6.12 Flash Timing

Table 6-43. Flash Endurance for A and S Temperature Material(1)

			MIN	TYP	MAX	UNIT
Nf	Flash endurance for the array (write/erase cycles)	0°C to 85°C (ambient)	20000	50000		cycles
NOTP	OTP endurance for the array (write cycles)	0°C to 85°C (ambient)			1	write

(1)Write/erase operations outside of the temperature ranges indicated are not specified and may affect the endurance numbers.

Table 6-44. Flash Endurance for Q Temperature Material(1)

			MIN	TYP	MAX	UNIT
Nf	Flash endurance for the array (write/erase cycles)	–40°C to 125°C (ambient)	20000	50000		cycles
NOTP	OTP endurance for the array (write cycles)	–40°C to 125°C (ambient)			1	write

(1)Write/erase operations outside of the temperature ranges indicated are not specified and may affect the endurance numbers.

Table 6-46. Flash/OTP Access Timing

	PARAMETER	MIN	TYP MAX	UNIT
ta(fp)	Paged flash access time	36		ns
ta(fr)	Random flash access time	36		ns
ta(OTP)	OTP access time	60		ns

Equations to compute the Flash page wait-state and random wait-state in Table 6-47are as follows:

Flash Page Wait-State+ ￿￿	ta(fp)			￿* 1￿(round up to the next highest integer) or 0, whichever is larger
	tc(SCO)
Flash Random Wait-State+ ￿￿			ta(fr)		￿* 1￿(round up to the next highest integer) or 1, whichever is larger
		t	c(SCO)

Equation to compute the OTP wait-state in Table 6-47is as follows:

￿￿ta(OTP) ￿ ￿

OTP Wait-State+* 1 (round up to the next highest integer) or 1, whichever is larger
