    AT27C256R-70JU Typical application Circuitry


    High-performance 256K (32K x 8) Electrically Erasable Programmable Read-Only Memory (EEPROM) is available in the Microchip Technology AT27C256R-70JU. It features fast read and write access times and is designed for applications where low-power and high-reliability memory storage is required. Here's a brief guide on connecting the AT27C256R-70JU EEPROM:

    1. Power Supply: The VCC (pin 28) should be connected to the power supply, typically between 4.5V and 5.5V.It is necessary to connect the ground to pin 1, or GND.

    2. Address Inputs: The A0 to A14 pins (pins 2 to 15) are the address inputs. These pins determine the memory location to be accessed. Connect these pins to your microcontroller or address bus accordingly, depending on the desired memory address.

    3. Data Inputs/Outputs: The D0 to D7 pins (pins 16 to 23) are the bidirectional data pins. Connect these pins to your microcontroller or data bus to read from or write to the EEPROM.

    4. Chip Enable and Output Enable: The CE (pin 27) and OE (pin 26) pins control the chip enable and output enable operations. Connect these pins to the corresponding control signals from your microcontroller. Typically, the CE pin is active-low, while the OE pin is active-low or active-high, depending on the specific device variant.

    5. Write Enable: The (pin 24) pin controls to write enable operation. Connect this pin to the corresponding control signal from your microcontroller. Typically, the WE pin is active-low.

    The above represents a basic connection scheme for the AT27C256R-70JU EEPROM. Please refer to the data sheet and relevant documentation from Microchip Technology for more detailed information, including timing diagrams, programming considerations, and additional electrical characteristics.
