260Pin DDR4 2400 Industrial ECC SO-DIMM
16GB Based on 1Gx8
TS16D42AR00SNSI
Description
DDR4 Industrial ECC SO-DIMMs are high-speed low
power memory modules that use 1Gx8bits DDR4 SDRAM
in FBGA package and a 4K-bit serial EEPROM on a
260-pin printed circuit board. DDR4 Industrial ECC
SO-DIMMs are dual In-Line memory modules and are
intended for mounting into 260-pin edge connector
sockets.
The synchronous design allows precise cycle control with
the use of system clock. Data I/O transactions are
possible on both edges of DQS. The large range of
operation frequencies and programmable latencies allow
the same device to be useful for a variety of high
bandwidth and high performance memory system
applications.
