Description and Introduction

CMOS PARALLEL-TO-SERIAL FIFO 256 x 16, 512 x 16, 1024 x 16 The IDT72125L50TP is a high-speed, low-power 16K x 8 dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT).  

### **Key Specifications:**  
- **Memory Organization:** 16K x 8 (131,072 bits)  
- **Operating Voltage:** 5V ±10%  
- **Access Time:** 50 ns  
- **Power Consumption:**  
  - Active: 1.5W (max)  
  - Standby: 55mW (max)  
- **Operating Temperature Range:** 0°C to +70°C (commercial)  
- **Package:** 48-pin Thin Plastic Quad Flat Pack (TQFP)  

### **Descriptions and Features:**  
- **Dual-Port Architecture:** Allows simultaneous access from both ports for high-speed data transfer.  
- **Fully Asynchronous Operation:** Independent control signals for each port.  
- **Bus Matching:** On-chip arbitration logic prevents contention when both ports access the same address.  
- **Interrupt Flag:** Supports mailbox communication between processors.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Low-Power CMOS Technology:** Optimized for power-sensitive applications.  
- **Industrial-Grade Options Available:** Extended temperature range (-40°C to +85°C) for harsh environments.  

This device is commonly used in multiprocessor systems, communication buffers, and other applications requiring shared memory access.

Application Scenarios & Design Considerations

CMOS PARALLEL-TO-SERIAL FIFO 256 x 16, 512 x 16, 1024 x 16

Alternative Part Number

  • CY7C425-50PC --: Pin-compatible asynchronous FIFO from Cypress with similar 50 ns speed grade and 1K x 9 organization, widely used as a drop-in replacement for IDT72125 series.
  • SN74ACT7803-50P --: TI asynchronous FIFO in the same 1K x 9 density class with 50 ns access time, offering comparable functionality and DIP package compatibility.
  • 7201LA50TP --: IDT 7201 series asynchronous FIFO with matching 50 ns speed and similar architecture, usable as a functional substitute when the 72125 is unavailable.
  • IDT7202LA50P --: Same vendor FIFO family with similar 50 ns timing and pinout, offering a low-risk replacement from the original manufacturer.
