C8051F54x 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.
The devices are specified for 1.8 V to 5.25 V operation over the automotive temperature range (–40 to
+125 °C). The C8051F540/1/4/5 devices are available in 32-pin QFP and QFN packages and the
C8051F542/3/6/7 devices are available in 32-pin QFN packages. All package options are lead-free and
RoHS compliant. See Table 2.1 for ordering information. Block diagrams are included in Figure 1.1 and
Figure 1.2.
