I couldn't find these numbers in my databook.
I guess it's the same as following one.

"F" must stand for "Fujitsu".  The last 2 digits, 45, indicates that
its access time is 450nSec.  So that, you may use this under less than
2.2MHz clock. Programing voltage (Vpp) is 12volts.  Its pinouts is as
follows.
	     ___________
	 A7 |1   |_|  24| Vdd(+5v)
	 A6 |           | A8
	 A5 |           | A9
	 A4 |           | A11
	 A3 |           | OE/Vpp
	 A2 |           | A10
	 A1 |           | CS
	 A0 |           | D7
	 D0 |           | D6
	 D1 |           | D5
	 D2 |           | D4
   (GND)Vss |12_______13| D3


Hope this helps.
