Load condition is C L = 50 pF. t LZ (max) defines the time at which the outputs achieves the low impedance state. t HZ (max) defines the time at which the outputs achieves the high impedance state. t CES defines CKE setup time to CK rising edge except power down exit command. Test Conditions • Input and output timing reference levels: 1.5 V • Input waveform and output load: See following figures 2.4 V input 0.4 V DQ 2.0 V 0.8 V CL t T tT Data Sheet E0084H10 19 HB52D328DC-B Relationship Between Frequency and Minimum Latency HB52D328DC Parameter -A6B/B6B/A6BL/B6BL Frequency (MHz) 100 PC100 Symbol Symbol 10 Notes Active command to column command (same bank) I RCD 2 1 Active command to active command (same bank) I RC 7 = [IRAS + IRP] 1 Active command to precharge command (same bank) I RAS 5 1 Precharge command to active command (same bank) I RP 2 1 Write recovery or data-in to precharge command (same bank) I DPL 2 1 Active command to active command (different bank) I RRD 2 1 Self refresh exit time I SREX Tsrx 1 2 Last data in to active command (Auto precharge, same bank) I APW Tdal 4 = [IDPL + IRP] Self refresh exit to command input I SEC 7 = [IRC] 3 Precharge command to high impedance (CE latency = 2) I HZP Troh 2 I HZP Troh 3 tCK (ns) (CE latency = 3) Last data out to active command (auto precharge) (same bank) Last data out to precharge (early precharge) (CE latency = 2) (CE latency = 3) Tdpl I APR 1 I EP –1 I EP –2 Column command to column command I CCD Tccd 1 Write command to data in latency I WCD Tdwd 0 DQMB to data in I DID Tdqm 0 DQMB to data out I DOD Tdqz 2 CKE to CK disable I CLE Tcke 1 Register set to active command I RSA Tmrd 1 S to command disable I CDD 0 Power down exit to command input I PEC 1 Data Sheet E0084H10 20 HB52D328DC-B Notes: 1.

Except [DSEL] and [NOP] Data Sheet E0084H10 21 HB52D328DC-B Pin Functions CK0/CK1 (input pin): CK is the master clock input to this pin. The other input signals are referred at CK rising edge. S0/S1 (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 DRAM modules, 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 AY8) is determined by A0 to A8 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, both 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 is a bank select signal (BA). The memory array is divided into bank0, bank1, bank2 and bank3. If BA0 is Low and BA1 is Low, bank0 is selected. If BA0 is High and BA1 is Low, bank1 is selected. If BA0 is Low and BA1 is High, bank2 is selected. If BA0 is High and BA1 is HIgh, bank3 is selected. CKE0, CKE1 (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 powerdown mode, clock suspend mode and self refresh mode. 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 (The latency of DQMB during reading is 2 clocks). 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 (The latency of DQMB during writing is 0 clock). DQ0 to DQ63 (DQ 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.
