Pin Functions
CLK (input pin): CLK is the master clock input pin. The other input signals are referred at CLK rising edge. CS (input pin): When CS is Low, the command input cycle becomes valid. When CS is High, all inputs are ignored. However, internal operations (bank active, burst operations, etc.) are held. RAS, CAS, and WE (input pins): These pins define operation commands (read, write, etc.) depending on the combination of their voltage levels. For details, refer to the command operation section. DSF (input pin): DSF is a part of inputs of graphic commands of the HM5283206. If DSF is LOW, the HM5283206 operates as standard synchronous DRAM. A0 to A8 (input pins): Row address (AX0 to AX8) is determined by A0 to A8 pins at the CLK rising edge when a bank active command is input. Column address (AY0 to AY7) is determined by levels on A0 to A7 pins at the CLK rising edge when a read or write command is input. A8 determins precharge mode. When A8 is low, only the bank selected by A9 (BS) is precharged by a precharge command. When A8 is high, both banks are precharged by a precharge command. A9 (input pin): A9 is the bank select signal (BS). The memory array of the HM5283206 is divided into the bank 0 and the bank 1, both contain 512 row x 256 column x 32 bits. If A9 is Low, the bank 0 is selected, and if A9 is High, the bank 1 is selected. CKE (input pin): By referring low level on CKE pin, HM5283206 determines to go into clock suspend modes or power down modes. In self refresh mode, low level on this pin is also referred to turn on refresh process. DQM0, DQM1, DQM2 and DQM3 (input pins): DQM0 applies to DQ0 to DQ7. DQM1 applies to DQ8 to DQ15. DQM2 applies to DQ16 to DQ23. DQM3 applies to DQ24 to DQ31. In read mode, referring high level on DQM pins, HM5283206 floats related DQ pins. In write mode, referring high level on DQM pins, HM5283206 ignores input data through related DQ pins. DQ0 to DQ31 (input/output): These are the data line for the HM5283206. VDD and VDDQ (power supply pins): 3.3 V is applied. (VDD is for the internal circuit and V DD Q is power supply pin for DQ output buffer.) VSS and VSS Q (power supply pins): Ground is connected. (VSS is for the internal circuit and VSSQ is for DQ output buffer.)

Commands Operation
Commands Explanation Every operations of HM5283206 are executed by input commands. A command is input, at the rising edge of CLK, by setting the levels on CS, RAS, CAS, WE, A8 (auto precharge) and DSF pins, HIGH (VIH) or LOW (V IL ). Note: The setup and hold condition should be obeyed when command, address or data is input. Setup and Hold Condition of Command, Address and Data Input

Graphic Commands Special mode register set command (SMRS): If each banks is in idle state or activated, at the CLK rising edge, by setting CS, RAS, CAS, WE; LOW, DSF; HIGH, an internal register (the special mode register; SMRS) are set. The data through address pins, at the cycle when this command is input, are stored in the special mode register. A0 to A4: reserved. should be LOW when SMRS is issued. A5: determines whether loading mask data or not when SMRS is issued. A6: determines whether loading color data or not when SMRS is issued. A7 to A9: reserved. should be set LOW when SMRS is issued. In case A5 bit of the mode register = HIGH, the data through DQ pins, at the cycle this command is issued, are stored in the MASK register (32 bits). If write per bit function is available*, and DQi (i = 0,..,31)bit of the MASK register = LOW, DQi data path to memory array is masked. In case A6 bit of the mode register HIGH, the data through DQ pins, at the cycle when this command is issued, are stored in the COLOR register (32 bits). This specific data is written to 8 columns in one clock cycle by block write command. Note: When bank active command is issued and DSF set to LOW, write per bit function is enabled.

Read/Write Operations Bank active: A read/write operation begins with a bank active command (ACTV or ACTVM). The bank active command determines a bank (A9) and a row address (AX0 to AX8). For the bank and the row, a read/write command can be applied. An interval not less than tRCD, after an ACTV/ ACTVM command to a read/write command, is required. Read operation: Burst length (BL), CAS latency (CL) and burst type (BT) of the mode register are referred when read command is executed. Burst length (BL) determines the length of a sequential data by a single read command, which can be set to 1, 2, 4, 8 or 256 (full-page). Starting address of a burst data is defined by column address (AY0 to AY7) and bank select address (A9) loaded through A0 to A9 in the cycle when the read command is issued. CAS latency (CL) determines the delay of data output after read command input. When burst length is 1, 2, 4 or 8, DQ buffers automatically become High-Z at the next cycle after completion of burst read. When burst length is full-page (256), data are repeatedly output until a burst stop command, a read/write command or a precharge command is input.

Burst operation (on read or write): One burst data output/input by one read/write command are included in a column block determined by A1 to A7 in case BL (Burst Length) = 2, by A2 to A7 in case BL = 4 and by A3 to A7 in case BL = 8. Burst type (BT) determines the order how data of the column block are output/input. There are two burst types, sequential (wrap around) or interleave. The order of the burst data depends also on the start cloumn location of the burst data. See tables below for details.

Write operation: OPCODE (A9, A8) of the mode register is referred when a write command is executed as well as BL (Burst Length) and BT (Burst Type). CL (CAS Latency) is ignored and CL is fixed to 0 for write operation, that is, write data input starts on the same cycle when the write command is issued. Burst write: Before executing a burst write operation, OPCODE (A9, A8) should be set to (0, 0). Burst length (BL) determines the length of a sequential data by the burst write command, which can be set to 1, 2, 4, 8 or 256 (full-page). Starting address of a burst data is defined by column address (AY0 to AY7) and bank select address (A9) loaded through A0 to A9 in the cycle when the burst write command is issued.

Write per bit: To use write per bit function, 1. Set mask data in advance, which define DQ paths to be masked, to the MASK register by SMRS command. An interval not less than tRSC after a SMRS command to an ACTVM command is necessary. 2. Use ACTVM command to activate the bank for which write per bit operation is performed. An interval not less than tRCD, after an ACTVM command to a write or a block write command, is necessary. 3. Execute a write or a block write command. In this write operation, DQ paths defined by mask register are masked to preserve the previous data. (See the example below) Special Mode Register Set (Load Mask) in Idle State and Write Per Bit

Block write: Before executing a block write command, a color data (32 bit) should be set in advance, which is allowed to be written in 8 columns at one write cycle, to the color register by SMRS command. An interval not less than tRSC after a SMRS command to an ACTVM command is necessary. If a SMRS command is executed in active state to set the color register, an interval not less than tSBW is required before executing a block write command after the SMRS command. If a block write command is applied to the bank which is activated by ACTVM command, write per bit function is also available. DQ inputs at the cycle, when a block write command is executed, are reffered to mask the specific columns. See the example below. Special Mode Register Set (Load Mask) in Idle State and Block Write

Full Page Burst Stop Burst stop command during burst read: Burst stop command is used to stop data output during a full-page burst read. This command sets the output buffer to High-Z and stops the full-page burst read. The timing, from command input to the last data, depends on CAS latency. BST command is legitimate only in case full page burst mode, and is illegal in case burst length 1, 2, 4 or 8.

DQM Control The DQM i (i=0, 1, 2, 3) controls the ith byte of DQ data. DQM control operation for read and for write are different in terms of latency. Reading: When data are read, output buffer can be controlled by DQMi. By setting DQMi to LOW, the corresponding DQ output buffers become active. By setting DQMi to HIGH, the corresponding DQ output buffers are made floated so that the ith byte of data are not driven out. The latency of DQM operation for read operation is 2.
CLK DQM DQout 0 1 3 IDOD= 2 Latency
Writing: Input data can be controlled by DQMi. While DQMi is LOW, data is driven into the HM5283206. By setting DQMi to HIGH, corresponding ith byte of DQ input data are kept from being written to the HM5283206 and the previous data are protected. The latency of DQM control operation is 0.

Refresh Auto Refresh: All the banks must be precharged before executing an auto-refresh command. Auto refresh command increments the internal counter every time when it is executed. This command also determines the row to be refreshed. Therefore external address specification is not necessary. Refresh cycle is 1024 cycles/16ms. (1024 cycles are required to refresh all the row addresses.) All output buffers become High-Z after auto-refresh start. No prechrage commands are necessary after this operation. Self Refresh: When issuing a self refresh command, by changing the level on CKE pin from HIGH to LOW simultaneously, a self refresh operation starts and is kept while CKE is LOW. During the self-refresh operation, all data schedule to be refreshed internally. This operation managed by an internal refresh timer. After exiting from the self refresh, since the last row refreshed cannot be determined, auto-refresh commands should immediately be performed for all addresses. Change the level on the CKE pin from LOW to HIGH to exit from Self refresh mode. Others Power Down Mode: Power down mode is a state in which all input buffers except the CKE input buffer are made inactive and clock signal is masked to cut power dissipation. To enter into power down mode, CKE should be set to low. Power down mode is kept as long as CKE is low. Change the level on the CKE pin from LOW to HIGH to exit from Power down mode. In this mode, internal refresh is not performed. Clock Suspend: The HM5283206 enters into clock suspend mode from active mode by setting CKE to low. There are several types of clock suspend mode depends on the state when CKE level is changed from HIGH to LOW. ACTIVE clock suspend: If CKE-transition (1 to 0) happens during a bank active state, the bank active status is kept. Any input signals are ignored during this mode. READ and READ A suspend: If CKE transition (1 to 0) happens during a read operation, the read operation is kept or DQ output data is driven out until completion. Any input signals are ignored during this mode. WRITE (BLOCK WRITE) and WRITE A (BLOCK WRITE A) suspend: If CKE-transition (1 to 0) happens during a write operation, though any input signals include DQ input data ignored, the write operation is kept until completion. Any input signals are ignored during this mode. Change the level on the CKE pin from LOW to HIGH to exit from Clock suspend mode.

Notes: 1. AC measurement assumes t T = 1 ns. Reference level for timing of input signals is 1.4 V. Test load (A) is used with CL = 30 pF in general except fpr the measurement of access time (note2) and tHZ (note3). 2. Access time is measured at 1.4 V. Test load (B) is used with current source. 3. t HZ (max) defines the time at which the outputs achieves 200 mV. Test load (A) is used with CL = 5 pF and with current source. 4. When Active Suspend Exit, Power Down Exit or Self Refresh Exit is executed. CKE should be kept "H" more than 1 cycle from these Exit cycles.
