ST72E121 ST72T121
1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST72T121 HCMOS Microcontroller Unit
(MCU) is a member of the ST7 family. The device
is based on an industry-standard 8-bit core and
features an enhanced instruction set. The device
is normally operated at a 16 MHz oscillator fre-
quency. Under software control, the ST72T121
may be placed in either Wait, Slow or Halt modes,
thus reducing power consumption. The enhanced
instruction set and addressing modes afford real
programming potential. In addition to standard
8-bit data management, the ST72T121 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 (OTP/EPROM versions), RAM, 32 I/O lines, a
Low Voltage Detector (LVD) and the following on-
chip peripherals: industry standard synchronous
SPI and asynchronous SCI serial interfaces, digit-
al 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).
