C8051F90x 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 0.9 to 1.8 V, 0.9 to 3.6 V or 1.8 to 3.6 V operation over the industrial
temperature range (–40 to +85 °C). The Port I/O and RST pins are tolerant of input signals up to 5 V. The
C8051F91x-C8051F90x devices are available in 24-pin QFN or QSOP packages. Both package options
are lead-free and RoHS compliant. See Table 2.1for ordering information. Block diagrams are included in
Figure 1.1 through Figure 1.4.
