Does someone know details about the maximum clock of EEPROM?

According to LPC4357 user manual UM10503.pdf (version 1.8 from 28. January 2014, table 1153)
"EEPROM BASE_M4_CLK CLK_M4_EEPROM up to 204 MHz"

According to errata sheet ES_LPC435X_3X_2X_1X_FLASH.pdf (Rev. 5 — 15 August 2014):
"
Chapter 3.2 EEPROM.2
A 16 kB EEPROM is available on these parts which operates up to 180 MHz.
"

What is correct? Must CLK_M4_EEPROM be limited to 180 MHz or can it be driven with 204 MHz?

Or is it due to changes in register RWSTATE and WSTATE, so it can be used with 204 MHz instead of 180 MHz?

Hi,

The maximum clock of EEPROM is 204 Mhz as mentioned in the UM.
Thanks for pointing out the mistake in Errata sheet. It will updated in the next revision.

Thanks,
