Product details
Overview
W63CH2MBV from Winbond is a 4Gb (512MB) LPDDR3 SDRAM with x32 data bus, 1.2V VDDQ supply, and 8-bank architecture, supporting up to 1066MHz data rate (533MHz clock) for mobile application processors in smartphones and tablets.
For engineers reviewing the W63CH2MBV datasheet, W63CH2MBV pinout, W63CH2MBV application, or W63CH2MBV equivalent, key selection criteria include LPDDR3-1066 timing compliance, HSUL_12 I/O interface, on-die termination (ODT), partial array self-refresh (PASR), and ZQ calibration support for signal integrity in high-density mobile memory subsystems.
Technical Context
This device implements a double-data-rate interface on both command/address (CA) and data (DQ/DQS) buses, with CA transferred on both CK edges using HSUL_12 signaling. It supports burst lengths of 8 and 16, auto-precharge, and programmable ODT configurations via MR11.
Power management includes deep power-down, self-refresh, and PASR modes enabled through mode registers MR16–MR17. Calibration features include DQ pattern A/B (MR32/MR40), CA training (MR41–MR42/MR48), and WR leveling (MR43–MR47), all coordinated with ZQ calibration (MR13).

Equivalent & Alternatives
The following parts are listed as comparable options for similar LPDDR3 memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MT52L256M32D1PF-107 | Same 4Gb x32 LPDDR3-1066 density and 136FBGA package; differs in VDDQ range (1.14–1.26V vs. 1.14–1.30V) and MR register mapping for PASR | Optimized for Micron's portfolio of automotive-grade LPDDR3; requires validation of MR16–MR17 bit definitions for PASR bank masking | Preferred when sourcing from Micron-authorized channels or when matching existing Micron-based BOMs |
| K4E6E304EC-EGCF | 4Gb x32 LPDDR3-1066 in 136FBGA; uses different ZQ calibration sequence timing and lacks MR48 CA training register | Targeted for Samsung Exynos platforms; CA training must be performed using MR41–MR42 only, limiting skew compensation depth | Recommended for designs already using Samsung memory controllers with proven CA training flow |
Compared with MT52L256M32D1PF-107 and K4E6E304EC-EGCF, the W63CH2MBV provides broader VDDQ tolerance, full MR41–MR48 CA training support, and identical PASR implementation per JEDEC JESD209-3B - making it suitable for flexible controller-agnostic LPDDR3 integration where calibration robustness and voltage margin are critical.

FAQ
What is the maximum data rate supported by the W63CH2MBV?
The W63CH2MBV supports a maximum data rate of 1066 MT/s (megatransfers per second), corresponding to a 533MHz clock frequency. This performance level complies fully with the JEDEC JESD209-3B LPDDR3 standard and is validated across the commercial temperature range (–25°C to +85°C). The W63CH2MBV achieves this rate using HSUL_12 I/O signaling and precise timing control via its mode register configuration.
Does the W63CH2MBV support on-die termination (ODT)?
Yes, the W63CH2MBV supports programmable on-die termination through MR11 (MA[7:0] = 0BH), allowing dynamic configuration of RTT_NOM, RTT_WR, and RTT_PARK values. ODT is active during read, write, power-down, self-refresh, deep power-down, and CA training operations. The W63CH2MBV's ODT levels are calibrated using the external ZQ resistor and can be adjusted in real time to match system impedance requirements.
How does the W63CH2MBV implement partial array self-refresh (PASR)?
The W63CH2MBV implements PASR via two dedicated mode registers: MR16 (MA[7:0] = 10H) for bank-level masking and MR17 (MA[7:0] = 11H) for segment-level masking. This allows selective refresh of only active memory regions, reducing IDD6 current by up to 40% compared to full-array self-refresh. The W63CH2MBV's PASR functionality is fully JEDEC-compliant and requires no external controller modification beyond MR write sequences.
What package type and dimensions does the W63CH2MBV use?
The W63CH2MBV uses a 136-ball fine-pitch ball grid array (FBGA) package conforming to JEDEC MO-229WAA, measuring 10mm × 12mm × 0.8mm with 0.5mm ball pitch. This package supports high-density mobile PCB layouts and is compatible with standard LPDDR3 layout guidelines for signal integrity and thermal management. The W63CH2MBV's ball assignment matches JEDEC LPDDR3 specification for CA, DQ, and power/ground pin placement.
Can the W63CH2MBV operate with a 1.25V VDDQ supply?
Yes, the W63CH2MBV supports VDDQ operation within 1.14V to 1.30V, making 1.25V a fully valid and commonly used supply voltage. This range ensures compatibility with typical PMIC outputs for LPDDR3 interfaces and accommodates voltage droop under transient load. All AC timing specifications, including tDS/tDH and tDQSS, are guaranteed across this entire VDDQ window, and the W63CH2MBV's ZQ calibration adapts automatically to maintain impedance accuracy at 1.25V.
