The ATmega8515 is an 8-bit microcontroller from Microchip Technology (formerly Atmel). It's a low-power CMOS microcontroller based on the AVR enhanced RISC architecture, offering a good balance of features and memory capacity for various embedded system projects.

Here's a breakdown of its key features:

  • 8-bit CPU: Processes 8 bits of data at a time.
  • 8 KB Flash Memory: Provides ample space to store your program code compared to some earlier ATmega models like the ATmega8A (with 8KB) or ATmega16 (16KB).
  • 512 Bytes Internal RAM: Offers temporary data storage during program execution.
  • Up to 64 KB External SRAM: While the ATmega8515 itself doesn't have a large internal SRAM, it can be interfaced with external SRAM for additional data storage needs.
  • 512 Bytes EEPROM: Non-volatile memory retains data even when powered off, useful for storing configuration settings.
  • 23 Programmable I/O Lines: These allow communication with external devices like sensors and actuators.
  • Timers/Counters: Useful for timing and counting events (typically 2 or 3 timers/counters).
  • Serial Communication Interface: USART for serial communication with other devices.
  • 2-cycle On-chip Multiplier: This hardware multiplier can improve performance for certain calculations compared to software-based multiplication.
  • Low Power Consumption: Offers various power-saving modes to extend battery life in portable applications.

Applications:

The ATmega8515's features make it suitable for various embedded system projects that require a balance of performance and power efficiency. Here are some examples:

  • Data acquisition systems: Can be used to collect and store sensor data, potentially using the USART for serial communication with a host computer.
  • Motor control: Timers and I/O lines can be used to control motors.
  • Simple control systems: The extra memory and features compared to some earlier ATmega models enable handling more intricate tasks.
  • Portable devices: The low-power consumption is beneficial for battery-powered applications.
