| The HYM72V32736B(L)T8 Series are 32Mx72bits ECC Synchronous DRAM Modules. The modules are composed of nine 32Mx8bits CMOS Synchronous DRAMs in 400mil 54pin TSOP-II package, one 2Kbit EEPROM in 8pin TSSOP package on a 168pin glass-epoxy printed circuit board. One 0.22uF and one 0.0022uF decoupling capacitors per each SDRAM are mounted on the PCB. |

| The data record starts with a length byte (0AH) and the 4-byte UniqueWare Project ID 00001129H. The next 6 bytes contain the 48-bit node address which consists of an incrementing 24-bit extension identifier and the IEEE-assigned 24-bit company ID value 006035H. A 16-bit CRC ends the data record. The remaining bytes of the 32-byte memory page remain unprogrammed. Neither the 24-bit extension identifier nor the 24-bit company ID are related to the 64-bit ROM registration number. The ROM registration number is used to provide a unique address to access the CDRH6D285R0NCSMT-2 when multidropped on a 1-Wire bus. |
