MX77U25650FZ4I42

MX77U25650FZ4I42 is a Macronix MX77U family serial non-volatile memory device. It’s designed for embedded systems to store firmware and data. The “25650” typically indicates a high-density memory (hundreds of megabits) accessed over a serial interface (SPI) with standard operations such as read, program/erase, and sector protection. It operates at low voltage (roughly 1.65–3.6V) and offers fast access speeds plus security features like hardware write protection and a device ID. The “FZ4I42” suffix encodes packaging, temperature range, and voltage options. For exact electrical specs, timing, endurance, package type, and feature set, refer to the official Macronix datasheet.

Pin count: 42 pins (I42 package).
