Unlock Secured STM8S903F3 Microcontroller Memory Firmware from its program flash and data eeprom, the file format will be heximal and fuse bit of mcu will be broken by focus ion beam, and the protective microprocessor stm8s903f3 software will be readout;
STM8S20xxx performance line products contain a 10-bit successive approximation A/D converter (ADC2) with up to 16 multiplexed input channels and the following main features:
Input voltage range: 0 to VDDA
Dedicated voltage reference (VREF) pins available on 80 and 64-pin devices
Conversion time: 14 clock cycles
Single and continuous modes
External trigger input
Trigger from TIM1 TRGO
End of conversion (EOC) interrupt
The beCAN controller (basic enhanced CAN), interfaces the CAN network and supports the CAN protocol version 2.0A and B. It has been designed to manage a high number of incoming messages efficiently with a minimum CPU load.
For safety-critical applications the beCAN controller provides all hardware functions to support the CAN time triggered communication option (TTCAN). The maximum transmission speed is 1 Mbit.
Three transmit mailboxes
Configurable transmit priority by identifier or order request
Time stamp on SOF transmission
8-, 11- and 29-bit ID
One receive FIFO (3 messages deep)
Software-efficient mailbox mapping at a unique address space
FMI (filter match index) stored with message
Configurable FIFO overrun
Time stamp on SOF reception
Six filter banks, 2 x 32 bytes (scalable to 4 x 16-bit) each, enabling various masking configurations, such as 12 filters for 29-bit ID or 48 filters for 11-bit ID
Filtering modes:
Mask mode permitting ID range filtering
ID list mode
Time triggered communication option
Disable automatic retransmission mode
16-bit free running timer
Configurable timer resolution
Time stamp sent in last two data bytes
