With on-chip power-on reset, VDD monitor, voltage regulator, and clock oscillator, C8051F326/7 devices
are truly stand-alone System-on-a-Chip solutions. The Flash memory can be reprogrammed in-circuit, pro-
viding 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 sav-
ings.
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 debugging with-
out occupying package pins.
Each device is specified for 2.7–5.25 V operation over the industrial temperature range (–40 to +85 °C).
For voltages above 3.6 V, the on-chip Voltage Regulator must be used. A minimum of 3.0 V is required for
USB communication. The Port I/O and RST pins are tolerant of input signals up to 5 V. C8051F326/7 are
available in two 28-pin QFN packages with different pinouts. The RoHS compliant devices are marked with
a -GM suffix in the part number. The port I/O on C8051F326 devices is powered from a separate I/O supply
allowing it to interface to low voltage logic.
