The NoBL feature eliminates the idle cycle on bus turnarounds, so a controller can issue a read immediately after a write without a dead clock.","metaTitle":"Infineon CY7C1357C-133AXI NoBL SRAM, 9Mbit, 133 MHz, 6.5 ns","metaDescription":"CY7C1357C-133AXI synchronous SRAM, 9Mbit (512K x 18), 133 MHz clock, 6.5 ns access, 3.3V, -40°C to 85°C.
