Electrical characteristics
5.3.16 CAN (controller area network) interface
Refer to subsubsec 5.3.12 for more details on the input/output alternate function charac-
teristics (CAN_TX and CAN_RX).
5.3.17 12-bit ADC characteristics
Unless otherwise specified, The parameters in the table below are measured using the
ambient temperature, fPCLK2 frequency and VDDA supply voltage in accordance with the
conditions of Table 10.
Note: It is recommended to perform a calibration after each power-up

1. Guaranteed by design. Not tested in production.
2. In this series of products, VREF+ is internally connected to DDA，VREF− is internally
connected to SSA.
3. fADC Maximum support 15MHz，fS Maximum support 1MHz (fPCLK2 = 60MHz，ADC
Prescaler = 4，fADC = 15MHz, TS = 1.5)
