MAX 9000 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 9000 Device

The time required to program a single MAX 9000 device in-system can be

calculated from the following formula:

tPR OG = tPP ULSE + -C----y---c-f--Tl---e--CP----KT----C-----K--

where: tPROG

tPPULSE

CyclePTCK

fTCK

= Programming time

= Sum of the fixed times to erase, program, and

verify the EEPROM cells

= Number of TCK cycles to program a device

= TCK frequency

The ISP times for a stand-alone verification of a single MAX 9000 device

can be calculated from the following formula:

tVER = tVPULSE + C-----y---c--f-l-T-e---CV----K-T----C----K---

where: tVER

= Verify time

tVPULSE = Sum of the fixed times to verify the EEPROM cells

CycleVTCK = Number of TCK cycles to verify a device
