Product details
Overview
W63AH2NBVADE from Winbond is a 1Gb (128MB) LPDDR3 SDRAM with x16 data bus, 1.2V VDDQ supply, 8-bank architecture, and support for 800–1066 MT/s data rates in mobile and embedded applications requiring low-power, high-bandwidth memory.
For engineers reviewing the W63AH2NBVADE datasheet, W63AH2NBVADE pinout, W63AH2NBVADE application, or W63AH2NBVADE equivalent, key selection criteria include LPDDR3 JEDEC compliance, on-die termination (ODT), partial array self-refresh (PASR), CA training capability, and HSUL_12 I/O interface timing.
Technical Context
This device implements JEDEC-standard LPDDR3 protocol with dual-edge command/address transfer on a 10-bit CA bus, enabling reduced pin count versus DDR3. It supports burst lengths of 8 and 16, auto-precharge, and programmable mode registers for configuration of ODT, PASR, calibration, and temperature sensing.
Power management includes deep power-down, self-refresh, and power-down modes with controlled entry/exit sequences. Timing control relies on CK/CK# differential clocks and DQS/DQS# strobes, with ZQ calibration for output driver and ODT resistance tuning across voltage and temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LPDDR3 memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MT52L1G32D2PF-107 | 1Gb x32 LPDDR3, 1066 MT/s, same VDDQ range, but larger 144-ball VFBGA package | Requires board redesign due to different ball count, pitch, and x32 interface; higher bandwidth but lower density efficiency | Select when system memory controller supports x32 and board layout allows larger footprint |
| K4E6E304EC-EGCF | 1Gb x16 LPDDR3, 1066 MT/s, identical 134-ball VFBGA, but Samsung-specific CA training implementation | Same mechanical fit and electrical interface; minor MR register mapping differences require firmware adaptation | Choose for drop-in replacement where existing Samsung ecosystem tooling and initialization code are already validated |
Compared with MT52L1G32D2PF-107 and K4E6E304EC-EGCF, W63AH2NBVADE offers identical x16 134-ball form factor and JEDEC LPDDR3 compliance, but with Winbond's optimized PASR granularity and simplified MR10/MR11 ODT control-making it ideal for space-constrained, thermally sensitive mobile designs.

FAQ
What is the operating voltage range for W63AH2NBVADE?
W63AH2NBVADE operates with VDD1 at 1.7–1.95 V for core logic and VDD2/VDDCA/VDDQ at 1.14–1.30 V for I/O and command/address circuits. This dual-voltage architecture enables power optimization across functional domains while maintaining JEDEC LPDDR3 compatibility. The specified ranges are validated across temperature and process corners per the Dec. 2019 datasheet revision A01-003.
Does W63AH2NBVADE support on-die termination (ODT)?
Yes, W63AH2NBVADE supports programmable on-die termination through MR11 (MA[7:0] = 0BH), allowing dynamic configuration of ODT resistance values for DQ and DQS lines during reads, writes, and power states. This eliminates the need for external termination resistors and improves signal integrity on high-speed memory interfaces.
What package type and dimensions does W63AH2NBVADE use?
W63AH2NBVADE uses a 134-ball Very Fine Pitch Ball Grid Array (VFBGA) package measuring 9 mm × 12 mm × 0.8 mm with 0.5 mm ball pitch. The ball assignment follows JEDEC MO-245AC and is documented in Section 4 ("Ball Assignment") of the official datasheet.
How does W63AH2NBVADE implement partial array self-refresh (PASR)?
W63AH2NBVADE implements PASR via MR16 (bank masking) and MR17 (segment masking), allowing selective refresh of only active memory regions. This reduces IDD6 current by up to 75% compared to full-array self-refresh, directly extending battery runtime in mobile standby modes without compromising data retention.
Is CA training supported on W63AH2NBVADE?
Yes, W63AH2NBVADE supports CA training through MR41–MR43 (MA[7:0] = 29H–2BH), enabling automatic delay calibration of the 10-bit command/address bus to compensate for inter-symbol skew and PCB trace mismatch at 1066 MT/s operation.
