The STC IAP15W4K61S4-30I-LQFP64S is a Low Power Consumption RoHS compliant 61KB 4KB FLASH 62 51Series LQFP-64 (10x10)Microcontroller Units (MCUs/MPUs/SOCs). It features High-performance 1T CPU core architecture and large memory, and also takes advantage of the system management bus (SMBus) for an improved device monitoring and configuration. Its power-saving mode allows it to consume only 185 µA/MHz, while other features include a true microsecond timer, four 16-bit PWMs, a ST12 Flash controller, an embedded utilities with STD I/O, an LCD controller, mobile DMA protocol, USB Host, WiFi function, power over Ethernet function, and low voltage drop regulators. It also utilizes energy efficient power-saving features, such as standby current reduction, low operating voltage, and deep sleep. Additionally, it supports a wide range of industrial standards, including SPI, I2C, UART, SDIO/USB, CAN, Ethernet, and ZigBee/Bluetooth.
