Overview
The Microchip Technology AT28BV256-20PC is a high-performance 256Kbit parallel EEPROM designed for robust data storage in embedded systems. Its primary function is non-volatile data retention, crucial for configuration parameters and firmware. A key design consideration is the trade-off between access speed and power consumption; while the 200 ns access time is suitable for many applications, designers must carefully manage write cycle times (10ms) to avoid performance bottlenecks in high-throughput scenarios, especially when operating at the lower end of its 2.7V supply voltage range.
Key Features
- Memory Size: 256Kbit (32K x 8)
- Interface: Parallel
- Access Time: 200 ns
- Voltage Range: 2.7V to 3.6V
- Operating Temperature: 0°C to 70°C
- Package: 28-DIP (0.600″ width)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Industrial control system configuration storage
- Automotive ECU parameter retention
- Medical device firmware updates
- Telecommunications equipment settings backup
