1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST72C171 is a member of the ST7 family of
Microcontrollers. All devices are based on a com-
mon industry-standard 8-bit core, featuring an en-
hanced instruction set.
The ST72C171 features single-voltage FLASH
memory with byte-by-byte In-Situ Programming
(ISP) capability.
Under software control, the device can be placed
in WAIT, SLOW, or HALT mode, reducing power
consumption when the application is in idle or
standby state.
The enhanced instruction set and addressing
modes of the ST7 offer both power and flexibility to
software developers, enabling the design of highly
efficient and compact application code. In addition
to standard 8-bit data management, all ST7 micro-
controllers feature true bit manipulation, 8x8 un-
signed multiplication and indirect addressing
modes The device includes a low consumption
and fast start on-chip oscillator, CPU, Flash pro-
gram memory, RAM, 22 I/O lines and the following
on-chip peripherals: Analog-to-Digital converter
(ADC) with 8 multiplexed analog inputs, Op-Amp
module, synchronous SPI serial interface, asyn-
cronous serial interface (SCI), Watchdog timer, a
16-bit Timer featuring external Clock Input, Pulse
Generator capabilities, 2 Input Captures and 2
Output Compares, an 8-bit Timer featuring exter-
nal Clock Input, Pulse Generator Capabilities (2
channels), Autoreload and Input Capture.
The Op-Amp module adds on-chip analog fea-
tures to the MCU, that usually require using exter-
nal components.
