The GS84018/32/36AT/B-190/180/166/150/100 is a 4Mb synchronous burst SRAM from GSI Technology. It operates at a frequency of 190 MHz–100 MHz, with a core power supply of 3.3 V VDD and I/O power supplies of 3.3 V and 2.5 V. It is available in TQFP and BGA packages.
The GS84018/32/36AT/IB‑190/180/166/150/100 family is a 4 Mb synchronous burst SRAM originally developed for Level‑2 cache applications and now used in DSP main stores and networking chipsets. It is offered in JEDEC‑standard 100‑lead TQFP or 119‑bump BGA packages.
Key features include configurable flow‑through or pipelined operation, single‑cycle deselect (SCD) reads, byte‑write and global‑write modes, and a low‑power sleep mode controlled by the ZZ pin. The device operates from a 3.3 V core supply with 3.3 V/2.5 V I/O compatibility and supports burst frequencies from 190 MHz to 100 MHz.
