STR751FR2T6

STR751 系列 32位 256 kB 闪存 16 kB RAM ARM7 微控制器 - LQFP-64

The STR750 family of 32-bit microcontrollers combines the industry-standard ARM7TDMI® 32-bit RISC core, featuring high performance, very low power, and very dense code, with a comprehensive set of peripherals and ST"s latest 0.18μ embedded Flash technology. The STR750 family comprises a range of devices integrating a common set of peripherals as well as USB, CAN and some key innovations like clock failure detection and an advanced motor control timer. It supports both 3.3V and 5V, and it is also available in an extended temperature range -40 to +105°C. This makes it a genuine general purpose microcontroller family, suitable for a wide range of applications.
