Abstract: PROBLEM TO BE SOLVED: To provide a system, method, and a device for programming so that an EEPROM having non-volatile stored data has reliability. SOLUTION: This electronic system comprises a microcontroller core logic 102, an EEPROM 112, an EEPROM programming logic 114, and a charge pump 116 for generating EEPROM programming voltage, programming voltage generated by the charge pump is compared with reference voltage by a voltage comparator 118, when the programming voltage is a desired value or more, the programming logic is enabled so as to perform programming processing on the EEPROM, when the programming voltage is a desired value or less, the programming logic is suppressed to perform programming processing on the EEPROM.

Abstract: A radio frequency transponder device in an integrated circuit package requires only one dedicated pin for connection to a parallel resonant tuned circuit for receiving a remote signal. The one dedicated pin has a capacitor which blocks direct current (DC) flow and allows independent DC biasing of a radio frequency amplifier for increased signal amplification gain. Another package pin used for common power or ground connections supplies the second connection to the resonant tuned circuit. Multiple transponder inputs may be implemented in a single integrated circuit package using only one dedicated pin per input plus one common pin which may be used for another purpose, such as a power or a ground connection.

Abstract: An electronic system, comprising a digital processor and an EEPROM, has circuit logic and program software or firmware for determining if a programming voltage level is sufficient for reliably programming the EEPROM. A charge pump is enabled and generates a voltage used for programming of the EEPROM. The enabled charge pump thereby loads a battery power supply. In addition, a test load may be connected to the output of the charge pump to simulate the EEPROM load during a programming operation to the EEPROM. The charge pump output voltage is measured to determine if at least a desired voltage value is obtained. Once the charge pump voltage level has been pre-qualified for the desired voltage value, an actual programming operation to the EEPROM may be performed. If the voltage level does not reach the desired value then a programming operation is inhibited and the electronic system may alarm or shut down operation. The charge pump voltage level is a good indication and measure of battery charge condition under actual EEPROM programming load conditions.
