Product Overview
The W989D6DBGX6I is a low-power 512-Mbit Mobile LPSDRAM from Winbond, designed for battery-powered embedded devices. Operating at a 1.8V core & I/O voltage, organized as 32M x 16 (4 internal banks), it supports up to 166MHz data bandwidth. Equipped with PASR, TCSR, DPD and programmable burst lengths, this IC is packaged in compact 54-ball VFBGA, industrial grade (-40℃ to +85℃), balancing low power consumption, stable high-speed performance for handheld equipment, IoT gateways and embedded systems.
Core Advantages
1.8V Low Power Architecture
Works within 1.7V~1.95V voltage range, greatly reducing power consumption compared to traditional 3.3V DRAM solutions.
Multiple Low-Power Modes
Supports PASR, TCSR and DPD functions to lower standby power and extend battery working time for portable products.
Stable High-Speed Bandwidth
Max 166MHz operating frequency with adjustable CAS latency and auto-precharge, ideal for real-time audio, video and data buffering.
Industrial Grade & Compact Package
54-ball VFBGA small form factor, wide -40℃~+85℃ temperature range, reliable operation in compact and harsh embedded hardware.

Frequently Asked Questions
Q1: What does LPSDRAM stand for in W989D6DBGX6I specifications?
A: LPSDRAM stands for Low Power Synchronous DRAM. It is a low-power variant of standard SDRAM, designed for portable hardware with 1.8V supply and self-refresh power-saving features.
Q2: What does the “6I” suffix mean on W989D6DBGX6I?
A: “6I” refers to -6 speed grade (max 166MHz) and industrial temperature range, supporting stable operation from -40℃ to +85℃.
Q3: Can W989D6DBGX6I work directly with a 3.3V power supply?
A: No. This chip requires 1.7V ~ 1.95V (nominal 1.8V). Powering it from a 3.3V rail will exceed electrical ratings and cause permanent damage.
Q4: How do PASR and TCSR functions reduce power consumption?
A: PASR only refreshes memory regions storing valid data; TCSR dynamically adjusts refresh rate based on temperature. Both greatly lower standby current for battery-powered equipment.
Q5: Are there alternative pin-to-pin compatible memory ICs for W989D6DBGX6I?
A: We can offer compatible LPSDRAM alternatives upon request. Alternatives depend on frequency, temperature grade and package requirement. Submit an inquiry with your BOM for cross reference recommendation.
Q6: Is W989D6DBGX6I available in Tape & Reel packaging?
A: Yes, this model is supplied in both Tray and Tape & Reel formats to match SMT mass production demands.
Q7: Does W989D6DBGX6I comply with RoHS and halogen-free standards?
A: Yes, the component is RoHS compliant, lead-free and halogen-free, meeting requirements for industrial and consumer embedded products.
Q8: Can I get free samples of W989D6DBGX6I for hardware testing?
A: Sample support is available. Fill in the inquiry form with your project details, and our sales team will confirm sample quantity and lead time.
