DESCRIPTION
The Hynix Low Power SDRAM is suited for non-PC application which use the batteries such as PDAs,
2.5G and 3G cellular phones with internet access and multimedia capabilities, mini-notebook, handheld
PCs.
The Hynix HY5W2A6CF is a 134,217,728bit CMOS Synchronous Dynamic Random Access Memory. It
is organized as 4banks of 2,097,152x16.
The Low Power SDRAM provides for programmable options including CAS latency of 1, 2, or 3, READ
or WRITE burst length of 1, 2, 4, 8, or full page, and the burst count sequence(sequential or interleave).
And the Low Power SDRAM also provides for special programmable options including Partial Array Self
Refresh of a quarter bank, a half bank, 1bank, 2banks, or all banks, Temperature Compensated Self
Refresh of 15, 45, 70, or 85 degrees C. A burst of Read or Write cycles in progress can be terminated
by a burst terminate command or can be interrupted and replaced by a new burst Read or Write com-
mand on any cycle(This pipelined design is not restricted by a 2N rule).
Deep Power Down Mode is a additional operating mode for Low Power SDRAM. This mode can achieve
maximum power reduction by removing power to the memory array within each SDRAM. By using this
feature, the system can cut off alomost all DRAM power without adding the cost of a power switch and
giving up mother-board power-line layout flexibility.
