Atmel Corp. has rolled out its next-generation 8bit megaAVR MCUs that flaunt additional analogue functionality and features for the latest low-power consumer, industrial, white goods, automotive and Internet of Things (IoT) applications. According to the company, the simple, low-power MCUs feature a selection of development tools such as a free Atmel Studio IDE, extensive set of peripherals such as ADC, analogue comparator, SPI, I2C and USART, and single-cycle instructions running 1MIPS per MHz.

Made for engineers of all levels from the professional and established designers to the hobbyist, do-it-yourselfer (DIY) and maker communities, the MCUs, supporting flash memory from 4-16KB, are geared for applications in various markets and deliver all the benefits of previous generations including a simple, easy-to-use interface for a seamless upgrade and binary compatibility with existing 8bit megaAVR MCUs, indicated the company.

The devices are geared for high-level languages with minimal code space and boast real-time performance with single cycle I/O access. The 8bit megaAVR MCUs has a unique ID for every device enabling a more secure device for IoT applications and wireless networks, and touts improved accuracy of internal oscillators for UART serial communications and internal voltage reference for better analogue-to-digital conversion results, added Atmel.

To accelerate a developer's design, Atmel offers an ultra-low cost Xplained Mini development platform for $8.88 and fully compatible with 8bit megaAVR MCUs. The boards can easily be connected to any Arduino board making it ideal for a variety of projects and prototypes using an Arduino board.

The megaAVR 8bit MCUs are fully supported by Atmel's development ecosystem including Atmel Studio 6.2, the IDE for developing and debugging Atmel | SMART Cortex-M and Atmel AVR MCU-based applications. Atmel Studio 6.2 gives designers a seamless and easy-to-use environment to write, build, simulate, program and debug their applications to write, build, simulate, program and debug your applications written in C/C++ or assembly code using the integrated GCC compiler and AVR assembler.

The Atmel mega168PB, mega88PB and mega48PB are available in 32-pin QFN and QFP packages with additional devices available later this year. All devices are sampling. Production quantities for the mega168PB devices are available while the mega88PB and ATmega48PB devices are available in February 2015.
