概要

Description

IS43TR16640BL-107MBL is a DRAM device from ISSI (IS43TR series). It is a small, high-density dynamic RAM organized as 16K × 4 (roughly 8 KB per die) with a DRAM-style interface. The memory uses multiplexed addresses and requires periodic refresh (RAS/CAS/WE/CE control typical of DRAMs). The “40” in the part name usually denotes a speed grade (e.g., around 40 ns access time), while “BL” indicates a packaging/lead-finish variant and “107MBL” denotes a specific production/lot variant. It’s intended for embedded and consumer electronics where compact RAM is needed.
Note: exact electrical specs (supply voltage, timing parameters, refresh interval, package type) vary by lot and packaging. For precise operating conditions and timing diagrams, consult the latest ISSI datasheet or a distributor’s datasheet entry.

Features

I don’t have the exact datasheet on hand. IS43TR16640BL-107MBL is an ISSI memory device, and its exact specs (capacity, timing, voltage) depend on the revision. Likely features (typical for this family) include:
- 16M-word x 40-bit organization (32-bit data path + 8-bit ECC)
- ECC-enabled data path for error detection/correction
- Synchronous DRAM interface with clocked operation and burst access
- Multi-bank architecture with auto/self-refresh
- 3.3V supply (with possible variants) and low-power standby
- Standard control signals: CK, CKE, CS, RAS, CAS, WE
- Pb-free package options and industrial temperature variants
For precise specifications (capacity, CAS latency, burst length, voltage, timing parameters, and package), please share the datasheet link or confirm the exact variant, and I’ll summarize the exact features.

Package

Ball Grid Array (BGA) package, specifically the FBGA-style variant.

Pinout

Pin count and function depend on the package, but the common IS43TR16640BL-107MBL part is a 54‑pin TSOP II SDRAM. It is a 3.3V, 16‑bit wide synchronous DRAM. Typical pinout includes: CLK, CS, RAS, CAS, WE, A0–A12, BA0–BA1, DQ0–DQ15, DQM0/DQM1.

Manufacturer

- Manufacturer: Integrated Silicon Solution, Inc. (ISSI)
- What kind of company: A fabless semiconductor company that designs and markets memory products (DRAM, SRAM) and mixed-signal ICs.

Application

IS43TR16640BL-107MBL is a synchronous DRAM used as system memory. Typical application areas: embedded systems and microprocessor boards; consumer electronics (set-top boxes, TVs, DVD players) for buffers and caches; networking/telecom equipment (routers, switches, modems) as main memory; printers and office equipment buffers; industrial control and instrumentation; automotive infotainment (with automotive-grade variants).
