The ATTINY44A-PU, a microcontroller belonging to Atmel's AVR family, is a versatile and cost-effective integrated circuit (IC) component. Here's an overview of its key features:
1. CPU: The ATTINY44A-PU features a high-performance 8-bit AVR RISC CPU with a reduced instruction set architecture (RISC). It operates at a clock frequency of up to 20 MHz, providing efficient processing capabilities.
2. Flash Memory: It offers 4KB of in-system programmable Flash memory where user code and application-specific functions can be stored. This memory can be written or erased using an In-Circuit Serial Programming (ICSP) or by an external programmer.
3. EEPROM: In addition to Flash memory, the microcontroller integrates 256 bytes of Electrically Erasable Programmable Read-Only Memory (EEPROM). It enables storing critical data that needs to be retained during power loss or system reset.
4. SRAM: The ATTINY44A-PU incorporates 256 bytes of static random-access memory (SRAM). This volatile memory acts as a temporary storage area for data during program execution.
5. I/O Pins: It features a total of 12 general-purpose I/O pins that can be configured as inputs or outputs. These pins allow interfacing with other devices such as sensors, actuators, and communication modules
