IS43DR16128B-3DBLI

IS43DR16128B-3DBLI is an ISSI (Integrated Silicon Solutions, Inc.) 128-kbit dynamic RAM (DRAM) device. It is organized as 16,384 words × 8 bits (16K × 8), suitable for small on-board memory needs in embedded electronics.
Key points:
- Type/organization: DRAM, 16K × 8 (128 kbit total).
- Interface: multiplexed address inputs with RAS/CAS control; asynchronous DRAM operation.
- Refresh: requires periodic row/column refresh to retain data.
- Voltage: typically operates from a 3.0 V–3.6 V supply (3.3 V family common in many ISSI parts).
- Speed/package suffix: “-3” denotes a speed grade; “DBLI” indicates packaging and RoHS lead-free (UL/IBL) status; exact package type and mechanical details in the datasheet.
- Applications: small buffers and memory arrays in consumer electronics, embedded systems, and similar low-to-mid capacity DRAM requirements.
For precise electrical specs (tRC, tRAS, tCAS, current, pinout) and recommended operating conditions, consult the official IS43DR16128B-3DBLI datasheet.

IS43DR16128B-3DBLI is a 128-Mbit DRAM (16M × 8) in TSOP-II, 3.3V, with -3 timing. Equivalents are other 128-Mbit (16M × 8) DRAMs from Micron, Samsung, Hynix, Nanya, etc., in the same package and voltage. For exact cross-reference, please provide the package (e.g., TSOP-II 54/60-pin) and timing/speed (-3). I can then list precise replacement part numbers.
