7207L20PDG

Overview

The Renesas Electronics Corporation 7207L20PDG is an asynchronous FIFO memory device with a density of 288K bits, organized as 32K words by 9 bits. It features a 20 ns access time and operates within a supply voltage range of 4.5 V to 5.5 V. The component supports a data rate of 33.3 MHz and utilizes a unidirectional architecture. It is housed in a 28-pin PDIP package with a lead pitch of 15.24 mm (0.600 inches). The device is designed for applications requiring simultaneous asynchronous read and write operations.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing environments
• Includes status flags such as Empty, Half-Full, and Full to prevent data overflow and underflow
• Features auto-retransmit capability allowing reset of the read pointer to its initial position

Applications

• Multiprocessing systems requiring high-speed data buffering
• Rate buffer applications between mismatched data speeds
• Asynchronous interface circuits in digital signal processing

Procurement Notes

Verify the specific package variant, as the 7207L20 series includes PLCC and Cerdip options. Confirm RoHS compliance status, as some variants are marked non-compliant. Check current lifecycle status, as certain suffixes indicate end-of-life or limited availability. Ensure the selected part matches the required temperature grade for the intended operating environment.

Selection Notes

Select this component when a 32K x 9 organization is required for unidirectional data flow. Choose based on the necessary access time, with 20 ns being standard for this model. Consider the 28-pin DIP package for through-hole mounting requirements. Verify compatibility with existing system voltage levels, specifically the 5V TTL interface.

Part Context

This part belongs to the 7207L20 series of CMOS parallel FIFOs. It is functionally compatible with the broader 720X family, offering low power consumption and ultra-high speed performance. The series is available in various packages including PLCC, Cerdip, and PDIP, catering to different manufacturing and integration needs.

Replacement Considerations

The IDT7207L20J8 is listed as an alias for this component. Verify pinout and electrical specifications against the original design requirements before substitution. Other members of the 7207 family may offer different access times or packaging options.
