[Luminary Micro, Inc.]
Architectural Overview
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 LM3S612 controller in the Stellaris family offers the advantages of ARM’s widely available development tools, System-on-Chip (SoC) infrastructure IP applications, and a large user community. Additionally, the controller uses ARM’s Thumb®-compatible Thumb-2 instruction set to reduce memory requirements and, thereby, cost.
Luminary Micro offers a complete solution to get to market quickly, with a customer development board, white papers and application notes, and a strong support, sales, and distributor network.
Product Features
The LM3S612 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) provides 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
– 25 interrupts with eight priority levels
– Memory protection unit (MPU) provides a privileged mode for protected operating system functionality
– Unaligned data access, enabling data to be efficiently packed into memory
– Atomic bit manipulation (bit-banding) delivers maximum memory utilization and streamlined peripheral control
■ Internal Memory
– 32-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
– 8-KB single-cycle SRAM
■ General-Purpose Timers
– Three timers, each of which can be configured: as a single 32-bit timer, as two 16-bit timers, or to initiate an ADC event
– 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
