7202LA12TP

Overview

The Renesas Electronics Corporation 7202LA12TP is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It supports unidirectional data transfer at a maximum data rate of 50MHz and features a typical access time of 12ns. The component operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 80mA. Designed for through-hole installation, it is housed in a 28-PDIP package (0.300 inch width). The device functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation enables independent read and write clock domains for flexible interface integration.
• Retransmit capability allows repeated reading of the same data word without advancing the read pointer.
• CMOS parallel architecture provides high-speed data handling with low power consumption.

Applications

• Buffering data streams between components operating at different clock speeds
• Data acquisition systems requiring temporary storage before processing
• Communication interfaces managing variable throughput rates

Procurement Notes

Verify the specific package type and pinout configuration against the official datasheet to ensure compatibility with the target PCB footprint. Confirm that the supply voltage requirements align with the system design constraints. Check for any recent product change notifications regarding manufacturing location or material composition updates from Renesas Electronics Corporation prior to finalizing procurement orders.

Selection Notes

Select this component when a 9K bit asynchronous FIFO with 9-bit word width is required. Ensure the design accommodates the 28-pin through-hole package dimensions. Verify that the 50MHz maximum frequency meets the system timing requirements. Consider the 0°C to 70°C operating temperature range suitability for the intended environment.

Part Context

The 7202LA12TP belongs to the Renesas 7202L series of CMOS parallel FIFOs. This series offers various capacities and speed grades, providing flexibility for different buffering needs. The 7202 variant specifically provides 1K x 9 depth, balancing memory size and performance for moderate data throughput applications.

Replacement Considerations

Cross-reference with other 7202L series parts such as 7202LA12JG or 7202LA12SOG8 if package differences are acceptable. Verify electrical specifications and pinouts match exactly before substitution.
