- M Series - Microcontroller applications
- main-stream market
- Low-power
- short pipeline (as low as 2 stages in M+, 3 stages in M0, M3, M4, 6 stages in M7)
- slower clock speed due to short pipelines (say, 100MHz)
- quick and deterministic interrupt responses with closely coupled execution control
- Built-in interrupt management controller NVIC (Nested Vectored Interrupt Controller)
- C-language friendly
- used in sensors, wireless communication chipsets, mixed signal ASICs/ASSPs, or as in subsystems to assist comples application processors/SoC products.
- R Series - High performance Real-time systems
- real time fast data-crunching for modern IoT applications.
- fairly high clock speed (500 MHz to 1 GHz)
- very responsive to hardware events
- cache memories
- tightly coupled memories for deterministic behavior for interrupt handling
- higher reliability features (ECC for memory systems, dual-core lock-step)
- used in hard drive controllers, wireless baseband controllers, modem, automotive and industrial controllers.
- A Series - High end Application processors
- support Android, Linux, Windows, iOS
- longer processor pipeline
- high clock frequency (>1 GHz)
- MMU to support virtual memory addressing
- optional Java support
- secure program excution environment (TrustZone)
- used in smart phones, tablets, TVs, green servers.
- not for real time rapid responses.
- SecurCore Series - for security-sensitive products with temp resistance features, such s SIM cards, banking/payment systems and some electronic ID cards.
