Microchip Technology's 27HC641-70-L is an 8K x 8 One-Time Programmable (OTP) Read-Only Memory (ROM) device. This CMOS component offers a maximum access time of 70ns, facilitating high-speed data retrieval. The memory organization is 8K words by 8 bits, providing a total density of 65536 bits. Operating asynchronously, it features 3-state outputs and common I/O. The 27HC641 series device is housed in a 28-lead PQCC (Plastic Chip Carrier) package, designed for surface mounting with a terminal pitch of 1.27mm. This component finds application in embedded systems, consumer electronics, and industrial control where reliable, non-volatile program storage is required. It operates within a supply voltage range of 4.5V to 5.5V.
