7201LA12PDG

Overview

The Renesas 7201LA12PDG is an asynchronous FIFO memory device with a storage capacity of 4.5K bits, organized as 512 words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 50 MHz with an access time of 12 ns. The component features unidirectional bus architecture and is housed in a 28-PDIP package. Maximum supply current is 80 mA, and it functions within a temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous dual-port FIFO memory architecture for independent read/write clock domains
• Utilizes Full and Empty flags to manage data flow and prevent overflow or underflow conditions
• Supports standard CMOS parallel interface with 9-bit data width

Applications

• Data buffering between components operating at different clock speeds
• Interface bridging in high-speed digital systems requiring temporary data storage
• Parallel data transfer applications in industrial control environments

Procurement Notes

Verify the specific suffix 'PDG' confirms the 28-pin PDIP package and leaded construction. Confirm RoHS compliance status as legacy parts may vary. Ensure the supplier provides valid traceability documentation for this discontinued or end-of-life series component before finalizing procurement orders.

Selection Notes

Select this part when a 512x9 asynchronous FIFO is required in a through-hole DIP package. Compare against the SOIC variant (7201LA12SOG8) if surface mount space is limited. Verify that the 12 ns access time meets system timing requirements and that the 5V logic levels are compatible with the target application circuitry.

Part Context

This component belongs to the Renesas 7201L series of asynchronous FIFO memories. It is functionally similar to other variants like the 7201LA12SOG8 but differs in packaging technology. The PDG suffix specifically denotes the plastic dual in-line package format suitable for prototyping or legacy board designs.

Replacement Considerations

Public confirmed substitute: 7201LA12SOG8.
