ATMEGA 16A
ATMEGA 16A
ATMEGA 16L Vs ATMEGA 16A
Difference between these 2 ICs :
Operating Voltage
For ATMEGA16A or plain 16 :+4.5 to +5.5 V (+5.5V being absolute maximum) For ATMEGA16L : +2.7 to 5.5V (+5.5V being absolute maximum)
External Oscillator 0-8MHz for ATMEGA16L 0-16MHz for ATMEGA16A
Otherwise these 2 ICs are same
