Microchip launches 8bit AVR MCUs with CIPs

A new generation of 8bit tinyAVR microcontrollers has been introduced by Microchip. The four devices range from 14 to 24 pins and are claimed to be the first tinyAVR MCUs to feature core independent peripherals. The devices will be supported by START, an online tool for the graphical configuration of embedded software projects.

The ATtiny817/816/814/417 devices feature small, low pin-count and feature-rich peripherals with 4 or 8KB of flash memory. Other integrated features include: a core-independent peripheral touch controller; event system for peripheral co-operation; custom programmable logic blocks; self-programming for firmware upgrades; non-volatile data storage; 20MHz internal oscillator; high speed serial communication with USART; operating voltages ranging from 1.8 to 5.5V; 10bit A/D converters with internal voltage references; and sleep currents at less than 100nA in power-down mode with SRAM retention.

According to the company, CIPs allow the peripherals to operate independently of the core and include serial communication and analogue peripherals. Together with the event system, which allows peripherals to communicate without using the CPU, applications can be optimised at a system level. This is said to lower power consumption and increases throughput and system reliability.
