Rated for a 133 MHz clock and a 4.2 ns access time, this part is suited for high-throughput data buffering in networking, telecom, and test equipment where the bus must switch direction every cycle without a wait state. ## 119-PBGA footprint and layout considerations Housed in a 119-ball PBGA (14x22 mm body), the part requires a multi-layer PCB for fan-out of the fine-pitch BGA balls — the 0.80 mm or 1.00 mm ball pitch typical of this package family does not route out on two layers.","metaTitle":"Renesas 71V2556SA133BGI SRAM, 4.5Mbit, 133 MHz, 4.2 ns","metaDescription":"Renesas 71V2556SA133BGI synchronous SRAM, 4.5Mbit, 133 MHz clock, 4.2 ns access time.
