Microchip Technology’s 27HC191-55-L is a 16Kb (2K x 8) One-Time Programmable (OTP) Read-Only Memory (ROM) device. This CMOS component offers a maximum access time of 55 nanoseconds and operates from a single 5V supply. The memory organization is 2048 words by 8 bits, featuring common I/O with 3-state output characteristics. Housed in a 28-lead PQCC package, the 27HC191-55-L is suitable for surface-mount applications. This device finds utility in applications requiring fixed program storage, such as industrial control systems, consumer electronics, and data acquisition modules where reliable code execution is paramount. The asynchronous operating mode and parallel interface facilitate straightforward integration into existing designs. Static standby current is rated at 35mA, with a maximum operating supply current of 71mA.
