16 MHz, 32 KB Flash, 40-pin DIP — the through-hole AVR that still runs production lines
The Microchip ATMEGA32-16PU is an 8-bit AVR microcontroller in the ATmega family, clocked at 16 MHz and packaged in a 40-pin DIP with 0.600-inch row spacing — the same footprint that's been socketed on industrial controllers, test fixtures, and hobbyist boards for decades.
Peripheral set — what the 32 I/O and ADC bring to the board
On-chip peripherals include brown-out detection, power-on reset, PWM outputs, and a watchdog timer, so a motor-drive or heater-controller board can run with minimal external supervision.
It is still in standard production, so there is no last-time-buy deadline to manage. ROHS3 compliant, and the 40-PDIP package is widely stocked across distribution channels.
