The STR750F is a new series of super-integrated, single-chip 32-bit ARM7-based MCUs from STMicroelectronics. Delivering performance without compromise, the STR750F series combines high performance and low power consumption with ample memory and a full peripheral set in a single device. With a wide range of available configurations, the STR750F series is ideal for virtually any application. Packed with peripherals, the STR750F series offers a host of innovative features for advanced control, security and communication. Based on an ARM7TDMI core, the STR750F series offers high performance with 54MIPS at 60MHz and low power consumption down to 10µA in standby mode. To increase versatility, the STR750F can be used with either a 3.3V or a 5V power supply.
