Oslo, Norway - Energy Micro has announced details of the EFM32 Giant Gecko microcontroller (MCU) product family, designed for sensitive applications with high memory requirements. The 32-bit Giant Gecko (GG) will provide Flash configurations up to 1024KB with the option of embedded USB connectivity. The new line is due to start sampling in Q1 2011.
Forty-eight EFM32GG MCUs will offer a choice of 64, 128, 256, 512 and 1024 KB Flash memory blocks and a RAM of 32KB or 128KB. The new MCUs' pin and software compatibility with the existing Gecko product family means designers can develop products using the existing Gecko microcontroller and migrate to Giant Gecko when the higher memory parts enter production. Package options will include QFN64, QFP100 and BGA112.
Built around the energy-efficient ARM Cortex-M3 processor architecture, the Giant Gecko, Gecko and Tiny Gecko microcontrollers demonstrate an energy usage a quarter of that of alternative 8-, 16- or 32-bit MCUs. With a wake-up time of just 2µs and current consumption of 180µA per MHz executing code from Flash, 900nA in deep-sleep mode and 20nA in shut-off mode, the MCUs are proven capable of extending typical battery life by 300 percent.
The Giant Gecko's embedded USB connectivity option will be USB2.0 compliant at full speed (12Mbit/s), integrating 2KB endpoint buffers and handling up to 10 endpoints. It will provide support for USB host and on-the-go configurations as well as bootloader over USB. Additional extended communication options offered by Giant Gecko will include dual I2C and up to five USART/UART serial interfaces.
Giant Gecko will feature the same selection of energy-saving peripherals as the companion Gecko and Tiny Gecko products. These include an 8-channel, 12-bit ADC using 200µA at full resolution and 1Msamples/sec conversion rate, a 4x40 segment LCD controller using 900nA, and a special Low Energy UART consuming just 100nA at 9600baud. For wireless encryption/decryption duties, an 128/256-bit AES accelerator block is also provided.
The EFM32 Giant Gecko from Energy Micro will begin sampling in Q1 2011. Pricing will start at $2.5 USD each in 100k quantities. Detailed datasheets on the Giant Gecko will be released November 1st 2010. Further information is available at www.energymicro.com.
