Introduction
ATMEGA8-16PU
The ATMEGA8-16PU is a high-performance 8-bit RISC microcontroller (MCU) based on Microchip's AVR architecture, engineered for cost-sensitive, feature-rich embedded systems. With a 16MHz maximum clock frequency, 8KB in-system programmable (ISP) flash memory, and compact 28-pin DIP package, it balances processing power, storage capacity, and ease of integration—ideal for industrial control, consumer electronics, automotive systems, and educational projects.
Core Functional Characteristics
- 8-Bit AVR RISC Core: Harvard architecture with 131 instructions (most executed in 1 clock cycle), enabling 16 MIPS performance at 16MHz for real-time control tasks.
- Flexible Non-Volatile Storage: 8KB ISP flash memory, 1KB SRAM, and 512B EEPROM with 100,000+ write cycles and 100+ years data retention.
- Rich Peripheral Interface Set: Includes UART, SPI, I2C, 3x 8-bit timers with PWM, and 10-bit ADC with 8 channels.
- Low-Power Operation: Multiple power-saving modes with typical current of 3.6mA (active) and 1μA (Power-Down).
- DIP28 Package: Through-hole 28-pin design with 23 GPIO pins for easy prototyping and integration.
