Microchip Technology's AT27C040-90PJ is a 4 Megabit (512K x 8) CMOS One-Time Programmable (OTP) Read-Only Memory. This asynchronous parallel interface device offers a maximum access time of 90 nanoseconds, facilitating efficient data retrieval. Operating within a temperature range of -40°C to +85°C, it requires a supply voltage between 4.5V and 5.5V. The component is housed in a 32-lead PDIP (Plastic Dual In-line Package) with a terminal pitch of 2.54mm, designed for through-hole mounting. Its robust architecture makes it suitable for applications in industrial control, consumer electronics, and automotive systems demanding reliable, non-volatile data storage.
