HSD32M64D16R
Synchronous DRAM Module 256Mbyte (32Mx64bit), DIMM with based on 16Mx8, 4Banks, 4K Ref., 3.3V GENERAL DESCRIPTION
The HSD32M64D16R is a 32M x 64 bit Synchronous Dynamic RAM high-density memory module. The module consists of sixteen CMOS 16M x 8 bit with 4banks Synchronous DRAMs in TSOP-II 400mil packages and 2K EEPROM in 8-pin TSSOP package on a 168-pin glass-epoxy. One 0.22uF and two 0.0022uF decoupling capacitors are mounted on the printed circuit board in parallel for each SDRAM. The HSD32M72D18AR is a DIMM (Dual in line Memory Module) and is intended for mounting into 168-pin edge connector sockets. Synchronous design allows precise cycle control with the use of system clock. I/O transactions are possible on every clock cycle. Range of operating frequencies, programmable latencies allows the same device to be useful for a variety of high bandwidth, high performance memory system applications All module components may be powered from a single 3.3V DC power supply and all inputs and outputs are LVTTL-compatible.

PIN FUNCTION DESCRIPTION
Pin CLK /CE Name System clock Chip enable Input Function
HSD32M64D16R
Active on the positive going edge to sample all inputs. Disables or enables device operation by masking or enabling all inputs except CLK, CKE and DQM
CKE
Clock enable
Masks system clock to freeze operation from the next clock cycle. CKE should be enabled at least one cycle prior to new command. Disable input buffers for power down in standby. CKE should be enabled 1CLK+tss prior to valid command.
A0 ~ A11
Address
Row/column addresses are multiplexed on the same pins. Row address : RA0 ~ RA11, Column address : CA0 ~ CA9
BA0 ~ BA1
Bank select address
Selects bank to be activated during row address latch time. Selects bank for read/write during column address latch time.
/RAS
Row address strobe
Latches row addresses on the positive going edge of the CLK with /RAS low. Enables row access & precharge.
/CAS
Column strobe
address
Latches column addresses on the positive going edge of the CLK with /CAS low. Enables column access.
/WE
Write
enable
Enables write operation and row precharge. Latches data in starting from /CAS, /WE active.
DQM0 ~ 7
Data mask
input/output
Makes data output Hi-Z, tsHZ after the clock and masks the output. Blocks data input when DQM active. (Byte masking) The device operates in the transparent mode when REGE is low. When REGE is high, the device operates in the registered mode. In registered mode, the Address and control inputs are latched if CLK is held at a high or low logic level. The inputs are strobed in the latch/flip-flop on the riging edge of CLK. REGE is tied to VDD through 10K ohm register on PCB. So if REGE of module is floating, this module will be operated as registerd mode.
REGE
Register enable
DQ0 ~ 63 WP
Data input/output Write Protection
Data inputs/outputs are multiplexed on the same pins. WP pin is connected to Vcc. When WP is "high", EEPROM Programming will be inhibited and the entire memory will be write-protected.
VDD/VSS
Power supply/ground
Power and ground for the input buffers and the core logic.

Notes : 1. The minimum number of clock cycles is determined by dividing the minimum time required with clock cycle time and then rounding off to the next higher integer. 2. Minimum delay is required to complete write. 3. All parts allow every cycle column address change. 4. In case of row precharge interrupt, auto precharge and read burst stop. .5. For -1H/1L, tRDL=1CLK and tDAL=1CLK+20ns is also supported . ( recommend : tRDL=2CLK and tDAL=2CLK + 20ns.)

Notes : 1. Parameters depend on programmed CAS latency. 2. If clock rising time is longer than 1ns, (tr/2-0.5)ns should be added to the parameter. 3. Assumed input rise and fall time (tr & tf) = 1ns. If tr & tf is longer than 1ns, transient time compensation should be considered i.e., [(tr + tf)/2-1]ns should be added to the parameter.

(V=Valid, X=Don't care, H=Logic high, L=Logic low) Notes : 1. OP Code : Operand code A0 ~ A11 & BA0 ~ BA1 : Program keys. (@ MRS) 2. MRS can be issued only at all banks precharge state. A new command can be issued after 2 CLK cycles of MRS. 3. Auto refresh functions are as same as CBR refresh of DRAM. The automatical precharge without row precharge command is meant by "Auto". Auto/self refresh can be issued only at all banks precharge state. 4. BA0 ~ BA1 : Bank select addresses. If both BA0 and BA1 are "Low" at read, write, row active and precharge, bank A is selected. If both BA0 is "Low" and BA1 is "High" at read, write, row active and precharge, bank B is selected. If both BA0 is "High" and BA1 is "Low" at read, write, row active and precharge, bank C is selected. If both BA0 and BA1 are "High" at read, write, row active and precharge, bank D is selected. If A10/AP is "High" at row precharge, BA0 and BA1 is ignored and all banks are selected. 5. During burst read or write with auto precharge, new read/write command can not be issued. Another bank read/write command can be issued after the end of burst. New row active of the associated bank can be issued at t RP after the end of burst. 6. Burst stop command is valid at every burst length. 7. DQM sampled at positive going edge of a CLK and masks the data-in at the very CLK (Write DQM latency is 0), but makes Hi-Z state the data-out of 2 CLK cycles after. (Read DQM latency is 2)

td, tr = Delay of register (74LVC162835) Notes : 1.In case of module timing, command cycles 1CLK with respect to external input timing at the address and input signal because of the buffering in register (74LVC162835). Therefore, Input/Output signals of read/write function should be issued 1CLK earlier as compared to Unbuffered DIMMs. 2. DIN is to be issued 1 clock after write command in external timing because D IN is issued directly to module.
