ATMEGA16A-AU
Microchip TechnologyATMEGA16A-AU is an 8-bit AVR microcontroller from Microchip in a 44-pin TQFP package (tray supply), with 16 KB of in-system-programmable Flash, 512 B EEPROM and 1 KB SRAM, running up to 16 MHz from 2.7 V to 5.5 V. It remains a maintenance and education staple: 32 programmable I/O lines, an 8-channel 10-bit ADC, USART, SPI and TWI interfaces and a deep base of legacy AVR firmware mean existing ATmega16-generation designs can stay in production without a respin. Selection advice: AU is the TQFP tray code - choose ATMEGA16A-AUR for tape-and-reel supply; the A generation supersedes the original ATmega16 for new orders, and close-but-not-total pin compatibility means the migration notes should be checked before substituting into an old BOM. The industrial operating range is -40 to +85 °C. Parameters verified against the Microchip ATmega16A datasheet (Atmel-8154C) ordering information.
