This is a parallel-interface, volatile memory — the 36-bit-wide data bus suits systems that need high-throughput read/write cycles without serialization overhead, such as network buffers, cache tag stores, or FPGA local memory. This part is marked Obsolete by the manufacturer. ## Supply and temperature grade The commercial temperature range of 0°C to 70°C covers indoor equipment, telecom central office, and enterprise storage; it does not extend to industrial or automotive ambient extremes. Housed in a 165-ball FBGA (15x17 mm) package. The 1.0 mm ball pitch demands controlled-impedance PCB routing for the 36-bit data bus at 133 MHz — signal integrity considerations include matched trace lengths and adequate decoupling near the BGA footprint.","metaTitle":"Infineon CY7C1481BV33-133BZXC 72Mbit SRAM, 6.5 ns","metaDescription":"Infineon CY7C1481BV33-133BZXC 72Mbit synchronous SRAM, 133 MHz, 6.5 ns access time.
