The Microchip Technology AT27C040-20JC is a 4 Megabit (512K x 8) CMOS One-Time Programmable (OTP) ROM. This component offers a maximum access time of 200 nanoseconds, making it suitable for applications requiring rapid data retrieval. It operates asynchronously with a 5V nominal supply voltage, ranging from 4.5V to 5.5V. The device features a 3-state output characteristic and a parallel interface. Packaged in a J-leaded PQCC32 (R-PQCC-J32) with a 1.27mm terminal pitch, it is designed for surface mounting. Typical applications include embedded systems, firmware storage, and data logging in industrial automation and consumer electronics. Standby current is rated at 100µA maximum, with a 25mA maximum supply current during operation. The operating temperature range is 0°C to 70°C.
