133 MHz synchronous SRAM with 4 ns access time
The Cypress CY7C1347G-133BGXC is a 4.5 Mbit synchronous SRAM organized as 128K words by 36 bits. The 36-bit word width suits applications that need wide data buses — typically packet buffers, FIFO implementations, and cache tag stores in networking and telecom line cards.
This limits the part to indoor, temperature-controlled environments such as server rooms, central offices, and lab equipment.
