54 / 70 page  SII EEPROM Interface (I²C) III-44 Slave Controller – ET1200 Hardware Description 8 SII EEPROM Interface (I²C) For details about the ESC SII EEPROM Interface refer to Section I. The SII EEPROM Interface is intended to be a point-to-point interface between ET1200 and I²C EEPROM. If other I²C masters are required to access the I²C bus, the ET1200 must be held in reset state (e.g. for in-circuit-programming of the EEPROM), otherwise access collisions will be detected by the ET1200. 8.1 Signals The EEPROM interface of the ET1200 has the following signals: EtherCAT device EEPROM_DATA EEPROM_CLK EEPROM_SIZE Figure 22: I²C EEPROM signals Table 46: I²C EEPROM signals Signal Direction Description EEPROM_CLK OUT I²C clock EEPROM_DATA BIDIR I²C data EEPROM_SIZE IN EEPROM size configuration The pull-up resistors for EEPROM_CLK and EEPROM_DATA are integrated into the ET1200. EEPROM_CLK must not be held low externally, because the ET1200 will detect this as an error. 8.2 Timing specifications Table 47: EEPROM timing characteristics Parameter Typical Comment 1 Kbit-16 Kbit 32 Kbit-4 Mbit tClk ~ 6.72 µs EEPROM clock period (fClk ≈ 150 kHz) tWrite ~ 250 us ~ 310 µs Write access time (without errors) tRead a) ~ 680 µs b) ~ 1.16 ms a) ~ 740 µs b) ~ 1.22 ms Read access time (without errors): a) 4 words b) configuration (8 Words) tDelay ~ 168 ms Time until configuration loading begins after Reset is gone |
