A year after its debut, we’re excited to share that we’ve expanded our award-winning SAM G series of ARM Cortex-M4-based MCUs with the new SAM G54 and SAM G55.
Targeting the rapidly emerging Internet of Things (IoT) market for battery-operated devices including wearables, such as fitness bands and smart watches, sensor hub management, healthcare, gateways, bridges, audio devices and much more, the new pair of MCUs deliver the right feature mix including higher performance, ultra-low power, smaller form factors and more SRAM. These two series also pack all the features of the current SAM G family like an Atmel | SMART ARM Cortex-M4 MCU + FPU (floating point unit), integrated sensor fusion algorithms, down to 2.84 x 2.84mm package, high-performance frequency of up to 120MHz, ultra-low power down to 102µA/MHz in active mode, and down to 5µs wake-up.
Among the other key features for the new SAM G series:
- High-performance throughput and efficiency with a Cortex M4-based MCU and FPU
- Up to 512KB of Flash and up to 160KB of SRAM
- SRAM power banking
- Down to 2.84 X 2.84mm 49-ball WLCSP with 0.4mm pitch
- Flexible serial peripherals and ultra-low power ADC
- USB host and device
- Peripheral Event System and SleepWalking
- Atmel ultra-low power picoPower® technology
- 64-pin QFP and QFN package options.
In order to maintain energy efficiency, many smart, connected devices use a sensor hub to aggregate and manage the sensors in the device, converting the information into usable data to improve power efficiency and performance. The new SAM G55 series gives designers the option to determine how much SRAM they will require to retain in sleep mode in order to achieve lower and better power efficiency for their designs by utilizing SRAM power banking.
“Designers are looking for simple-to-use solutions with an edge to help bring their differentiated products faster to market for both wearables and sensor hub management,” said Vince Murdica, Atmel Senior Director of Sensor Centric Systems. “Atmel’s new SAM G series delivers differentiation for these markets by offering ultra-low power, higher performance, more memory and smaller form factor, along with connectivity options on a single chip to fuel the innovation. Atmel’s expanded SAM G series builds on our portfolio of touch, security, connectivity and software solutions for this rapidly growing market.”
To accelerate the design, a SAM G55 Xplained Pro evaluation kit is currently available for the SAM G55 series. The ATSAMG55-XPRO evaluation board includes an embedded debugger, Atmel Studio integrated development platform and the Atmel Software Framework. The kit is also fully supported by third party partners IAR and Keil.
