FAQs

What is AT28C64B-15PU?

The AT28C64B-15PU is a high-performance 64K (8K x 8) parallel EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Microchip Technology. It is designed for applications that require non-volatile storage of data and configuration parameters, such as embedded systems, microcontroller-based designs, and legacy industrial equipment.

How Does AT28C64B-15PU Work?

The AT28C64B-15PU works by storing binary data in non-volatile memory cells, which can be electrically programmed and erased. It features a parallel interface for easy integration with microcontrollers and other digital systems. Data can be read from and written to the memory using appropriate control signals and timings.

How Many Pins does AT28C64B-15PU have and What are the Functions of the Pinout Configuration?

The AT28C64B-15PU is housed in a 28-pin DIP (Dual In-line Package) package. The pinout configuration includes:

A0 to A13: Address input pins for selecting memory locations.
Q0 to Q7: Data output pins for reading memory contents.
CE: Chip enable input for activating the device.
OE: Output enable input for enabling data output.
WE: Write enable input for initiating write operations.
VCC, GND: Power supply and ground pins, respectively.
NC: No connection pin.
