The STC15W4K32S4-30I-LQFP64S is a 64-pin low-power 8-bit single-chip microcontroller (MCU) designed and manufactured by STC (STCMicro). This MCU features an enhanced architectural design which combines a low-power core CPU, Flash memory, SRAM, and I/O ports. It is housed in a 64-pin LQFP (Leadless Quad Flat Pack) package measuring 10 mm x 10 mm x 0.5 mm. This MCU is RoHS-compliant, meaning that it meets European Union environmental standards by limiting the use of hazardous substances. The processing speed of this MCU is up to 30 MIPS (million instructions per second). It also features a powerful peripherals, including UART, CAN, I2C, SPI, and ADC ports. The STC15W4K32S4-30I-LQFP64S is suitable for industrial, automotive, and home automation applications.
