7208L20JG8

Overview

The Renesas Electronics Corporation 7208L20JG8 is an asynchronous FIFO memory IC with a storage capacity of 576K bits, organized as 64K words by 9 bits. It features a parallel interface and operates within a supply voltage range of 4.5V to 5.5V. The device supports a data rate of 33.3MHz with a maximum access time of 20ns. It is housed in a 32-PLCC surface-mount package measuring 14x11.46mm. The component is designed for unidirectional bus direction applications.

Feature Summary

• Asynchronous FIFO architecture for temporary data buffering
• High-speed operation supporting up to 33.3MHz data rates
• Relay capability for signal transmission integrity
• Single-ended logic levels compatible with standard CMOS/TTL systems

Applications

• Data buffering between asynchronous clock domains
• Interface bridging between high-speed processors and slower peripherals
• Temporary storage in communication protocol converters
• System integration requiring reliable data flow control

Procurement Notes

Verify the exact suffix JG8 against official Renesas documentation to confirm pinout and electrical specifications. Confirm RoHS compliance status as historical records indicate non-compliance for this specific variant. Check current availability as the part may be discontinued or subject to limited production runs. Ensure compatibility with existing PCB footprints for 32-PLCC packages during procurement planning.

Selection Notes

Select this component when a 64K x 9 asynchronous FIFO is required for system design. Consider the 20ns access time and 33.3MHz speed for timing constraints. Evaluate the 32-PLCC package size against board space limitations. Verify that the 4.5V to 5.5V operating voltage aligns with the target system power rails before finalizing the selection.

Part Context

The 7208L20JG8 belongs to the IDT 7200 series of asynchronous FIFOs manufactured by Renesas Electronics. This series is known for providing flexible memory depth and width configurations. The 7208 variant specifically offers a 576K bit capacity, distinguishing it from other members like the 7202 or 7203 which have different memory organizations. It serves as a specialized memory solution for industrial and commercial electronic systems.
