SILICON LABS  C8051F230-GQ  微控制器, 8位, 混合信号, C8051F2xx, 25 MHz, 8 KB, 256 Byte, 48 引脚, TQFP

The is a highly integrated mixed-signal 8-bit ISP Flash Microcontroller featuring a powerful 8051 core with 25MHz performance. The MCU offers 8kB flash, 0.25kB RAM along with SPI, UART communication interfaces and 3 x 16-bit Timers. On-chip analog features include an ADC and 2 comparators. With on-chip power-on reset, VDD monitor, watchdog timer, a ±20% internal oscillator. The flash memory can be reprogrammed even in-circuit, providing nonvolatile data storage and also allowing field upgrades of the 8051 firmware. On-board JTAG debug support allows non-intrusive uses no on-chip resources, full speed, in-circuit debug using the production MCU installed in the final application. This debug system supports inspection and modification of memory and registers, setting breakpoints, watchpoints, single stepping, run and halt commands. All analog and digital peripherals are fully functional when emulating using JTAG.
