3 / 17 page DRAM MODULE KMM5321200C2W/C2WG Rev. 0.0 (Nov. 1997) - 3 - KMM5321200C2W/C2WG with Fast Page Mode 1M x 32 DRAM SIMM using 1Mx16, 1K Refresh, 5V The Samsung KMM5321200C2W is a 1Mx32bits Dynamic RAM high density memory module. The Samsung KMM5321200C2W consists of two CMOS 1Mx16bits DRAMs in 42-pin SOJ packages mounted on a 72-pin glass-epoxy substrate. A 0.1 or 0.22uF decoupling capacitor is mounted on the printed circuit board for each DRAM. The KMM5321200C2W is a Single In-line Memory Module with edge connections and is intended for mounting into 72 pin edge connector sockets. • Part Identification - KMM5321200C2W(1024 cycles/16ms Ref, SOJ, Solder) - KMM5321200C2WG(1024 cycles/16ms Ref, SOJ, Gold) • Fast Page Mode Operation • CAS-before-RAS refresh capability • RAS-only refresh capability • TTL compatible inputs and outputs • Single +5V ±10% power supply • JEDEC standard PDPin & pinout • PCB : Height(750mil), single sided component GENERAL DESCRIPTION FEATURES PERFORMANCE RANGE Speed tRAC tCAC tRC -5 50ns 15ns 90ns -6 60ns 15ns 110ns PIN NAMES Pin Name Function A0 - A9 Address Inputs DQ0 - DQ31 Data In/Out W Read/Write Enable RAS0 Row Address Strobe CAS0 - CAS3 Column Address Strobe PD1 -PD4 Presence Detect Vcc Power(+5V) Vss Ground NC No Connection Res Reserved Pin PRESENCE DETECT PINS (Optional) * Pin connection changing available Pin 50NS 60NS PD1 PD2 PD3 PD4 Vss Vss Vss Vss Vss Vss NC NC PIN CONFIGURATIONS Pin 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 Symbol VSS DQ0 DQ16 DQ1 DQ17 DQ2 DQ18 DQ3 DQ19 Vcc NC A0 A1 A2 A3 A4 A5 A6 Res(A10) DQ4 DQ20 DQ5 DQ21 DQ6 DQ22 DQ7 DQ23 A7 Res(A11) Vcc A8 A9 Res(RAS1) RAS0 NC NC Pin 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 Symbol NC NC Vss CAS0 CAS2 CAS3 CAS1 RAS0 Res(RAS1) NC W NC DQ8 DQ24 DQ9 DQ25 DQ10 DQ26 DQ11 DQ27 DQ12 DQ28 Vcc DQ29 DQ13 DQ30 DQ14 DQ31 DQ15 NC PD1 PD2 PD3 PD4 NC Vss SAMSUNG ELECTRONICS CO., LTD. reserves the right to change products and specifications without notice. |
