72132L35P

Overview

The Renesas 72132L35P is an asynchronous FIFO memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 4096 words by 9 bits, providing a total depth of 4096x9. The device supports a maximum data rate of 35 MHz with a typical access time of 35 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 60 mA. The component is housed in a 28-pin PDIP package with a width of 0.600 inches (15.24 mm). It is designed for through-hole mounting and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface integration.
• Standard TTL-compatible logic levels ensure compatibility with common digital systems.
• Dedicated status flags indicate full, empty, and half-full conditions for flow control.

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between different clock domains
• Temporary storage in high-speed data acquisition systems

Procurement Notes

Verify the specific suffix 'L' confirms the leaded PDIP package variant. Confirm RoHS compliance status as older batches may not meet current environmental directives. Check for obsolescence notices from Renesas, as this part number may be discontinued or subject to last-time buy restrictions. Ensure the supplier provides valid traceability documentation for critical applications.

Selection Notes

Select this component when a 4096x9 asynchronous FIFO is required with 35 ns access speed. Compare against wider or deeper alternatives if system bandwidth demands exceed 9-bit width. Consider pinout compatibility with existing PCB layouts designed for 28-pin DIP packages. Evaluate power consumption requirements against the 60 mA maximum specification.

Part Context

This part belongs to the Renesas 7200 series of asynchronous FIFO memories. The series offers various configurations differing in word depth, bit width, and access speeds. The 72132 variant specifically targets applications requiring moderate depth with standard 9-bit data paths, distinguishing it from 8-bit or 16-bit variants in the same family.

Replacement Considerations

Direct substitutes include IDT72132L35P and other manufacturers' equivalent 4096x9 asynchronous FIFOs with identical pinouts and electrical characteristics. Verify functional equivalence regarding flag outputs and reset behavior before substitution.
