Audio Amplifier Circuit Using STK439

Electronic circuit to fill the IC EEPROM MEMORY Based on its memory capacity is usually written with a number 24CXX, For XX is its capacity in Kbit. Example: 24C08 means its capacity 8 kilobits. In many stores that sell the number 24C01, 24C02, 24C04, 24C08, 24C16, 24c32 which sold in its data store is empty. […]
