R1LV3216R Series 32Mb Advanced LPSRAM (2M word x 16bit / 4M word x 8bit) REJ03C0367-0100 Rev.1.00 2009.05.07 Description The R1LV3216R Series is a family of low voltage 32-Mbit static RAMs organized as 2,097,152-word by 16-bit, fabricated by Renesass high-performance 0.15um CMOS and TFT technologies. The R1LV3216R Series is suitable for memory applications where a simple interfacing, battery operating and battery backup are the important design objectives. The R1LV3216R Series is provided in 48-pin thin small outline package TSOP (I): 12mm x 20mm with pin pitch of 0.5mm and 52-pin micro thin small outline package TSOP (II): 10.79mm x 10.49mm with pin pitch of 0.4mm . It gives the best solution for compaction of mounting area as well as flexibility of wiring pattern of printed circuit boards. Features Single 2.7~3.6V power supply Small stand-by current: 4 A (3.0V, typical) No clocks, No refresh All inputs and outputs are TTL compatible. Easy memory expansion by CS1 , CS2, LB and UB Common Data I/O Three-state outputs: OR-tie Capability OE prevents data contention on the I/O bus Ordering Information Type No. Access time Package R1LV3216RSA-5S% 55 ns 12mm x 20mm 48-pin plastic TSOP (I) (normal-bend type) (48P3R) R1LV3216RSA-7S% 70 ns R1LV3216RSD-5S% 55 ns 350 mil 52-pin plastic -TSOP (II) (normal-bend type) (52PTG) R1LV3216RSD-7S% 70 ns % - Temperature version see table below % Temperature Range R 0 ~ +70 C I -40 ~ +85 C REJ03C0367-0100, Rev.1.00, 2009.05.07 Page 1 of 16 R1LV3216R Series Pin Arrangement A15 1 52 A16 A14 2 51 BYTE A13 3 50 UB A12 4 49 Vss A11 5 48 LB A10 6 47 DQ15/A-1 A9 7 46 DQ7 A8 8 45 DQ14 A19 9 44 DQ6 CS1 10 43 DQ13 WE 11 42 DQ5 NC 12 41 DQ12 NC 13 40 DQ4 52-pin TSOP (II) Vcc 14 39 NC CS2 15 38 DQ11 NC 16 37 DQ3 A20 17 36 DQ10 A18 18 35 DQ2 A17 19 34 DQ9 A7 20 33 DQ1 A6 21 32 DQ8 A5 22 31 DQ0 A4 23 30 OE A3 24 29 Vss A2 25 28 NC A1 26 27 A0 A15 1 48 A16 A14 2 47 BYTE A13 3 46 Vss A12 4 45 DQ15/A-1 A11 5 44 DQ7 A10 6 43 DQ14 A9 7 42 DQ6 A8 8 41 DQ13 A19 9 40 DQ5 A20 10 39 DQ12 WE 11 38 DQ4 48-pin TSOP (I) CS2 12 37 Vcc NC 13 36 DQ11 UB 14 35 DQ3 LB 15 34 DQ10 A18 16 33 DQ2 A17 17 32 DQ9 A7 18 31 DQ1 A6 19 30 DQ8 A5 20 29 DQ0 A4 21 28 OE A3 22 27 Vss A2 23 26 CS1 A1 24 25 A0 REJ03C0367-0100, Rev.1.00, 2009.05.07 Page 2 of 16
