This application note provides a detailed description of the part numbering scheme of Serial EEPROM products. The part numbering scheme consists of a maximum of 13 digits grouped into nine fields (A to H), as shown in Table 1: Serial EEPROM part numbering scheme on page 1Table 1. Fields A to C represent the product identifiers and fields D to H the product options. The “-” character is used to separate the identifiers from the options. An additional “/” followed by two digits are used by ST to aid traceability, and might appear on some documents at the bottom of the Ordering information scheme table under Process. This information offers the die and technology references (for temperature range 3 devices) and can be ignored for temperature range 6 devices.
