Product details
Overview
W63AH6NBVACE 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 HSUL_12 I/O interface mode; used as main memory in mobile SoC platforms requiring low-power, high-bandwidth DRAM.
For engineers reviewing the W63AH6NBVACE datasheet, W63AH6NBVACE pinout, W63AH6NBVACE application, or W63AH6NBVACE equivalent, key selection criteria include LPDDR3 JEDEC compliance, HSUL_12 signaling, on-die termination (ODT), partial array self-refresh (PASR), and CA training support for system-level timing calibration.
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 deep power-down modes.
Internal operation includes programmable mode registers (MR0–MR63) for configuration of ODT states, PASR masking, temperature-sensing, DQ/CA calibration, and ZQ calibration; all controlled via MRW/MRR commands synchronized to CK.

FAQ
What is the maximum data rate supported by W63AH6NBVACE?
W63AH6NBVACE supports up to 1066 MT/s (megatransfers per second), corresponding to a 533 MHz clock frequency with double-data-rate operation. This performance level meets JEDEC LPDDR3 specification requirements for high-end mobile processors and is validated under VDDQ = 1.2V, tCK = 1.875 ns, and commercial temperature conditions.
Does W63AH6NBVACE support partial array self-refresh (PASR)?
Yes, W63AH6NBVACE supports PASR via MR16 (bank mask) and MR17 (segment mask) registers, allowing selective refresh of active memory regions. This feature reduces self-refresh current significantly-down to IDD6 levels-extending battery life in always-on mobile and IoT applications without compromising data retention integrity.
What package type and dimensions does W63AH6NBVACE use?
W63AH6NBVACE uses a 136-ball Fine-Pitch Ball Grid Array (FBGA) package per JEDEC MO-271AA, measuring 9.0 mm × 11.5 mm × 0.8 mm with 0.5 mm ball pitch. The ball map follows standard LPDDR3 pinout including dedicated CA, DQ, DQS, CK, and control signals, ensuring compatibility with common mobile PCB stackups.
How is on-die termination (ODT) configured on W63AH6NBVACE?
ODT on W63AH6NBVACE is configured through MR11 (ODT Control) and MR2 (Device Feature 2) registers, supporting Rtt_Nom (60 Ω), Rtt_WR (30 Ω), and Rtt_Park (120 Ω) states. These settings are dynamically selectable per command cycle to optimize signal integrity during reads, writes, and idle periods without external resistors.
Is CA training supported by W63AH6NBVACE, and how is it implemented?
Yes, W63AH6NBVACE supports CA training via MR41, MR42, and MR48 registers to calibrate command/address timing skew. The process uses internal pattern generation and sampling logic to adjust delay taps on CA lines, ensuring setup/hold compliance across temperature, voltage, and PCB trace length variations-critical for reliable boot and high-speed initialization.
