Description and Introduction

128K x 36, 256K x 18, 3.3V Synchronous ZBT SRAMs 3.3V I/O, Burst Counter, Flow-Through Outputs The IDT71V3557-S75PF 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:** 524,288 words × 36 bits  
- **Supply Voltage:** 3.3V ± 0.3V  
- **Speed:** 7.5 ns (133 MHz)  
- **Access Time:** 7.5 ns  
- **Cycle Time:** 7.5 ns  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 100-pin TQFP (14mm × 20mm)  
- **I/O Type:** Common I/O (3.3V LVTTL-compatible)  
- **Refresh:** Not required (Static RAM)  

### **Descriptions:**  
- The IDT71V3557-S75PF is a synchronous pipelined SRAM designed for high-performance applications.  
- It features a fully synchronous operation with a single clock (CLK) input.  
- Supports burst mode operation for high-speed data transfer.  
- Includes on-chip address registers for pipelined read/write operations.  

### **Features:**  
- **Pipelined Operation:** Enables high-speed data access with registered inputs and outputs.  
- **Burst Mode Support:** Linear or interleaved burst sequences (configurable via MODE input).  
- **Single Clock Synchronization:** All operations synchronized to the rising edge of CLK.  
- **Byte Write Control:** Individual byte write enables (BW1-BW4) for selective writes.  
- **Self-Timed Write Cycle:** Simplifies timing control.  
- **Low Standby Power:** Automatic power-down mode when deselected.  
- **JTAG Boundary Scan:** Supports IEEE 1149.1-compliant boundary scan testing.  
- **3.3V LVTTL-Compatible I/O:** Ensures compatibility with standard logic levels.  

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