MICROCHIP ATTINY25-20SU 8 Bit Microcontroller, Low Power High Performance, ATtiny, 20 MHz, 2 KB, 128 Byte, 8 Pins, SOICThe ATTINY25 20SU is a 8 bit high performance low power Atmel AVR RISC based Microcontroller combines 2kB ISP flash memory, 128B EEPROM, 128B SRAM, 6 general purpose I O lines, 32 general purpose working registers, one 8 bit timer counter with compare modes, one 8 bit high speed timer counter, USI, internal and external Interrupts, 4 channel 10 bit A D converter, programmable watchdog timer with internal oscillator, three software selectable power
The ATTINY25-20SU is a 8-bit high-performance low-power Atmel AVR RISC-based Microcontroller combines 2kB ISP flash memory, 128B EEPROM, 128B SRAM, 6 general purpose I/O lines, 32 general purpose working registers, one 8-bit timer/counter with compare modes, one 8-bit high speed timer/counter, USI, internal and external Interrupts, 4-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, three software selectable power saving modes and debugWIRE for on-chip debugging. The device achieves a throughput of 20 MIPS at 20MHz and operates between 2.7 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
- Advanced RISC architecture - 120 powerful instructions, most single clock cycle execution
- Non-volatile program and data memories
- Peripheral features - On-chip analogue comparator
- debugWIRE on-chip debug system
- In-System Programmable via SPI port
- External and internal interrupt sources
- Low power idle, ADC noise reduction and power-down modes
- Enhanced power-on reset circuit
- Programmable brown-out detection circuit
- Internal calibrated oscillator

Best Blanket Ever!!
Color: 16- Dusty Pink, Size: Twin (60" X 80"), Color: 16- Dusty Pink, Size: Twin (60" X 80")
I am in LOVE with this blanket. I got the dusty Rose, the color is Spot On to the pics. It's perfect size, I bought the twin size. It's reversible, and is Super Soft. Plus, No Shedding. Well made, perfect blanket, it's thick yet but not overly making it perfect for year round. Definitely, worth the money. I sleep great with it. It's so pretty, I love it. Will but again in other colors as well.
