Description and Introduction

128K X 36, 3.3V Synchronous SRAM with ZBT Feature, Burst Counter and Flow-Through Outputs The IDT71V547S-100PF is a high-speed, low-power 3.3V CMOS synchronous dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are the key specifications, descriptions, and features:

### **Specifications:**  
- **Density:** 512K x 18-bit (9,437,184 bits)  
- **Organization:** Dual-port (independent read/write ports)  
- **Supply Voltage:** 3.3V ±10%  
- **Speed Grade:** 100 MHz (10 ns access time)  
- **Operating Current:** 350 mA (typical)  
- **Standby Current:** 5 mA (typical)  
- **I/O Type:** 3.3V CMOS-compatible  
- **Package:** 100-pin TQFP (Thin Quad Flat Pack)  
- **Temperature Range:** Commercial (0°C to +70°C)  

### **Descriptions:**  
- The IDT71V547S-100PF is a synchronous dual-port RAM with independent control, address, and data buses for each port.  
- It supports simultaneous access from both ports, enabling high-speed data transfer between processors or systems.  
- Designed for applications requiring high bandwidth and low latency, such as networking, telecommunications, and data buffering.  

### **Features:**  
- **True Dual-Port Operation:** Allows simultaneous reads and writes on both ports.  
- **Synchronous Interface:** Clock-controlled for high-speed operation.  
- **Byte Write Control:** Individual byte enables for write operations.  
- **Bus Matching:** On-chip arbitration logic prevents contention.  
- **Low Power Consumption:** Features standby and sleep modes for power savings.  
- **JTAG Boundary Scan:** Supports IEEE 1149.1-compliant test access.  
- **Flow-Through or Pipelined Operation:** Configurable for performance optimization.  

This device is ideal for high-performance systems requiring fast, concurrent data access.

Application Scenarios & Design Considerations

128K X 36, 3.3V Synchronous SRAM with ZBT Feature, Burst Counter and Flow-Through Outputs

Alternative Part Number

  • IS61WV51216EDBLL-10TLI --: 512Kx16 asynchronous SRAM with comparable 10ns speed grade and 3.3V operation, pin-compatible 44-pin TSOP package, widely available as a drop-in replacement for the 71V547.
  • CY7C1041G-10ZSXI --: 256Kx16 fast asynchronous SRAM with 10ns access time and 3.3V supply, similar 44-pin TSOP II footprint, suitable functional substitute when density tolerance allows.
  • AS7C34098A-10TCN --: 256Kx16 high-speed CMOS SRAM with 10ns cycle time and 3.3V interface, offered in 44-pin TSOP, commonly used as a second-source alternative for IDT 71V-series SRAMs.
