Microchip, the popular manufacturer of microcontrollers and semi-conductors, has recently unveiled the new generation of 8-bit tiny AVR MCUs. The four new products in the lineup carry 14-24 pins and 4Kb-8Kb of Flash. These are the first tinyAVR microcontrollers equipped with Core Independent Peripherals.
The newly-rolled-out products are supported by an innovative online tool named as START, meant for intuitive and graphical configuration of embedded software projects. This tool can be availed free of cost and provides an optimized framework thereby letting the users make use of differentiating features to their application.
Moving on to the features of the ATtiny817/816/814/417 devices, these are equipped with a CIP called Peripheral Touch Controller (PTC), custom programmable logic blocks, Event System for peripheral co-operation, self programming for firmware upgrades, and custom programmable logic blocks. CIPs enable the peripherals to function independently of the core whereas the Event System allows the peripheral communication without CPU.
Adding to the list, there are elements like non-volatile data storage, high-speed serial communication with USART, and 20MHz internal oscillator. Other specifications consist of 10-bit ADC with internal voltage references, operating voltages in the range of 1.8V to 5.5V. Further these devices also carry sleep currents at less than 100 nA in power down mode with SRAM (Static RAM) retention.
Commenting on the launch, Mr. Steve Drehobl, Vice President of Microchip’s MCU8 division stated, “As the number one provider of 8-bit MCUs with our broad portfolio of PIC, AVR and 8051 MCU Crores, we are committed to providing our customers with more products that can help differentiate their designs.”
“By adding innovative capabilities like Core Independent Peripherals, interconnected analog and intuitive graphic design support that have been available on PIC MCUs for some time, we are continuing to provide our AVR MCU customers with the right tools to innovate and get to market fast” he added.
