2. Kit Overview
The C8051F411 Evaluation Kit demonstrates some of the unique features of the C8051F41x family:
High-performance 8051 Core – Up to 50 MIPS with a 50 MHz system clock derived from the internal oscillator
and clock multiplier.
Low-voltage Operation – Can operate on a core supply voltage as low as 2.0 V.
Versatile Interfacing – Includes an internal voltage regulator that can supply up to 50 mA at 2.5 V or 2.1 V
output.
Real Time Clock – Can accurately maintain time for up to 137 years as long as the RTC peripheral is powered
by at least 1.0 V, even if the MCU core supply voltage is lost.
The C8051F411 Evaluation Board includes a USB interface that allows debugging with the Silicon Laboratories
IDE. Power for the C8051F411 board can be supplied from the batteries or the USB connection. Refer to “3.
Evaluation Board Interface” for more details.
3. Evaluation Board Interface
The user interface of the C8051F411 Evaluation Board includes an LCD and four push-buttons. There is also a
USB port for debugging and downloading to the C8051F411 target device.
3.1. LCD User Interface
The C8051F411 Evaluation Board user interface consists of an LCD screen, four buttons, and a switch. The LCD
screen displays menu choices and information to the user. The four push buttons, MENU, SELECT, UP, and
DOWN, are used to navigate the menus and make selections. The switch determines the power source for the
C8051F411 and can be used to switch between the batteries (the left position) and the USB bus (the right position).
The C8051F411 Block Diagram shown in Figure 1 shows all elements of the user interface.
When the board is powered but idle, the LCD screen will display the time in the upper left corner and cycle through
different sets of information, depending upon the operating mode of the board. Refer to “4. Evaluation Modes” for
more details on the operating modes.
The MENU button brings up the menu on the LCD display. When navigating through the menu options, pressing
this button will revert back to the beginning of the menu, and none of the changes will be saved. The menu
interface is described in “4. Evaluation Modes”.
