HY5W2A2(L/S)F / HY57W2A3220(L/S)T
HY5W22F / HY57W283220T
4Banks x 1M x 32bits Synchronous DRAM
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 HY5W2A2F series is a 134,217,728-bit CMOS Synchronous DRAM, ideally suited for the memory applica-
tions which require wide data I/O and high bandwidth. HY5W2A2F series is organized as 4banks of 1,048,576x32.
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 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
command 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 lay-
out flexibility.
