The Microchip ATTINY824-XFR is an 8-bit AVR microcontroller with 8KB of Flash and 1KB of SRAM, operating at up to 20MHz. It supports a supply range of 1.8V to 5.5V and is housed in a 14-TSSOP package. With integrated PWM, ADC, and brown-out detection, this MCU is engineered for demanding automotive and industrial applications.
- High-temperature tolerance (125°C): Allows placement in engine compartments or near heat sources without derating.
- 20MHz AVR core: Provides fast interrupt response for real-time control and communication.
- 14-TSSOP miniaturization: Reduces PCB area by over 50% compared to SOIC, enabling smaller products.
- Rich analog set: The 12-bit ADC and comparator eliminate external components, lowering BOM cost.
Automotive LIN Slave Nodes
The 125°C rating and 20MHz core allow it to handle LIN communication protocols for window lifts or mirror controls, with the TSSOP package fitting in small connectors.
Industrial Temperature Loggers
With its wide temperature range and ADC, it can directly interface with thermocouples (via external amplifier) and store data in Flash, operating in ovens or freezers.
Smart Lighting Drivers
The 8KB Flash supports complex dimming curves and communication stacks (e.g., DALI), while the PWM outputs drive LED drivers efficiently.
Portable Gas Detectors
Low-power sleep modes and 1.8V operation extend battery life, while the WDT ensures the sensor stays responsive in safety-critical applications.
Motor Feedback Encoders
In servo systems, the MCU can read quadrature encoder signals and send position data over a serial link, with the 20MHz speed handling high pulse rates.
Medical Wearable Monitors
The small TSSOP package and low voltage enable compact, battery-powered patches for heart rate or temperature monitoring, with reliable reset features.
