C8051F330/1/2/3/4/5 devices are fully integrated mixed-signal System-on-a-Chip MCUs. Highlighted featuresare listed below. Refer to Table 1.1 for specific product feature selecTIon.• High-speed pipelined 8051-compaTIble microcontroller core (up to 25 MIPS)• In-system, full-speed, non-intrusive debug interface (on-chip)• True 10-bit 200 ksps 16-channel single-ended/differenTIal ADC with analog mulTIplexer• 10-bit Current Output DAC• Precision programmable 25 MHz internal oscillator• Up to 8 kB of on-chip Flash memory—512 bytes are reserved• 768 bytes of on-chip RAM• SMBus/I2C, Enhanced UART, and Enhanced SPI serial interfaces implemented in hardware• Four general-purpose 16-bit timers• Programmable Counter/Timer Array (PCA) with three capture/compare modules and Watchdog Timerfunction• On-chip Power-On Reset, VDD Monitor, and Temperature Sensor• On-chip Voltage Comparator• 17 Port I/O (5 V tolerant)With on-chip Power-On Reset, VDD monitor, Watchdog Timer, and clock oscillator, theC8051F330/1/2/3/4/5 devices are truly stand-alone System-on-a-Chip solutions. The Flash memory canbe reprogrammed even in-circuit, providing non-volatile data storage, and also allowing field upgrades ofthe 8051 firmware. User software has complete control of all peripherals, and may individually shut downany or all peripherals for power savings.The on-chip Silicon Labs 2-Wire (C2) Development Interface allows non-intrusive (uses no on-chipresources), full speed, in-circuit debugging using the production MCU installed in the final application. Thisdebug logic supports inspection and modification of memory and registers, setting breakpoints, singlestepping, run and halt commands. All analog and digital peripherals are fully functional while debuggingusing C2. The two C2 interface pins can be shared with user functions, allowing in-system debugging withoutoccupying package pins.Each device is specified for 2.7 to 3.6 V operation over the industrial temperature range (–40 to +85 °C).The Port I/O and RST pins are tolerant of input signals up to 5 V. The C8051F330/1/2/3/4/5 are available in20-pin QFN packages (also referred to as MLP or MLF packages) and the C8051F330 is available in a 20-pin PDIP package. Lead-free (RoHS compliant) packages are also available. See Table 1.1 for orderingpart numbers. Block diagrams are included in Figure 1.1, Figure 1.2, Figure 1.3, Figure 1.4, Figure 1.5,and Figure 1.6.
