HANBit HMS51232J4 SRAM MODULE 2Mbyte (512K x 32-Bit), 68-Pin JLCC Packaging Part No. HMS51232J4 GENERAL DESCRIPTION The HMS51232J4 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, FR4-printed 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. 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 +5V DC power supply and all inputs and outputs are fully TTL-compatible. Reading is FEATURES w Access time : 10, 12 and 15ns w High-density 2MByte design w High-reliability, low-power design w Single +5V ±0.5V power supply w Three state output and TTL-compatible w FR4-PCB design w Low profile 68-Pin JLCC PIN ASSIGNMENT DQ 1 6 A1 8 A1 7 / CE 4 / CE 3 / CE 2 / CE 1 NC V cc NC NC / OE / WE A1 6 A1 5 A1 4 DQ 1 5 DQ17 DQ18 DQ19 Vss DQ20 DQ21 DQ22 DQ23 Vcc DQ24 DQ25 DQ26 DQ27 Vss DQ28 DQ29 DQ30 10 9 8 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 7 6 5 4 3 2 1 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 26 44 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 OPTIONS w Timing 10ns access 12ns access 15ns access w Packages 68-pin JLCC MARKING -10 -12 -15 J URL: www.hbe.co.kr Rev. 1.0 (September / 2002) 1 DQ 3 1 A6 A5 A4 A3 A2 A1 A0 V cc A1 3 A1 2 A1 1 A1 0 A9 A8 A7 DQ 0 HANBit Electronics Co.,Ltd. 68-Pin JLCC TOP VIEW DQ14 DQ13 DQ12 Vss DQ11 DQ10 DQ9 DQ8 Vcc DQ7 DQ6 DQ5 DQ4 Vss DQ3 DQ2 DQ1 HANBit PIN DESCRIPTION DQ0 – DQ31 A0 – A18 /WE /CE1-4 /OE Vcc Vss Data Inputs/Outputs Address Inputs Write Enable Chip Selects Output Enable Power Supply Ground HMS51232J4 BLOCK DIAGRAM /CE1 /WE /OE A0-18 /CE2 /CE3 /CE4 U1 512Kx8 U2 512Kx8 U3 512Kx8 U4 512Kx8 8 8 8 8 DQ0-7 DQ8-15 DQ16-23 DQ24-31 TRUTH TABLE MODE STANDBY NOT SELECTED READ WRITE /OE X H L X /CE H L L L /WE X H H L DQ HIGH-Z HIGH-Z Dout Din POWER STANDBY ACTIVE ACTIVE ACTIVE URL: www.hbe.co.kr Rev. 1.0 (September / 2002) 2 HANBit Electronics Co.,Ltd. HANBit ABSOLUTE MAXIMUM RATINGS PARAMETER Voltage on Any Pin Relative to Vss Voltage on Vcc Supply Relative to Vss Power Dissipation Storage Temperature Operating Temperature SYMBOL VIN,OUT VCC PD TSTG TA HMS51232J4 RATING -0.5V to +7.0V -0.5V to +7.0V 4W oC to +125oC -55 0oC to +70oC w Stresses greater than those listed under " Absolute Maximum Ratings" may cause permanent damage to the device.
