# SPD5118\-Y1B000NCG8 (Component)

## Description

DDR5 SPD Hub EEPROM with Integrated Temperature Sensor – Serial Presence Detect \(SPD\) hub device for DDR5 DIMMs and memory modules, combining 1024\-byte non\-volatile EEPROM, I²C/I³C hub functionality, and an integrated digital temperature sensor for server, desktop, workstation, and embedded memory applications\. Operates from a 1\.8 V supply with support for I²C \(up to 1 MHz\) and I³C Basic \(up to 12\.5 MHz\) interfaces, providing 16 programmable 64\-byte EEPROM blocks with independent write protection\. Features hub functionality with address translation, Packet Error Checking \(PEC\), parity error checking, In\-Band Interrupt \(IBI\) support, programmable device addressing, and an integrated temperature sensor with ±0\.5°C accuracy and 0\.25°C resolution for thermal monitoring of DDR5 memory modules\. Designed for client and server DDR5 memory systems, it operates over a 0°C to \+70°C commercial temperature range and is housed in an 8\-pin DFN \(2\.0 × 3\.0 mm\) package\.
