EM4569 is completely compatible with em4469. however, EM4569 has bumped enlarged pads intended for direct connection of coil to big bumps. EM4569 also has an extended reading range which makes it particularly suitable for animal tracking applications. features ? extended reading range (EM4569) ? 512 bit eeprom organised in 16 words of 32 bits ? 32 bit password read and write protection ? 32 bit unique identification number (uid) ? 10 bit customer code ? iso 11784 / 11785 standard compliant ? bumped enlarged pads (EM4569 only) ? lock feature convert eeprom words in read only ? multi-purpose encoding (manchester, biphase, miller, psk, fsk) ? multi-purpose data rate from 1 up to 32k baud ? 100 to 150 khz frequency range ? on-chip rectifier and voltage limiter ? no external supply buffer capacitor needed ? -40 to +85 c temperature range ? very low power consumption ? resonant capacitor integrated on chip (330pf, 250pf or 75pf mask option) applications ? access control ? animal identification according to iso fdx-b (EM4569) ? material logistics typical operating configuration fig. 1 block diagram fig. 2 em microelectronic - marin sa c1 em4469 EM4569 l c2 modulator logic eeprom clock extractor data extractor v pos v ss power supply reset power on reset coil1 c r c buf coil2
