7203L12JG

Overview

The Renesas Electronics Corporation 7203L12JG is an asynchronous FIFO memory device with a storage capacity of 18K bits, organized as 2K x 9. It features a 12ns access time and operates on a single 5.0V supply voltage within the 4.5V to 5.5V range. The component utilizes a unidirectional bus architecture and supports TTL interface levels. It is housed in a 32-pin PLCC package with dimensions of 13.97mm x 11.43mm x 2.79mm and a 1.27mm pitch. The device functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data flow architecture
• TTL-compatible input/output logic levels

Applications

• Data buffering between microprocessors and peripheral devices
• Clock domain crossing synchronization in digital systems
• Interface bridging between components with different timing requirements

Procurement Notes

Verify RoHS compliance status, as some sources indicate non-compliance while others suggest adherence to specific standards. Confirm lead-free availability and moisture sensitivity level (MSL) ratings prior to ordering. Ensure the supplier provides valid traceability documentation for the 32-PLCC package type. Check for any end-of-life notices or obsolescence warnings associated with this specific part number revision.

Selection Notes

Select this component when a 2K x 9 depth and 12ns speed are required for unidirectional data transfer. Compare against the 7203L12P variant if a DIP package is preferred over PLCC. Consider the 7204L12JG if higher density (4K x 9) is needed. Verify that the 5.0V core voltage aligns with the system power rails. Ensure the bidirectional requirement is not present, as this model is unidirectional only.

Part Context

This part belongs to the Renesas 7203L series of asynchronous FIFO memories. It shares architectural similarities with other members like the 7203L12J8 and 7203L15JI but differs in package type and specific timing characteristics. The series is designed for high-speed data buffering applications requiring reliable asynchronous communication between digital logic components.

Replacement Considerations

The 7203L12JG8 is listed as an upgrade alternative by distributors. Verify pin compatibility and electrical specifications before substitution. No direct cross-manufacturer equivalents are confirmed in the provided data.
