CMOS ASYNCHRONOUS FIFO 256 x 9, 512 x 9, 1,024 x 9 The IDT7202LA65D is a high-speed, low-power 1024 x 9-bit asynchronous FIFO (First-In, First-Out) memory manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:
### **Specifications:**
- **Organization:** 1024 x 9-bit
- **Operating Voltage:** 5V ±10%
- **Access Time:** 65 ns
- **Operating Frequency:** Up to 20 MHz
- **Power Consumption:** Low power CMOS technology
- **Operating Temperature Range:** 0°C to +70°C (Commercial)
- **Package:** 28-pin PLCC (Plastic Leaded Chip Carrier) or SOIC (Small Outline Integrated Circuit)
### **Descriptions:**
- The IDT7202LA65D is designed for high-speed data buffering between asynchronous systems.
- It features independent read and write clocks, allowing for simultaneous read and write operations.
- The FIFO includes flags for Full, Empty, Half-Full, and Programmable Almost-Full/Almost-Empty status.
- It supports retransmit capability, enabling data to be reread from the beginning of the memory.
### **Features:**
- **Asynchronous Operation:** No need for synchronization between read and write clocks.
- **Automatic Flag Control:** Simplifies system design by indicating memory status.
- **Expandable Depth and Width:** Can be cascaded for larger FIFO configurations.
- **Low Standby Power:** Ideal for power-sensitive applications.
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing with standard logic devices.
- **Retransmit Function:** Allows re-reading of stored data without resetting the FIFO.
This device is commonly used in data communication, networking, and digital signal processing applications where buffering is required between different clock domains.
