Additional Details

The GT25C128A-2GLI-TR utilizes a 4-wire SPI interface consisting of serial clock (SCK), serial data input (SI), serial data output (SO), and chip select (CS). The device supports standard SPI modes (0,0) and (1,1). It features a self-timed write cycle with automatic erase before write. The write cycle typically takes a few milliseconds. The device is typically available in SOIC-8, TSSOP-8 and other small outline packages. The operating temperature range is typically -40°C to +85°C. The 2GLI indicates specific packaging and lead-free compliance details, while TR often denotes tape and reel packaging for automated assembly.
