128 Mbit NOR Flash with SPI — what this part is for
The Micron MT25QL128ABA8E12-0SIT TR is a 128 Mbit serial NOR Flash memory organized as 16 M x 8 bits, accessed over a standard SPI bus at up to 133 MHz. It is a non-volatile storage device designed for code shadowing, firmware storage, parameter logging, and configuration data in embedded systems that need a moderate-density, fast-read serial memory. The part operates from a 2.7 V to 3.6 V supply and is specified over the industrial temperature range of -40°C to 85°C, making it suitable for factory automation, telecom infrastructure, networking equipment, and general-purpose industrial control boards. The 24-ball TBGA package (6 x 8 mm body) keeps the footprint compact for space-constrained PCB layouts.
133 MHz SPI clock — read throughput in context
The 133 MHz SPI clock rate is the maximum read speed on this device. For a single-bit SPI bus, that translates to roughly 133 Mbit/s raw throughput.
