C8051F300/1/2/3/4/5 devices are fully integrated mixed-signal System-on-a-Chip MCUs. Highlighted features are
listed below. Refer to Table 1.1 on page 12 for specific product feature selection.
With on-chip Power-On Reset, VDD monitor, Watchdog Timer, and clock oscillator, the C8051F300/1/2/3/4/5
devices are truly stand-alone System-on-a-Chip solutions. The FLASH memory can be reprogrammed even in-cir-
cuit, 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.
The on-chip Silicon Labs 2-Wire (C2) Development Interface allows non-intrusive (uses no on-chip resources), full
speed, in-circuit debugging using the production MCU installed in the final application. This debug logic supports
inspection and modification of memory and registers, setting breakpoints, single stepping, run and halt commands.
All analog and digital peripherals are fully functional while debugging using C2. The two C2 interface pins can be
shared with user functions, allowing in-system debugging without occupying package pins.
Each device is specified for 2.7 V-to-3.6 V operation over the industrial temperature range (-45°C to +85°C). The
Port I/O and /RST pins are tolerant of input signals up to 5 V. The C8051F300/1/2/3/4/5 are available in the 11-pin
MLP package shown in Figure 4.2.
