AS4C128M16D3LB-12BIN

Do you want exact cross-reference numbers? If yes, specify preferred vendors (e.g., Samsung, Hynix, Micron) or region. Otherwise, equivalence is: 2Gb (256MB) DDR3L SDRAM, x16, 1.35V, DDR3L-1333, -12BIN. Major vendor equivalents are 2Gb x16 DDR3L parts from Samsung, Hynix, and Micron; I can provide precise cross-references once you name suppliers.

AS4C128M16D3LB-12BIN is a DDR3L SDRAM device with the following typical features:
- Type/organization: DDR3L SDRAM, 128M × 16 (2 Gbit total) density
- Voltage: VDD/VDDQ ≈ 1.35V (DDR3L), VPP ≈ 2.5V
- Speed grade: -12BIN (board/controller dependent; generally supports DDR3L-1066/1333 MT/s)
- Architecture: 8 banks; pipelined, multi-bank operation; Burst Length 4/8
- Power/efficiency: low-voltage operation with features for power-down modes
