ATTINY9 Programming Manual

●The ATTINY9-TSHR is a 8-bit high-performance low-power AVR RISC-based Microcontroller combines 1kB ISP flash memory, 32B SRAM, 4 general purpose I/O lines, 16 general purpose working registers, a 16-bit timer/counter with two PWM channels, internal and external interrupts, programmable watchdog timer with internal oscillator, an internal calibrated oscillator and 4 software selectable power saving modes. The device operates between 1.8 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 - 54 powerful instructions, most single clock cycle execution

● Non-volatile program and data memories

● Peripheral features - Programmable watchdog timer with separate on-chip oscillator

● In-System Programmable (at 5V, only)

● External and internal interrupt sources

● Low power idle, ADC noise reduction and power-down modes

● Enhanced power-on reset circuit

● Programmable supply voltage level monitor with interrupt and reset

● Internal calibrated oscillator

● Industrial and extended temperature ranges
