LM3S2110 Datasheet, PDF (21/485 Pages) List of Unclassifed Manufacturers – Microcontroller

LM3S2110 Microcontroller
– Integrated Nested Vectored Interrupt Controller (NVIC) providing deterministic interrupt
handling
– 26 interrupts with eight priority levels
– Memory protection unit (MPU), providing a privileged mode for protected operating system
functionality
– Unaligned data access, enabling data to be efficiently packed into memory
– Atomic bit manipulation (bit-banding), delivering maximum memory utilization and streamlined
peripheral control
■ Internal Memory
– 64 KB single-cycle flash
• User-managed flash block protection on a 2-KB block basis
• User-managed flash data programming
• User-defined and managed flash-protection block
– 16 KB single-cycle SRAM
■ General-Purpose Timers
– Three General-Purpose Timer Modules (GPTM), each of which provides two 16-bit timers.
Each GPTM can be configured to operate independently:
• As a single 32-bit timer
• As one 32-bit Real-Time Clock (RTC) to event capture
• For Pulse Width Modulation (PWM)
– 32-bit Timer modes
• Programmable one-shot timer
• Programmable periodic timer
• Real-Time Clock when using an external 32.768-KHz clock as the input
• User-enabled stalling in periodic and one-shot mode when the controller asserts the CPU
Halt flag during debug
– 16-bit Timer modes
• General-purpose timer function with an 8-bit prescaler
• Programmable one-shot timer
• Programmable periodic timer
• User-enabled stalling when the controller asserts CPU Halt flag during debug
