  • ARMcore 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 anembedded 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.
    For more information, please refer to ST MCU site http://www.st.com/mcu
    Figure 1 shows the general block diagram of the device family.
