The AT27C256R-55PC is an integrated circuit (IC) component manufactured by Microchip Technology Inc. It is a High-Speed 256K (32K x 8) EPROM (Erasable Programmable Read-Only Memory) with a voltage range of 4.5V to 5.5V.
Key features of the AT27C256R-55PC include:
1. High-Density Memory: The IC offers a memory storage capacity of 256K bits (32 kilobytes). It is organized as 32,768 words of 8 bits each. This allows for storing a significant amount of program code or data.
2. EPROM Technology: It utilizes EPROM technology, which means the memory can be programmed electrically and then remains permanently stored even after power is turned off. However, it cannot be reprogrammed or modified once programmed (erased).
3. High-Speed Operation: The AT27C256R-55PC supports high-speed operation with access times as fast as 55 nanoseconds. This ensures efficient data retrieval and execution of code stored in memory.
4. Low Power Consumption: The IC component is designed to consume minimal power, making it suitable for low-power applications where energy efficiency is important.
5. Wide Operating Voltage Range: It can operate within a voltage range of 4.5V to 5.5V, providing flexibility in power supply options and compatibility with various systems
