The Microchip ATMEGA169PA-MCH is a high-performance 8-bit AVR microcontroller designed for applications requiring efficient processing and direct LCD drive capability. Operating from 1.8V to 5.5V and up to 16MHz, it integrates 16KB of flash memory and 1KB of SRAM. The 64-VQFN package includes an exposed pad for thermal management, and the device features brown-out detection, power-on reset, PWM, and a watchdog timer for robust operation in demanding environments.
- Integrated LCD Driver: Directly drives segment LCDs without external ICs, reducing BOM cost and board space.
- Wide Voltage Range (1.8V-5.5V): Supports both 3.3V and 5V systems, simplifying power supply design.
- Low-Power AVR Core: Optimized for battery-powered devices, extending operational life.
- Robust Protection Features: Includes brown-out reset and watchdog timer for reliable operation in harsh environments.
Battery-Powered Metering Systems
The 1.8V minimum supply voltage and low-power AVR core enable long battery life in utility meters, while the integrated LCD driver directly interfaces with display panels.
Portable Medical Monitors
With a 16MHz clock and 16KB flash, it handles real-time vital sign sampling and drives compact LCD readouts, all within a small 64-VQFN footprint.
Industrial Process Displays
The built-in brown-out detection and watchdog timer ensure reliable operation in noisy industrial environments, while the LCD controller simplifies local status readouts.
Home Automation Controllers
PWM channels allow dimming and motor control, and the wide voltage range accommodates both 3.3V and 5V logic, simplifying system integration.
Automotive Aftermarket Gauges
