I SD24_B negative analog input for converter 6(2) (not available on F676xA, F674xA devices)

Analog ground supply

Analog power supply

Analog power supply selected between AVCC, AUXVCC1, AUXVCC2. Connect recommended

capacitor value of CVSYS

Auxiliary power supply AUXVCC2

Auxiliary power supply AUXVCC1

Digital power supply selected between DVCC, AUXVCC1, AUXVCC2. Connect recommended

capacitor value of CVSYS.

Digital power supply

Digital ground supply

Regulated core power supply (internal use only, no external current loading)

27 I/O Input terminal for crystal oscillator

28 I/O Output terminal for crystal oscillator

Auxiliary power supply AUXVCC3 for backup subsystem

30 I External time capture pin 1 for RTC_C

31 I External time capture pin 0 for RTC_C

P1.5/SMCLK/CB0/A5

General-purpose digital I/O with port interrupt

32 I/O SMCLK clock output

Comparator_B input CB0

Analog input A5 - 10-bit ADC

(1) I = input, O = output

(2) It is recommended to short unused analog input pairs and connect them to analog ground.

(3) The pins VDSYS1 and VDSYS2 must be connected externally on board for proper device operation.

(4) VCORE is for internal use only. No external current loading is possible. VCORE should only be connected to the recommended

capacitor value, CVCORE.
