1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST7291L CMOS Microcontroller Unit is a
member of the ST7 family of microcontrollers. The
device is based on an industry-standard 8-bit core
and features an enhanced instruction set. Oscilla-
tor frequency may be as high as 8MHz, however,
thanks to the fully static design, operation is possi-
ble down to DC. Under software control, the
ST7291L may be placed in either WAIT or HALT
modes, thus reducing power consumption.
The enhanced instruction set and addressing
modes afford real programming potential. In addi-
tion to standard 8-bit data management, the
ST7291L features bit manipulation, 8x8 unsigned
multiplication and indirect addressing modes.
The device includes a CPU, ROM, RAM, I/O, an
on-chip oscillator, a timer with output compare
system and, depending on the version, a Low Volt-
age Detection (LVD) and Carrier Frequency gen-
eration for remote control applications.
