摘要： An RFID transponder chip includes at least one antenna to pick-up and transmit radio-frequency signals, a rectifier to store charge on at least one capacitor at a rectified voltage from the picked-up radio-frequency signals, a power-on reset circuit to maintain a logic unit in a reset state if the rectified voltage level is less than a power-on reset or wake-up voltage of the power-on reset circuit for operating the logic unit. The RFID transponder chip further includes a non-volatile memory, in which are stored one or several trim values. Said non-volatile memory is directly connected to the power-on reset circuit to be able to provide at least one trim value to trim the power-on reset circuit at a rectified voltage level below a wake-up voltage level.
