1. System Overview
C8051T622/3 and C8051T326/7 devices are fully integrated mixed-signal System-on-a-Chip MCUs. High-
lighted features are listed below. Refer to Table 2.1 for specific product feature selection and part ordering

C8051T326/7 devices are truly stand-alone System-on-a-Chip solutions. User software has complete con-
trol of all peripherals, and may individually shut down any or all peripherals for power savings.
Code written for the C8051T622/3 and C8051T326/7 family of processors will run on the C8051F34A
Mixed-signal ISP Flash microcontroller, providing a quick, cost-effective way to develop code without
requiring special emulator circuitry. The C8051T622/3 and C8051T326/7 processors include Silicon Labo-
ratories’ 2-Wire C2 Debug and Programming interface, which 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 of memory, viewing and modification of special function 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-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. An additional internal LDO is used to supply the processor core voltage at 1.8 V. The
Port I/O and RST pins are tolerant of input signals up to 5 V. The C8051T622/3 are available in 24-pin QFN
packaging and the C8051T326/7 are available in 28-pin QFN packaging. See Table 2.1 for ordering infor-
mation. A block diagram is shown in Figure 1.1.
