Description:The 72V3672 Bidirectional SyncFIFO (clocked) memory is a 3.3V version of the 723672. Two independent 8K x 36 dual-port SRAM FIFOs on board each chip buffer data in opposite directions. The clocks for each port are independent of one another and can be asynchronous or coincident. The enables for each port are arranged to provide a simple bidirectional interface between microprocessors and/or buses with synchronous control.
Renesas provides a recommended PCB layout guide in their application note (APN) documents, which includes thermal vias, thermal pads, and heat sink recommendations to ensure optimal thermal performance.
The 72V3672L10PFG has a built-in overcurrent protection feature, but it's recommended to add external overcurrent protection circuitry, such as a fuse or a current sense resistor, to ensure reliable operation and prevent damage.
Renesas recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, depending on the specific application and operating conditions, to ensure stable input voltage and reduce noise.
To ensure EMC compliance, follow Renesas' guidelines for PCB layout, component selection, and shielding, and consider using additional EMC filters or chokes if necessary, depending on the specific application and regulatory requirements.
The 72V3672L10PFG has an operating temperature range of -40°C to 125°C, but it's recommended to derate the device's performance and consider thermal management strategies for high-temperature applications.
