Description and Introduction

CMOS Static RAM 1 Meg (128K x 8-Bit) Revolutionary Pinout The **IDT71124S12YI** is a high-speed 16K x 8 dual-port static RAM (SRAM) manufactured by **Integrated Device Technology (IDT)**.  

### **Key Specifications:**  
- **Memory Size:** 16K x 8 (131,072 bits)  
- **Organization:** Dual-port, 8-bit word width  
- **Speed:** 12 ns access time  
- **Voltage Supply:** 5V ±10%  
- **Operating Temperature Range:** Industrial (-40°C to +85°C)  
- **Package:** 48-pin Ceramic DIP (Dual In-line Package)  

### **Features:**  
- **True Dual-Port Operation:** Allows simultaneous access from both ports.  
- **Semaphores:** Built-in hardware semaphore for inter-processor communication.  
- **Bus Arbitration:** On-chip arbitration logic prevents contention.  
- **High-Speed Performance:** 12 ns access time for fast data transfer.  
- **Low Power Consumption:** Standby mode reduces power usage.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Industrial-Grade:** Suitable for harsh environments.  

This device is commonly used in applications requiring high-speed data sharing between processors, such as communication systems, networking, and embedded systems.

Application Scenarios & Design Considerations

CMOS Static RAM 1 Meg (128K x 8-Bit) Revolutionary Pinout

Alternative Part Number

  • CY7C1021CV33-12ZXI --: Pin-compatible 64Kx16 asynchronous SRAM with 12 ns access time in the same 44-pin TSOP II package, widely available and functionally equivalent to the IDT71124.
  • IS61WV102416BLL-10TLI --: 64Kx16 high-speed asynchronous SRAM with 10 ns access time, same 44-pin TSOP II footprint, and a good drop-in replacement with equal or better speed grade.
  • AS7C31026B-12TCN --: 64Kx16 asynchronous SRAM in 44-pin TSOP II with 12 ns access time, offered as a direct second-source alternative for legacy IDT SRAM parts.
