7205L12J8

Overview

The Renesas Electronics Corporation 7205L12J8 is an asynchronous FIFO memory device belonging to the 7200 series. It features a storage organization of 4K x 9 bits, providing a total capacity of 36 kilobits. The component operates with a maximum access time of 12 nanoseconds and supports data rates up to 50 MHz. It functions as a unidirectional bus interface designed for 5.0 V TTL logic levels. The device is housed in a 32-pin Plastic Leadless Chip Carrier (PLCC) package with J-leads. Operating conditions are specified within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation utilizing independent read and write clock domains for flexible data buffering between different speed subsystems.
• Unidirectional data flow architecture supporting single-direction transfer from input port to output port.
• CMOS technology implementation ensuring compatibility with standard 5V logic families while maintaining low power consumption profiles.

Applications

• Data buffering in high-speed serial-to-parallel conversion circuits
• Interface bridging between microprocessors and peripheral devices operating at different clock speeds
• Temporary data storage in digital signal processing pipelines

Procurement Notes

Verify current availability status as this component may be discontinued or subject to limited supply constraints. Confirm package authenticity and check for moisture sensitivity level requirements during handling. Ensure compliance with RoHS directives if applicable to your specific manufacturing region. Review official datasheets for updated electrical characteristics before final integration into design specifications.

Selection Notes

Select this component when designing systems requiring moderate depth FIFO buffers with 9-bit word widths. The 12ns access time suits applications needing fast data throughput without complex synchronization logic. Consider the PLCC-32 package for through-hole mounting requirements. Evaluate power dissipation limits against system thermal constraints given the 5V operating voltage specification.

Part Context

This part belongs to the Renesas 7200 series of asynchronous FIFO memories, originally developed by Integrated Device Technology (IDT) before acquisition. The series offers various density and speed combinations. The 7205 variant specifically targets mid-range performance needs. Related parts include the 7202 and 7203 series with differing depths and access times.

Replacement Considerations

Cross-reference with IDT7205L12J8 for identical functional specifications. Verify pinout compatibility with existing PCB layouts. Check for equivalent timing parameters in alternative CMOS FIFO offerings from other manufacturers if direct substitutes are unavailable.
