Latest Patents

One of Robert W. Sparks' significant patents is titled "Microcontroller having an EPROM with a low voltage program inhibit." This invention features an on-chip electrically erasable programmable read-only memory (EEPROM) that is user programmable via a programming register. The microcontroller incorporates a low voltage program inhibit (LVPI) circuit, which is integrated with the existing EEPROM design. This integration allows for the protection of the EEPROM without disabling the entire data processing system. The LVPI circuit inhibits the use of the EEPROM programming register when the supply voltage falls below a predetermined level, thus preventing the CPU from programming or erasing the EEPROM. A comparator within the LVPI circuit compares a precision reference voltage to a voltage derived from the power supply, providing an output signal to the EEPROM programming register. During normal operation, the comparator output is a logic low, enabling programming or erasing of the EEPROM. However, when the supply voltage is below the safe level, the comparator output becomes a logic high, which sets a control bit in the programming register, disabling further EEPROM programming.
