Pin Descriptions
Pin
Name
Type
Function
1
VSS
Power
Ground, 0 V. All VSS pins and TEST (VSS) pin must be connected together.
2
VREG
Power
Output of internal Voltage Regulator, 2.2 V nominal. This pin can power external loads
of <5 mA. If load is “noisy” it requires a bypass capacitor. May be left unconnected or
used as a high logic level signal for CLKSEL pin (see below).
3
VDD
Power
Main power supply, +2.3 to +5.5 V.
4
VBAK
Power
Backup power supply for real-time clock, +2.3 to +5.5 V (+1.8 to +5.5 V typical). This
voltage can be higher or lower than VDD. Connect a backup battery or backup
capacitor (with external recharge circuit). Connect to VDD if not used.
5
XIN
Analog In
6
XOUT
Analog Out
Oscillator pins for optional external low frequency crystal, typically 32.768 kHz crystal
with nominal 12.5 pF load capacitance. Keep open or connect to VSS if not used.
7
CLKSEL
Digital In
Must be tied to VREG
8
VSS
Power
Ground, 0 V. All VSS pins and TEST (VSS) pin must be connected together.
9
NC
Not connected - reserved
10
NC
Not connected - reserved
11

12 TEST (VSS)
Digital In
Factory test enable. All VSS pins and TEST (VSS) pin must be connected together.
13
CLK32
Digital Out
Buffered internal 32.768 kHz clock, derived according to the CLKSEL pin setting. This pin
uses backup power for the buffer when VDD is not present. When driving high, this signal
is either at VBAK or VDD (if VDD is higher than the reset threshold). When enabled, this
signal runs continuously independent of CLKOUT activity. Minimize the external load to
reduce power consumption during backup operations. When disabled, this pin is driven
to VSS. Keep open if not used.
14
IO/INT
I/O
Serial communications interface and interrupt output pin. This pin is internally weakly
pulled to the opposite of the programmed interrupt polarity. For example, if interrupt is
programmed to be active low, this pin is weakly pulled to VDD when inactive. Keep
open if not used.
15
CLKIN
Digital In
Clock activity sense input. Used to detect when the target microcontroller enters stop
mode (which disables its clock). Connect to the microcontroller’s clock output or
oscillator output pin. Connect to VSS when not used. CLKIN must not be left open.
16
CLKOUT
Digital Out
Programmable high frequency clock output. Connect to the target microcontroller’s clock
input or oscillator input pin. Keep open if not used.
