![]() ![]() The data connection to the PC runs via the hardware UART interface of the ATmega transfering the data in binary format with up to 1 Mbps. Address and data bus are simultaneously driven to achieve the maximum data transfer rate. The data bus is controlled directly via the pins of the ATmega. The address bus of the EEPROM (up to 15 bit) is controlled via two daisy-chained 74HC595 shift registers using hardware SPI 8 Mbps. The heart of the EEPROM programmer is an ATmega8 microcontroller. Utilizing the fast page write mode of the EEPROM.Hardware UART with 1 Mbps for data transfer to/from PC via USB 2.0.Hardware SPI with 8 Mbps to control address bus via shift registers.Possibility to access the programmer via a serial monitor.Parallel EEPROM Programmer for 28C64B and 28C256 featuring: ![]() Parallel EEPROM Programmer based on ATmega8 ![]()
