HB52RF649DC Product details

Description
The HB52RF649DC, HB52RD649DC are a 64M × 72 × 2 banks Synchronous Dynamic RAM Small Outline Dual In-line Memory Module (S.O.DIMM), mounted 18 pieces of 256M bits SDRAM sealed in TCP package and 1 piece of serial EEPROM (2k bits) 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.

    - PCB height: 33.02mm (1.30inch)
    - Lead pitch: 0.80mm
• 3.3V power supply
• Clock frequency: 133MHz/100MHz (max.)
• LVTTL interface
• Data bus width: × 72 ECC
• Single pulsed /RAS
• 4 Banks can operates simultaneously and independently
• Burst read/write operation and burst read/single write operation capability
• 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
