MAX 7000B Programmable Logic Device 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 7000B Device
The time required to program a single MAX 7000B device in-system can
be calculated from the following formula:
where:
t
PROG
= Programming time
= Sum of the fixed times to erase, program, and
verify the EEPROM cells
Cycle
PTCK
= Number of
TCK
cycles to program a device

The ISP times for a stand-alone verification of a single MAX 7000B device
can be calculated from the following formula:
where:

= Verify time
= Sum of the fixed times to verify the EEPROM cells
