C8051F92x devices are truly stand-alone System-on-a-Chip solutions. The Flash memory can be repro-
grammed 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 0.9 to 1.8 V or 1.8 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 C8051F930/20 are
available in 32-pin QFN or LQFP packages and the C8051F931/21 are available in a 24-pin QFN package.
Both package options are lead-free and RoHS compliant. See Table 2.1 for ordering information. Block
diagrams are included in Figure 1.1 through Figure 1.4.
