Winbond Electronics Corporation W632GG6MB09I

Overview

W632GG6MB09I from Winbond Electronics is a 2 Gb (16M × 8 banks × 16-bit) DDR3 SDRAM supporting DDR3-2133 (14-14-14) operation at up to 1066 MHz clock frequency, with industrial temperature range (–40°C to +95°C), VDD/VDDQ = 1.5 V ± 0.075 V, and SSTL_15 interface compliance. It delivers high-bandwidth memory for embedded controllers, networking processors, and industrial SoC platforms requiring reliable synchronous DRAM with on-die termination and ZQ calibration.

For engineers reviewing the W632GG6MB09I datasheet, W632GG6MB09I pinout, W632GG6MB09I application, or W632GG6MB09I equivalent, key selection considerations include its DDR3-2133 speed grade, industrial temperature rating, 96-ball VFBGA package, programmable CAS Write Latency (CWL), and support for write leveling and multi-purpose register (MPR)-based timing calibration.

Technical Context

This DDR3 SDRAM implements an 8-bit prefetch architecture with eight internal banks, differential CK/CK# and DQS/DQS# signaling, and DLL-based alignment of data strobes to clock edges. It supports posted CAS with programmable additive latency (AL = 0, CL−1, CL−2), auto-precharge, and both synchronous and dynamic on-die termination (ODT) modes.

Functional operation includes ZQ calibration for output driver and ODT impedance tuning using an external 240 Ω resistor, asynchronous RESET# for power-up initialization, and system-level timing calibration via write leveling and MPR readout of predefined bit patterns. The device supports partial array self-refresh (PASR), auto self-refresh (ASR), and multiple power-down modes including precharged and active variants.

FAQ

What is the maximum clock frequency supported by the W632GG6MB09I?

The W632GG6MB09I supports a maximum clock frequency of 1066 MHz, enabling DDR3-2133 data rates (2133 MT/s). This is validated across the full industrial temperature range (–40°C to +95°C) and requires CL=14, nRCD=14, and nRP=14 timing parameters per JEDEC specification. The device maintains this performance with VDD/VDDQ = 1.5 V ± 0.075 V and proper board-level signal integrity design.

Does the W632GG6MB09I support write leveling, and how is it implemented?

Yes, the W632GG6MB09I supports write leveling as defined in JEDEC DDR3 specification. It uses the DQS strobe to calibrate per-device skew relative to CK during initialization. The W632GG6MB09I enters write leveling mode via MR1 bit A6 = 1, then responds to controller-driven patterns on DQ while adjusting internal delay taps. This feature is essential for reliable timing closure in multi-DRAM systems and is confirmed in Section 8.9 of the W632GG6MB09I datasheet.

What is the purpose of the Multi-Purpose Register (MPR) in the W632GG6MB09I?

The MPR in the W632GG6MB09I provides a fixed 128-bit read-only pattern (0x00000000 repeated) used for system-level timing margin verification. Accessed via MR3, it allows the memory controller to perform eye-diagram testing and timing validation without relying on user data. This capability is critical for production test and field reliability analysis, and is explicitly supported in the W632GG6MB09I's functional description (Section 8.10).

How does the W632GG6MB09I handle refresh at elevated temperatures?

At case temperatures above 85°C, the W632GG6MB09I requires either Auto Self-Refresh (ASR) mode (MR2 A6 = 1b) or Manual Self-Refresh with Extended Temperature Range (MR2 A6 = 0b, A7 = 1b) to maintain tREFI = 3.9 µS. This doubles the refresh rate versus standard 7.8 µS intervals, ensuring data retention integrity up to +95°C. The mechanism is mandatory per JEDEC and documented in Section 4 Key Parameters and Section 8.16 of the W632GG6MB09I datasheet.

What package type and ball count does the W632GG6MB09I use?

The W632GG6MB09I uses a 96-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA) package measuring 7.5 mm × 13 mm with 0.8 mm ball pitch and 1.0 mm maximum height. It complies with JEDEC MO-273B and is lead-free/RoHS-compliant. Ball assignments follow standard DDR3 SDRAM layout, including dedicated VDD, VDDQ, and VSS pins for noise isolation - details are provided in Sections 5 and 6 of the W632GG6MB09I datasheet.
