Product details
Overview
R1LV3216RSD-5SR#S0 from Renesas Electronics is a 32Mb low-power static RAM organized as 2M × 16-bit or 4M × 8-bit, fabricated in 0.15µm CMOS/TFT process, operating from a single 2.7–3.6V supply with 55 ns access time and 4 µA typical standby current at 3.0V. It supports battery-backed memory applications requiring no refresh and TTL-compatible interfacing.
For engineers reviewing the R1LV3216RSD-5SR#S0 datasheet, R1LV3216RSD-5SR#S0 pinout, R1LV3216RSD-5SR#S0 application, or R1LV3216RSD-5SR#S0 equivalent, this device delivers deterministic static RAM behavior for embedded control, portable instrumentation, and industrial data logging where power efficiency, pin compatibility across byte/word modes, and long-term data retention at low VCC are critical selection criteria.
Technical Context
The R1LV3216RSD-5SR#S0 implements a fully asynchronous SRAM architecture with dual chip select (CS1#, CS2), independent upper/lower byte enables (UB#, LB#), and BYTE# mode control to switch between word and byte addressing. Its internal 2M-word × 16-bit memory array supports simultaneous 8-bit or 16-bit data transfers without clocking or refresh circuitry.
It features three-state I/O buffers with OR-tie capability, OE#-controlled bus contention prevention, and low-voltage data retention down to 2.0V with sub-12 µA current at +25°C. The device operates across 0°C to +70°C (R-grade) and uses 52-pin µTSOP (II) package with 0.4 mm pitch.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (2,097,152 × 16 or 4,194,304 × 8) |
| Access Time | 55 ns - guarantees maximum read latency under worst-case VCC/TA conditions |
| Supply Voltage | 2.7–3.6 V - enables direct interface with 3.3V logic and battery-backed systems |
| Standby Current | 4 µA typical at 3.0V - supports multi-year operation on coin-cell backup |
| Operating Temperature | 0°C to +70°C - commercial-grade thermal range for non-automotive embedded use |
| Package | 52-pin µTSOP (II), 10.79 mm × 10.49 mm, 0.4 mm pitch - compact footprint for space-constrained PCBs |
| Data Retention VCC | 2.0 V minimum - preserves stored data during brown-out or battery-switchover events |
Pinout & Package
Package: 52-pin plastic micro Thin Small Outline Package (µTSOP II), normal-bend type, 10.79 mm × 10.49 mm body, 0.4 mm pin pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address input (word mode) | 21-bit address bus supporting 2M-word addressing; A−1 used only in byte mode |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional common bus; high-impedance when disabled by OE#, LB#, UB#, or CS |
| CS1#, CS2 | Chip select inputs | Active-low hierarchical enable: CS1# primary, CS2 secondary; both required low for active operation |
| WE#, OE#, LB#, UB# | Control inputs | Asynchronous write enable, output enable, and byte-select controls - no clocks or timing constraints beyond setup/hold |
| BYTE# | Mode control | Selects word (BYTE# = H) or byte (BYTE# = L) addressing; requires LB#/UB# = L in byte mode |
| Vcc, Vss | Power/Ground | Single 2.7–3.6V supply; decoupling required per JEDEC guidelines for noise immunity |
| NC | No connect | Unbonded pins - must remain unconnected per datasheet; not usable as spares |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25616AL-10TLI | 10 ns faster access (45 ns), 3.3V-only supply (3.0–3.6V), same 52-pin TSOP-II package | Better suited for high-speed data acquisition where latency dominates power budget | Select if system timing margin is constrained and 3.3V rail is stable; verify BYTE#/LB#/UB# signal compatibility |
| AS6C4008-55PCN | Same 55 ns speed but higher standby current (15 µA typ), 28-pin SOJ package, 5V-tolerant I/O | Targets legacy 5V designs needing drop-in replacement with minimal layout change | Choose only for 5V system integration; avoid in battery-sensitive applications due to 3.75× higher ISB |
Compared with IS61LV25616AL-10TLI and AS6C4008-55PCN, the R1LV3216RSD-5SR#S0 uniquely balances ultra-low standby current (4 µA) with commercial temperature grade and flexible byte/word addressing-making it optimal for portable, battery-backed systems where energy efficiency and interface adaptability outweigh raw speed or legacy voltage support.

FAQ
What is the maximum operating frequency supported by the R1LV3216RSD-5SR#S0?
The R1LV3216RSD-5SR#S0 is an asynchronous SRAM with no internal clock; its performance is defined by access time, not frequency. With a 55 ns access time, it supports effective burst read/write rates up to approximately 18 MHz in tightly timed systems. Actual throughput depends on host interface timing margins, bus capacitance, and control signal setup/hold compliance - all verified in the AC Characteristics table on page 8 of the datasheet.
Does the R1LV3216RSD-5SR#S0 support true 8-bit operation?
Yes, the R1LV3216RSD-5SR#S0 supports native 8-bit operation via BYTE# pin assertion (LOW), which activates A−1 addressing and configures LB# and UB# to control individual byte lanes. In this mode, DQ0–DQ7 form the lower byte and DQ8–DQ15 the upper byte - enabling full 8-bit data path utilization without external multiplexing or glue logic.
Can the R1LV3216RSD-5SR#S0 retain data when Vcc drops below 2.7V?
Yes, the R1LV3216RSD-5SR#S0 guarantees data retention down to 2.0V VCC in standby mode, with typical retention current of 4 µA at 2.0V and +25°C. This feature enables reliable operation during brown-out conditions or battery voltage sag, provided CS2 is held low or CS1# is held high per the retention timing waveforms on page 16 of the datasheet.
Is the R1LV3216RSD-5SR#S0 pin-compatible with other members of the R1LV3216R family?
Yes, all R1LV3216R variants sharing the "RSD" suffix (e.g., R1LV3216RSD-5S%, R1LV3216RSD-7S%) use identical 52-pin µTSOP (II) packaging and pinout. Speed grades (-5S% = 55 ns, -7S% = 70 ns) and temperature grades (R = 0–70°C, I = −40–85°C) are pin-compatible, allowing design reuse across performance and environmental requirements.
What is the purpose of the NC pins on the R1LV3216RSD-5SR#S0?
The NC (No Connect) pins on the R1LV3216RSD-5SR#S0 - located at positions 13, 17, 25, 31, 41, and 49 per the pin arrangement diagram - are internally unbonded and electrically isolated. They must remain unconnected in PCB layout; routing traces or applying solder to these pins may cause functional failure or reliability degradation as specified in the "Pin Description" section on page 3 of the datasheet.
