The C8051F302-GS is a low power, high-performance 8-bit microcontroller from Silicon Labs. This product is based on the 8051 microcontroller core and includes: a multi-source clock, 4 kB Flash, 128 bytes of RAM, 32 I/O lines, 2 16-bit timer/counters, a UART, an SPI port, and an I2C port, among other features. The integrated voltage regulator allows the microcontroller to operate from a single 3–5.5 V supply, and the low-power standby mode reduces current consumption to reduce power consumption. This device is ideal for applications that require reliable performance, low cost, and a wide variety of available features.
