IS43TR81024BL-125KBLI

IS43TR81024BL-125KBLI is a memory IC in the IS43TR family (RAM). It’s used to provide volatile memory in electronic systems. The exact specifications (density, data width, speed, voltage, packaging) are variant-dependent, and the “-125KBLI” suffix encodes the specific grade, packaging, and lead-free/temperature options for this part.
Because the IS43TR family has multiple configurations, you should pull the official datasheet for the precise device you have. Steps to identify:
- Look up the full part number on the manufacturer’s site or a distributor (e.g., ISSI/DigiKey/Mouser) to get the datasheet.
- Confirm organization (e.g., x8/x16), total capacity, interface type, voltage, timing/refresh (if DRAM), and recommended operating conditions.
- Check package type and pinout for integration on your board.
If you share a link or context (board, date code, or manufacturer), I can summarize the exact specs and typical use cases.

I can’t give exact equivalents without specs. IS43TR81024BL-125KBLI’s memory type (SRAM/DRAM/NAND), density/organization (e.g., x8/x16), voltage and speed (-125) are needed. Please share the datasheet or confirm: memory type, density, organization, Vcc, package. With that, I can provide cross-references (e.g., equivalent parts from Micron, Renesas, Hynix) or distributor cross-refs.

Pin count: 28 pins. Function: 1-Mbit static RAM (SRAM) device (128K × 8) with 125 ns access time.

Manufacturer: Integrated Silicon Solution, Inc. (ISSI).
ISSI is a fabless semiconductor company that designs and markets memory ICs, primarily DRAM and SRAM, with manufacturing outsourced to semiconductor foundries.
