STMicroelectronics STM32 F2 Microcontrollers

STMicroelectronics STM32 F2 Microcontrollers uses ST's advanced 90nm NVM process technology with the innovative adaptive real-time memory accelerator (ART Accelerator™) and multi-layer bus matrix. These Arm® Cortex™-M3 based microcontrollers offer an unprecedented trade-off in price and performance. The series is characterized by a high degree of integration combining up to 1Mbyte of Flash memory and up to 128Kbytes of SRAM with Ethernet MAC, USB 2.0 HS OTG, camera interface, hardware encryption support, and external memory interface. ST's acceleration technology enables these MCUs to achieve up to 150 DMIPS/398 CoreMark at 120MHz FCPU, which is equivalent to zero wait state execution, while keeping the dynamic current consumption at the outstandingly low level of 175µA/MHz.
