Higher Baud Rate using SmartCard with Clock in ISO7816-3

[PJose.4]

Hi @Channel

I am trying to interface SAM Module TDA8026 with STM32U585 and have few doubts

1. Any support in this regard(Reference, example library etc)
2. As per the ISO 7816 standard - maximum frequency of clk should be less than 5MHz with default fi and di values. with this configuration maximum speed attaniable is 9600(With system clock 160Mhz and Clock UART will be 5 Mhz). How can i acheive higher baud rate(like 1 Mbps) and can it be programmed through software to a particular range like(9kbps to 1 Mbps). If yes, please provide some detailed information on how to implement the same.
3. Any reference document on the working of SMARTCARD_WITH_CLOCK - USART in the STM HAL Library.

Thanks for the support

Thanks and Regards

Philip

or on ST web site
