10 ADC sample rate increase to 500 ksps SAR clock increased to 8.33 MHz Gain setting of 0.5x now available Single ended inputs only External conv

11 More voltage reference options Calibrated temperature sensor Porting considerations AMX0CN register should always be written as 11111b Defaul

12Supply Voltage Considerations (1 of 2) Process technology change and second voltage regulator added VDDoutput now 3.45 V instead of 3.3 V Second

13Supply Voltage Considerations (2 of 2) VIOconsiderations VIO≤ VDD Not all packages have a VIOpin Reset can be pulled up to VDD VPPconsideration

14Low Power Modes and Clocking Suspend mode operation turns off the internal oscillator C8051F34A requires USB resume signaling or VBUS interrupt to

15Additional Features SMBus/I2C Optional hardware address recognition and automatic ACK• Reduces firmware overhead Port match Allows system events

20Attaching a Daughter Card Development can start using the flash-based C8051F34A Plug the C8051T62x EDB emulation daughter board into the motherboa

21Making Mother Board Connections Verify jumper settings with the DK user’s guide Connect USB cable to the mother board P5 Provides code download a

22Verify Tool Flow Build a sample project Open T620_Blinky_C.wsp project using the Silicon Labs IDE• Found in the C:\Silabs\MCU\Examples\C8051T620_1

23Blinking the LED When the application is running LED1 should be blinking Code can be modified and downloaded multiple times using the C8051F34ARun

24Developing the Application Make modifications to the example code to provide the required system functionality (recommended) or write the applicati

25Porting the Application to the OTP Device Once the application code has been completed on the flash-based MCU migrate the project to the OTP versio

26Using the Oscillator Internal oscillator is now 48 MHz instead of 12 MHz For backward compatibility the clock multiplier registers remain although

27Applications with an ADC Voltage reference options can be optimized for dynamic range C8051T62x/32x is single ended and doesn’t have a mux for the

28Measuring Temperature Temperature sensor measurements differ between the two families Transfer function of the temperature sensors is different O
