SE98ATP,547

SE98ATP,547 is a DDR memory module temp sensor. It is typically mounted on a Dual In-Line Memory Module (DIMM) measuring the DRAM temperature in accordance with the new JEDEC (JC-42.4) mobile platform memory module thermal sensor component specification. It does not include the 2 k SPD and is designed for custom DIMM where larger SPD is required. The temp sensor (TS) consists of an analog-to-digital converter (ADC) that monitors and updates its own temperature readings 8 times per second, converts the reading to a digital data, and latches them into the data temperature registers. User-programmable registers, such as shutdown or low-power modes and the specification of temperature event and critical output boundaries, provide flexibility for DIMM temperature-sensing applications. Application includes DDR2 and DDR3 memory modules, laptops, personal computers and servers, enterprise networking, hard disk drives and other PC peripherals.
