STC microcontroller STC15W201S-207S Series High Speed: 1 clock / machine cycle, enhanced 8051 core, faster than the average of 8 to 12 times 8051 ● Wide voltage: 5.5 ~ 3.8V, 2.4 ~ 3.8V (STC12LE5410AD series) ● Low power consumption Design: idle mode, the power-down mode (by external interrupts) ● Operating frequency: 0 ~ 35MHz, equivalent to an ordinary 8051: 0 ~ 420MHz --- actually be to 48MHz, the equivalent of 8051: 0 ~ 576MHz ● Clock: external crystal or the internal RC oscillator options, set ● 12K / 10K / 8K / 6K / 4K / 2K bytes of on-chip Flash program memory inside when the ISP download programming user program, endurance more than 100,000 times ● 512 bytes of on-chip RAM ● chip EEPROM data memory function ● ISP / IAP, in-system programmable / In-Application Programmable without programmer / emulator ● 10 位 ADC, 8-channel, STC12C2052AD series of 8-bit ADC. 4-channel PWM also when 4 D / A channels use ● 4 capture / compare unit (PWM / PCA / CCU), STC12C2052AD series for 2-channel --- also be used to re-achieve four timer or four external interrupts ( Support rising / falling interrupt) ● 2 16-bit hardware timer, compatible with normal 8051 timer. PCA can be implemented again 4 4 ● hardware watchdog timer (WDT) ● ● High-speed SPI communication port full-duplex asynchronous serial port (UART), is compatible with the general 8051 serial ● advanced instruction set architecture compatible with ordinary 8051 instruction set four groups 8 8 general purpose working registers (of 32 general-purpose registers) hardware multiply / divide instruction ● Universal I / O port (27/23/15 months), after reset: quasi-bidirectional / Weak Pull (8051 ordinary traditional I / O ports) can be set to four modes: quasi-bidirectional / weak pull-up on the push-pull / strong pull, only input / high impedance, open drain each I / O port drive capability are up to 20mA, but the whole chip can not exceed 55m
