The HB52F649E1 belongs to 8-byte DIMM (Dual In-line Memory Module) family, and has been developed as an optimized main memory solution for 8-byte processor applications. The HB52F649E1 is a 64M × 72 × 1-bank Synchronous Dynamic RAM Registered Module, mounted 18 pieces of 256-Mbit SDRAM (HM5225405BTT) sealed in TSOP package, 1 piece of PLL clock driver, 3 pieces of register driver and 1 piece of serial EEPROM (2-kbit) for Presence Detect (PD). An outline of the HB52F649E1 is 168-pin socket type package (dual lead out). Therefore, the HB52F649E1 makes high density mounting possible without surface mount technology. The HB52F649E1 provides common data inputs and outputs. Decoupling capacitors are mounted beside each TSOP on the module board.

Pin Functions

CK0 to CK3 (input pin): CK is the master clock input to this pin. The other input signals are referred at CK
rising edge.
S0, S2 (input pin): When S is Low, the command input cycle becomes valid. When S is High, all inputs are ignored. However, internal operations (bank active, burst operations, etc.) are held.
RE, CE and W (input pins): Although these pin names are the same as those of conventional DRAMs, they function in a different way. These pins define operation commands (read, write, etc.) depending on the combination of their voltage levels. For details, refer to the command operation section.
A0 to A12 (input pins): Row address (AX0 to AX12) is determined by A0 to A12 level at the bank active command cycle CK rising edge. Column address (AY0 to AY9, AY11) is determined by A0 to A9, A11 level at the read or write command cycle CK rising edge. And this column address becomes burst access start address. A10 defines the precharge mode. When A10 = High at the precharge command cycle, all banks are precharged. But when A10 = Low at the precharge command cycle, only the bank that is selected by BA0/BA1 (BA) is precharged.
BA0/BA1 (input pin): BA0/BA1 are bank select signal (BA). The memory array is divided into bank 0, bank 1, bank 2 and bank 3. If BA1 is Low and BA0 is Low, bank 0 is selected. If BA1 is High and BA0 is Low, bank 1 is selected. If BA1 is Low and BA0 is High, bank 2 is selected. If BA1 is High and BA0 is High, bank 3 is selected.
CKE0 (input pin): This pin determines whether or not the next CK is valid. If CKE is High, the next CK rising edge is valid. If CKE is Low, the next CK rising edge is invalid. This pin is used for power-down and clock suspend modes.
DQMB0 to DQMB7 (input pins): Read operation: If DQMB is High, the output buffer becomes High-Z. If the DQMB is Low, the output buffer becomes Low-Z.
Write operation: If DQMB is High, the previous data is held (the new data is not written). If DQMB is Low, the data is written.
DQ0 to DQ63, CB0 to CB7 (input/output pins): Data is input to and output from these pins.
VCC (power supply pins): 3.3 V is applied.
VSS (power supply pins): Ground is connected.
