If the controller runs at a slower clock, the access time gives even more slack for signal-integrity derating across temperature. ## 128K x 36 organization — why the extra bits matter A 36-bit word width is wider than the common x32 or x18 configurations. The extra four bits can carry byte parity or a nibble of ECC syndrome without stealing data bandwidth. The 100-pin LQFP (also specified as 100-TQFP 14x14 mm) is a common surface-mount footprint that reflows easily with standard lead-free profiles. A local LDO or a well-regulated DC-DC is recommended if the system bus voltage wanders.","metaTitle":"71V3577S80PFGI SRAM 4.5Mbit 8 ns 100 MHz 100-TQFP","metaDescription":"71V3577S80PFGI synchronous SRAM, 4.5 Mbit (128K x 36), 8 ns access, 100 MHz clock, 3.3 V, -40°C to 85°C, 100-TQFP.
