Earlier this week, Atmel unveiled its SAM G lineup, an ARM Cortex-M4-based family of MCUs that integrate high performance and ultra-low power in a small form factor. The SAM G series is ideal for a wide range of sensor hub and battery-operated consumer applications, including smartphones, tablets and Ultrabooks as well as wearables, healthcare, gateways, bridges and audio devices.
Atmel’s SAM G launch was covered by a number of journalists and publications, including Paul Buckley of the EE Times (Europe).
“[In the age of] the Internet of Things (IoT), there is demand for MCUs with ultra-small form factors, rich features, high performance and lower power,” writes Buckley. “Atmel’s new SAM G51 and SAM G53 series meet all these requirements with 3×3 mm packaging, high-performance frequency at 48 MHz, ultra-low power consumption down to 100 µA/MHz in active mode, 7 µA in sleep with SRAM retention and down to 3 µs wake-up time.”
As Buckley notes, the new MCUs also feature a floating point unit (FPU) option for applications requiring additional computational power and precise calculations such as digital smart watches, wearables and mobile sensor hubs.
Additional key specs include:
- High-performance throughput and efficiency with a Cortex M4-based MCU and FPU
- Up to 512KB of Flash and 96KB of SRAM 3x3mm WLCSP, 49 balls with 0.4mm pitch
- Flexible serial peripherals and ultra-low power ADC
- Peripheral Event System and SleepWalking
- Atmel ultra-low power picoPower technology
