specification of word/buffer programming time for GL-P Parallel NOR

[NaMo_1534561]

Hello,

Could you provide the Maximum word programming time and the Maximum buffer programming time for S29GL256P ?

MPN:  S29GL256P90TFCR20

CFI flash manufacture ID : xx01h/1h
CFI flash device ID : 227Eh/7Eh
CFI flash extended device ID : 2222h/22h
Typical word programming time : 60us
Maximum word programming time :  ?
Typical buffer programming time : 15us/word
Maximum buffer programming time :  ?

Customer need to use this specification for FPGA boot configuration.
I can find a typical time for single and buffer programming in the datasheet, but can't find a max value.

Best Regards,

Naoaki Morimoto

Hello Naoaki,

Thank you for contacting Cypress Technical Support, an Infineon Technologies Company.

The word/buffer programming time can be vary a lot depending on Voltage supply level, Temperature, number of programing bit(s). Our recommendation is to use the data polling to monitor the programming operation progress.

Example :-- DQ7, DQ6, DQ5, DQ2, and DQ1 should be monitored to determine the device status during Write Buffer Programming.
