Product Summary
The LM3S2276-IQR50-A0 is an ARM Microcontroller. It brings high-performance 32-bit computing to cost-sensitive embedded microcontroller applications. These pioneering parts deliver customers 32-bit performance at a cost equivalent to legacy 8- and 16-bit devices, all in a package with a small footprint.
Parametrics
LM3S2276-IQR50-A0 absolute maximum ratings: (1)I/O supply voltage (VDD):0V to 4V; (2)Core supply voltage (VDD25):0V to 3V; (3)Analog supply voltage (VDDA):0V to 4V; (4)Battery supply voltage (VBAT):0V to 4V; (5)Input voltage:-0.3V to 5.5V; (6)Input voltage for a GPIO configured as an analog input:-0.3V to VDD+0.3V; (7)Maximum current per output pins:25mA; (8)Maximum input voltage on a non-power pin when the microcontroller is unpowered:300mA.
Features
LM3S2276-IQR50-A0 features: (1)32-bit ARM Cortex-M3 v7M architecture optimized for small-footprint embedded applications; (2)System timer (SysTick), providing a simple, 24-bit clear-on-write, decrementing, wrap-on-zero counter with a flexible control mechanism; (3)Thumb-compatible Thumb-2-only instruction set processor core for high code density; (4)50-MHz operation; (5)Hardware-division and single-cycle-multiplication; (6)30 interrupts with eight priority levels; (7)Memory protection unit (MPU), providing a privileged mode for protected operating system functionality; (8)Unaligned data access, enabling data to be efficiently packed into memory.
