2 GENERAL DESCRIPTION
2.1 INTRODUCTION
The ST72334J/N, ST72314J/N and ST72124J de-
vices aremembers ofthe ST7microcontroller fam-
ily. They can be grouped as follows:
– ST72334J/Ndevices are designedfor mid-range
applications with Data EEPROM, ADC, SPI and
SCI interface capabilities.
– ST72314J/N devices target the same range of
applications but without Data EEPROM.
– ST72124J devices are for applications that do
not need Data EEPROM and the ADC peripher-
al.
All devices are based on a common industry-
standard 8-bitcore, featuringan enhancedinstruc-
tion set.
The
ST72C124J
FLASH memory with byte-by-byte In-Situ Pro-
gramming (ISP) capability.
Under software control, all devices can be placed
in WAIT, SLOW, ACTIVE-HALT or HALT mode,
reducing power consumption when theapplication
is in idle or standby state.
The enhanced instruction set and addressing
modes of the ST7 offer both powerand flexibility to
software developers, enabling the design of highly
efficient and compact application code. In addition
to standard 8-bit data management, allST7 micro-
controllers feature true bit manipulation, 8x8 un-
signed multiplication
and indirect addressing
modes.
