[Luminary Micro, Inc.]
The Luminary Micro Stellaris® family of microcontrollers—the first ARM® Cortex™-M3 based controllers—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.
The Stellaris® family offers efficient performance and extensive integration, favorably positioning the device into cost-conscious applications requiring significant control-processing and connectivity capabilities.
The Stellaris® LM3S1000 series extends the Stellaris® family with larger on-chip memories, enhanced power management, and expanded I/O and control capabilities.
The Stellaris® LM3S2000 series, designed for Controller Area Network (CAN) applications, extends the Stellaris family with Bosch CAN networking technology, the golden standard in short-haul industrial networks.
Features
The LM3S2965 microcontroller includes the following product features:
• 32-Bit RISC Performance
– 32-bit ARM® Cortex™-M3 v7M architecture optimized for small-footprint embedded applications
– System timer (SysTick), providing a simple, 24-bit clear-on-write, decrementing, wrap-on-zero counter with a flexible control mechanism
– Thumb®-compatible Thumb-2-only instruction set processor core for high code density
– 50-MHz operation
– Hardware-division and single-cycle-multiplication
– Integrated Nested Vectored Interrupt Controller (NVIC) providing deterministic interrupt handling
– 42 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
– 256 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
– 64 KB single-cycle SRAM
• General-Purpose Timers
– Four 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)
• To trigger analog-to-digital conversions
– 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
• ADC event trigger
– 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
• ADC event trigger
– 16-bit Input Capture modes
• Input edge count capture
• Input edge time capture
– 16-bit PWM mode
• Simple PWM mode with software-programmable output inversion of the PWM signal(Continue ...)
