The Microchip Technology 27HC641-70I-L is an 8K x 8 CMOS One-Time Programmable (OTP) Read-Only Memory (ROM) with a maximum access time of 70ns. This component utilizes a parallel interface and features a 3-state output characteristic. Designed for operation within an industrial temperature range of -40°C to +85°C, it operates from a supply voltage of 4.5V to 5.5V. The 27HC641 series memory is packaged in a 28-terminal PQCC (Plastic Quad Flat Pack) with a square body. Its high-speed access and reliable CMOS technology make it suitable for applications in industrial control systems, consumer electronics, and data storage solutions requiring non-volatile code or data storage. The device offers a memory density of 65536 bits, organized as 8192 words of 8 bits each.
