Product details

Overview

W631GG6MB-15 from Winbond Electronics is a 1 Gbit DDR3 SDRAM organized as 8M × 8 banks × 16 bits, compliant with DDR3-1333 (9-9-9) timing, operating at 667 MHz with VDD/VDDQ = 1.5 V ± 0.075 V, and packaged in a RoHS-compliant 96-ball VFBGA (7.5 × 13 mm, 1.0 mm height). It serves as main memory in embedded computing, industrial controllers, and network edge devices requiring JEDEC-standard synchronous DRAM with programmable CAS latency and on-die termination.

For engineers reviewing the W631GG6MB-15 datasheet, W631GG6MB-15 pinout, W631GG6MB-15 application, or W631GG6MB-15 equivalent, key selection considerations include its DDR3-1333 speed grade, -40°C to +95°C commercial temperature range, 96-ball VFBGA package compatibility, and support for ZQ calibration, dynamic ODT, write leveling, and multi-purpose register (MPR)-based system timing calibration.

Technical Context

This DDR3 SDRAM implements an 8-bit prefetch architecture with eight internal banks enabling concurrent access, differential CK/CK# clocking synchronized at the crosspoint, and bi-directional DQS/DQS# strobes edge-aligned on reads and center-aligned on writes. It supports posted CAS with programmable additive latency (AL = 0, CL−1, CL−2), auto-precharge, and burst lengths of 8 (BL8) or 4 (BC4) selectable on-the-fly via mode registers.

The device integrates asynchronous RESET#, programmable CAS Write Latency (CWL), partial array self-refresh (PASR), auto self-refresh (ASR), and dual-mode on-die termination (ODT) - including synchronous and dynamic ODT configurations with RTT_NOM and RTT_WR impedance settings. ZQ calibration uses an external 240 Ω reference resistor to calibrate output drivers and ODT impedances across voltage and temperature.

Equivalent & Alternatives

The following parts are listed as comparable options for similar DDR3 SDRAM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MT41K128M16HA-125:E	1 Gbit DDR3L (1.35 V), 96-ball FBGA, DDR3-1600 (11-11-11), supports 0–95°C but requires lower VDDQ.	Designed for ultra-low-power systems; incompatible with 1.5 V-only controllers; no native DDR3-1333 bin.	Select only if migrating to DDR3L infrastructure and redesigning power delivery; not drop-in compatible with W631GG6MB-15.
IS43TR16128B-15HBL	1 Gbit DDR3, 96-ball FBGA, DDR3-1333 (9-9-9), 0–95°C, but uses 1.5 V ± 0.075 V and supports identical CAS latency range.	Pinout differs in address/command ball mapping (e.g., A10 at B2 vs. A2 in W631GG6MB-15); requires PCB layout change.	Valid functional alternative with matching speed grade and voltage; verify ball map against schematic before substitution.

Compared with MT41K128M16HA-125:E and IS43TR16128B-15HBL, W631GG6MB-15 offers native 1.5 V operation without voltage translation, identical DDR3-1333 timing, and full pin compatibility within Winbond's W631GG6MB family-making it optimal for cost-sensitive industrial designs retaining legacy 1.5 V DDR3 infrastructure.

FAQ

What is the maximum clock frequency supported by the W631GG6MB-15?

The W631GG6MB-15 supports a maximum clock frequency of 667 MHz, corresponding to DDR3-1333 data rates (1333 MT/s). This is defined by its -15 speed grade and validated under JEDEC conditions with CL=9, tRCD=9 ns, and tRP=9 ns. The device does not support higher bins such as DDR3-1600 or DDR3-1866, and attempting to operate beyond 667 MHz violates AC timing specifications and may cause data corruption.

Does the W631GG6MB-15 support write leveling, and how is it implemented?

Yes, the W631GG6MB-15 supports write leveling per JEDEC DDR3 specification. It uses the DQS strobe and internal DLL to adjust DQS-DQ timing skew per byte lane. The memory controller issues a special WRITE command while monitoring DQ feedback to determine optimal DQS delay; the W631GG6MB-15 responds with a known pattern via MPR read mode to confirm calibration success. This feature is essential for reliable operation on long or mismatched PCB traces.

What package type and dimensions does the W631GG6MB-15 use?

The W631GG6MB-15 uses a 96-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA) package measuring 7.5 mm × 13 mm with a 1.0 mm maximum height and 0.8 mm ball pitch. It complies with JEDEC MO-273B mechanical standards and is constructed with lead-free, RoHS-compliant materials. The ball map is fixed and documented in Section 5 of the datasheet; no alternate packages are offered for this speed grade.

Can the W631GG6MB-15 operate at temperatures below 0°C?

No, the W631GG6MB-15 is rated for 0°C ≤ TCASE ≤ 95°C only. For sub-zero operation, Winbond offers the W631GG6MB15I variant (-40°C to +95°C), which shares identical electrical specifications and pinout but undergoes extended temperature screening and qualification. Using W631GG6MB-15 below 0°C risks parametric failure, especially in tREFI refresh timing and ODT impedance accuracy.

How does the ZQ calibration function work on the W631GG6MB-15?

ZQ calibration on the W631GG6MB-15 uses an external 240 Ω ±1% resistor connected between ZQ pin and VSS to calibrate both output driver strength (34 Ω nominal) and on-die termination (ODT) impedances. The internal ZQ engine performs calibration at power-up, after exit from self-refresh, and optionally via ZQINIT/ZQCL commands. Calibration compensates for process, voltage, and temperature variations, ensuring stable SSTL_15 signaling across the full operating range of the W631GG6MB-15.
