STR712FR2T6 Description
The STR71x series is a family of ARM-powered 32-bit microcontrollers with embeddedFlash and RAM. It combines the high performance ARM7TDMI CPU with an extensiverange of peripheral functions and enhanced I/O capabilities. STR71xF devices have on-chiphigh-speed single voltage FLASH memory and high-speed RAM. STR710R devices havehigh-speed RAM but no internal Flash. The STR71x family has an embedded ARM core andis therefore compatible with all ARM tools and software.
