Read/Write Times

For double read and compare:
Data carrier with 32 byte blocks
No. of bytes Read time [ms]
from 0 to 31 110
for each additional
32 bytes add 120
from 0 to 255 = 950
Including readback and compare:
Data carrier with 32 byte blocks
No. of bytes Write time [ms]
from 0 to 31 110 + n * 10
for 32 bytes or more y * 120 + n * 10
n = number of contiguous bytes to write
y = number of blocks to be written
Example:
Read 17 bytes starting at address 187. Data carrier with 32 byte blocks.
Blocks 5 and 6 have to be accessed, because start address 187 is in block 5 and end address 203 is in block 6.
t = 2 * 120 + 17 * 10 = 410
The indicated times apply after the data carrier has been recognized. Otherwise an additional 45 ms
must be added to allow for the energy field to be established until the data carrier is recognized.
Read/Write Times
Read Times for 1 Block with double read and compare:
Data carrier with 32 byte blocks
No. of bytes Read time [ms]
from 0 to 3 14
for each additional
byte add 3.5
from 0 to 31 112
m = highest address to be read
Formula: t = (m + 1) * 3.5 ms
Example: Read 11 bytes starting at address 9. Hence the highest address to be read is 19.
This results in 70 ms.
Including readback and compare:
Data carrier with 32 byte blocks
No. of bytes Write time [ms]
from 0 to 3 14 + n * 10
for each additional
byte add 3.5
n = Number of contiguous bytes to be written
The indicated times apply after the data carrier has been recognized. Otherwise an additional 45 ms
must be added to allow for the energy field to be established until the data carrier is recognized.
Data carrier with 64 byte blocks
No. of bytes Read time [ms]
from 0 to 63 220
for each additional
64 bytes add 230
from 0 to 2047 = 7350
Data carrier with 64 byte blocks
No. of bytes Write time [ms]
from 0 to 63 220 + n * 10
for 64 bytes or more y * 230 + n * 10

from 0 to 63 224
Data carrier with 64 byte blocks
