Overview
The Renesas Electronics Corporation 7202LA12JI is an asynchronous FIFO memory device belonging to the 7200 series. It provides a storage capacity of 9K bits, organized as 1K words by 9 bits. The component supports unidirectional data bus direction and operates with a maximum data rate of 50MHz. Access time is specified at 12ns. It functions within a supply voltage range of 4.5V to 5.5V, with a maximum supply current of 80mA. The device is housed in a 32-PLCC package (32-LCC J-leads) measuring 14x11.46mm. It supports surface mount installation and operates within a temperature range of 0°C to 70°C.
Feature Summary
- Asynchronous operation for independent read and write clock domains
- Supports retransmit capability for data integrity
- Unidirectional bus architecture
Applications
- Data buffering between asynchronous systems
- Interface bridging in high-speed digital circuits
- Temporary data storage in communication protocols
Procurement Notes
Verify the specific suffix 'JI' against official Renesas documentation to confirm package type and tape/reel specifications, as distributor listings may vary. Ensure RoHS compliance status matches project requirements. Confirm lead-free status and moisture sensitivity level before procurement.
Selection Notes
Select this component when a 9K depth asynchronous FIFO with 12ns access time is required. The 9-bit width accommodates standard byte-plus-parity configurations. Verify that the 32-PLCC package fits the PCB layout constraints and that the 50MHz speed meets system timing requirements.
Part Context
This part belongs to the Renesas 7200 series of asynchronous FIFOs. It shares functional similarities with other members like the 7202LA12JG and 7202LA12J8, differing primarily in packaging or reel specifications. The series is designed for general-purpose data buffering applications requiring reliable asynchronous transfer capabilities.
Replacement Considerations
Check for direct substitutes such as IDT7202LA12JI if available. Verify pin compatibility and electrical parameters before replacing. Consult Renesas PCN documents for any obsolescence notices regarding the 7202L series.
