C8051F98x 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 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
without occupying package pins.
Each device is specified for 1.8 to 3.6 V operation over the industrial temperature range (–40 to +85 °C).
The Port I/O and RST pins are powered from the supply voltage. The C8051F99x-C8051F98x devices are
available in 20-pin or 24-pin QFN or 24-pin QSOP 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 through
Figure 1.9.
