On some models (those with TX19A MPU), you can read the EEPROM, with the mpu_dump module. The 70D is not one of them - it uses F74966A, just like 100D and 700D. The 5D3 and 6D use F74965A, while the 650D and EOSM use F74964A.

[...] Renesas SH7231 series microcontrollers (also known as the Renesas semiconductor component with the package marking "F74966A" or the die marking "R5F72315A") [...]

Another mystery cleared, thanks Danieel
