CY7C1481BV33-133AXI is a 72-Mbit (2M × 36) synchronous flow-through SRAM for secondary cache and high-speed processor interfaces. It supports 133 MHz operation with 6.5 ns clock-to-data access and 2-1-1-1 burst reads using an on-chip 2-bit wraparound counter (linear or interleaved via MODE). Common I/O, byte writes (BWx/BWE) and global write (GW), JTAG, and ZZ sleep mode are included.
