A new catalogue marks a quarter century of service to industry and further education.
It is available ex-stock from Rapid in a 14-pin surface mount plastic package.
ATtiny44 microcontrollers are ideal for battery-powered equipment thanks to their low power consumption, which is enhanced by three low power sleep modes.
On-chip features include internal EEPROM, pull-up resistors and an 8MHz high- precision calibrated RC oscillator, leaving 12 general I/O pins available for application use.
The I/O pins can work as ADC inputs or PWM outputs, depending on the application.
Interfacing is made easy by using a universal serial interface that can be configured to work as an SPI, UART or TWI.
For sensor applications, an on-chip temperature sensor accurately monitors the MCU temperature, aiding reliable system parameter calibration.
ATtiny44 microcontrollers include 8 and 16bit timers, which can control two 8bit and two 16bit PWM outputs, respectively.
Twelve 10bit, differential A/D convertor input channels with programmable gain and a fast analogue comparator allow a wide selection of peripherals to be connected when used in sensor and control applications.
The MCUs are supported by the professional AVR Studio debug environment, available free of charge from the Atmel website.
The STK500 Starter Kit, Rapid order code 73-4302 (GBP 67.50), offers all the necessary hardware to evaluate programs and test the capabilities of the ATtiny44.
Prices for the ATtiny44 microcontroller start at GBP 1.12 for 100-plus quantities from Rapid Electronics. Request a free brochure from Rapid Electronics ...
