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.

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 Table 14.

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 Table 15).
