Latest Patents

One of Thomas I Elmer's latest patents is for a microcontroller device having a remotely programmable EPROM. This invention describes a microcontroller device on a single integrated circuit that includes a central processing unit, an associated data bus, and an electrically-programmable nonvolatile memory. The nonvolatile memory contains the applications program and can be remotely programmed via a communication port, such as a universal asynchronous receiver/transmitter (UART) device, utilizing a separate host computer. Additionally, a second nonvolatile memory is provided, which contains a control program executed by the central processing unit to carry out the programming of the electrically-programmable nonvolatile memory.

Another significant patent focuses on an encryption method that selects certain bytes of data stored in a specific on-chip memory as encryption keys. These chosen bytes are used to encrypt themselves and all remaining data in the memory. This technique ensures that the user does not need to provide or safeguard a separate set of key bytes, thus optimizing silicon area usage. The method also enhances security, as an intruder would require specific pieces of the original data to decipher the encrypted results.
