The K40 family is the cost-optimized version of the K42, adding a 12-bit ADC (vs 10-bit on older K22) and removing some advanced features. The 12-bit ADC provides 4096 quantization levels with hardware oversampling up to 256x for effective 16-bit resolution, and automatic threshold comparison with interrupt on out-of-range. Two DAC channels (8-bit each) provide analog output capability. The CTMU (Charge Time Measurement Unit) enables capacitive touch sensing with 24 channels and precision time measurement. Five CCP\/ECCP modules support capture, compare, and PWM with up to 10-bit resolution and dead-band control for motor driving. Two EUSARTs support LIN and IrDA. Two MSSP modules provide SPI and I2C with address masking for multi-slave systems. The hardware limit controller (HLC) monitors ADC results and can shut down PWM outputs without CPU intervention, critical for motor protection. The nanoWatt XLP technology provides 20nA sleep current. The device includes 256 bytes of data EEPROM and a 16-level hardware interrupt priority system. The -I\/PT suffix specifies industrial temperature (-40C to +85C), TQFP-44.","pin_description":" | Pin<\/th> | Name<\/th> | Type<\/th> | Function<\/th><\/tr> |
