TEMPCOMPRTC-RD
3. Kit Overview
The Temperature Compensated Real Time Clock (TC-RTC) Reference Design Kit includes an evaluation board
that utilizes a Silicon Laboratories C8051F300 Mixed Signal Microcontroller. This kit offers the following features:
Low-cost Temperature Compensated Real Time Clock and Calendar
56-byte General Purpose Non-Volatile RAM
RS-232 Serial Interface
Optional SMBus/I 2 C Interface
Full source code for the TC-RTC firmware is included
The board is pictured in Figure 1, with the major components labeled. The MCU on the board is preloaded with the
TC-RTC firmware with UART interface, and the included CD-ROM contains the firmware source code. More
information about this reference design can be found in “AN293: Temperature Compensated Real Time Clock
Reference Design Programmer’s Guide.” The following sections demonstrate the features of this reference design.
