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

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

• 144-pin Zig Zag Dual tabs socket type (dual lead out)

Outline: 38.00mm (Length) × 30.00mm (Height) ×

3.80mm (Thickness)

Lead pitch: 0.50mm

• 3.3V power supply

• Clock frequency: 133MHz/100MHz (max.)

• LVTTL interface

• Data bus width: × 64 Non parity

• Single pulsed /RAS

inputs and outputs.

Decoupling capacitors are

• 4 Banks can operates simultaneously and

independently

mounted beside TCP on the module board.

• Burst read/write operation and burst read/single write

operation capability

Note: Do not push the cover or drop the modules in

order to protect from mechanical defects, which

would be electrical defects.

• Programmable burst length (BL): 1, 2, 4, 8

• 2 variations of burst sequence

Sequential

Interleave

• Programmable /CE latency (CL): 2, 3

• Byte control by DQMB

• Refresh cycles: 8192 refresh cycles/64ms

• 2 variations of refresh

Auto refresh

Self refresh

• Low self refresh current : HB52RF328GB-xxBL

: HB52RD328GB-xxBL
