The Microchip ATMEGA808 is an 8-bit AVR microcontroller in a 28-SSOP package. It operates from 1.8V to 5.5V at up to 20MHz. Featuring 8KB Flash and 1KB RAM, it includes Brown-out Reset, POR, and WDT. Its extended temperature range makes it suitable for automotive and industrial applications.
- Extended temperature range (-40°C to 125°C) supports harsh environments.
- Low-voltage operation (1.8V) enables battery-powered designs.
- Integrated BOR and WDT improve system reliability without extra parts.
- Compact SSOP-28 package balances pin count with board space.
Automotive Sensor Nodes
The -40°C to 125°C range and robust BOR make it ideal for engine bay sensors (pressure, temperature) communicating over LIN or I2C.
Industrial Process Controllers
With 8KB Flash and 1KB RAM, it can run PID loops for temperature control in plastic molding machines, with WDT ensuring fail-safe operation.
Smart Agriculture Probes
Low-power sleep modes and 1.8V operation allow soil moisture probes to run for months on coin cells, waking periodically to measure and transmit data.
HVAC Zone Controllers
The 28-pin SSOP package fits into compact thermostat backplates, managing damper actuators and reading multiple thermistors.
Battery Management Systems
Its BOR and WDT protect against undervoltage in 48V e-bike batteries, monitoring cell voltages and controlling balancing FETs.
Portable Data Loggers
The AVR core's efficient instruction set and 1KB RAM allow logging of environmental data to external EEPROM over SPI.
