SPD HUB for DDR5 Memory Modules
Jump to Page Section:
Overview
Description
The SPD5 Hub family (SPD5118) device is a DDR5 Serial Presence Detect (SPD) EPPROM with Hub function (SPD5 Hub) and integrated Temperature Sensor (optional) as used for memory module applications. The Hub feature allows isolation of a local bus from a master host bus. The SPD5 Hub family device contains 1024 bytes of non-volatile memory (EEPROM) arranged as 16 blocks of 64 bytes per block. Each block may optionally be write protected via software command.
Features
- Two wire programmable I²C or I3C bus serial interface
- Single device load on the Host bus
- Up to 12.5MHz transfer rate
- 1.8V power supply input
- 1.0V VLDO output at VIO pin; optionally can take 1.0V input power supply on VIO pin
- Supports 1.0V, 1.1V and 1.2V Push-Pull IO levels
- Supports 1.0V, 1.1V, 1.2V, 1.8V, 2.5V and 3.3V Open Drain IO levels
- 16 blocks of non-volatile memory (NVM), 64 bytes per block
- Hub function with 3 address bit translation
- Integrated Temperature Sensor; 0.5°C accuracy with 0.25°C resolution
- Packet Error Check (PEC) function
- Parity Error Check function
- Up to 8 unique addressing
- Programmable I2C, I3C Bus Addressing Scheme
- In Band Interrupt (IBI)
- Write protection for each block of NVM
- 9-pin thermally enhanced DFN package
- Temperature: Industrial Range of -40°C to 125°C
