The Advanced Micro Devices AM27256 is a 32K x 8-bit, 262,144-bit, one-time programmable (OTP) read-only memory (ROM) utilizing NMOS technology. This component offers an asynchronous operating mode with a maximum access time of 250ns. The memory organization is 32KX8, providing 32,768 words of 8-bit data. It features common I/O and 3-state output characteristics. The device operates within a supply voltage range of 4.75V to 5.25V, with a nominal voltage of 5V, and a maximum supply current of 100mA.
The AM27256 is packaged in a 28-lead ceramic dual in-line package (CDIP), identified by the R-GDIP-T28 code, with through-hole termination. Programming requires a voltage of 12.5V. This component is suitable for applications in industrial control, consumer electronics, and telecommunications equipment where non-volatile program storage is required. The operating temperature range is from 0°C to 70°C.
