Altera CPLD EPM7128ALC Embedded Eeprom Program Recovery is a process to unlock security fuse bit of EPM7128 CPLD chip and extract eeprom firmware from CPLD’s secured memory in the format of JED;
Because MAX 7000A devices can be used in a mixed-voltage environment, they have been designed specifically to tolerate any possible power-up sequence. The VCCIO and VCCINT power planes can be powered in any order.
Signals can be driven into MAX 7000AE devices before and during power- up (and power-down) without damaging the device.
Additionally, MAX 7000AE devices do not drive out during power-up when breaking altera cpld epm7064aetc protection. Once operating conditions are reached, MAX 7000AE devices operate as specified by the user.

MAX 7000AE device I/O pins will not source or sink more than 300 µA of DC current during power-up. All pins can be driven up to 5.75 V during hot-socketing, except the OE1 and GLCRn pins.
The OE1 and GLCRn pins can be driven up to 3.6 V during hot-socketing. After VCCINT and VCCIO reach the recommended operating conditions, these two pins are 5.0-V tolerant which can be used for recover embedded eeprom firmware of EPM7032VTC cpld chipset.
EPM7128A and EPM7256A devices do not support hot-socketing and may drive out during power-up.
