CMOS ASYNCHRONOUS FIFO 256 x 9, 512 x 9 and 1,024 x 9 The IDT7200L is a high-speed, low-power, 9-bit-wide asynchronous FIFO (First-In, First-Out) memory manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:
### **Specifications:**
- **Organization:** 512 x 9 (512 words, 9 bits per word)
- **Operating Voltage:** 5V ±10%
- **Speed Grades:**
- 15 ns access time (IDT7200L15)
- 20 ns access time (IDT7200L20)
- 25 ns access time (IDT7200L25)
- 35 ns access time (IDT7200L35)
- **Power Consumption:** Low power CMOS technology
- **Operating Temperature Range:**
- Commercial (0°C to +70°C)
- Industrial (-40°C to +85°C)
- **Package Options:** 28-pin DIP, PLCC, or SOIC
### **Descriptions:**
- The IDT7200L is a **bi-directional** FIFO, allowing data to be written and read independently.
- It features **asynchronous** operation, meaning read and write clocks are independent.
- Includes **Full (FF) and Empty (EF) flags** to indicate FIFO status.
- Supports **retransmit (RT)** function to reset the read pointer to the first word.
- Designed for high-speed data buffering in applications such as networking, telecommunications, and data acquisition.
### **Features:**
- **High-Speed Operation:** Fast access times (as low as 15 ns).
- **Low Power Consumption:** CMOS technology ensures efficient power usage.
- **Automatic Flag Control:** Full (FF) and Empty (EF) flags prevent overflow/underflow.
- **Expandable Depth:** Multiple FIFOs can be cascaded for deeper storage.
- **Retransmit Capability:** Allows re-reading data from the beginning.
- **Asynchronous Read/Write:** Independent clocking for input and output operations.
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.
The IDT7200L is widely used in applications requiring temporary data storage, rate matching, and buffering between asynchronous systems.
