Serial interface coverage for sensor and actuator links
On-chip connectivity includes I²C, SPI, and UART/USART — the three serial buses most commonly used for external ADCs, digital sensors, displays, and radio modules. IrDA and LINbus are also present, covering infrared communication and automotive local interconnect. 21 general-purpose I/O lines in the 28-TSSOP package leave room for a 10-channel 10-bit ADC, PWM outputs, and a watchdog timer.
Industrial temperature rating and supply range
Internal oscillator keeps the BOM count low.
For a BOM freeze, this is a stable line. Small-quantity orders are accommodated.
