Nu Horizons expands Atmel's TinyAVR range
Nu Horizons Electronics
ATtiny48 microcontroller
Nu Horizons Electronics has added the ATtiny48 and ATtiny88 to Atmel's TinyAVR family of microcontrollers.
The 32-pin devices are pin-compatible with Atmel's ATmega48 and 88 parts and offer feature-optimised alternatives for cost-constrained applications.
The new microcontrollers use most of the features of Atmel's Picopower technology to eliminate excess power consumption.
These include brown-out detection circuitry that can be turned off during sleep modes, a power-reduction register that powers-down individual peripherals and digital-input disable registers that remove leakage current on ADC input pins.
The ATtiny48 and 88 are suitable for a range of applications in consumer, communications and industrial electronics where the application code is moderate but many I/O pins are needed.
Low power capability also makes the new devices suitable for battery-powered or power-constrained systems.
Target applications include: white goods, remote access systems, HVAC, mobile phones, battery chargers, industrial control, health care, wireless equipment and peripherals.
The ATtiny48 features 4kBytes of in-system self-programmable Flash, while the ATtiny88 features 8kBytes.
Both parts include a 64-byte in-system programmable EEPROM, internal temperature sensor, 10-bit ADC and a byte-oriented I2C interface for 400kHz I2C communication.
