eeprom types 93C56 /93LC56 help

[cyrixcard]

I have original carprog.

Some toyota cars with 4D key have 93LC66 eeprom and some have 93C66

I have camry 2009. The Immobox has eeprom 93C66.

But carprog toyota show 93LC66/texas Crypto

My question is 93C66 and 93LC66 are they same?

Is 93C56 also same as 93LC56

Both type 93C66 93LC66 same function & capacity.
Only different supply voltage.

Supply voltage:
4.5 ~ 5.5 Volt DC for 93Cxx (93C46, 56, 66, 76, 86)
2.5 ~ 5.5 Volt DC for 93LCxx (93LC46, 56, 66, 76, 86)
1.8 ~ 5.5 Volt DC for 93AAxx (93AA46, 56, 66, 76, 86).
