IS43TR16256BL-107MBL

IS43TR16256BL-107MBL is an ISSI memory IC (IS43TR16256BL family). It is a high-density DRAM device intended for embedded/mobile systems. The “16256” denotes a 16‑Mbit class part, commonly organized as 2M×8 or 1M×16 depending on the internal configuration, and it requires periodic automatic refresh. The “107” typically signals a maximum operating frequency around 107 MHz. The suffix “BL/MBL” indicates a specific RoHS Pb-free package/voltage tier for low‑power operation. It uses a parallel data interface and supports standard DRAM features such as row/column addressing and auto‑refresh across multiple banks. It’s suited for system memory in portable electronics, set‑top boxes, and similar applications. For exact organization (2M×8 vs 1M×16), supply voltage, timing parameters, and packaging options, consult the official ISSI datasheet.

Pin count: 32 pins (in the standard package for this device).
Function: IS43TR16256BL-107MBL is a synchronous DRAM device with a wide data bus (x16). It uses RAS/CAS-style addressing and operates at up to 107 MHz.

- Manufacturer: Integrated Silicon Solution, Inc. (ISSI).
- What kind of company: A fabless semiconductor company that designs memory products (DRAM and SRAM) and markets memory ICs; manufacturing is done through external foundries.

IS43TR16256BL-107MBL is a dynamic RAM device used as fast memory in various systems. Typical application areas include:
- Embedded systems and SoC/microprocessor-based designs as main memory
