Altera Corporation
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: t
