Microchip Technology's 27HC291 series OTP ROM, part number 27HC291-55-L, offers a 2K x 8 memory organization with a maximum access time of 55ns. This CMOS component operates asynchronously and features common I/O with 3-state output characteristics. Designed for surface mounting, it is housed in a 28-lead PQCC package (JESD-30 Code S-PQCC-J28). The device supports a supply voltage range of 4.5V to 5.5V with a nominal 5V operation and requires a programming voltage of 12.75V. Typical applications for this non-volatile memory include industrial control, consumer electronics, and embedded systems requiring fixed program storage. The operating temperature range is 0°C to 70°C.
