The Microchip ATMEGA808-XU is an 8-bit AVR microcontroller in a compact 28-SSOP package. It delivers 20MHz performance with 8KB Flash and 1KB SRAM, operating from 1.8V to 5.5V. Integrated Brown-out Reset, POR, and WDT enhance system reliability. This MCU is designed for cost-sensitive embedded control applications requiring low power and robust operation.
- Wide voltage range (1.8V-5.5V): Enables flexible power supply design from single-cell batteries to 5V regulated rails.
- High integration: On-chip Brown-out Reset, POR, and WDT reduce external component count and improve system reliability.
- Efficient AVR core: 20MHz speed provides ample processing power for real-time control tasks.
- Compact SSOP package: Saves PCB area for space-constrained designs.
Battery-Powered Sensor Nodes
The 1.8V minimum supply voltage allows direct operation from a single-cell battery, while the WDT ensures reliable wake-up and reset in low-power sleep modes.
Industrial Control Panels
With a 20MHz AVR core and 8KB Flash, it can handle real-time control loops for relay switching and status monitoring in 24V industrial environments.
Portable Medical Monitors
The wide voltage range and low-power features enable continuous vital-sign monitoring with long battery life, and the SSOP package saves board space.
Automotive Interior Lighting
Operating from 5V automotive rails, the Brown-out Reset ensures safe microcontroller startup during cranking voltage dips.
Smart Home Thermostats
Its 1KB SRAM supports simple user interface logic and sensor reading, while the 28-pin package integrates well with analog front-ends.
Consumer Appliances
The 8KB Flash is ideal for storing calibration data and control algorithms for washing machines or microwave ovens.
