The MT25QL128ABA8E12-1SIT from Micron is a 128Mb serial NOR flash with Quad I/O SPI operating at 133MHz, providing fast read throughput for firmware storage and execute-in-place applications.
The MT25QL128ABA8E12-1SIT is a 128Mb (16MB) SPI NOR Flash from Micron in SOIC-16 (208mil width), supporting standard SPI, Dual I/O, and Quad I/O (QIO) modes. The 16-pin SOIC-16 package provides separate pins for WP (IO2) and HOLD (IO3), which can be repurposed as data lines in QIO mode, enabling 4-bit parallel data transfer. In QIO mode at 133MHz SDR clock, the bandwidth is 66MB/s (133MHz x 4 bits); in QIO DDR mode, 266MB/s. The Flash memory is organized as 256 sectors of 64KB each, with 4096 sub-sectors of 4KB for flexible erase granularity. The 4KB sub-sector erase takes 0.3s, while a 64KB sector erase takes 1.5s. Page programming writes 1-256 bytes in 0.5ms typical. The device supports XIP (eXecute In Place): the host MCU can directly execute code from the Flash without copying to RAM, using the QIO mode for sufficient bandwidth. The QE (Quad Enable) bit in the status register must be set before using IO2/IO3 as data lines. The device includes 3 x 256-byte security registers with 64-bit unique IDs for anti-counterfeiting. The 4KB parameter sectors at the top or bottom of the address space support boot code storage. The -1SIT suffix specifies: 133MHz, SOIC-16, industrial temperature (-40C to +85C). The device is used for: bootloader storage, firmware images, FPGA configuration, and XIP code storage in embedded Linux systems.
