Hi everybody

I want to make a smartcard with sm32. I know stm32 has smartcard interface using Uart peripheral. however all the documents I have seen, used stm32 as smartcard reader. is it possible to use stm32 as a smartcard mcu? and can you guide me how can I do this? 

Thanks

Hello,

Have a look to the 

SMARTCARD 

example provided within the firmware package describes a firmware Smartcard Interface based on the USART peripheral, this can help you to develop an application using the USART peripheral in smartcard mode.

The working example for

STM3210E_EVAL project: 

STM32Cube_FW_F1_V1.4.0\Projects\STM3210E_EVAL\Examples\SMARTCARD\SMARTCARD_T0

This example is based on the

http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32-standard-peripheral-libraries-expansions/stsw-stm32011.html

'Smartcard interface with the STM32F101xx and STM32F103xx' application note.

Thank you Imen for your helpful response.

It also uses stm32 as an smart card reader. As I stated before, I want to use stm32 as a smart card not a smart card reader. I will use stm32 inside an smart card and I want to interface with a reader like acr38u. I want to know is it possible for stm32 to interface with a reader in the smartcard mode of the UART?

thanks

I expect it could.

I seem to recall a version of the STM32L162 was available in a card form-factor once upon a time, but there are likely export controls on those types of devices.
