The Microchip Technology 27HC256-70E-L is a 262,144-bit (32K x 8) CMOS One-Time Programmable (OTP) ROM. Featuring a maximum access time of 70ns, this component operates asynchronously with a 5V nominal supply voltage, ranging from 4.5V to 5.5V. The memory organization is 32K words by 8 bits, utilizing common I/O. This device is packaged in a 32-lead PQCC (Plastic Chip Carrier) with J-bend terminals, suitable for surface mounting. The 27HC256 series is designed for applications requiring reliable, non-volatile program storage, commonly found in industrial control systems, telecommunications equipment, and consumer electronics where firmware or configuration data needs to be permanently stored. Its 3-state outputs offer flexibility in bus interfacing. The operating temperature range is -40°C to +125°C.
