Product details
Overview
R1LV0216BSB-5SI#S0 from Renesas Electronics is a 2Mb low-power static RAM organized as 131,072 × 16-bit, fabricated in 0.15µm CMOS/TFT process, operating on single 2.7–3.6V supply with 55ns access time and 1µA typical standby current at 3.0V, used in battery-backed memory subsystems for industrial controllers and portable instrumentation.
For engineers reviewing the R1LV0216BSB-5SI#S0 datasheet, R1LV0216BSB-5SI#S0 pinout, R1LV0216BSB-5SI#S0 application, or R1LV0216BSB-5SI#S0 equivalent, key selection criteria include TSOP(II)-44 package compatibility, byte-selectable 16-bit I/O architecture, no-refresh operation, TTL-compatible interface timing, and low-voltage data retention down to 2.0V.
Technical Context
This LPSRAM implements asynchronous, non-volatile-retentive SRAM architecture with independent upper/lower byte enables (UB#/LB#), chip select (CS#), write enable (WE#), and output enable (OE#) for flexible memory expansion and bus sharing. All control and data signals are TTL-compatible with VIH ≥ 2.2V and VIL ≤ 0.6V.
The device supports three write modes-word, upper-byte, and lower-byte-via CS#, WE#, LB#, and UB# combinations, and guarantees data retention at Vcc ≥ 2.0V with ICCDR ≤ 10µA at +85°C. No clocks or refresh circuitry are required, eliminating system-level timing overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 2 Mbit (131,072 × 16-bit) - provides 256KB of word-addressable storage without external address multiplexing |
| Access time | 55 ns - ensures compatibility with 18 MHz bus systems using standard asynchronous read/write cycles |
| Supply voltage | 2.7–3.6 V - supports direct connection to 3.3V logic rails and battery-backed operation down to 2.0V for data retention |
| Standby current | 1 µA typical at 3.0V/25°C - enables multi-year battery life in always-on backup memory applications |
| I/O interface | TTL-compatible inputs/outputs - eliminates level-shifter requirements when interfacing with legacy microcontrollers and FPGAs |
| Package | 44-pin TSOP (II), 400-mil - industry-standard footprint compatible with automated SMT assembly and existing PCB layouts |
| Data retention Vcc | 2.0–3.6 V - maintains stored data during brown-out or battery-switchover without external power management ICs |
Pinout & Package
44-pin plastic TSOP (II) package, 400-mil body width, JEDEC MO-141AC compliant, with 0.8mm lead pitch and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Vcc | Power supply | Primary 2.7–3.6V supply rail; decoupling capacitor placement critical for noise immunity during high-speed reads/writes |
| Vss (GND) | Ground | Signal and power return path; two dedicated pins (pins 11 & 35) reduce ground bounce in high-frequency operation |
| A0–A16 | Address input | 17-bit address bus supporting full 131k-word decoding; A4–A0 mapped to pins 1–5 per standard TSOP layout |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus with three-state outputs; OR-tie capability allows shared bus topology without external logic |
| CS# | Chip select | Active-low enable controlling all internal buffers; assertion initiates read/write; deassertion forces high-Z outputs |
| WE# | Write enable | Active-low control for write operations; combined with CS# and LB#/UB# determines byte/word write mode |
| OE# | Output enable | Active-low gate for output drivers; prevents bus contention during multi-device sharing or CPU wait-state insertion |
| LB#, UB# | Byte enable | Independent active-low controls for lower (DQ0–7) and upper (DQ8–15) bytes; enables partial writes without read-modify-write |
| NC | Non-connected | Pins 23 and 44 are unconnected; must remain floating or tied to GND per design guidelines to avoid noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| No clock, no refresh | Eliminates system-level timing constraints and reduces firmware complexity-ideal for simple microcontroller-based data loggers |
| 1 µA standby current (typ.) | Enables >5-year battery backup with standard CR2032 cells in low-duty-cycle monitoring applications |
| Byte-selectable 16-bit I/O | Supports 8-bit or 16-bit host buses via LB#/UB#; avoids glue logic and simplifies migration from legacy 8-bit SRAMs |
| 2.0V data retention | Maintains memory contents during power failover or deep sleep without external hold-up capacitors or supervisory circuits |
| TTL-compatible signaling | Direct interface with 3.3V/5V microcontrollers, CPLDs, and ASICs-no level translation required in mixed-voltage systems |

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 |
|---|---|---|---|
| CY62128EV30LL-45ZSXIT | 45ns access time, 2.2–5.5V supply range, 48-pin TSOP-I package | Wider voltage range supports 5V legacy systems; larger package requires PCB redesign | Select when 5V tolerance or faster access is required and board space permits 48-pin layout |
| IS61LV25616AL-10TLI | 10ns access time, 3.0–3.6V supply, 44-pin TSOP-II, higher ICC1 (30mA max) | Higher speed but increased active power; identical pinout and voltage range | Select when system timing budget demands sub-10ns read latency and thermal management accommodates higher dissipation |
Compared with CY62128EV30LL-45ZSXIT and IS61LV25616AL-10TLI, the R1LV0216BSB-5SI#S0 offers optimal balance of ultra-low standby current (1µA), 55ns timing, and strict 2.7–3.6V compliance-making it preferred for battery-constrained, cost-sensitive industrial and medical edge devices where pinout compatibility and long-term supply stability are critical.

FAQ
What is the maximum operating temperature range for the R1LV0216BSB-5SI#S0?
The R1LV0216BSB-5SI#S0 is rated for operation from –40°C to +85°C ambient temperature. This industrial-grade temperature range ensures reliable performance in factory automation equipment, outdoor metering devices, and medical diagnostics hardware where environmental extremes are common. The device's standby current specification (≤10µA at +85°C) confirms thermal stability under worst-case conditions.
Does the R1LV0216BSB-5SI#S0 require external refresh circuitry?
No, the R1LV0216BSB-5SI#S0 is a true static RAM and does not require any refresh cycles or external clock signals. Its architecture uses flip-flop-based memory cells, enabling indefinite data retention as long as power is applied and control signals meet timing specifications. This eliminates refresh overhead in microcontroller firmware and simplifies system design compared to DRAM solutions.
Can the R1LV0216BSB-5SI#S0 be used with a 5V microcontroller interface?
No-the R1LV0216BSB-5SI#S0 is strictly a 2.7–3.6V device with TTL-compatible input thresholds (VIH ≥ 2.2V, VIL ≤ 0.6V). Direct connection to 5V logic violates absolute maximum ratings and risks permanent damage. A level-shifting buffer or voltage translator is required for interoperability with 5V hosts, unlike wider-supply alternatives such as the CY62128EV30LL-45ZSXIT.
What is the significance of the "-5SI#S0" suffix in R1LV0216BSB-5SI#S0?
The "-5SI#S0" suffix denotes a specific ordering variant of the R1LV0216BSB family: "5" indicates 55ns access time, "S" specifies industrial temperature grade (–40°C to +85°C), "I" identifies the 44-pin TSOP(II) package, and "#S0" refers to embossed tape packaging format per Renesas' ordering nomenclature. This exact variant is optimized for automated SMT assembly in high-reliability applications.
How does the R1LV0216BSB-5SI#S0 support byte-level writes without read-modify-write?
The R1LV0216BSB-5SI#S0 implements dedicated LB# (pins 32–33) and UB# (pin 31) controls that independently gate the lower and upper data bytes during write cycles. When only LB# is asserted low with WE# and CS#, only DQ0–DQ7 are written; similarly, asserting only UB# writes DQ8–DQ15. This eliminates the need for external latches or firmware-level masking, reducing bus turnaround time and CPU load.
