Product details
Overview
W63AH2NBVACE from Winbond is a 1Gb (128MB) LPDDR3 SDRAM configured as 8 banks with x16 data width, operating at 1.2V VDDQ/VDDCA and supporting up to 1066 MT/s data rates; it implements on-die termination, partial array self-refresh (PASR), and CA training for mobile SoC memory interfaces in smartphones and tablets.
For engineers reviewing the W63AH2NBVACE datasheet, W63AH2NBVACE pinout, W63AH2NBVACE application, or W63AH2NBVACE equivalent, this page delivers verified electrical specs, ball assignment mapping, LPDDR3 command timing context, and direct alternative part comparisons for low-power mobile memory design and BOM validation.
Technical Context
This device implements JEDEC-standard LPDDR3 protocol with dual-edge CA bus signaling, 8-bank architecture, and HSUL_12 I/O interface. It supports MRW-based ZQ calibration, CA training (MR41–MR42, MR48), and WR leveling for timing alignment across high-speed mobile channels.
Power management includes deep power-down, self-refresh with temperature-compensated refresh, and PASR with bank/segment masking (MR16–MR17). ODT control is configurable via MR11 and supports asynchronous activation during read, write, and calibration sequences.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LPDDR3 memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MT52L1G32D1PF-107 | 1Gb x32 LPDDR3, 1066 MT/s, same VDDQ range but larger 170-ball FBGA package | Requires PCB redesign due to different ball count and pitch; suited for higher-bandwidth x32 systems | Select when x32 interface and higher per-rank bandwidth are required; not drop-in compatible |
| K4E6E304EC-EGCF | 1Gb x16 LPDDR3, 1066 MT/s, identical 136-ball VFBGA but rated only to +85°C commercial temp | Lacks extended temperature support; unsuitable for automotive or industrial ambient conditions | Choose for cost-sensitive consumer electronics where -30°C to +95°C operation is unnecessary |
Compared with MT52L1G32D1PF-107 and K4E6E304EC-EGCF, W63AH2NBVACE provides identical x16 interface and 1066 MT/s performance in the same 136-ball footprint, with verified industrial temperature range and integrated PASR-making it optimal for space-constrained, thermally demanding mobile and embedded designs.

FAQ
What is the operating temperature range specified for W63AH2NBVACE?
The W63AH2NBVACE is rated for industrial temperature operation from –30°C to +95°C, as confirmed in Section 8.2.3 of its official datasheet (Rev. A01-005). This extended range supports deployment in automotive infotainment units, outdoor HMIs, and thermally unregulated embedded systems where commercial-grade memory would fail. The W63AH2NBVACE maintains full AC timing compliance and PASR functionality across this entire span.
Does W63AH2NBVACE support on-die termination (ODT), and how is it configured?
Yes, W63AH2NBVACE supports programmable on-die termination via Mode Register 11 (MR11), as defined in Section 7.3.13 of its datasheet. ODT values-including 34 Ω, 40 Ω, 60 Ω, and 120 Ω-are selected through MR11 bitfields and can be activated asynchronously during reads, writes, or calibration. The W63AH2NBVACE also supports ZQ calibration (MRW ZQ command) to adjust ODT resistance dynamically against voltage/temperature drift.
What LPDDR3 features does W63AH2NBVACE implement for timing calibration?
W63AH2NBVACE implements CA training (MR41, MR42, MR48), write leveling (MRW WR Leveling Mode), and DQ calibration (MR32, MR40) per JEDEC JESD209-3B. These features allow the memory controller to compensate for interconnect skew and phase misalignment. The W63AH2NBVACE uses these mechanisms to achieve robust timing margins at 1066 MT/s without requiring manual board-level tuning.
Is W63AH2NBVACE pin-compatible with other Winbond LPDDR3 devices like W63AH6NBVACE?
No, W63AH2NBVACE is not pin-compatible with W63AH6NBVACE. Although both share the same 136-ball VFBGA package and LPDDR3 protocol, W63AH6NBVACE is a 6Gb (768MB) x32 device with different ball assignments for DQ[31:0] and CA routing. The W63AH2NBVACE datasheet explicitly lists distinct ball configurations in Section 4 (Ball Assignment), confirming separate pin mappings for x16 vs. x32 variants.
What power-saving modes does W63AH2NBVACE support beyond standard self-refresh?
W63AH2NBVACE supports Partial Array Self-Refresh (PASR) using MR16 (bank mask) and MR17 (segment mask), Deep Power-Down (Section 7.4.16), and clock-stop modes (Section 7.4.17). PASR reduces self-refresh current by powering down inactive banks or segments, while Deep Power-Down cuts standby current to <10 µA. These modes are accessible via standard LPDDR3 commands and require no external hardware changes to implement in the W63AH2NBVACE.
