ST72371/ST72372
1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST72371/ST72372 HCMOS Microcontroller
Units are members of the ST7 family. These devic-
es are based on an industry standard 8-bit core
and feature an enhanced instruction set. The proc-
essor runs with an external clock up to 24 MHz
with a 5.5V supply. Under software control the
ST72371/ST72372 can be placed in WAIT, SLOW
or HALT modes thus reducing power consump-
tion. The enhanced instruction set and addressing
modes afford real programming potential.
In addition to standard 8-bit data management the
ST7 features true bit manipulation, 8x8 unsigned
multiplication and indirect addressing modes on
the whole memory.
The devices include an on-chip oscillator, CPU,
16K bytes program memory, 512 bytes RAM, 23 to
32 I/O lines, a Timer with 2 Input Captures and 2
Output Compares (with 1 output pin), a 4 to 8
channel A/D Converter, an I

C multi Master, an
SCI

Serial Communications Interface, a Watch-
dog Reset, four 10-bit and one 12-bit D/A Convert-
er channels with PWM output.
