1. System Overview
C8051F70x/71x devices are fully integrated, system-on-a-chip, capacitive sensing mixed-signal MCUs.
Highlighted features are listed below. Refer to Table 2.1 for specific product feature selection and part
ordering numbers.
With on-chip power-on reset, V
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 C8051F70x/71x processors include Silicon Laboratories’ 2-Wire C2 Debug and Programming inter-
face, which allows non-intrusive (uses no on-chip resources), full speed, in-circuit debugging using the pro-
duction MCU installed in the final application. This debug logic supports inspection of memory, viewing and
modification of special function registers, setting breakpoints, single stepping, and 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 1.8–3.6 V operation over the industrial temperature range (–45 to +85 °C). An
internal LDO is used to supply the processor core voltage at 1.8 V. The Port I/O and RST pins are tolerant
of input signals up to 2 V above the V
information. Block diagrams of the devices in the C8051F70x/71x family are shown in Figure 1.1.
