C8051F340/1/2/3/4/5/6/7/8/9/A/B/C/D devices are truly stand-alone System-on-a-Chip solutions. The
Flash memory can be reprogrammed 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 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. C8051F340/1/2/3/
4/5/6/7/8/9/A/B/C/D devices are available in 48-pin TQFP, 32-pin LQFP, or 32-pin QFN packages. See
Table 1.1, “Product Selection Guide,” on page 18 for feature and package choices.
