| HANBit HMS51232J4V HAN BIT SRAM MODULE 2Mbyte (512Kx32Bit), 68-Pin JLCC Packaging,3.3V Part No. HMS51232J4V GENERAL DESCRIPTION The HMS51232J4V is a static random access memory (SRAM) module containing 524,288 words organized in a x32-bit configuration. The module consists of four 512K x 8 SRAMs mounted on a 68-pin, single-sided, FR4printed circuit board. Four chip enable inputs, (/CE1, /CE2, /CE3 and /CE4) are used to enable the module's 4 bytes independently. Output enable (/OE) and write enable (/WE) can set the memory input and output. Data is written into the SRAM memory when write enable (/WE) and chip enable (/CE) inputs are both LOW. Reading is accomplished when /WE remains HIGH and /CE and output enable (/OE) are LOW. For reliability, this SRAM module is designed as multiple power and ground pin. All module components may be powered from a single +3.3V DC power supply and all inputs and outputs are fully LVTTL-compatible.. FEATURES Access time : 15, 17, 20 and 25ns High-density 2MByte design High-reliability, low-power design Single +3V 0.3V power supply Three state output and LVTTL-compatible FR4-PCB design Low profile 68-Pin JLCC kxX] hX_ PIN ASSIGNMENT Vjl[ VjlZ VjlY VjlX V~l hX] hX\ hX[ kxX\ \ \_ \^ \] \\ \[ \Z \Y \X \W [ [_ [^ [] [\ hX^ OPTIONS Timing 15ns access 17ns access 20ns access 25ns access MARKING -15 -17 -20 -25 kxX^ kxX_ kxX } kxYW kxYX kxYY kxYZ } kxY[ kxY\ kxY] kxY^ } kxY_ kxY kxZW XW _ XX XY XZ X[ X\ X] X^ X_ X YW YX YY YZ Y[ Y\ ^ ] \ [ Z Y X uj uj Vvl uj } ]_ ]^ ]] ]\ ][ ]Z ]Y ]X ]W [[ Y] Y^ Y_ Y ZW ZX ZY ZZ Z[ Z\ Z] Z^ Z_ Z [W [X [Y [Z kxX[ kxXZ kxXY } kxXX kxXW kx kx_ } kx^ kx] kx\ kx[ } kxZ kxY kxX Packages 68-pin JLCC J 1 kxZX h] h\ h[ hZ hY hX hW } hXZ hXY hXX hXW h h_ h^ kxW 68-Pin JLCC TOP VIEW HANBit Electronics Co.,Ltd.
