SUPPLY AND OSCILLATOR SIGNALS
H1
1
O/Z
External H1 clock. H1 has a period equal to twice CLKIN.
S
H3
1
O/Z
External H3 clock. H3 has a period equal to twice CLKIN.
S
VDD
20
I
5-V supply for ’C31 devices and 3.3-V supply for ’LC31 devices. All must be
connected to a common supply plane.§
VSS
25
I
Ground. All grounds must be connected to a common ground plane.
X1
1
O
Output from the internal-crystal oscillator. If a crystal is not used, X1 should be left
unconnected.
X2 / CLKIN
1
I
Internal-oscillator input from a crystal or a clock
RESERVED
EMU2 EMU0
3
I
Reserved for emulation. Use pullup resistors to VDD
EMU3
1
O/Z
Reserved for emulation
S
I = input, O = output, Z = high-impedance state
S = SHZ active, H = HOLD active, R = RESET active
§ Recommended decoupling capacitor value is 0.1 F.
Follow the connections specified for the reserved pins. Use 18-k22-k pullup resistors for best results. All VDD supply pins must be connected
to a common supply plane, and all ground pins must be connected to a common ground plane.
