Param. No.	Symbol	Characteristics		Min.	Typical	Max.	Units	Conditions
NVM_1	F_RETEN	Flash data retention		20	—	—	Yrs	Under all conditions less than absolute maximum ratings specifications
NVM_3	EP	Cell endurance (Flash erase and Write operation)		20k	—	—	Cycles
NVM_5	FREAD	Flash read	2 wait states	—	—	—	MHz	V_DDIO = 3.3V
NVM_7	TFPW	Program cycle time	Write page	4	—	6	ms	V_DDIO = 1.9V
NVM_9	TCE	Chip erase cycle time	Erase chip	37	—	42	ms	V_DDIO = 1.9V
NVM_15	TFEP	Page erase time	Erase page	6	—	8	ms	—
Note: The maximum FLASH operating frequencies are given in the table above but are limited by the Embedded Flash access time when the processor is fetching code out of it. This field defines the number of Wait states required to access the Embedded Flash Memory.
