Microchip Technology's 27HC256 series CMOS OTP ROM, part number 27HC256-55-L, offers a memory organization of 32K x 8 bits, providing a total density of 256 Kbits. This asynchronous ROM features a maximum access time of 55ns. The component utilizes a PQCC32 package with J-bend terminals, supporting surface mounting. Designed for a supply voltage range of 4.5V to 5.5V, it operates within a temperature range of 0°C to 70°C. Typical applications include embedded systems, industrial control, and legacy system designs where non-volatile program storage is required with a single-level voltage programming requirement. The 3-state output characteristic allows for bus interfacing.
