ST9291
GENERAL DESCRIPTION
The ST9291 is a ROM member of the ST9 family of
microcontrollers, completely developed and pro-
duced by SGS-THOMSON Microelectronics using
a proprietary n-well HCMOS process.
The ROM parts are fully compatible with their
EPROM and OTP (One-Time Programmable) ver-
sions, which may be used for the prototyping and
pre-production phases of development.
The nucleus of the ST9291 is the advanced ST9
Core which includes the Central Processing Unit
(CPU), the Register File, a 16-bit Timer/Watchdog
with 8-bit Prescaler, a Serial Peripheral Interface
supporting S-bus, I2C-bus and IM-bus Interface,
plus two 8-bit I/O ports. The Core has independent
memory and register buses allowing a high degree
of pipelining to add to the efficiency of the code
execution speed of the extensive instruction set.
The powerful I/O capabilities demanded by micro-
controller applications are fulfilled by the ST9291
with up to 32/42 I/O lines dedicated to digital In-
put/Output. These lines are grouped into up to six
I/O Ports and can be configured on a bit basis un-
der software control to provide timing, status sig-
nals, timer inputs and outputs, analog inputs, ex-
ternal interrupts, OSD (On Screen Display) output
and serial or parallel I/O.
Three basic memory spaces are available to sup-
port this wide range of configurations: Program
Memory, Data Memory and the Register File,
which includes the control and status registers of
the on-chip peripherals.
The human interface is provided by the On Screen
Display module, this can produce up to 15 lines of
up to 34 characters from a ROM defined 128 char-
acter set. The 9x13 character can be modified by 4
different pixel sizes, with character rounding, and
formed into words with colour and format attrib-
utes.
A 14-bit VS (Voltage Synthesis) output using the
PWM (Pulse Width Modulation)/BRM (Bit Rate
Modulation) is present to generate tuning voltages
for low-mid range TV set applications. The tuning
voltage is output on one of two separate output
pins.
A 16-bit Slice Timer with an 8-bit Prescaler is also
present.
