Features & Applications

The CY7C1471V33-133AXC is a part of CY7C1471 series 3.3 V Pb-free 2 Mb × 36 (72 Mb) memory Thin Quad Flat Pack (14 × 20 × 1.4 mm) Flow-through SRAM with NoBL™ Architecture available in a 100-pin TQFP package. It has an Operating Temperature ranging between 0 °C to 70 °C.

They are synchronous flow through burst SRAMs designed specifically to support unlimited true back-to-back read or write operations without the insertion of wait states .

Product Features:

  • No Bus Latency™ (NoBL™) architecture eliminates dead cycles between write and read cycles
  • Supports up to 133 MHz bus operations with zero wait states
  • Data is transferred on every clock
  • Pin compatible and functionally equivalent to ZBT™ devices
  • Internally self timed output buffer control to eliminate the need to use OE
  • Registered inputs for flow through operation
  • Byte Write capability
  • 3.3 V/2.5 V I/O supply (VDDQ)
  • Fast clock-to-output times
  • 6.5 ns (for 133-MHz device)
  • Clock enable (CEN) pin to enable clock and suspend operation
  • Synchronous self timed writes
  • Asynchronous output enable (OE)
  • Three chip enables (CE1, CE2, CE3) for simple depth expansion
  • Automatic power down feature available using ZZ mode or CE deselect
  • IEEE 1149.1 JTAG Boundary Scan compatible
  • Burst capability — linear or interleaved burst order
  • Low standby power
