Description
The INFINEON HYS64T[3200/6402]0[H/K/L]M–
[3.7/5]–A module family are low profile Unbuffered
Micro-DIMM modules “MDIMMs” with 30,0 mm height
based on DDR2 technology. DIMMs are available as
32M × 64 and 64M × 64 organisation and density,
intended for mounting into 214-pin mezzanine
connector sockets.
The memory array is designed with 512Mb Double-
Data-Rate-Two (DDR2) Synchronous DRAMs.
Decoupling capacitors are mounted on the PCB board.
The DIMMs feature serial presence detect based on a
serial E²PROM device using the 2-pin I²C protocol. The
first 128 bytes are programmed with configuration data
and are write protected; the second 128 bytes are
available to the customer.
