Configure the FLEX Device
You can use any Micro-Controller to configure the
FLEX device
– the main idea is clocking in ONE BIT of configuration data
per CLOCK
– start from the BIT 0
The total Configuration time
– e.g. 10K10 need 15K byte configuration file
• calculation equation
– 10K10 * 1.5 = 15Kbyte
– configuration time for the file itself
• 15*1024*8*clock = 122,880Clock
• assume the CLOCK is 4MHz
• 122,880*1/4Mhz=30.72msec

Total Configuration time
Total Configuration time (10K10)
– POR(Power On Reset) + programming bit time + error/status check
time + 10 extra clock
– POR + 30.72msec + error/status check time + 10 extra clock
– 100ms + (error/status check + 10 extra clock) + 30.72msec
= 130.72msec + (error/status check + 10 extra clock)
= ~150msec
100msec + (error/status check + 10 extra clock) + 30.72msec

How about 10K100
10K100 :
(1) 100 * 1.5Kbyte = 150Kbyte
= 1200Kbits
(2) assume DCLK = 6MHz
(3) configuration of the POF file itself = 1200K/4Mhz
= 195msec
(4) Total configuration time = POR + (3) + error/checking + 10 CLOCKS
= 295msec + error/checking + 10 CLOCKS
= ~350msec
