This matters when the memory shares the bus with other peripherals — a ZBT pipeline keeps the bus saturated at the clock rate, unlike standard synchronous SRAM that inserts a turnaround cycle. With a 10 ns access time, the part supports bus clocks up to 100 MHz in a single-cycle read/write regime. The 36-bit wide word matches a 32-bit data path plus parity or ECC bits without needing a second device. ## Supply and temperature envelope A standard 3.3 V LDO with 1 % initial accuracy and 50 mV dropout margin covers it. The 100-TQFP (14x14 mm) package has a 0.5 mm pitch — a 4-layer PCB with solid ground and power planes under the body is recommended to keep the thermal gradient across the die below 10°C. It is available through authorized and independent distribution channels; pricing and lead time are confirmed at RFQ against the BOM quantity. Bulk packaging means the parts ship in tubes or trays, not tape-and-reel. This is typical for prototype runs and low-volume production where a reel minimum is uneconomical. The date-code spread on a bulk lot is usually tighter than a reel split across multiple production weeks.","metaTitle":"71V547S100PFGI ZBT SRAM, 4.5 Mbit, 10 ns, 100-TQFP","metaDescription":"71V547S100PFGI synchronous ZBT SRAM, 4.5 Mbit organized 128K x 36, 10 ns access, 3.3 V, industrial temp -40 to +85°C.
