W9812G6JB-6I TR

The W9812G6JB-6I TR from Winbond Electronics is a 128 Mbit synchronous DRAM (SDRAM) device organized as 2M words × 4 banks × 16 bits (8M × 16). It supports parallel SDRAM interface operation with a clock frequency up to 166 MHz and is offered in a 54-TFBGA (8×8) package.

Designed for applications that require deterministic parallel memory access and extended temperature operation, this device provides timing detail and operating modes (burst read/write, auto-precharge, self-refresh and power-down) documented in the manufacturer datasheet.

Key Features

• Memory Architecture  Organized as 2M × 4 banks × 16 bits (8M × 16), providing a total density of 128 Mbit in a parallel SDRAM format.
• Performance  Supports up to 166 MHz clock operation with an access time of 5 ns and CAS latency options documented in the datasheet for timing-sensitive designs.
• Power  Operates from a 3.0 V to 3.6 V supply range, supporting common 3 V system rails.
• Package  Available in a 54-TFBGA (8×8) package (supplier device package: 54-TFBGA), suitable for compact board-level integration.
• Temperature Range  Industrial-grade device supported at an ambient operating temperature range of −40 °C to 85 °C (TA) for use in extended-temperature environments.
• Supported SDRAM Commands and Modes  Documented support for bank activate, burst read/write, auto-precharge, precharge, self-refresh, power-down, and other SDRAM command sequences included in the datasheet.

Typical Applications

• Embedded systems  Parallel SDRAM for microcontroller or FPGA-based systems requiring 128 Mbit memory with detailed timing control.
• Industrial control  Memory for control and instrumentation equipment operating across −40 °C to 85 °C.
