Description
Introduction
The ST7232AK1-Auto, ST7232AK2-Auto, ST7232AJ1-Auto, and ST7232AJ2-Auto devices
are members of the ST7 microcontroller family designed for the 5V operating range.
The 32 and 44-pin devices are designed for mid-range applications
All devices are based on a common industry-standard 8-bit core, featuring an enhanced
instruction set and are available with Flash or ROM program memory.
Under software control, all devices can be placed in wait, slow, active halt or halt mode,
reducing power consumption when the application is in idle or stand-by 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 microcontrollers
feature true bit manipulation, 8 x 8 unsigned multiplication and indirect addressing modes.
