Programming Times
The time required to implement each of the six programming stages can
be broken into the following two elements:
■
■
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 7000S Device
The time required to program a single MAX 7000S device in-system can
be calculated from the following formula:
where: t
The ISP times for a stand-alone verification of a single MAX 7000S device
can be calculated from the following formula:
where: t
t PROG
t
VER
A pulse time to erase, program, or read the EEPROM cells.
A shifting time based on the test clock (TCK) frequency and the
number of TCK cycles to shift instructions, address, and data into the
device.
