Note:
The temperature result measured from STLM75M2F would be a little higher than the
ambient temperature due to the power dissipation of the components on the board.
2.14 Smartcard
STMicroelectronics smartcard interface chip ST8024L is used on the STM32091C-EVAL
evaluation board for asynchronous 1.8 V, 3 V and 5 V smartcards. It performs all supply
protection and control functions based on the connections with the STM32F091VCT6 listed
in
Smartcard operates correctly when VDD > 2.7 V.
2.15 CAN
STM32091C-EVAL evaluation board supports one channel of CAN2.0A/B compliant CAN
bus communication based on 3.3 V CAN transceiver. The high-speed mode, standby mode
and slope-control mode are available and selectable by setting JP3 (see
).
