Winbond Electronics Corporation W63AH2NBVADE TR

Overview

W63AH2NBVADE TR from Winbond is a 1Gb (128MB) LPDDR3 SDRAM with x16 data bus, 1.2V VDDQ supply, and 8-bank architecture, supporting up to 1066 MT/s data rates in high-efficiency mobile and embedded memory subsystems. It implements on-die termination (ODT), partial array self-refresh (PASR), and CA training for signal integrity in space-constrained SoC interfaces.

For engineers reviewing the W63AH2NBVADE TR datasheet, W63AH2NBVADE TR pinout, W63AH2NBVADE TR application, or W63AH2NBVADE TR equivalent, this page delivers verified LPDDR3 timing compliance, ball assignment mapping, voltage domain partitioning (VDD1/VDD2/VDDCA/VDDQ), and mode register configuration details essential for DDR controller initialization and layout validation.

Technical Context

This device operates as a double-data-rate synchronous DRAM with command/address bus multiplexing across 10 pins, using both clock edges for command transfer. It supports burst lengths of 8 and 16, auto-precharge, and refresh scheduling compliant with JEDEC JESD209-3B.

Power management includes deep power-down, self-refresh, and PASR with bank/segment masking via MR16/MR17. Calibration features include ZQ, DQ pattern A/B (MR32/MR40), and CA training (MR41–MR42, MR48) to maintain signal integrity at 533 MHz clock frequency (tCK = 1.876 ns).

Key Specifications

Pinout & Package

FAQ

What is the ball count and package type of W63AH2NBVADE TR?

W63AH2NBVADE TR uses a 134-ball Very Fine Pitch Ball Grid Array (VFBGA) package with 0.5 mm pitch and 9 mm × 12 mm body dimensions. This package is optimized for high-density mobile PCBs and supports automated optical inspection and reflow soldering per IPC-7351B standards. The ball map is fully documented in Section 4 ("Ball Assignment") of the official Winbond datasheet revision A01-005.

Does W63AH2NBVADE TR support write leveling?

W63AH2NBVADE TR does not implement write leveling as a built-in hardware function. Instead, it supports CA training (via MR41, MR42, MR48) and DQ calibration (MR32, MR40) to align command/address timing and data eye positioning. Write-leveling functionality must be handled externally by the memory controller, which uses DQS-to-CK phase adjustment based on feedback from these calibration registers.

What are the key differences between W63AH2NBVADE TR and W63AH6NB?

W63AH2NBVADE TR and W63AH6NB share identical architecture, timing, and electrical specifications, differing only in data bus width: W63AH2NBVADE TR is x16, while W63AH6NB is x32. Both use the same 134-ball VFBGA package but with distinct ball assignments for DQ[31:16] in the x32 variant. No other functional or parametric differences exist between the two part numbers.

Is W63AH2NBVADE TR qualified for automotive AEC-Q200 stress testing?

W63AH2NBVADE TR is not AEC-Q200 qualified. It is rated for industrial temperature range (–25°C to +85°C) and intended for consumer, industrial, and medical applications. For automotive use, Winbond offers separate AEC-Q200–qualified LPDDR3 variants with extended temperature screening and additional reliability testing - W63AH2NBVADE TR itself does not carry that qualification.

How is refresh managed in W63AH2NBVADE TR during self-refresh mode?

In self-refresh mode, W63AH2NBVADE TR autonomously executes internal refresh cycles using an on-chip timer, requiring only CKE held low and stable VDD/VDDQ. The device maintains data integrity for up to 7.8 µs per row at 85°C without external refresh commands. Exit from self-refresh is initiated by driving CKE high, followed by a tRFC delay before issuing new commands - all timing values are specified in Section 8.7 of the datasheet.
