ST72321BJ9-AUTO规格书详情
Description
The ST72F321B-Auto Flash and ST72321B-Auto ROM devices are members of the ST7 microcontroller family designed for mid-range automotive applications. Different package options offer up to 48 I/O pins.
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. The ST7 family architecture offers both power and flexibility to software developers, enabling the design of highly efficient and compact application code.
Features
Memories
