In the Infineon 45-nm MIRRORBIT™ SEMPER™ NOR flash memory device, the top marking has four fields: Device family, speed option, temperature grade, and model number. The speed option and temperature grade can be decoded from the two characters of the SEMPER™ NOR flash’s device top marking. See Chapter 11, Ordering Information in the SEMPER™ NOR Flash datasheet (Doc. No. 002-12345) for valid combinations.

Model number

25HL512T

P, DP = 133 MHz SDR and 66 MHz DDR

 

F, FA = 166 MHz SDR and 102 MHz DDR

 

S, DS = 166 MHz SDR and 83 MHz DDR

 

I = Industrial (-40°C to +85°C)

V = Industrial Plus (-40°C to +105°C)

A = Automotive, AEC-Q100 Grade 3 (-40°C to +85°C)

B = Automotive, AEC-Q100 Grade 2 (-40°C to +105°C)

M = Automotive, AEC-Q100 Grade 1 (-40°C to +125°C)

01 = BGA / WSON 6 x 8 mm, SOIC – 16 packages

03 = BGA 8 x 8 mm package

 

The 65-nm device family has five fields: Device family, speed option, temperature, package material, and model number.

Each device family's datasheet contains the model number.

Speed option omitted because there’s only one speed option for this device family.

AB= 108 MHz SDR and 54 MHz DDR

I = Industrial (-40°C to +85°C)

V = Industrial Plus (-40°C to +105°C)

A = Automotive, AEC-Q100 Grade 3 (-40°C to +85°C)

B = Automotive, AEC-Q100 Grade 2 (-40°C to +105°C)

M = Automotive, AEC-Q100 Grade 1 (-40°C to +125°C)

A, AG = 133 MHz

D, DP = 66 MHz DDR

 

FL128S

FL256S

FL512S

FL01GS

A, AG = 133 MHz

D, DP = 66 MHz DDR

S, DS = 80 MHz DDR

FS01GS

A, AG = 133 MHz

D, DS = 80 MHz DDR

 
For example, the FS512SDVF01 device top marking is shown in the Figure 1. The top marking shows that the speed option is D, DP = 66 MHz DDR, and the temperature grade is V = Industrial Plus (-40°C to +105°C).
