Description:The 72801 is a 256 x 9 dual synchronous (clocked) FIFO. The device is functionally equivalent to two 72201 FIFOs in a single package with all associated control, data, and flag lines assigned to separate pins. Each of the two FIFOs has a 9-bit input data port and a 9-bit output data port. The Read Clock can be tied to the Write Clock for single clock operation or the two clocks can run asynchronous of one another for dual clock operation. The 72801 architecture lends itself to many flexible configurations
Renesas provides a recommended PCB layout guide in their application note (R01AN2732EU0100) which includes thermal design considerations, such as placing thermal vias under the package and using a solid ground plane to reduce thermal resistance.
Renesas recommends a specific power sequencing scheme in their application note (R01AN2732EU0100) to ensure proper device operation. The sequence involves powering up the VCCIO and VCC cores simultaneously, followed by the VREF and VDDQ rails.
Renesas provides specific guidelines for using the 72801L10PFG8 in high-reliability and automotive applications, including requirements for temperature range, voltage tolerance, and EMI/EMC considerations, which can be found in their reliability report (Renesas Reliability Report U173E1) and automotive application notes.
Renesas provides power-saving techniques in their application note (R01AN2732EU0100), including dynamic voltage and frequency scaling, clock gating, and power gating. Additionally, the device has built-in power-saving features, such as a low-power mode and a sleep mode, which can be controlled through register settings.
Renesas provides recommended settings for the internal oscillators in their datasheet and application note (R01AN2732EU0100), including the selection of the oscillator frequency, clock source, and clock divider settings to ensure stable and accurate clock operation.
