- **Refresh:** No refresh required (static RAM)

### **Descriptions:**
The IDT71V65903S75PFI is a high-performance synchronous SRAM designed for applications requiring fast data access and low power consumption. It supports both burst and non-burst operation modes and is commonly used in networking, telecommunications, and high-speed computing systems.

### **Features:**
- **Synchronous Operation:** Clock-controlled read/write operations.
- **Burst Mode Support:** Linear or interleaved burst sequences.
- **Pipelined and Flow-Through Outputs:** Configurable for performance optimization.
- **Single Clock Cycle Deselect:** Reduces power consumption.
- **Byte Write Control:** Individual byte write enable signals.
- **JTAG Boundary Scan:** Supports IEEE 1149.1-compliant testing.
- **Low Standby Power:** Ideal for power-sensitive applications.
- **3.3V Power Supply:** Compatible with modern low-voltage systems.

This SRAM is RoHS-compliant and designed for reliability in high-performance applications.

Application Scenarios & Design Considerations

256K x 36, 512K x 18 3.3V Synchronous ZBT SRAMs

Alternative Part Number

  • IS61WV102416BLL-10TLI --: Pin-compatible 1M x 16 asynchronous SRAM in a 44-pin TSOP II package with comparable 10 ns speed, suitable as a functional substitute for the 512K x 18 synchronous SRAM in many designs.
  • CY7C1061AV33-10ZXI --: 1M x 16 high-speed SRAM from a different series with similar voltage and timing characteristics, commonly used as a cross-reference for IDT 71V series parts.
  • AS7C31026B-10TCN --: Alliance Memory specializes in legacy SRAM replacements and offers 1M x 16 asynchronous SRAMs in TSOP packages that can replace obsolete IDT 71V65903 devices in many applications.
