The Intel P27C256-20 is a 32K x 8-bit (256 Kbit) One-Time Programmable (OTP) Read-Only Memory (ROM) utilizing advanced CMOS technology. This component offers a maximum access time of 35ns, ensuring high-speed data retrieval. Its memory organization is 512K x 8, with a density of 4096 Kbits. The P27C256-20 operates asynchronously and features 3-state outputs. It is housed in a 28-lead plastic dual in-line package (PDIP), specifically a R-PDIP-T28, with through-hole mounting and a terminal pitch of 2.54mm. This device is suitable for applications requiring non-volatile program storage in industrial and consumer electronics. The standby current is a maximum of 100 µA, and the supply current is 170mA at a nominal supply voltage of 5V. Programming requires a voltage of 12.75V.
