monitor, Watchdog Timer, and clock oscillator, the C8051F41x devices
are truly standalone 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 Laboratories 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 programming
and debugging without occupying package pins.
Each device is specified for 2.0-to-2.75 V operation (supply voltage can be up to 5.25 V using on-chip reg-
ulator) over the industrial temperature range (–45 to +85 °C). The C8051F41x are available in 28-pin QFN
(also referred to as MLP or MLF) or 32-pin LQFP packages.
