Product details
Overview
W9816G6JB-6I from Winbond is a 512K × 2 banks × 16-bit synchronous DRAM (SDRAM) operating at 166 MHz with CAS Latency 3, supporting LVTTL interface and auto-precharge, designed for main memory in industrial embedded systems requiring extended temperature operation.
For engineers reviewing the W9816G6JB-6I datasheet, W9816G6JB-6I pinout, W9816G6JB-6I application, or W9816G6JB-6I equivalent, key selection considerations include industrial-grade temperature support (–40°C to +85°C), VFBGA-60 package compatibility, burst length configurability (1/2/4/8/full page), and self-refresh current ≤2 mA.
Technical Context
This SDRAM implements dual-bank interleaving to hide precharge latency and supports programmable mode register settings for burst type (sequential/interleave), burst length, and CAS latency. It uses multiplexed address pins (A0–A10) with bank address (BA) to select one of two internal banks.
Command decoding is fully synchronous to CLK edge, with control signals CS#, RAS#, CAS#, and WE# defining operations including Bank Activate, Read/Write, Auto-precharge, Self-Refresh, and Power Down. DQ masking via LDQM/UDQM enables byte-level write control with zero-latency blocking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 524,288 words × 2 banks × 16 bits = 16 Mbit total capacity |
| Max Clock Frequency | 166 MHz - determines maximum sustained data throughput of 332 MByte/s (16-bit bus) |
| CAS Latency | CL = 3 - defines fixed 3-clock-cycle delay between column command and first valid read data |
| Burst Length | Programmable 1, 2, 4, 8, or full-page - enables efficient sequential access within open row |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments without derating |
| Supply Voltage | 3.0 V to 3.6 V (VDD/VDDQ) - compatible with standard 3.3 V LVTTL logic domains |
| Self-Refresh Current | ≤2 mA - enables low-power retention during system sleep without external refresh controller |
| Refresh Requirement | 2,048 cycles per 32 ms - mandates minimum refresh rate of 64 µs per row |
Pinout & Package
VFBGA-60 package with 0.65 mm ball pitch, RoHS-compliant lead-free construction; 60-ball layout includes dedicated power/ground separation (VDD/VSS for core, VDDQ/VSSQ for I/O) to minimize switching noise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Multiplexed Address | Row/column address inputs shared across banks; A0–A10 used for row, A0–A7 for column |
| BA | Bank Address | Selects one of two internal banks during ACTIVATE or READ/WRITE command |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus with separate input/output paths controlled by LDQM/UDQM |
| CS#, RAS#, CAS#, WE# | Command Control | Active-low command inputs decoded synchronously on CLK rising edge |
| CLK, CKE | Clock Interface | CLK provides timing reference; CKE enables/disables clock domain (Power Down/Self-Refresh entry) |
| LDQM / UDQM | I/O Mask | Low-active mask signals controlling lower/upper 8-bit byte writes and tri-stating outputs during reads |
| VDD, VSS, VDDQ, VSSQ | Power/Ground | Separated core and I/O supplies reduce noise coupling and improve signal integrity |
Key Features
| Feature | Design Value |
|---|---|
| Industrial Temperature Range | –40°C to +85°C operation guaranteed - eliminates need for thermal margining in harsh environments |
| Programmable Burst Mode | Configurable sequential or interleave addressing - optimizes bandwidth for streaming vs. random-access patterns |
| Auto-Precharge Support | Automatic bank closure triggered by A10 high during READ/WRITE - reduces software overhead and improves efficiency |
| Separate I/O Power Rails | VDDQ/VSSQ isolation - suppresses I/O switching noise from affecting core logic timing stability |
| Low-Power Self-Refresh | ≤2 mA current draw - extends battery life in portable/embedded systems during idle periods |
| LVTTL-Compatible Interface | VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures interoperability with legacy 3.3 V microcontrollers and FPGAs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SDRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS42S16160J-6BLI | Same 16Mbit organization, 166 MHz, –40°C to +85°C, but uses TSOP-54 package and lacks VDDQ/VSSQ separation | Preferred where PCB space permits larger footprint and board-level noise control suffices | Choose IS42S16160J-6BLI only if VFBGA assembly capability is unavailable and thermal profile allows TSOP |
| MT48LC16M16A2P-6A:G | Identical speed grade and temperature range, but requires 3.3 V ± 0.3 V supply (no 2.7 V min) and has different AC timing parameters (e.g., tRCD = 20 ns vs. 18 ns) | Suitable for designs already using Micron's DDR SDRAM ecosystem and toolchain | Select MT48LC16M16A2P-6A:G when migrating from existing Micron-based platforms and tRCD margin is sufficient |
Compared with W9816G6JB-6I, IS42S16160J-6BLI trades VFBGA miniaturization and I/O rail isolation for TSOP manufacturability, while MT48LC16M16A2P-6A:G offers broader vendor support but tighter voltage tolerance and slightly relaxed timing margins.

FAQ
What is the maximum operating frequency of the W9816G6JB-6I?
The W9816G6JB-6I is rated for up to 166 MHz operation with CAS Latency 3. This speed grade is validated across the full industrial temperature range (–40°C to +85°C) and requires compliance with tRCD ≥ 18 ns, tRP ≥ 18 ns, and tRC ≥ 42 ns as specified in the official Winbond datasheet revision A01.
Does the W9816G6JB-6I support both sequential and interleaved burst modes?
Yes, the W9816G6JB-6I supports both sequential and interleaved burst addressing modes, configured via the Mode Register Set command. The burst type selection directly affects column address sequencing during burst transfers and is essential for optimizing bandwidth in applications with predictable vs. scattered access patterns.
How does the W9816G6JB-6I handle power-down and self-refresh states?
The W9816G6JB-6I enters Power Down mode when CKE is driven low while all banks are idle, reducing dynamic power consumption. Self-Refresh mode is entered via a dedicated command (CS#, RAS#, CAS# low, WE# high) and maintains data integrity with ≤2 mA current draw, enabling long-duration retention without external refresh control.
What is the purpose of the LDQM and UDQM pins on the W9816G6JB-6I?
LDQM (Lower Data Queue Mask) and UDQM (Upper Data Queue Mask) provide byte-level write masking for the 16-bit DQ bus. When asserted high during a write cycle, each masks its respective 8-bit lane with zero latency; during reads, they place the corresponding output drivers in high-impedance state after CAS latency delay.
Can the W9816G6JB-6I be used as a direct replacement for the W9816G6JB-6?
No - while both share identical speed grade (166 MHz/CL3), the W9816G6JB-6I is qualified for –40°C to +85°C operation, whereas the W9816G6JB-6 is commercial-grade (0°C to +70°C). Substituting W9816G6JB-6I into a design originally specifying W9816G6JB-6 is safe; reverse substitution violates temperature specifications and may cause functional failure under cold conditions.
