The Microchip Technology 27HC64-40-L is an 8K x 8 One-Time Programmable (OTP) Read-Only Memory (ROM) device. This CMOS component offers a maximum access time of 40ns, ensuring efficient data retrieval. It features a parallel interface and 3-state outputs, with a common I/O type. The memory organization consists of 8,192 words, each 8 bits wide, yielding a total memory density of 65,536 bits.
Designed for surface mounting, the 27HC64-40-L is housed in a 32-terminal PQCC (Plastic Leaded Chip Carrier) package with a terminal pitch of 1.27mm, conforming to the R-PQCC-J32 standard. It operates asynchronously within a temperature range of 0°C to 70°C and requires a supply voltage between 4.5V and 5.5V, with a nominal voltage of 5V. Typical applications for this type of memory include embedded systems, industrial control, and consumer electronics where fixed program storage is required. The programming voltage is 12.5V.
