The AT28C256-15PU is a popular integrated circuit (IC) component, offering non-volatile memory storage in a 28-pin dual-in-line package (DIP). This IC is manufactured by Microchip Technology, and it belongs to the AT28C series of electrically erasable and programmable read-only memory (EEPROM) devices. Below is an overview of the key features and specifications of the AT28C256-15PU:
1. Memory Capacity: The AT28C256-15PU provides a total storage capacity of 256 kilobits (32 kilobytes). It uses a standard 8-bit data bus to read and write data.
2. Organization: The memory is organized into 32,768 words, with each word consisting of 8 bits (or 1 byte). This organization allows for efficient access and data retrieval.
3. High-Speed Performance: The "15PU" in the part number denotes the access time of 150 nanoseconds (ns). This signifies that data can be accessed or written in as little as 150 ns, enabling faster operation and responsiveness.
4. Low-Power Consumption: The AT28C256-15PU is designed with low-power consumption in mind. It features both an automatic power-down mode and a standby mode, allowing for efficient power usage when the memory is not actively accessed
