The STR7 microcontrollers are a new range of high-performance 32-bit microcontrollers made by STMicroelectronics. Built on leading ARM architecture, the STR7 family comprises highly integrated microcontrollers with embedded Flash, and flexible embedded-processors with cache, MMU and memory interfaces.
* STR710F 32-bit Flash MCU: The STR710F series with embedded Flash is ideal for embedded applications requiring a compact yet powerful MCU, or versatile scalable solutions such as user interfaces, factory automation systems and point-of-sale applications.
The STR710F features industry standard ARM7TDMI RISC 32-bit CPU; 128 K/256 K embedded Flash with 16 k data Flash; 16/64 K high-speed SRAM; versatile package options, with a small low pin count TQFP64 package and a TQFP144 package with external memory interface; up to 10 communication interfaces including CAN, USB, HDLC and smartcard interface; and four low-power modes.
* STR720 32bit embedded processor: The STR720F series with cache, MMU and SDRAM interface is ideal for embedded applications requiring high computing power, flexible system memory and an advanced operating system.
The STR720F features: an industry standard ARM720T RISC 32-bit CPU, 8 KB cache and memory management unit, external memory interface for Flash and SRAM, SDRAM interface with 128 MB address space, six communication peripherals including CAN and USB; and four low-power modes.
Development tools, support
Through its partnership with ARM, ST is able to provide a low-cost ARM RealView Developer Kit specifically for ST devices, based on the popular ARM RealView Developer Suite software and hardware solution. Further, numerous compilers, emulation systems and operating systems from third-party tool vendors support the STR7 products.
