With on-chip Power-On Reset,
C8051F330D devices are truly stand-alone System-on-a-Chip solutions. The Flash memory can be repro-
grammed 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 2.7 V-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 C8051F330/1 are available in a 20-
pin MLP package and the C8051F330D is available in a 20-pin DIP package. Block diagrams are included
in Figure 1.1 and Figure 1.2.
