32-bit RISC Processor To Deliver High Performance In Low-Cost Microcontroller Applications
- Powerful debug and non-intrusive real-time trace - Comprehensive debug and trace features dramatically improve developer productivity. It is extremely efficient to develop embedded software with proper debug.
- Memory Protection Unit (MPU) - Software reliability improves when each module is allowed access only to specific areas of memory required for it to operate. This protection prevents unexpected access that may overwrite critical data.
- Integrated nested vectored interrupt controller (NVIC) - There is no need for a standalone external interrupt controller. Interrupt handling is taken care of by the NVIC removing the complexity of managing interrupts manually via the processor.
- Thumb-2 code density - On average, the mix between 16bit and 32bit instructions yields a better code density when compared to 8bit and 16bit architectures. This has significant advantages in terms of reduced memory requirements and maximizing the usage of precious on-chip Flash memory.
Small, Low Power, Energy Efficient 32-bit Microcontroller Processor
- Exceptional code density - on average, the mix between 16-bit and 32-bit instructions yields a better code density when compared to 8-bit and 16-bit architectures. This has significant advantages in terms of reduced memory requirements and maximizing the usage of precious on-chip Flash memory.
- Binary upward compatible with all other Cortex-M processors - the Cortex-M0 has mainly 16-bit Thumb-2 instructions and few 32-bit ones. These instructions are also present on all the other Cortex-M processors. Hence all code written for the Cortex-M0 will run as is on the other processors.
- Built-in low-power features - sleep, deep sleep and state retention are three low power modes available to the user
- Optional Debug Access Port and Serial Wire Debug - for devices where every pin counts the serial wire debug port uses only two pins
Deeply embedded processor for deterministic real-time applications
- Fast with high performance - the processor s 8-stage, dual-issue pipeline combined with instruction pre-fetch and branch prediction achieve fast instruction execution.
- Highly deterministic - advanced features such as Tightly-Coupled Memory (TCM), Vectored Interrupt Controller (VIC) port, and Low Latency Interrupt Mode (LLIM) make the Cortex-R4 highly deterministic with accelerated interrupt entry.
- Reliable - error handling built into the core; Integrated Memory Protection Unit (MPU), Error-correcting code (ECC) memory, and dual-core lock-step configuration ensure the Cortex-R4 processor’s reliability to handle errors.
- Energy efficient and cost effective - supports a highly flexible and efficient two-cycle local memory interface, enabling SoC designers to minimize system cost and energy consumption
Smallest, Lowest Power ARM Multicore Applications Processor
- Feature set of Cortex-A9 for half the size and power - Fully feature compatible with Cortex-A9 processor, provides 70-80% of Cortex-A9 performance and significantly higher efficiency.
- Most scalable and configurable Armv7-A processor - The Cortex-A5 processor is extremely configurable and scalable to meet performance, power and area requirements for cost sensitive, low power applications.
- Available in single core and multi core configurations - The Cortex-A5 processor is available in two variants: as a single core Cortex-A5 UP processor and as Cortex-A5 MP where it can scale up to four processor cores in a cluster.
