Atmel’s new devices are 20-pin tiny-AVR microcontrollers with high-speed timers.
All three devices are pin-compatible, differing only in the size Flash, EEPROM and SRAM memories.
- The ATtiny261 has 2 Kbytes of self-programmable Flash memory;
- The ATtiny461 has 4 Kbytes of self-programmable Flash memory;
- The ATtiny861 has 8 Kbytes of self-programmable Flash memory.
All devices deliver 20 MIPS throughput when running at maximum 20 Mhz frequency.
The internal 8 MHz RC oscillator and the on-chip PLL can run the 10-bit timer/counter up to 64 Mhz speed. The high-speed timer/counter with three independent PWM generators is 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 outputs.
ATtiny261, ATtiny461 and ATtiny861 are available in 20-pin SOIC and PDIP and 32-pad QFN packages.
