TABLE 4-3:

VALUE DEFINITIONS IN THE OTP EPROM

TEOD 8 coded bytes

typ: 5,20,35,50,80,113,150,150

Range: 1-255 per byte

EOD Temperature boundaries, 8 increasing values of temperature coded as TEODx = (Tcelsius*10+200)/4

CEOD 8 coded bytes

typ: 19,32,48,64,77,90,109,109

Range: 1-255

EOC C-rate boundaries, 8 increasing values of C-rates coded:

CEODx = C-rate * (256/28/RF), where RF is the Rate Factor (RFactor) OTP EPROM parameter.

For RF = 7, CEODx = C-rate * 64. Thus, a value of 32 is one-half C, etc.

FCCP coded %

typ: 50,25,12,8,0,0,0

Range: 1-255

Unusable residual capacity before save to disk, corresponding to temperature. 255 = 100%

VEOD coded

typ: 75

Range: 1-255

End of discharge voltage, voltage = 8000 + 4 * VEOD. Pack voltage at which save to disk is signaled.
