DATASHEET
TPS54286PWPR 描述
The Hynix HYM71V16C755AT8 Series are 16Mx72bits ECC Synchronous DRAM Modules. The modules are composed of nine 16Mx8bits 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 two 0.0022uF decoupling capacitors per each SDRAM are mounted on the PCB.
TPS54286PWPR 特点
Each TPS54286PWPR contains a unique 64Cbit code (see Figure 5) stored in ROM. The least significant 8 bits of the ROM code contain the TPS54286PWPRs 1Cwire family code: 28h. The next 48 bits contain a unique serial number. The most significant 8 bits contain a cyclic redundancy check (CRC) byte that is calculated from the first 56 bits of the ROM code. A detailed explanation of the CRC bits is provided in the CRC GENERATION section. The 64Cbit ROM code and associated ROM function control logic allow the TPS54286PWPR to operate as a 1Cwire device using the protocol detailed in the 1-WIRE BUS SYSTEM section of this datasheet.
