Product details
Overview
W631GG6NB11I TR from Winbond is a 1G-bit DDR3 SDRAM organized as 8M × 8 banks × 16 bits, supporting DDR3-1866 (13-13-13) operation at up to 933 MHz clock frequency with CAS Latency 13, 1.5V VDD/VDDQ supply, and industrial temperature range (–40°C to +95°C). It serves as main system memory in embedded controllers, networking processors, and industrial HMIs requiring high-bandwidth, low-latency synchronous DRAM.
For engineers reviewing the W631GG6NB11I TR datasheet, W631GG6NB11I TR pinout, W631GG6NB11I TR application, or W631GG6NB11I TR equivalent, this page delivers verified DDR3 timing parameters, ball configuration, ODT and ZQ calibration support, and industrial-grade thermal validation - critical for memory subsystem design, signal integrity planning, and JEDEC-compliant layout implementation.
Technical Context
This DDR3 SDRAM implements an 8-bit prefetch architecture with eight internal banks enabling concurrent access, DLL-aligned DQ/DQS timing, and source-synchronous differential strobe (DQS/DQS#) I/O referenced to CK/CK#. It supports programmable CAS Write Latency (CWL = 5–9), additive latency (AL = 0, CL−1, CL−2), and posted CAS for command bus efficiency.
Key operational modes include auto-precharge, burst refresh, self-refresh with ASR/PASR support, and dual power-down states (precharged and active). On-die termination (ODT) is configurable via mode registers MR1 and MR2 for RTT_NOM, RTT_WR, and dynamic ODT, with ZQ calibration using an external 240 Ω resistor for output driver and ODT impedance tuning.

FAQ
What is the maximum clock frequency supported by the W631GG6NB11I TR?
The W631GG6NB11I TR supports a maximum clock frequency of 933 MHz, corresponding to DDR3-1866 operation with CL13/tRCD/tRP = 13-13-13 timing. This is validated across the full industrial temperature range (–40°C to +95°C) and requires tCK(AVG) ≤ 1.07 ns for stable operation under worst-case voltage and process corners.
Does the W631GG6NB11I TR support on-die termination (ODT) and how is it configured?
Yes, the W631GG6NB11I TR supports programmable ODT via MR1 and MR2. RTT_NOM (60 Ω, 120 Ω, 40 Ω) is set in MR1 for read operations, while RTT_WR (60 Ω, 120 Ω, 40 Ω) is enabled dynamically during writes via MR2. Configuration requires mode register writes after power-up initialization and ZQ calibration.
What is the purpose of the ZQ pin on the W631GG6NB11I TR and what external component is required?
The ZQ pin on the W631GG6NB11I TR connects to a 240 Ω ±1% external resistor to ground, enabling factory-trimmed and runtime-calibrated output driver strength and ODT impedance. This ensures signal integrity across voltage and temperature variations and is mandatory before normal operation begins.
How does the W631GG6NB11I TR handle refresh at elevated temperatures above 85°C?
At TCASE > 85°C, the W631GG6NB11I TR requires doubled refresh rate (tREFI = 3.9 µS instead of 7.8 µS). This is achieved either by enabling Auto Self-Refresh (ASR) via MR2 A6=1b or by entering Manual Self-Refresh mode with MR2 A6=0b and A7=1b - both validated for operation up to +95°C.
Can the W631GG6NB11I TR operate with DDR3L voltage levels (1.35 V)?
No, the W631GG6NB11I TR is specified for 1.5 V ± 0.075 V (VDD and VDDQ) only and is not rated for DDR3L operation. Using 1.35 V will result in undefined behavior, failed initialization, or excessive bit errors due to insufficient noise margin and driver strength.
