continue running during stand-by mode. 16-bit Watchdog Timer with 8 bits prescaler for system reliability and integrity. CAN module compliant with the CAN specification V2.0 part B (active). The bit rate can be programmed up to 1 MBaud. Four16-bit programmable Timers with 7 bit prescaler, up to two input capture/output compare, one pulse counter function, one PWM channel with selectable frequency each. 4 channels 12-bit sigma-delta Analog to Digital Converter, single channel or multi channel conversion modes, single-shotor continuous conversion modes, sample rate1KHz (4 KHz when single channel), conversion range 0-2.5V. Three Serial Communication Interfaces (UART) allow full duplex, asynchronous, communications with external devices, independently programmable TX and RX baud rates up to 625K baud. One UART adapted to suit Smart Card interface needs, for asynchronous SC as defined by ISO 7816-3; it includes SC clock generation. Two Serial Peripheral Interfaces (SPI) allow full duplex, synchronous communicatio
ns with external devices, master or slave operation, max baud rate: 8Mb/s. One SPI may be used as Multimedia Card interface. Two I2C Interfaces provide multi-master and slave functions, support normal and fast I2C
