Description
The ATmega8A is a high-performance 8-bit AVR microcontroller with advanced RISC architecture, designed for efficient processing in low-voltage applications. With 8 KB of Flash memory, 512 bytes EEPROM, and 1 KB SRAM, it supports real-time applications with ease. Featuring UART, SPI, and I2C interfaces, internal and external interrupts, and multiple sleep modes, it’s ideal for embedded systems, automation, and control systems requiring precise timing, low power usage, and flexible interfacing.
Features:
- Advanced 8-bit AVR RISC architecture
- 130 powerful instructions with 32 x 8 general-purpose registers
- Up to 16 MIPS throughput at 16 MHz
- 23 programmable I/O lines
- Three PWM channels, one comparator
- 8-channel 10-bit ADC
- Two 8-bit timers and one 16-bit timer
- On-chip 2-cycle hardware multiplier
- Internal calibrated RC oscillator
- Internal and external interrupt support
- Supports UART, SPI, and I2C communication
- Five power-saving sleep modes
