Description
RST/PD/
38
IN-5VT
Master reset and Power down. Schmitt trigger input.
RST/PD/ should be held low during at least 10ms after power is
applied.
On the rising edge of RST/PD/ the chip enters its initialization
routine.
When RST/PD/ is low, Power-down is active: 8-bit port data
lines are High-Z. IRQ is set to 0. The PLL is stopped and supply
voltage is removed from analog and digital core. To exit from
power down, RST/PD/ must be set to VD33.
X1-X2
39, 40
-
9.6 MHz or 12 MHz crystal connection. An external clock can
also be used on X1.
XDIV
47
IN
System clock divider.
-
When grounded, it allows using 9.6MHz crystal
-
When connected to VD33, it allows using 12MHz crystal
OUTVC12
34
PWR
3.3V to 1.2 V regulator output. The built-in regulator gives 1.2V
for internal use only (core supply).
4.7µF or 10µF Decoupling capacitor must be connected
between OUTVC12 and GND.
TEST
37
IN
Test pin with a built-in pull-down. It should be grounded or left
open for normal operation.
NC
17, 19, 21-23;
43, 44
-
Not connected pins.
