Introduction the ACEx (Arithmetic Controller Engine) family of programmable integrated circuits is designed for applications requiring high performance, low power, and small size. The ACEx family supports in-circuit programming of the code EEPROM array, the data EEPROM array, and initialization registers 1 and 2. In-circuit programming of an ACEx device is accomplished through a 4-pin interface. Data is shifted serially in and out of the device using a 32-bit command/response word.

This 32-bit command and response word contains all the necessary information to program data to the EEPROM arrays or the initialization register. This application note provides a detailed description of the programming interface, the 32-bit command/response word, and the programming procedures. In addition, this application note also provides all timing specifications for the programming signals.
