ST7262
1 INTRODUCTION
The ST7262, ST72P62 and ST72F62 devices are
members of the ST7 microcontroller family de-
signed for USB applications.
All devices are based on a common industry-
standard 8-bit core, featuring an enhanced instruc-
tion set.
The ST7262 devices are ROM versions.
The ST72P62 devices are Factory Advanced
Service Technique ROM (FASTROM) versions:
they are factory-programmed and are not repro-
grammable.
The ST72F62 versions feature dual-voltage
FLASH memory with FLASH Programming capa-
bility.
Under software control, all devices 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.
