Description and Introduction

512 Kbit (64K x8) UV EPROM and OTP EPROM The **M27C512-20XF6** is an EPROM (Erasable Programmable Read-Only Memory) manufactured by **STMicroelectronics (ST)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 512 Kbit (64K x 8-bit)  
- **Access Time:** 200 ns (20XF6 denotes speed grade)  
- **Supply Voltage:** 5V ±10%  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package Type:** PDIP-28 (Plastic Dual In-line Package)  
- **Technology:** UV-erasable EPROM  
- **Programming Voltage (VPP):** 12.5V  
- **Standby Current:** 100 µA (max)  
- **Active Current:** 30 mA (max)  

### **Descriptions:**
- The M27C512 is a **non-volatile memory** that retains data when power is off.  
- It is **UV-erasable**, requiring exposure to ultraviolet light for data erasure.  
- Organized as **64K x 8 bits**, it is suitable for microprocessor-based systems.  
- Compatible with **JEDEC standards** for pinout and programming.  

### **Features:**
- **Low Power Consumption:** Supports standby mode for reduced power usage.  
- **High Reliability:** Endurance of **100 erase/program cycles**.  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing with logic circuits.  
- **Programmable Security Fuse:** Protects code from unauthorized access.  
- **Industrial-Grade Options Available** (e.g., M27C512-20XF1 for extended temperature range).  

This EPROM is commonly used in **embedded systems, industrial controls, and legacy computing applications**.
