The is a highly integrated mixed-signal 8-bit ISP Flash Microcontroller featuring a powerful 8051 core with 50MHz performance. This analog-intensive microcontroller features a 16-bit 8-channel 1ksps ADC, a 8-bit 2-channel DAC, a comparator and an on-chip temperature sensor. The C8051F352 also offers 8kB Flash, 0.75kB RAM along with I²C, SPI, UART communication interfaces and 4 x 16-bit timers. With on-chip POR, VDD monitor, watchdog timer, a ±2% internal oscillator and high analog integration. This device is truly stand-alone system-on-a-chip solutions. The flash memory can be reprogrammed even in-circuit, providing non-volatile data storage and also allowing field upgrades of the 8051 firmware. User software has complete control of all peripherals and may individually shut down any or all peripherals for power savings.
