Description and Introduction

HIGH-SPEED 3.3V 8K x 8 DUAL-PORT STATIC RAM The IDT70V05S55PF is a high-speed, low-power 5V CMOS synchronous FIFO (First-In, First-Out) memory device manufactured by Integrated Device Technology (IDT). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Density:** 512K x 9 bits (4.5 Mbits)  
- **Organization:** 512K × 9  
- **Supply Voltage:** 5V ±10%  
- **Operating Frequency:** Up to 100 MHz  
- **Access Time:** 5.5 ns  
- **Power Consumption:** Low-power CMOS technology  
- **I/O Compatibility:** 5V TTL-compatible inputs and outputs  
- **Package:** 100-pin TQFP (Thin Quad Flat Pack)  

### **Descriptions:**
- The IDT70V05S55PF is a synchronous FIFO designed for high-speed data buffering applications.  
- It supports simultaneous read and write operations with independent clocks.  
- Features programmable flags (Almost Full, Almost Empty) for flow control.  
- Includes retransmit capability for data recovery.  

### **Features:**
- **High-Speed Operation:** 100 MHz clock frequency with 5.5 ns access time.  
- **Low Power:** CMOS technology for reduced power consumption.  
- **Synchronous Operation:** Independent read and write clocks.  
- **Programmable Flags:** Almost Full (AF) and Almost Empty (AE) for efficient data management.  
- **Retransmit Function:** Allows re-reading of data without external address management.  
- **TTL-Compatible I/O:** Ensures easy interfacing with standard logic devices.  
- **Industrial Temperature Range:** Supports operation from -40°C to +85°C.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

HIGH-SPEED 3.3V 8K x 8 DUAL-PORT STATIC RAM

Alternative Part Number

  • CY7C025-55AC --: Dual-port SRAM with comparable 8Kx16 organization and 55 ns access time, pin-compatible footprint in many designs and widely available as a second source.
  • 7130LA55PF --: Same 8Kx16 dual-port SRAM family from the successor vendor with matching 55 ns speed grade and TQFP package, offering a direct functional drop-in.
  • IS61LPS51236A-55TQ --: High-speed SRAM with 55 ns timing and similar package, suitable as a functional substitute when dual-port arbitration is not strictly required.
  • AS7C34096A-55TC --: Alliance Memory SRAM offering comparable density and 55 ns timing, often used as a drop-in replacement for legacy IDT SRAM parts.
