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 Renesas’s 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 [µTSOP (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 µA (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. R1LV3216RSA-5S% R1LV3216RSA-7S% R1LV3216RSD-5S% R1LV3216RSD-7S% Access time 55 ns 70 ns 55 ns 70 ns Package 12mm x 20mm 48-pin plastic TSOP (I) (normal-bend type) (48P3R) 350 mil 52-pin plastic μ-TSOP (II) (normal-bend type) (52PTG) % R I % - Temperature version; see table below Temperature Range 0 ~ +70 °C -40 ~ +85 °C REJ03C0367-0100, Rev.1.00, 2009.05.07 Page 1 of 16 R1LV3216R Series Pin Arrangement A15 A14 A13 A12 A11 A10 A9 A8 A19 CS1# WE# NC NC Vcc CS2 NC A20 A18 A17 A7 A6 A5 A4 A3 A2 A1 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 52 51 50 49 48 47 46 45 44 43 42 41 A16 BYTE# UB# Vss LB# DQ15/A-1 DQ7 DQ14 DQ6 DQ13 DQ5 DQ12 DQ4 NC DQ11 DQ3 DQ10 DQ2 DQ9 DQ1 DQ8 DQ0 OE# Vss NC A0 52-pin μTSOP (II) 40 39 38 37 36 35 34 33 32 31 30 29 28 27 A15 A14 A13 A12 A11 A10 A9 A8 A19 A20 WE# CS2 NC UB# LB# A18 A17 A7 A6 A5 A4 A3 A2 A1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 48 47 46 45 44 43 42 41 40 39 38 A16 BYTE# Vss DQ15/A-1 DQ7 DQ14 DQ6 DQ13 DQ5 DQ12 DQ4 Vcc DQ11 DQ3 DQ10 DQ2 DQ9 DQ1 DQ8 DQ0 OE# Vss CS1# A0 48-pin TSOP (I) 37 36 35 34 33 32 31 30 29 28 27 26 25 REJ03C0367-0100, Rev.1.00, 2009.05.07 Page 2 of 16 R1LV3216R Series Pin Description Pin name Vcc Vss A0 to A20 A-1 to A20 DQ0 to DQ15 CS1# CS2 WE# OE# LB# UB# BYTE# NC Function Power supply Ground Address input (word mode) Address input (byte mode) Data input/output Chip select 1 Chip select 2 Write enable Output enable Lower byte enable Upper byte enable Byte control mode enable Non connection REJ03C0367-0100, Rev.1.00, 2009.05.07 Page 3 of 16 R1LV3216R Series Block Diagram A0 A1 ADDRESS BUFFER ROW DECODER MEMORY ARRAY 2M-word x16-bit or 4M-word x 8-bit DQ0 DQ1 A20 DQ BUFFER DATA SENSE / WRITE AMPLIFIER SELECTOR DQ7 DQ8 COLUMN DECODER DQ BUFFER CLOCK DQ9 CS2 CS1# LB# GENERATOR DQ15 / A -1 X8 / x16 Vcc Vss UB# CONTROL BYTE# WE# OE# REJ03C0367-0100, Rev.1.00, 2009.05.07 Page 4 of 16 R1LV3216R Series Operation Table CS1# H X X L L L L L L L L L L L L CS2 X L X H H H H H H H H H H H H BYTE# X X H H H H H H H H H H L L L LB# X X H L L L H H H L L L L L L UB# X X H H H H L L L L L L L L L WE# X X X L H H L H H L H H L H H OE# X X X X L H X L H X L H X L H DQ0~7 High-Z High-Z High-Z Din Dout High-Z High-Z High-Z High-Z Din Dout High-Z Din Dout High-Z DQ8~14 High-Z High-Z High-Z High-Z High-Z High-Z Din Dout High-Z Din Dout High-Z High-Z High-Z High-Z DQ15 High-Z High-Z High-Z High-Z High-Z High-Z Din Dout High-Z Din Dout High-Z A-1 A-1 A-1 Operation Stand-by Stand-by Stand-by Write in lower byte Read in lower byte Output disable Write in upper byte Read in upper byte Output disable Word write Word read Output disable Byte write Byte read Output disable Note 1.
