The SoDIMM use serial presence detects (SPD) implemented via serial EEPROM using the two-pin-I C protocol.
This Swissbit module family is industry standard 200-pin 8-byte Double Date rate synchronous SDRAM Small
Outline Dual-In-line Memory Modules (SoDIMMs), which are organized as x64 high speed memory arrays designed
for use in non-parity applications. SoDIMMs are assembled in FBGA Technology. The passive devices and the
EEPROM are SMD components.

The first 128 bytes are utilized by the SoDIMM manufacturer and the second 128 bytes are available to the end
user.
All Swissbit SoDIMMs provide a high performance, flexible 8-byte interface in a 67.60mm long footprint.
All modules of the extended temperature grade have seen special tests during the manufacturing process to
ensure proper operation according to the field of operation as stated in the environmental conditions.
