Description

The GS8161Z18BGD-250I is an electronic component model belonging to the IC Chips product category. It is an 18Mbit Synchronous Static SRAM manufactured by GSI. The GS8161Z18BGD-250I, along with its variations GS8161Z32(D) and GS8161Z36(T/D), is designed to maximize bus bandwidth utilization by eliminating deselect cycles when switching from read to write cycles. This model offers user-configurable Pipeline and Flow Through modes, as well as NBT (No Bus Turn Around) functionality for zero wait read-write-read bus utilization. The GS8161Z18BGD-250I is fully pin-compatible with other pipelined and flow through NtRAM™, NoBL™, and ZBT™ SRAMs. It is compatible with both 2.5V and 3.3V +10%/–10% core power supply and supports Linear or Interleave Burst mode through the LBO pin. The component also features byte write operation, 3 chip enable signals for depth expansion, automatic power-down functionality through the ZZ pin, and is available in JEDEC-standard 100-lead TQFP and 165-bump FP-BGA packages.
