The 36-bit word width suits DSP datapaths, network packet buffers, and wide cache-tag arrays where a single chip replaces multiple narrower memories. Operating from a 3.135 V to 3.6 V supply and rated over -40 to 85 °C, it fits industrial telecom and factory-automation backplanes. ## 100 MHz clock and 8.5 ns access — bus margin for pipelined designs The 100 MHz clock rate sets the synchronous pipeline cadence; the 8.5 ns access time is the window from clock edge to valid data out. In a back-to-back read sequence, the pipeline delivers one word per clock cycle once the initial latency is absorbed. ## Package and mounting — 165-FBGA (13x15) Housed in a 165-ball FBGA measuring 13 mm by 15 mm, the CY7C1381D-100BZXI is surface-mount only. The fine-pitch BGA requires controlled solder-paste deposition and X-ray inspection for void detection. No socket option exists for this footprint; the part is soldered directly to the PCB, so a board respin is needed if a pin-compatible substitute is later adopted.","metaTitle":"Infineon CY7C1381D-100BZXI 18Mbit Synchronous SRAM, 100 MHz","metaDescription":"CY7C1381D-100BZXI 18Mbit synchronous SRAM, 100 MHz clock, 8.5 ns access, 512K x 36, industrial temp, 165-FBGA.
