Atmel Announces Three Low-Power tinyAVR Microcontrollers With High-Speed Timers
San Jose, California, November 1 (ots/PRNewswire) -
Atmel(R) Corporation (Nasdaq: ATML) announced today three new 20-pin tinyAVR(R) Flash microcontroller devices with high-speed timers targeting battery chargers, sensor end-points and motor control applications.
The devices are pin-compatible, differing only in the size of their Flash, EEPROM and SRAM memories. The ATtiny261 has 2 Kbytes of self-programmable Flash memory, whereas the ATtiny461 and ATtiny861 have 4 Kbytes and 8 Kbytes, respectively. All devices deliver 20 MIPS throughput when running at 20 MHz.
"The ATtiny26 has been very successful and offered an unrivalled combination of processing power, analog performance and high-speed timers. We have updated this device with the latest AVR(R) features and increased processing speed while decreasing power consumption. The new ATtiny261 operates down to 1.8 volts. It also has enhanced interface options and a unique on-chip temperature sensor," said Jukka Eskelinen, Marketing Director for tinyAVR products. "The ATtiny461 and ATtiny861 offer a migration path to customers who run out of code space with the ATtiny261," he added.
The internal 8 MHz RC oscillator and the on-chip PLL run the 10-bit timer/counter at up to 64 MHz. The high-speed timer/counter with three independent PWM generators and programmable dead times make the devices ideal for battery chargers, battery monitoring, power monitoring and motor-control applications.
All devices have internal EEPROM, pull-up resistors, an internal 8 MHz precision oscillator and 12 general I/O pins for application use. Alternatively, the I/O pins work as ADC inputs or PWM (Pulse Width Modulation) outputs.
Commonly used microcontroller peripherals are all integrated. The ATtiny261/461/861 devices include a Universal Serial Interface (USI), which can be easily configured to work as an SPI, UART or TWI. Advanced analog capabilities, such as built-in temperature measurement, a fast analog comparator and a programmable analog gain amplifier, allow highly-integrated designs with a small price tag. A total of eleven 10-bit A/D converter input channels allow a wide selection of peripherals to be connected in sensor and control applications, and the internal temperature sensor allows reliable system parameter calibration.
The ATtiny261/461/861 excels in battery-powered equipment due to inherently low power consumption and individually-selectable low-power sleep modes. A balance between system performance and power consumption is achieved by directly controlling the system clock frequency. Additional power saving is achieved by selectively turning off timers, the serial interface, and/or ADCs when not in use. As a result, the power consumption of the device in 1.8V active mode at 1 MHz is less than 400 uA and in power-down mode just a few uA.
Price and Availability
Complete evaluation and debug tools are available for the tinyAVR microcontrollers. The STK(R)500 and STK505 starter kits are available at US$79 each and offer all the necessary hardware to evaluate programs and test the capabilities of the ATtiny261, ATtiny461 and ATtiny861.
Samples of ATtiny261, ATtiny461 and ATtiny861 are available in 20-pin SOIC and PDIP and 32-pad QFN packages. All three devices are in volume production. Volume prices for 10k units are US$0.80, US$0.90 and US$1.15, respectively.
