The Texas Instruments TMS27C256-12JE is a 32K x 8 bit CMOS UV Erasable Programmable Read-Only Memory (UVPROM). This asynchronous device offers a maximum access time of 120 ns, facilitating efficient data retrieval in demanding applications. Its organization of 32,768 words by 8 bits is housed within a 28-lead ceramic dual in-line package (CDIP), suitable for through-hole mounting. The TMS27C256 series operates with a supply voltage range of 4.5V to 5.5V, with a nominal 5V requirement, and features a standby current of 250 µA and an active supply current of 30 mA. This component finds utility in industrial automation, telecommunications infrastructure, and legacy system designs where non-volatile code storage is critical. It requires a programming voltage of 13V for data inscription.
