Description and Introduction

512K 64K x 8 OTP CMOS EPROM The AT27C512R-12JC is a 512K (64K x 8) UV erasable and electrically programmable read-only memory (EPROM) manufactured by Microchip Technology (formerly Atmel). Here are its key specifications:

- **Memory Size**: 512 Kbit (64K x 8)  
- **Access Time**: 120 ns  
- **Operating Voltage**: 5V ±10%  
- **Power Consumption**:  
  - Active Current: 30 mA (max)  
  - Standby Current: 100 µA (max)  
- **Programming Voltage (VPP)**: 12.5V  
- **Package**: 28-lead PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range**:  
  - Commercial: 0°C to +70°C  
  - Industrial: -40°C to +85°C  
- **Data Retention**: 10 years minimum  
- **Endurance**: 1000 erase/write cycles  
- **UV Erasure**: Wavelength 2537 Å, 15W-sec/cm² minimum exposure  

The device features a single 5V power supply for read operations and requires a 12.5V supply for programming. It is compatible with standard EPROM programmers and supports a fast programming algorithm.
