Intel TD27C256-25 is a 262144-bit (32K x 8) CMOS Ultraviolet Erasable Programmable Read-Only Memory (UVPROM). This asynchronous device offers a maximum access time of 250ns, making it suitable for high-performance applications. The TD27C256 series UVPROM utilizes a 32kx8 memory organization and operates with a nominal supply voltage of 5V. Its 28-terminal Ceramic Dual In-line Package (CDIP28) with through-hole mounting and 2.54mm terminal pitch facilitates robust integration into existing designs. Key features include 3-state outputs for bus compatibility, a programming voltage of 12.75V, and a maximum supply current of 30mA. Operating across a temperature range of -40°C to +85°C, this component finds application in industrial control, data logging, and legacy system upgrades.
