Why Choose Cortex-M3 from Luminary Micro?
Cortex-M3 is the MCU version of ARM’s v7-M instruction set architecture family of cores: • Optimized for single-cycle flash usage • Deterministic, fast interrupt processing: always 12 cycles, or just 6 cycles with tail-chaining • Three sleep modes with clock gating for low power • Single-cycle multiply instruction and hardware divide • Atomic operations • ARM Thumb2 mixed 16-/32-bit instruction set • 1.25 DMIPS/MHzbetter than ARM7 and ARM9 • Extra debug support including data watchpoints and flash patching Capabilities beyond ARM7 for the microcontroller market: • Requires the flash (code space) of ARM7 applications • 24 times faster on MCU control applications • No assembly code requiredever!
