== XCN15034 and power-off sequence ==
On 29th September 2015 Xilinx released a Product Change Notice indicating new power on/off requirements about Zynq components.
A specific analysis has been undertaken with the help of Xilinx technical support to verify the compliance of Bora with respect to the new requirements. This activity has led to the following recommendation: in order to prevent situations that might not fulfill such requirements, 3.3VIN off ramp speed must not exceed 77V50 V/sms.
For more details about this matter, please refer to AR #65240<ref name="AR65240">http://www.xilinx.com/support/answers/65240.html</ref> and XCN15034<ref name="XCN15034">http://www.xilinx.com/support/documentation/customer_notices/xcn15034.pdf</ref>.
