Detailed description

The circuit is made using picoPower technology – identical functionality with lower power consumption. An excellent solution for battery-powered devices.

Selected features:
* Available program and data memory:
- 64 kB of built-in Flash memory programmable within the chip;
- 2 kB EEPROM;
- 4 kB RAM;
* 32 input/output pins;
* Peripherals:
- Timers: two 8-bit timers and one 16-bit timer;
- 8-channel, 10-bit analog-to-digital converter;
- Real-time clock (RTC);
- 6-channel PWM mode;
- Analog comparator;
- Two fully duplex USART modules;
- Programmable Watchdog timer with an integrated internal oscillator;
- Master/Slave SPI serial interface;
- TWI serial interface – compatible with I²C™;
* Supply voltage: 2.7÷5.5 V;
* Operating temperature: -40÷85°C;
* For picoPower devices: Power Save mode – current consumption is around 600nA (with RTC enabled).
