15 / 46 page Altera Corporation 15 MAX 3000A Programmable Logic Device Family Data Sheet By combining the pulse and shift times for each of the programming stages, the program or verify time can be derived as a function of the TCK frequency, the number of devices, and specific target device(s). Because different ISP-capable devices have a different number of EEPROM cells, both the total fixed and total variable times are unique for a single device. Programming a Single MAX 3000A Device The time required to program a single MAX 3000A device in-system can be calculated from the following formula: where: tPROG = Programming time tPPULSE = Sum of the fixed times to erase, program, and verify the EEPROM cells CyclePTCK = Number of TCK cycles to program a device fTCK = TCK frequency The ISP times for a stand-alone verification of a single MAX 3000A device can be calculated from the following formula: where: tVER =Verify time tVPULSE = Sum of the fixed times to verify the EEPROM cells CycleVTCK = Number of TCK cycles to verify a device tPROG tPPULSE Cycle PTCK f TCK -------------------------------- + = tVER tVPULSE Cycle VTCK fTCK -------------------------------- + = |
