MicroThe STC8F2K32S4-28I-LQFP32 is an 8-bit microcontroller manufactured by STC Micro. It is in a package type referred to as LQFP-32 RoHS, which stands for low-profile quad flat package – 32 pins with Restriction of Hazardous Substances (RoHS) compliance. It contains 2 Kbytes of program Flash memory, 28 I/O pins, 1Kbyte of operating SRAM memory, and a 16-bit prescaler for timer 0 and timer 1. It has 4-channel 8-bit ADC, 3-channel PWM, 4-channel 16-bit timers, and 2 UART ports for serial communication. The STC8F2K32S4-28I-LQFP32 can be powered by either a 5V DC voltage or 3.3V DC voltage and is capable of operating up to a maximum frequency of 8MHz. It also features other peripherals, such as SPI bus, I2C bus, and a watchdog timer.
