Product details
Overview
W63AH6NBVACI TR from Winbond is a 1Gb (128MB) LPDDR3 SDRAM with x32 data bus width, 1.2V VDDQ supply, and 8-bank architecture supporting up to 1066 MT/s data rates. It operates across -40°C to +85°C industrial temperature range and implements on-die termination (ODT), partial array self-refresh (PASR), and CA training for high-speed mobile memory subsystems in application processors and SoCs.
For engineers reviewing the W63AH6NBVACI TR datasheet, W63AH6NBVACI TR pinout, W63AH6NBVACI TR application, or W63AH6NBVACI TR equivalent, key selection criteria include LPDDR3-1066 timing compliance, x32 interface support, industrial-grade thermal operation, and ZQ calibration capability for signal integrity in compact mobile and embedded designs.
Technical Context
This device implements JEDEC-standard LPDDR3 protocol with dual-edge command/address bus, 10-bit CA bus multiplexing, and HSUL_12 I/O interface. It supports burst lengths of 8 and 16, auto-precharge, and deep power-down modes with tCK = 1.875 ns (533 MHz clock).
Functional features include MRW-controlled ODT states, PASR bank/segment masking via MR16/MR17, CA training across MR41–MR42–MR48, and temperature-sensing via MR4 readback. Power management relies on CKE gating, self-refresh, and controlled power-off sequencing per JEDEC JESD209-3B.

Pinout & Package
W63AH6NBVACI TR uses a 134-ball FBGA package (10.5 mm × 13.0 mm × 0.8 mm height) with 0.5 mm ball pitch and RoHS-compliant matte tin finish. Ball assignment follows JEDEC-standard LPDDR3 layout with dedicated VDD/VSS groups, differential clocks (CK_t/CK_c), strobes (DQS_t/DQS_c), and CA bus (CA[9:0]).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CK_t / CK_c | Differential clock input | HSUL_12 differential pair referenced to VDDQ; defines all timing windows (tCK = 1.875 ns min) |
| DQS_t / DQS_c | Differential data strobe | Source-synchronous capture aid for DQ[31:0]; supports write leveling and read deskew |
| CA[9:0] | Multiplexed command/address bus | 10-bit double-data-rate bus carrying commands (ACT, PRE, REF), row/column addresses, and bank selects |
| DQ[31:0] | Data I/O lines | x32 bidirectional data bus using HSUL_12 drivers; supports burst lengths of 8 or 16 |
| DM[3:0] | Data mask inputs | Byte-level write masking for DQ[31:0] - each DM bit masks 8 consecutive DQ bits |
| CKE | Command clock enable | Asynchronous active-high input controlling entry/exit from power-down and self-refresh modes |
| ZQ | Calibration reference pin | Connects to 240 Ω ±1 % external resistor for RONPU/RONPD and ODT impedance calibration |
Key Features
| Feature | Design Value |
|---|---|
| On-Die Termination (ODT) | Programmable ODT levels (Rtt_Nom = 34 Ω, 48 Ω, 60 Ω, 120 Ω, 240 Ω) via MR11 - eliminates external termination resistors and improves signal integrity |
| Partial Array Self-Refresh (PASR) | Configurable bank- or segment-level refresh via MR16/MR17 - cuts self-refresh current by up to 75% when only portions of memory are active |
| CA Training | Three-phase training sequence (MR41 → MR42 → MR48) - compensates for CA bus skew and ensures reliable command decoding at 533 MHz |
| ZQ Calibration | One-time or periodic calibration of output driver strength and ODT resistance using external 240 Ω resistor - maintains impedance accuracy over voltage/temperature |
| Temperature Sensor | Integrated sensor readable via MR4 - enables dynamic refresh rate adjustment (tREFI scaling) based on real-time die 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 WT:A | Same density (1Gb x32), but rated for -25°C to +85°C; uses different CA training flow and lacks MR4 temperature readback | Targeted at consumer tablets; not qualified for extended industrial temperature cycling | Select when cost sensitivity outweighs need for full industrial temp range and integrated thermal sensing |
| IS43TR16128C-125KBL | 1Gb x16 configuration only; supports LPDDR3-1200 (tCK = 1.667 ns); requires separate x2 stacking for x32 equivalent bandwidth | Requires board redesign for x32 interface; higher peak bandwidth but increased layout complexity and power | Choose only if system demands >9.6 GB/s bandwidth and can accommodate dual-die routing and thermal management |
Compared with MT52L1G32D2PF-107 WT:A and IS43TR16128C-125KBL, W63AH6NBVACI TR uniquely combines industrial temperature qualification, integrated temperature sensing, and native x32 interface in a single 134-ball FBGA - simplifying layout, reducing BOM count, and enabling adaptive power management without external sensors.

FAQ
What is the maximum supported data rate for W63AH6NBVACI TR?
W63AH6NBVACI TR supports LPDDR3-1066 operation with a minimum clock period (tCK) of 1.875 ns, delivering a maximum data rate of 1066 MT/s. This is validated across the full industrial temperature range (-40°C to +85°C) and requires strict adherence to JEDEC JESD209-3B AC timing parameters including tRCD, tRP, and tRAS.
Does W63AH6NBVACI TR support on-die termination (ODT)?
Yes, W63AH6NBVACI TR supports programmable on-die termination via MR11, offering selectable Rtt_Nom values of 34 Ω, 48 Ω, 60 Ω, 120 Ω, and 240 Ω. This eliminates the need for external termination resistors on DQ and DQS lines and improves signal integrity in high-speed layouts.
How does W63AH6NBVACI TR implement partial array self-refresh (PASR)?
W63AH6NBVACI TR implements PASR through MR16 (bank mask) and MR17 (segment mask), allowing selective refresh of active memory regions only. This reduces self-refresh current significantly - down to ~25% of full-array refresh - while maintaining data retention in targeted banks or segments.
Is CA training required for reliable operation of W63AH6NBVACI TR?
Yes, CA training is mandatory for stable operation at 533 MHz. W63AH6NBVACI TR performs three-phase CA training using MR41, MR42, and MR48 to calibrate command/address timing margins and compensate for interconnect skew, ensuring robust command decoding in dense mobile PCB layouts.
What is the purpose of the ZQ pin on W63AH6NBVACI TR?
The ZQ pin on W63AH6NBVACI TR connects to an external 240 Ω ±1% precision resistor and serves as the reference for ZQ calibration. This process adjusts internal output driver (RONPU/RONPD) and ODT resistance values to maintain impedance accuracy across voltage and temperature variations, critical for signal integrity at 1066 MT/s.
