Energy Micro introduced their 32-bit EFM32 Gecko microcontroller family. Based on the ARM Cortex(TM)-M3 microcontroller architecture, the EFM32G has been proven to extend battery life by a factor of four, consuming a quarter of the energy required by existing 8, 16 ,or 32-bit microcontrollers. The first products are being offered by Energy Micro in QFN64 and BGA112 profiles and are currently sampling with lead customers. Pricing for the initial 32-pin devices starts at $1.55 in 100k quantities.
Energy Micro EFM32G Gecko Microcontroller Features
- 4×40 segment LCD controller running at less than 900nA
- 8-channel 12-bit 1M samples/sec ADC running at less than 200µA
- Brown-out detector running at less than 100nA
- 32kHz real time counter running at 50nA
- UART capable of 9600bps at 100nA
Proven to consume less than 180µA per MHz while executing real life code from Flash, the EFM32G achieves the lowest active mode current consumption of any microcontroller. Its standby current consumption is also the lowest, at typically 900nA while running real time clock, power-on reset, brown-out detector and full RAM and CPU retention and less than 20nA in its deepest sleep mode. In addition, the microcontroller’s start-up time of less than 2µs is the industry’s fastest.
22 different EFM32G microcontroller products will become available over the next few months, in a variety of packages including QFN32, QFN64, QFP100 and BGA112. The EFM32G operates from a single supply rail of between 1.8 and 3.8V. The operating temperature range is -40 deg C to +85 deg C. The microcontrollers provide up to 128KB Flash memory and up to 16KB of RAM.
