8-bit MCUs offer up to 16KB Flash option

Article By : Microchip Technology

ATtiny1617 MCUs enable operation up to 5.5V, increased system throughput, customised configuration and simplified process of capacitive touch systems.

Microchip Technology has launched its ATtiny1617 series of microcontrollers—three additional microchip varieties from its AVR 8-bit MCU portfolio. The addition features Core Independent Peripherals (CIPs) that help increase system throughput while lowering overall power consumption. The devices extend the memory offering up to a 16KB Flash option, while remaining pin and code compatible with ATtiny817 series devices. Furthermore, all members of the family are supported by Atmel START, an online tool for intuitive graphical configuration of embedded software projects.

The ATtiny1617 MCUs offer in-system self-programmable 16KB Flash memory, 256B EEPROM and 2KB RAM in 14-, 20- and 24-pin options. The devices contain key features of other tinyAVR MCUs including the Event System Controller that allows peripherals to communicate without using the Central Processing Unit (CPU) and enables designers to customise the configuration of the MCU for their specific application.

The on-chip Peripheral Touch Controller (PTC) simplifies the development of capacitive touch systems. Other integrated features include: a 20MHz internal oscillator, high-speed serial communication with USART, SPI, I2C, configurable custom logic blocks, a 10-bit Analog-to-Digital Converter (ADC) with internal voltage references, operating voltages ranging from 1.8V to 5.5V and picoPower technology for sleep currents as low as 100nA.
