C8051F330/1/2/3/4/5 devices are 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.
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 with-
out occupying 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 in
20-pin QFN packages (also referred to as MLP or MLF packages). Lead-free (RoHS compliant) packages
are also available. See Table 1.1 for ordering part 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.
