Mobile DDR SDRAM 128Mbit (4M x 32bit)
H5MS1222EFP Series
The Hynix H5MS1222EFP series has the special Low Power function of Auto TCSR (Temperature Compensated Self
Refresh) to reduce self refresh current consumption. Since an internal temperature sensor is implemented, it enables
to automatically adjust refresh rate according to temperature without external EMRS command.
Deep Power Down Mode is an additional operating mode for Low Power DDR SDRAM (Mobile DDR SDRAM). This mode
can achieve maximum power reduction by removing power to the memory array within Low Power DDR SDRAM
(Mobile DDR SDRAM). By using this feature, the system can cut off almost all DRAM power without adding the cost of
a power switch and giving up mother-board power-line layout flexibility.
All inputs are LVCMOS compatible. Devices will have a VDD and VDDQ supply of 1.8V (nominal).
The Hynix H5MS1222EFP series is available in the following package:
- 90Ball FBGA [size: 8mm x 13mm, t=1.0mm max]
