7201LA20TP

Overview

The IDT7201LA20TP is a CMOS asynchronous dual-port FIFO with a 512 x 9 organization. It features a 20ns access time and operates on a single 5V supply within the 4.5V to 5.5V range. The device utilizes CEMOS technology for low power consumption, offering 440mW active and 28mW power-down modes. It includes status flags for Empty, Half-Full, and Full conditions, along with auto-retransmit capability. The component is housed in a 28-pin PLCC package.

Feature Summary

• Asynchronous read and write operations allow independent clock domains for input and output ports.
• Auto-retransmit capability ensures data integrity during bus contention or error conditions.
• Expandable architecture supports unlimited depth and width expansion using standard logic gates.

Applications

• Data buffering between high-speed processors and slower peripheral interfaces
• Protocol conversion bridges requiring temporary storage for packet alignment
• Digital signal processing systems needing decoupling of parallel data streams

Procurement Notes

Verify the specific suffix 'TP' against official Renesas/IDT documentation to confirm package type and temperature grade. Confirm RoHS compliance status as older IDT parts may vary. Check for obsolescence notices from Renesas Electronics, as this component belongs to an older generation that may have limited availability or require lifecycle management planning.

Selection Notes

Select this component when a 512-word by 9-bit depth is required with asynchronous interface timing. Ensure the system design accommodates the 20ns access speed and 32-pin PLCC footprint if applicable. Consider the 5V logic level compatibility with existing board components. Evaluate power constraints against the specified 440mW active current draw.

Part Context

This part belongs to the IDT 7201L family of CMOS asynchronous FIFOs. It shares functional compatibility with the broader 720X series, including the 7200 and 7202 variants which offer different memory depths. The family is characterized by high-speed operation and low power consumption using CEMOS technology, widely used in telecommunications and industrial control applications prior to newer synchronous alternatives.

Replacement Considerations

Public confirmed substitute: 7201LA12JG (Renesas). Verify pinout and electrical specifications match before substitution.
