1.1
Overview
ARM core with embedded Flash & RAM
STR73xF family combines the high performance ARM7TDMI CPU with an extensive range
of peripheral functions and enhanced I/O capabilities. All devices have on-chip high-speed
single voltage FLASH memory and high-speed RAM. The STR73xF 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.

Package Choice: Reduced Pin-Count TQFP100 or Feature-Rich 144-pin TQFP or
LFBGA
The STR73xF family is available in 3 packages. The TQFP144 and LFBGA144 versions
have the full set of all features. The 100-pin version has fewer timers, I/Os and ADC
channels. Refer to the Device Summary on Page 1 for a comparison of the I/Os available on
each package.
The family includes versions with and without CAN.
