PRELIMINARY DATA SHEET
256MB Unbuffered SDRAM Micro DIMM
HB52RF328GB-B (32M words × 64 bits, 1 bank)
HB52RD328GB-B (32M words × 64 bits, 1 bank)
Description
Features
EO
L
The HB52RF328GB and HB52RD328GB are a 32M ×
64 × 1 banks Synchronous Dynamic RAM Micro Dual
In-line Memory Module (Micro DIMM), mounted 8
pieces of 256M bits SDRAM (HM522805BTB/BLTB)
sealed in TCP package and 1 piece of serial EEPROM
(2k bits EEPROM) for Presence Detect (PD). An
outline of the products is 144-pin Zig Zag Dual tabs
socket type compact and thin package. Therefore,
they make high density mounting possible without
surface mount technology. They provide common data
inputs and outputs.
Decoupling capacitors are
mounted beside TCP on the module board.
Note: Do not push the cover or drop the modules in
order to protect from mechanical defects, which
would be electrical defects.

Notes: 1. All serial PD data are not protected. 0: Serial data, “driven Low”, 1: Serial data, “driven High”. These
SPD are based on Rev.1.2B specification.
2. Byte72 is manufacturing location code. (ex: In case of Japan, byte72 is 4AH. 4AH shows “J” on ASCII
code.)
3. Bytes 95 through 98 are assembly serial number.
4. All bits of 99 through 125 are not defined (“1” or “0”).

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 (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.
EO
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) is determined by A0 to A9 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 Low and BA1 is High, bank1 is
selected. If BA0 is High and BA1 is Low, bank2 is selected. If BA0 is High and BA1 is High, bank3 is selected.
L
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 mode, clock suspend
mode and self refresh mode.
u
od
Pr
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): 3.3V is applied.
VSS (power supply pins): Ground is connected.

CAUTION FOR HANDLING MEMORY MODULES
When handling or inserting memory modules, be sure not to touch any components on the modules, such as
the memory IC, chip capacitors and chip resistors. It is necessary to avoid undue mechanical stress on these
components to prevent damaging them.
When re-packing memory modules, be sure the modules are NOT touching each other. Modules in contact
with other modules may cause excessive mechanical stress, which may damage the modules.

NOTES FOR CMOS DEVICES
PRECAUTION AGAINST ESD FOR MOS DEVICES
L
Exposing the MOS devices to a strong electric field can cause destruction of the gate
oxide and ultimately degrade the MOS devices operation. Steps must be taken to stop
generation of static electricity as much as possible, and quickly dissipate it, when once
it has occurred. Environmental control must be adequate. When it is dry, humidifier
should be used. It is recommended to avoid using insulators that easily build static
electricity. MOS devices must be stored and transported in an anti-static container,
static shielding bag or conductive material. All test and measurement tools including
work bench and floor should be grounded. The operator should be grounded using
wrist strap. MOS devices must not be touched with bare hands. Similar precautions
need to be taken for PW boards with semiconductor MOS devices on it.
u
od
Pr
2
HANDLING OF UNUSED INPUT PINS FOR CMOS DEVICES
No connection for CMOS devices input pins can be a cause of malfunction. If no
connection is provided to the input pins, it is possible that an internal input level may be
generated due to noise, etc., hence causing malfunction. CMOS devices behave
differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed
high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected
to VDD or GND with a resistor, if it is considered to have a possibility of being an output
pin. The unused pins must be handled in accordance with the related specifications.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Power-on does not necessarily define initial status of MOS devices. Production process
of MOS does not define the initial operation status of the device. Immediately after the
power source is turned ON, the MOS devices with reset function have not yet been
initialized. Hence, power-on does not guarantee output pin levels, I/O settings or
contents of registers. MOS devices are not initialized until the reset signal is received.
Reset operation must be executed immediately after power-on for MOS devices having
reset function.
