:** 45 ns, 55 ns, 70 ns, 90 ns, 120 ns (depending on speed grade)  
- **Operating Temperature Range:**  
  - Commercial (0°C to +70°C)  
  - Industrial (-40°C to +85°C)  
- **Package Options:**  
  - 32-pin DIP (Dual In-line Package)  
  - 32-pin PLCC (Plastic Leaded Chip Carrier)  
  - 32-pin TSOP (Thin Small Outline Package)  

### **Descriptions:**  
- The M27C1001 is a high-performance, low-power EPROM designed for applications requiring non-volatile memory.  
- It features a transparent quartz window for UV erasure, allowing the memory to be reprogrammed after exposure to ultraviolet light.  
- The device is compatible with standard EPROM programmers.  

### **Features:**  
- **Low Power Consumption:**  
  - Active current: 30 mA (typical)  
  - Standby current: 100 µA (typical)  
- **Fast Read Access Time:** Up to 45 ns (depending on speed grade)  
- **CMOS Technology:** Ensures high noise immunity and low power consumption.  
- **Programmable:** Supports standard programming algorithms.  
- **Reliable:** High endurance (typically 100 erase/program cycles).  

This information is based solely on the manufacturer's datasheet for the M27C1001 EPROM.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • AM27C010 --: 1 Mbit (128K x 8) UV EPROM with the same 32-pin DIP pinout and access-time grades, a well-known second source for the M27C1001.
  • 27C010 --: 1 Mbit CMOS EPROM in a compatible 32-pin package with matching pinout and timing, widely available as a drop-in replacement.
  • SST27SF010 --: 1 Mbit flash/EPROM-compatible device with the same 32-pin pinout and 5V operation, usable where in-system reprogrammability is acceptable.
  • 27C1001 --: Same 1 Mbit EPROM family from the original ST line, matching pinout and programming characteristics, suitable when the exact ST series is preferred.
