Texas Instruments TMS27C256-120JE4 is a 32K x 8 bit (262,144 bit) CMOS UV Erasable Programmable Read-Only Memory (UVPROM). This asynchronous memory device features a maximum access time of 120 ns and operates from a 5V supply voltage. The TMS27C256 series utilizes a CMOS technology for low power consumption, with a standby current of 250 µA maximum. It is packaged in a 28-pin Ceramic Dual In-line Package (CDIP) with a glass-sealed window for UV erasure, suitable for through-hole mounting. This component is well-suited for applications in industrial control, data logging, and legacy system upgrades where non-volatile program storage is required. The device supports a programming voltage of 13V and operates within an industrial temperature range of -40°C to +85°C.
