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 1
This document describes the part numbering scheme for Serial EEPROM products from STMicroelectronics. The scheme consists of a maximum of 13 digits grouped into nine fields (A to H), with an optional 14th digit for die process. Fields A through C identify the product line, device type, and memory capacity, while fields D through H specify operating voltage, package type, temperature grade, packing option, and plating technology.
| Part numbering scheme | maximum of 13 digits grouped into nine fields |
|---|---|
| Product line code | M for Memory |
| Voltage range code W | 2.5V to 5.5V |
| Temperature range grade 3 | -40 °C to +125 °C |
| Package code BN | PSDIP8 standard |
The letter M represents the product line type, which is Memory.
Code W indicates an operating voltage range of 2.5V to 5.5V.
Grade 3 is certified for the automotive industry with a temperature range of -40 °C to +125 °C.
