Detailed description
ATMEGA88PA-AU Microcontroller
The ATMEGA88PA-AU microcontroller is a high-performance yet energy-efficient 8-bit unit from the AVR® family, based on an advanced RISC architecture. With the ability to execute complex instructions in a single clock cycle, the device achieves a throughput close to 1 MIPS per MHz, enabling optimization of power consumption relative to data processing speed. This component provides a reliable foundation for electronic projects where miniaturization and precise resource management in embedded systems are essential.
Key Features and Specifications of the ATMEGA88PA-AU
The ATMEGA88PA-AU belongs to the “picoPower” series, meaning it was designed for extremely low power consumption, particularly in sleep modes. The integration of a rich set of peripherals within a single TQFP-32 package makes it a highly flexible solution for engineers. The main technical parameters of the ATMEGA88PA-AU microcontroller include:
- Architecture: 8-bit AVR processor with 131 instructions, most of which are executed in a single clock cycle.
- Flash Memory: 8 KB of in-system programmable program memory.
- EEPROM and SRAM: 512 bytes of non-volatile data memory and 1 KB of internal SRAM.
- Operating Voltage: wide supply range from 1.8 V to 5.5 V.
- Clock Frequency: up to 20 MHz at 4.5–5.5 V supply voltage.
- Peripherals: 10-bit ADC (8 channels), timers/counters with PWM modes, USART, SPI, and I2C (TWI) communication interfaces.
- Package: TQFP-32 for precise surface-mount (SMD) assembly.
The use of picoPower technology combined with advanced power-saving modes extends the operating time of battery-powered devices while maintaining full system control.
Typical Applications of the ATMEGA88PA-AU
Thanks to an optimal balance between memory capacity and the number of available input/output lines (23 programmable I/O pins), the ATMEGA88PA-AU microcontroller is widely used in a broad range of professional applications. The most common areas of use include:
- Home automation systems and smart lighting controllers,
- Wireless IoT sensor modules operating in low-power modes,
- Measurement devices and portable medical equipment,
- Motor controllers and actuator systems in robotics,
- User interfaces and control panels in consumer electronics.
The ATMEGA88PA-AU microcontroller available from Micros is a technically verified component that ensures stable operation even in demanding industrial environments.
