| ATtiny841 pinout |
The ATtiny841 [
datasheet.pdf] is the latest Tiny and it kicks butt. While the '841 shares pinout and memory sizes with the ATtiny84, the new chip boasts some truly incredible features:
- One 8-bit and Two 16-bit Timer/Counters with Two PWM Channels, EachProgrammable Ultra Low Power Watchdog Timer
- 10-bit Analog to Digital Converter
- 12 External and 5 Internal, Single-ended Input Channels
- 46 Differential ADC Channel Pairs with Programmable Gain (1x / 20x / 100x)
- Two On-chip Analog Comparators
- Two Full Duplex USARTs with Start Frame Detection
- Master/Slave SPI Serial Interface
- Slave I2C Serial Interface
The 14-pin AVR comes in surface mount packages, only. However, I'm selling a breakout board with AVRISP header, reset circuit, and built-in 16MHz crystal and caps.
Buy it here for $10.
