AT27C512R-70PU

The AT27C512R-70PU is a high-performance, low-power, 512-Kilobit One-Time Programmable (OTP) Read-Only Memory (EPROM) integrated circuit. Manufactured by Microchip Technology, this chip features a storage capacity of 64K x 8 bits, making it suitable for storing firmware and software that do not require updates. The "70PU" designation indicates a 70-nanosecond access time, allowing for quick data retrieval, and the device comes in a 28-pin plastic dual in-line package (PDIP).
Key features of the AT27C512R-70PU include its high-speed performance, low power consumption, and high-reliability storage. The device operates at a voltage range of 4.5V to 5.5V, making it compatible with most standard microprocessor systems. It is designed for use in automotive, industrial, and consumer electronics applications where non-volatile storage is critical. The robustness of the AT27C512R-70PU ensures data retention for up to 100 years with a high level of endurance. However, being OTP EPROM means it cannot be electrically erased or reprogrammed once written, necessitating precision during programming.

The AT27C512R-70PU is a 512-Kb (kilobit) one-time programmable (OTP) read-only memory (ROM) integrated circuit. It comes in a 28-pin dual in-line package (DIP). Here is a brief overview of its pin count and functions:
- Pins 1-15 and 17-19, 21: These are address pins (A0-A14). They are used to select the address of the memory location to be read.
- Pins 9, 22: These are data output pins (Q0-Q7). They output the data stored at the selected address.
- Pin 20: Chip Enable (CE). This pin must be low for the device to be active.
- Pin 22: Output Enable (OE). This pin must be low to enable the data output buffers and read data.
- Pin 28: VCC. This is the power supply pin.
- Pin 14: Ground (GND). This is the ground pin.
This configuration enables the device to output 8 bits of data for each address within the 64KB memory space. It’s suitable for applications where reliable, non-volatile storage of firmware or other small programs is needed.
