With on-chip power-on reset, V
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 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 1.8 to 3.8 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 VIO + 2.0 V. The C8051F960/2/4/6/8 are
available in a 76-pin DQFN package and an 80-pin TQFP package. The C8051F961/3/5/7/9 are available
in a 40-pin QFN package. All package options are lead-free and RoHS compliant. See Table 2.1 for order-
ing information. Block diagrams are included in Figure 1.1 through Figure 1.16.
