Description and Introduction

128K x 36, 256K x 18, 3.3V Synchronous ZBT SRAMs 3.3V I/O, Burst Counter, Flow-Through Outputs The IDT71V3557S75PF is a high-speed 3.3V CMOS synchronous SRAM manufactured by Integrated Device Technology (IDT). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Density:** 512K x 36 (18 Mbit)  
- **Organization:** 512K words × 36 bits  
- **Voltage Supply:** 3.3V ± 0.3V  
- **Speed:** 75 ns access time  
- **Package:** 100-pin TQFP (Thin Quad Flat Pack)  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **I/O Type:** 3.3V LVTTL-compatible  

### **Descriptions:**
- The IDT71V3557S75PF is a synchronous pipelined SRAM designed for high-performance applications requiring fast access times and large memory capacity.  
- It supports burst mode operation for efficient data transfer.  
- Features a common I/O architecture with byte write control.  

### **Features:**
- **Synchronous Operation:** Clock-controlled read/write operations.  
- **Pipelined Output:** Enables high-speed burst access.  
- **Burst Mode Support:** Linear or interleaved burst sequences.  
- **Byte Write Control:** Individual byte write enables (BW1-BW4).  
- **Single Clock Cycle Deselect:** Minimizes power consumption.  
- **Self-Timed Write Cycle:** Simplifies timing control.  
- **JTAG Boundary Scan:** Supports IEEE 1149.1-compliant testing.  
- **Low Standby Power:** Suitable for power-sensitive applications.  

This SRAM is commonly used in networking, telecommunications, and high-performance computing systems.
