IS25LP128F-JKLE

IS25LP128F-JKLE is a 128-Mbit serial NOR flash memory from ISSI. It uses a SPI‑compatible serial interface (standard SPI with optional Dual/Quad I/O modes) to store firmware and data non‑volatily. Capacity is 16 MB. Operating voltage is 2.7–3.6 V; industrial temperature range (-40 to 85 °C); available in an 8‑pin JKLE RoHS package. Key features: fast read up to ~104 MHz, 256‑byte page programs, 4 KB sectors, 64 KB and 256 KB blocks, chip erase option, deep power‑down, and hardware protection/security features. Endurance is typically around 100k P/E cycles with long data retention. Common applications include firmware/boot memory for microcontrollers and embedded systems, code storage, and data logging. For exact timing, opcodes, and pinout, consult the ISSI IS25LP128F‑JKLE datasheet.
