The Microchip ATTINY1634R-SU is an 8-bit AVR MCU with 16KB flash and 1KB RAM, operating at 12 MHz. It includes PWM, BOR, and WDT in a 20-SOIC package, designed for low-power embedded control.
- Pin-compatible: Drop-in replacement for other ATtiny1634 variants.
- Low power: 1.8V operation reduces energy consumption.
- Compact size: 20-SOIC fits space-constrained PCBs.
- Reliable operation: BOR and WDT enhance system stability.
Battery Monitors
Low voltage operation and ADC channels enable accurate voltage/current monitoring in portable electronics.
LED Displays
PWM outputs drive multiplexed LED matrices in small signage and notification devices.
Environmental Loggers
1KB RAM buffers sensor readings before writing to external EEPROM in weather stations.
Motor Speed Controllers
12MHz processing and PWM generate smooth control for small cooling fans.
Access Control
Secure boot and WDT support keypad-based entry systems with anti-tamper features.
Medical Wearables
Compact SOIC package and low power suit continuous glucose monitors and drug pumps.
