QS7203-35V

FIFOs Memory Overview

The QS7203-35V is an asynchronous FIFO memory device manufactured by Quality Semiconductor. It features a memory organization of 2K x 9 bits, providing a total density of 18 kilobits. The component supports a maximum access time of 35 nanoseconds and operates with a cycle time of 25 nanoseconds. It utilizes CMOS technology and includes three-state outputs for bus interfacing. The device functions within a supply voltage range of 4.5 V to 5.5 V and is designed for parallel data transfer in asynchronous modes.

FIFOs Memory Feature Summary

• Asynchronous operation mode for flexible clock domain crossing
• CMOS technology ensuring low power consumption
• Three-state outputs for efficient bus sharing
• Retransmit capability for data integrity

FIFOs Memory Applications

• Buffering data between microprocessors and peripherals
• Interface bridging between different clock domains
• Data acquisition systems requiring temporary storage
• Communication interface buffering in industrial control

FIFOs Memory Procurement Notes

Verify the specific suffix 'V' indicates the correct package variant and temperature rating during sourcing. Confirm that the component meets RoHS compliance requirements if applicable to your assembly process. Ensure compatibility with existing PCB footprints, as package dimensions may vary across the QS7203 family. Check for obsolescence status or lifecycle notices from the manufacturer before finalizing procurement plans.

FIFOs Memory Selection Notes

Select this part when a 2K x 9 asynchronous FIFO with 35 ns access speed is required. Compare against other QS7203 variants based on access time (e.g., -15J, -25V) and package type (PQCC32 vs. PDIP). Ensure the 5.0 V core voltage aligns with system logic levels. Verify that the asynchronous interface matches the controller's timing requirements rather than synchronous alternatives.

FIFOs Memory Part Context

The QS7203 series comprises various asynchronous FIFO devices from Quality Semiconductor. Variants differ primarily in access speed and physical packaging. The QS7203-35V specifically denotes the 35 nanosecond access time version. This family is designed for general-purpose buffering applications where simple asynchronous handshaking is preferred over complex synchronous protocols.

FIFOs Memory Replacement Considerations

Direct substitutes include other QS7203 variants such as QS7203-35P or QS7203-25V, provided pinout and electrical characteristics match. Cross-reference with generic 2Kx9 asynchronous FIFOs only if pin compatibility and voltage levels are verified. Ensure any replacement maintains the same asynchronous control signal definitions.
