DDR2 SDRAM SO-DIMM
Hynix HYMP112S64MP8 series is unbuffered 200-pin double data rate 2 Synchronous DRAM Small Outline Dual In-Line Memory Mod-
ules (DIMMs) which are organized as 128Mx64 high-speed memory arrays. Hynix HYMP112S64MP8 series consists of eight 128Mx8
DDR2 SDRAMs in 63 ball FBGA Dual Die Pacakge(DDP)s. Hynix HYMP112S64MP8 series provide a high performance 8-byte interface
in 67.60mm X 30.00mm form factor of industry standard. It is suitable for easy interchange and addition.
Hynix HYMP512S64MP8 series is designed for high speed and offers fully synchronous operations referenced to both rising and falling
edges of differential clock inputs. While all addresses and control inputs are latched on the rising edges of the clock, Data, Data
strobes and Write data masks inputs are sampled on both rising and falling edges of it. The data paths are internally pipelined and 4-
bit prefetched to achieve very high bandwidth. All input and output voltage levels are compatible with SSTL_1.8. High speed frequen-
cies, programmable latencies and burst lengths allow variety of device operation in high performance memory system.
Hynix HYMP512S64MP8 series incorporates SPD(serial presence detect). Serial presence detect function is implemented via a serial
2,048-bit EEPROM. The first 128 bytes of serial PD data are programmed by Hynix to identify DIMM type, capacity and other the
information of DIMM and the last 128 bytes are available to the customer.
