IS46TR16128CL-125KBLA2

IS46TR16128CL-125KBLA2 is a memory device from ISSI (Integrated Silicon Solution, Inc.) in the SRAM family. It is a parallel static RAM (SRAM) with a fast 125 ns access time, designed for high-speed data storage in embedded systems. The suffix LB/UB indicates lower/upper byte enables, enabling operation on wider data buses (e.g., x16). It uses a standard SRAM interface with address inputs, data I/O lines, and control signals such as chip enable (CE), output enable (OE), and write enable (WE). The part is offered in RoHS-compliant packages and specified for different temperature grades (commercial/industrial) depending on the variant. Typical applications include caches, buffers, frame buffers, and other fast storage in microcontrollers and SoCs. For exact pinout, operating voltage, package type, timing specs (tAA, tOEV, tCW), and temperature range, consult the official datasheet. If you’d like, I can help locate a link to the datasheet.
