Product details
Overview
W632GU6NB12I TR from Winbond is a 2Gb (16M × 8 banks × 16-bit) DDR3L SDRAM operating at 1.35V nominal supply, compliant with DDR3L-1600 (11-11-11) timing, rated for industrial temperature range (−40°C to +95°C), and packaged in a 96-ball VFBGA (7.5 × 13 mm). It serves as main system memory in embedded controllers, network processors, and industrial SoC platforms requiring low-voltage, high-density, JEDEC-compliant DRAM.
For engineers reviewing the W632GU6NB12I TR datasheet, W632GU6NB12I TR pinout, W632GU6NB12I TR application, or W632GU6NB12I TR equivalent, this page delivers verified DDR3L-1600 timing parameters, industrial-grade thermal validation, VFBGA ball mapping, on-die termination (ODT) configuration options, and direct alternatives supporting same-speed binning and JEDEC DDR3L command protocol compatibility.
Technical Context
This device implements an 8-bank, 8-bit prefetch architecture synchronized to differential CK/CK# clocks, with DLL-aligned DQS/DQS# strobes for source-synchronous read/write operation. It supports programmable CAS Latency (CL = 5–11), CAS Write Latency (CWL = 5–8), additive latency (AL = 0, CL−1, CL−2), and dynamic ODT (Rtt_WR) for signal integrity optimization during burst writes.
Key operational modes include auto-precharge, ZQ calibration for output driver and ODT impedance tuning, multi-purpose register (MPR) for system-level timing calibration, and write leveling for per-lane DQ-to-DQS skew compensation. The asynchronous RESET# pin enables deterministic power-up initialization and runtime reset independent of clock state.

Equivalent & Alternatives
The following parts are listed as comparable options for similar DDR3L SDRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS43TR16256B-125KBL | Same 2Gb x16 DDR3L-1600 density and VFBGA-96 package; CL=11, tRCD/tRP = 13.75 ns; supports −40°C to +95°C | Requires identical board layout; differs in ZQ calibration sequence and MPR pattern definition | Drop-in replacement if host controller firmware supports ISSI's MRS encoding and ZQ timing requirements |
| MT41K128M16JT-125:K | 2Gb x16 DDR3L-1600 in 96-ball VFBGA; CL=11, tRCD/tRP = 13.75 ns; industrial temp rated; includes enhanced self-refresh exit timing | Uses Micron-specific ASR entry/exit handshake; slightly tighter tRFC spec (260 ns vs. 240 ns) | Valid alternative where JEDEC-standard ASR behavior is not required; verify tRFC裕度 in high-temperature refresh scenarios |
Compared with W632GU6NB12I TR, IS43TR16256B-125KBL offers identical timing and thermal specs but diverges in MPR implementation, while MT41K128M16JT-125:K provides broader ASR robustness at the cost of stricter tRFC margin-both require validation of host controller's mode register programming and refresh scheduler logic.

FAQ
What is the guaranteed operating temperature range for W632GU6NB12I TR?
W632GU6NB12I TR is specified for industrial operation from −40°C to +95°C case temperature (TCASE), validated per JEDEC JESD22-A104 and JESD22-A106 standards. This includes full AC/DC parameter compliance across the range, with mandatory Auto Self-Refresh (ASR) activation above 85°C to maintain tREFI = 3.9 µs.
Does W632GU6NB12I TR support backward compatibility with standard 1.5 V DDR3 systems?
Yes, W632GU6NB12I TR supports 1.5 V ± 0.075 V operation on both VDD and VDDQ, enabling drop-in replacement in legacy DDR3 designs. However, DDR3L-specific features like lower IDD currents and optimized tREFI scaling are only active at 1.35 V; 1.5 V operation retains full DDR3 command set and timing compatibility.
How is on-die termination configured on W632GU6NB12I TR?
W632GU6NB12I TR supports both static and dynamic ODT. Static Rtt_Nom values (60 Ω, 120 Ω, 40 Ω) are set via MR1 bits A9–A7. Dynamic Rtt_WR (60 Ω or 120 Ω) is enabled via MR2 bit A2 and activated automatically during WRITE bursts. ODT is disabled during reads unless explicitly enabled via MR1.
What is the purpose of the Multi-Purpose Register (MPR) in W632GU6NB12I TR?
The MPR in W632GU6NB12I TR outputs a fixed 128-bit pattern (0x0000_0000_0000_0000) upon READ command when MPR mode is enabled (MR3 A0 = 1). It is used for system-level timing margin analysis, DQ/DQS eye diagram measurement, and write leveling calibration-providing a known, noise-immune reference sequence.
Can W632GU6NB12I TR operate at DDR3L-1866 or DDR3L-2133 speeds?
No. W632GU6NB12I TR is speed-binned exclusively for DDR3L-1600 (11-11-11) operation at 800 MHz clock frequency. While the underlying die may share architecture with faster variants (e.g., W632GU6NB09I), the -12I suffix denotes factory characterization and guarantee only for 1600 MT/s timing; overclocking is not supported or validated.
