Abstract :
A new low-power EEPROM circuit for sensor interface circuit is introduced in this paper. The calibration data and parameter setting data stored in EEPROM can be reloaded automatically by the power-on-reset (POR) technique when the power is on. The module only consumes power during power-on-reset and data changing by status optimization and low-power design. This EEPROM circuit design has been used in a MEMS accelerometer readout circuit verified by 0.35μm CMOS EEPROM process. The results are satisfying in that the module can write and store 25bit data and automatically reloads data within 0.1μs after power-on and then turns to low power mode.
