||
| ## Unique Serial ID - Hidden Serial Number | ||
|
|
||
| The datasheet of the Atmega328pb chip has a section 'Serial Number' how explain every chip have a unique device ID with 10 bytes. <br/> | ||
|
|
||
| The datasheet of the Atmega328p chip does not say anything about the serial number, but I tested using the same Z-pointer Address on the datasheet of the Atmega328pb. <br/> | ||
|
|
||
| Apparently, the chip Atmega328p have a hidden serial number with 9 bytes, and others AVR Microcontroller maybe too, like the table below. <br/> | ||
|
|
||
| | Z-pointer Address | Atmega328pb | Atmega328p | | ||
| | :-------: | :------: | :------:| | ||
| | 0x000E | Byte 0 | Byte 0 | | ||
| | 0x000F | Byte 1 | Byte 1 | | ||
| | 0x0010 | Byte 2 | Byte 2 | | ||
| | 0x0011 | Byte 3 | Byte 3 | | ||
| | 0x0012 | Byte 4 | Byte 4 | | ||
| | 0x0013 | Byte 5 | Byte 5 | | ||
| | 0x0014 | Byte 6 | - | | ||
| | 0x0015 | Byte 7 | Byte 6 | | ||
| | 0x0016 | Byte 8 | Byte 7 | | ||
| | 0x0017 | Byte 9 | Byte 8 | | ||

| ## Tested Microcontroller | ||

|
||
| * Atmega328pb - 10 bytes | ||
| * Atmega328p - 9 bytes | ||
| * Atmega2560 - 9 bytes | ||

| # Atmel SAM ARM Microcontroller | ||
|
|
||
| Atmel SAM3X8E is used in Arduino Due. | ||
|
|
||
| The Unique Identifier is located in the first 128 bits of the Flash memory mapping. So, at the address 0x400000-0x400003. | ||
|
|
||
| "Each device integrates its own 128-bit unique identifier. These bits are factory configured and cannot be changed by the user. The ERASE pin has no effect on the unique identifier." [Datasheet Section 7.2.3.7](http://ww1.microchip.com/downloads/en/devicedoc/atmel-11057-32-bit-cortex-m3-microcontroller-sam3x-sam3a_datasheet.pdf) | ||
|
|
||
| ## Tested Microcontroller | ||
|
|
||
| * Atmel SAM3X8E ARM Cortex-M3 - 16 bytes | ||
|
|
||
| # Atmel SAMD ARM Microcontroller | ||
|
|
||
| Atmel SAMD21 is used in Arduino Zero / Arduino M0. | ||
|
|
||
| Each device has a unique 128-bit serial number which is a concatenation of four 32-bit words contained at the following addresses: | ||
|
|
||
| * Word 0: 0x0080A00C | ||
| * Word 1: 0x0080A040 | ||
| * Word 2: 0x0080A044 | ||
| * Word 3: 0x0080A048 | ||
|
|
||
| The uniqueness of the serial number is guaranteed only when using all 128 bits. [Datasheet Section 9.3.3](https://cdn.sparkfun.com/datasheets/Dev/Arduino/Boards/Atmel-42181-SAM-D21_Datasheet.pdf) | ||

| ## Tested Microcontroller | ||
|
|
||
| * Atmel SAMD21 ARM Cortex-M0 - 16 bytes | ||
|
|
||
| # STM32 Microcontroller | ||
|
|
||
| STM32 32-bit Arm Cortex MCUs has a unique 96-bit serial number which is a concatenation of three 32-bit words, the address is different depending on the microcontroller. | ||
|
|
||
| The [Arduino Core STM32](https://github.com/stm32duino/Arduino_Core_STM32) has the functions HAL_GetUIDw0(), HAL_GetUIDw1() and HAL_GetUIDw2() for 96-bit UID. | ||
|
|
||
| ## Tested Microcontroller | ||
|
|
||
| * STM32F103C8 (BluePill Board) - 12 bytes | ||
| * STM32L073RZ (Nucleo L073RZ) - 12 bytes | ||

| # Espressif ESP Microcontroller | ||
|
|
||
| ESP microcontroller has basically two versions, ESP8266 and ESP32, each one has a specific function to request the chip id. <br/> | ||
|
|
||
| * ESP8266 - ESP.getChipId() - 4 bytes | ||
| * ESP32 - ESP.getEfuseMac() - 6 bytes | ||
|
|
||
| | UniqueID | ESP8266 | ESP32 | | ||
| | :-------: | :------: | :------:| | ||
| | Byte 0| Byte 0 | Byte 5 | | ||
| | Byte 1| Byte 1 | Byte 4 | | ||
| | Byte 2| Byte 2 | Byte 3 | | ||
| | Byte 3| Byte 3 | Byte 2 | | ||
| | Byte 4| - | Byte 1 | | ||
| | Byte 5| - | Byte 0 | | ||
|
|
||
| To make the variable UniqueID8 to work propably the library uses the default bytes to 0x00. <br/> | ||
