The AT27C1024-70JU is a 1Mb (128K x 8) one-time programmable (OTP) CMOS EPROM. It comes in a 32-pin PLCC (Plastic Leaded Chip Carrier) package. The primary functions of its pins are as follows:
- Address Inputs (A0-A16): These are used to select the memory location from which data is to be read. The AT27C1024-70JU supports 17 address lines.

- Data Outputs (O0-O7): These are the output pins that provide the 8-bit data stored in the memory location addressed by the address inputs.

- Chip Enable (CE): This active low input enables the chip to be accessed. When high, it puts the device into a low-power standby mode.

- Output Enable (OE): This is an active low input that enables the data output buffers. It controls the output of data on the data pins.

- Program Supply Voltage (VPP): Used during programming, but not applicable for the OTP version as it is only programmed once during manufacturing.

- Power Supply (VCC): The pin used to provide the necessary operating voltage to the device.

- Ground (GND): The common ground reference for the device.
