7203L20TP

Overview

The Renesas Electronics Corporation 7203L20TP is a unidirectional asynchronous FIFO memory device with an organization of 2K x 9 bits, providing a total storage density of 18 kilobits. It features a maximum access time of 20 nanoseconds and operates at a data rate of 33.3 MHz. The component requires a core voltage supply ranging from 4.5 V to 5.5 V and draws a maximum supply current of 120 mA. It is housed in a 28-pin Plastic Dual In-Line Package (PDIP) with a lead pitch of 2.54 mm. The device supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Unidirectional data transfer architecture for simple interface integration
• Asynchronous operation allowing independent clock domains for read and write ports
• Standard TTL-compatible I/O levels for direct logic interfacing

Applications

• Buffering data streams between microprocessors and peripheral devices
• Synchronizing data transfers across different clock frequencies
• Temporary data storage in high-speed digital signal processing chains

Procurement Notes

Verify the specific suffix 'TP' against official Renesas documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status as legacy components may vary. Check for obsolescence notices or end-of-life declarations before finalizing procurement plans. Ensure the supplier provides valid traceability for vintage semiconductor parts.

Selection Notes

Select this component when a 2K x 9 depth and 20 ns speed are required for unidirectional buffering. Compare against the 7203L12 series for faster access times or the 7203L35 series for slower, potentially lower-cost options. Ensure the 28-pin PDIP footprint matches the target PCB design constraints and thermal requirements.

Part Context

The 7203L20TP belongs to the Renesas 7200 series of asynchronous FIFOs, originally developed by Integrated Device Technology (IDT) before its acquisition by Renesas. This family provides versatile memory solutions for bridging timing mismatches in digital systems. The 7203 variant specifically offers 9-bit word width, suitable for standard byte-oriented applications with parity or extended data handling.

Replacement Considerations

Official substitutes include the 7203L12JG8 for faster performance. Verify pin compatibility and electrical characteristics with any cross-reference part.
