The Microchip ATTINY1626-XU is a low-power 8-bit AVR microcontroller in a 20-pin SSOP package. It features 16KB Flash, 2KB SRAM, and operates at 20MHz. With a 12-bit differential ADC with PGA, 10-bit DAC, and capacitive touch support, it provides a high level of analog integration for space-constrained, battery-powered designs.
- High Analog Integration: 12-bit ADC with PGA and 10-bit DAC reduce external components.
- Low Power with Fast Wake-up: Wake from sleep in under 10µs, enabling duty-cycled sensor nodes.
- Flexible Package Option: SSOP is easier for hand-soldering and prototyping compared to QFN.
- Wide Voltage Range: 1.8V-5.5V supports both Li-ion (3.7V) and alkaline (1.5V x2) power sources.
Industrial Process Control
The SSOP package with 0.65mm pitch is easier to route on 2-layer boards, making it ideal for PLC analog output modules using the 10-bit DAC.
Medical Device Sensors
Its 12-bit differential ADC with PGA can accurately measure biopotential signals (ECG/EMG) with proper front-end filtering.
Smart Agriculture Nodes
With low sleep current and 1.8V operation, it can run on solar-charged batteries for soil moisture monitoring.
Audio/Visual Effects
Use the 20MHz speed and PWM to generate simple sound effects or drive LED matrices in entertainment systems.
Security Systems
Its robust I/O and WDT make it reliable for door/window sensor controllers with tamper detection.
Portable Instrumentation
The SSOP package is thinner than QFN, enabling slim handheld devices like digital calipers or multimeters.
