Supported ARM devices from Energy Micro |
The 32-bit EFM32 microcontroller family from Energy Micro have ultra low energy consumption, a modern and powerful ARM® Cortex™-M3 CPU, and a feature set especially suited for low power and battery operated applications.
The EFM®32 Gecko microcontroller family gives 4 times longer battery life than any other 8, 16, or 32-bit microcontroller. All EFM32 MCUs have ultra low power consumption of 180 µA/MHz while running applications from Flash memory and a Shutoff mode with only 20 nA current consumption. Without CPU intervention the low power peripherals that can react and respond to other peripherals, external, or internal triggers. This results in fast execution, low latency, and the longest operation time for any battery operated applications. |
| IAR Embedded Workbench® for ARM provides device support on these levels: |
|
|
| | |
| Instruction set support in compiler, assembler, linker and debuggers. |
|
|
|
|
|
|
| |
| Peripheral register names in C/assembler source and debugger as well as device setup configuration files. |
|
|
|
|
|
|
| |
| For on-chip flash or off-chip EVB flash. |
|
|
|
|
|
|
| |
| Varies from simple to fairly complex applications. |
