ST72311
1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST72311 HCMOS Microcontroller Unit (MCU)
is a member of the ST7 family. The device is
based on an industry-standard 8-bit core and fea-
tures an enhanced instruction set. The device is
normally operated at a 16 MHz oscillator frequen-
cy. Under software control, the ST72311 may be
placed in either Wait, Slow or Halt modes, thus re-
ducing power consumption. The enhanced in-
struction set and addressing modes afford real
programming potential. In addition to standard
8-bit data management, the ST72311 features
true bit manipulation, 8x8 unsigned multiplication
and indirect addressing modes on the whole mem-
ory. The device includes a low consumption and
fast start on-chip oscillator, CPU, program memo-
ry
(ROM/OTP/EPROM
versions),
RAM,
44
(ST72311N) or 32 (ST72311J) I/O lines, a Low
Voltage Detector (LVD) and the following on-chip
peripherals: Analog-to-Digital converter (ADC)
with 8 (ST72311N) or 6 (ST72311J) multiplexed
analog inputs, industry standard synchronous SPI
and asynchronous SCI serial interfaces, digital
Watchdog, two independent 16-bit Timers, one
featuring an External Clock Input, and both featur-
ing Pulse Generator capabilities, 2 Input Captures
and 2 Output Compares (only 1 Input Capture and
1 Output Compare on Timer A).
