The Advanced Micro Devices AM27256-20DIB is a 32K x 8 bit, Non-Volatile One-Time Programmable Read-Only Memory (OTP ROM). This NMOS technology device offers an access time of 200 ns, suitable for applications requiring fast data retrieval. The memory organization of 32,768 words by 8 bits provides a total density of 262,144 bits. Operating asynchronously, it features 3-state outputs for flexible bus interfacing. The component is housed in a 28-lead ceramic dual in-line package (CDIP) with through-hole termination, designed for robust integration into legacy and industrial systems. Typical applications include firmware storage, control systems, and embedded processing across industrial automation, telecommunications, and consumer electronics sectors. The device operates over a temperature range of -40°C to 85°C and requires a supply voltage of 5V nominal.
