7202LA20JI

Overview

The Renesas 7202LA20JI is an asynchronous FIFO memory device with a capacity of 9K bits, organized as 1K words by 9 bits. It supports unidirectional data transfer at a maximum clock frequency of 33.3 MHz and features a typical access time of 20 ns. The component operates on a single 4.5 V to 5.5 V supply voltage with a maximum current consumption of 80 mA. It is housed in a 32-PLCC surface-mount package and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Provides asynchronous first-in-first-out buffering for high-speed data flow management between different clock domains.
• Supports unidirectional data transfer with a 9-bit word width suitable for parallel data bus interfacing.
• Features relay capability to maintain data integrity during read operations while new data is being written.

Applications

• Data buffering in telecommunications equipment
• Interface bridging between microprocessors and peripheral devices
• High-speed digital signal processing systems

Procurement Notes

Verify the specific suffix 'J' corresponds to the 32-PLCC package and commercial temperature grade when sourcing. Confirm RoHS compliance status as older variants may differ from current production runs. Ensure the supplier provides official datasheets matching the IDT/Renesas 7202L series specifications to validate electrical parameters and pinout compatibility before integration.

Selection Notes

Select this component when a 9-bit wide asynchronous buffer is required for unidirectional data paths. The 20 ns access time suits applications operating up to 33.3 MHz. Consider the 32-PLCC package constraints for PCB layout. Compare against other speed grades like the LA12 or LA15 if higher throughput is needed, or verify if bidirectional functionality is necessary for alternative models.

Part Context

This part belongs to the Renesas (formerly IDT) 7202L series of asynchronous FIFO memories. The series offers various speed grades and packaging options to accommodate different system timing requirements. The 7202LA20 variant specifically targets mid-range performance applications requiring reliable data synchronization without complex control logic.

Replacement Considerations

Direct substitutes include other speed grades within the same family such as the 7202LA12JG or 7202LA15JGI8, provided the faster access times are acceptable. Verify pin-to-pin compatibility and ensure the replacement maintains the 9-bit data width and PLCC package form factor.
