Intel AD87C257-170V10 is a 32K x 8 bit UV Erasable Programmable Read-Only Memory (UVPROM) device within the AD87C257 series. This CMOS component offers a maximum access time of 170ns and operates asynchronously with a 5V nominal supply voltage. Featuring 3-state outputs, it utilizes common I/O and is housed in a 28-terminal Ceramic Dual In-line Package (CDIP28) with through-hole mounting. The device operates across a temperature range of -40°C to 125°C. Its robust design and specifications make it suitable for applications in industrial control, telecommunications, and legacy system upgrades where reliable non-volatile storage is critical. The memory organization is 32K words by 8 bits, providing a total density of 262,144 bits. Standby current is specified at a maximum of 0.1mA, with a maximum operating supply current of 30mA.
