1 PREAMBLE: ST72C334 VERSUS ST72E331 SPECIFICATION
New Features available on the ST72C334
ST72C334 I/O Configuration and Pinout
8
Programming and Read-out protection
New ADC with a better accuracy and conversion
time
New configurable Clock, Reset and Supply
system
New power saving mode with real time base:
Active Halt
Beep capability on PF1
New interrupt source: Clock security system
(CSS) or Main clock controller (MCC)
Same pinout as ST72E331
PA6 and PA7 are true open drain I/O ports
without pull-up (same as ST72E331)
PA3, PB3, PB4 and PF2 have no pull-up
configuration (all I/Os present on TQFP44)
PA5:4, PC3:2, PE7:4 and PF7:6 have high sink
capabilities (20mA on N-buffer, 2mA on P-buffer
and pull-up). On the ST72E331, all these pads
(except PA5:4) were 2mA push-pull pads
without high sink capabilities. PA4 and PA5
were 20mA true open drains.

New Memory Locations in ST72C334
20h: MISCR register becomes MISCR1 register
(naming change)
29h: new control/status register for the MCC
module
2Bh: new control/status register for the Clock,
Reset and Supply control. This register replaces
the WDGSR register keeping the WDOGF flag
compatibility.
40h: new MISCR2 register
