Description
ARM
®
core with embedded Flash and RAM
The STR71x series is a family of ARM-powered 32-bit microcontrollers with embedded
Flash and RAM. It combines the high performance ARM7TDMI CPU with an extensive
range of peripheral functions and enhanced I/O capabilities. STR71xF devices have on-chip
high-speed single voltage FLASH memory and high-speed RAM. STR710R devices have
high-speed RAM but no internal Flash. The STR71x family has an embedded ARM core and
is therefore compatible with all ARM tools and software.
Extensive tools support
STMicroelectronics’ 32-bit, ARM core-based microcontrollers are supported by a complete
range of high-end and low-cost development tools to meet the needs of application
developers. This extensive line of hardware/software tools includes starter kits and complete
development packages all tailored for ST’s ARM core-based MCUs. The range of
development packages includes third-party solutions that come complete with a graphical
development environment and an in-circuit emulator/programmer featuring a JTAG
application interface. These support a range of embedded operating systems (OS), while
several royalty-free OSs are also available.
