ConnectCore ? f or ? i .M X 5 1 ?
Memory
DDR2 SDRAM Memory
The ConnectCore for i.MX51 module provides up to 512 MBytes of DDR2-400 SDRAM memory.
The module can support up to four 16-bit, 128Mbit, DDR2-400 chips, configured as two banks
of 32-bits of 128Mbits DDR2-400 memory.
NAND Flash Memory
The ConnectCore for i.MX51 module provides 512Mbytes of NAND-Flash memory. On the
module a 512MByte, 2Kbyte page, NAND-Flash chip is used.
Options for other densities NAND Flash devices are available depending on the module
variant.
