STC8A8K64D4 Series Manual
➢ Analog peripherals
✓
15 channels (channel 0 to channel 14) ultra high speed ADC which supports
800K(800,000 ADC conversions per second)
✓
Channel 15 of ADC is used to test the internal reference voltage. (The default internal reference voltage is 1.19V when the chip
is shipped)
✓
A set of comparator (the CMP+, CMP+_2, CMP+_3 and all ADC input ports can be selected as the positive terminal of the
comparator, the CMP- and the internal 1.19V reference source can be selected as the negative terminal of the comparator, so the
comparator can be used as a multi-channel comparator for time division multiplexing)
✓
DAC: 8 channels advanced PWMs timers can be used as 8 channels DAC, 4-channel PCA can be used as 4-channel DAC
➢ GPIO
✓
Up to 59 GPIOs: P0.0~P0.7, P1.0~P1.7, P2.0~P2.7, P3.0~P3.7, P4.0~P4.4, P5.0~P5.5, P6.0~P6.7, P7.0~P7.7
✓
4 modes for all GPIOs: quasi_bidirectional mode, push-pull outputmode, open drain mode, high-impedance input mode
✓
Except for P3.0 and P3.1, all other I/O ports are in a high-impedance state after power-on. User must configure the I/O ports
mode before using them. In addition, the internal 4K pull-up resistor of every I/O can be enabled independently.
➢ Package
