Microchip Technology's 27HC64 series OTP ROM, part number 27HC64-70I-P, offers an 8K x 8 memory organization with a maximum access time of 70ns. This CMOS device features asynchronous operation and 3-state outputs, suitable for applications requiring non-volatile program storage. The component operates within a temperature range of -40°C to +85°C and utilizes a 5V nominal supply voltage. Packaged in a 28-lead PDIP (Plastic Dual In-line Package) with through-hole mounting, this device supports a programming voltage of 12.5V. Common applications include industrial control systems, legacy system upgrades, and embedded solutions where fixed program memory is essential. The dual in-line package format and parallel interface simplify integration into existing board designs.
