– Reset by reset pin. The default function of P5.4 is the I/O port. The P5.4 pin can be set as the reset pin while ISP download. (Note: When the P5.4 pin is set as the reset pin, the reset level is low.)
– Watch dog timer reset
– Low voltage detection reset. 4 low voltage detection levels are provided, 2.0V, 2.4V, V2.7,V3.0
• Software reset

Digital peripherals
• 5 16-bit timers: timer0, timer1, timer2, timer3, timer4, where the mode 3 of timer 0 has the Non-Maskable Interrupt (NMI in short) function. Mode 0 of timer 0 and timer 1 is 16-bit Auto-reload mode.
• 4 high speed UARTs: UART1, UART 2, UART 3, UART 4, whose maximum baudrate may be FOSC/4.
• 8 channels/2 groups of enhanced PWMs, which can realize control signals with dead time, and support external fault detection function. In addition, it also supports 16-bit timers, 8 external interrupts, 8 external captures and pulse width measurement functions.
• SPI: Master mode, slave mode or master/slave automatic switch mode are supported.
• I2C: Master mode or slave mode are supported.
• MDU16: Hardware 16-bit Multiplier and Divider which supports 32-bit divided by 16-bit, 16-bit divided by 16-bit, 16-bit multiplied by 16-bit, data shift, and data normalization operations.
• USB: USB2.0/USB1.1 compatible with full speed USB, 6 two-way endpoints, support 4 endpoint transmission modes (control transmission, interrupt transmission, batch Quantum and synchronous transfers), each endpoint has a 64 byte buffer
• RTC: Support year, month, day, hour, minute, second, sub-second (1/128 second). And supports clock interrupt and a set of alarm clocks (Note: A version of the chip does not have this function)
• I/O port interrupt: All I/Os support interrupts, each group of I/O interrupts has an independent interrupt entry address, all I/O interrupts can support 4 types interrupt mode: high level interrupt, low level interrupt, rising edge interrupt, falling edge interrupt. (Note: The I/O port interrupts of the STC8H3K64S2 series A version of the chip cannot wake up CPU from powerdown. The I/O port interrupts of the B version chip can wake up CPU from power-down, but only have one level of interrupt priority)
• DMA: support Memory-To-Memory, SPI, UART1TX/UART1RX, UART2TX/UART2RX, UART3TX/UART3RX, UART4TX/UART4RX, ADC(Automatically calculates the average of multiple ADC results), LCM (Note: A version of the chip does not have this function)
• LCM (TFT color screen) dirver: support 8080 and 6800 interface, and support 8-bit and 16-bit data width (Note: A version of the chip does not have this function)
– 8 bits 8080 data bus: 8 bits data lines (TD0~TD7), READ signael (TRD)c WRITE signal (TWR), RS line (TRS)
– 16 bits 8080 bus: 16 bits data lines (TD0~TD15), READ signael (TRD)c WRITE signal (TWR), RS line (TRS)
– 8 bits 6800 bus: 8 bits data lines (TD0~TD7), enable signal (TE) , READ and WRITE signal (TRW) , RS line (TRS)
– 16 bits 6800 bus: 16 bits data lines (TD0~TD15), enable signal (TE) , READ and WRITE signal (TRW) , RS line (TRS)
– Note: If you use 8-bit data lines to control the TFT screen, you generally need TD0~D7, TRD/TWR/TRS, 11 data and control lines, plus 2 common I/Os to control chip selection and reset (many TFT color screen chip selections and reset manufacturer has carried out automatic processing, does not need software control)
Analog peripherals
• Ultra high speed ADC which supports 12-bit precision 12 channels analog-to-digital convertor (channel 0 to channel 2, channel 6 to channel 14. No channel 3 and channel 5 because P1.3, P1.4 and P1.5 do not exist ). The maximum speed can be 800K(800K 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)
• Comparator. A set of comparator (For A version of the chip, the CMP+ port and all ADC input ports can be selected as the positive terminal of the comparator, the CMP- port and the internal reference voltage 1.19V can be selected as the negative terminal of the comparator. For B version of the chip, the CMP+, CMP+_2, CMP+_3 port and all ADC input ports can be selected as the positive terminal of the comparator, the CMP- port and the internal reference voltage 1.19V 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
GPIO
• Up to 61 GPIOs: P0.0~P0.7, P1.0~ P1.7(no P1.2), P2.0~P2.7, P3.0~P3.7, P4.0~P4.7, P5.0~P5.4, P6.0~P6.7, P7.0~P7.7
• 4 modes for all GPIOs: quasi-bidirectional mode, push-pull output mode, 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 set the I/O ports mode before using them. In addition, the internal 4K pull-up resistor of every I/O can be enabled independently.
