Product details
Overview
R1LV0216BSB-5SI#S1 from Renesas Electronics is a 2Mb low-power static RAM organized as 131,072 × 16-bit, fabricated in 0.15µm CMOS/TFT technology, operating from 2.7V to 3.6V with 55 ns access time and 1 µA typical standby current at 3.0V, used in battery-backed memory systems requiring no refresh and TTL-compatible interfacing.
For engineers reviewing the R1LV0216BSB-5SI#S1 datasheet, R1LV0216BSB-5SI#S1 pinout, R1LV0216BSB-5SI#S1 application, or R1LV0216BSB-5SI#S1 equivalent, key selection criteria include single-supply operation, byte-selectable write capability via LB#/UB#, three-state I/O with OR-tie support, and TSOP (II) packaging for space-constrained embedded designs.
Technical Context
The R1LV0216BSB-5SI#S1 implements a fully asynchronous SRAM architecture with independent upper/lower byte enables (UB#/LB#), chip select (CS#), output enable (OE#), and write enable (WE#), supporting word, upper-byte, and lower-byte write operations without clocks or refresh cycles. Its address buffer, sense/write amplifier, and column/row decoder are all powered directly from Vcc.
It features dual data retention modes triggered either by CS# ≥ Vcc−0.2V or LB#/UB# ≥ Vcc−0.2V while CS# ≤ 0.2V, enabling ultra-low ICCDR of 1 µA at +25°C during backup operation at Vcc as low as 2.0V - critical for long-term battery hold applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 2 Mb (131,072 × 16-bit) - supports 16-bit data bus systems without external width expansion. |
| Access time | 55 ns - ensures compatibility with legacy 16-bit microcontrollers and DSPs running at ≤18 MHz. |
| Supply voltage | 2.7V–3.6V - matches Li-ion battery discharge profile and eliminates need for voltage regulation in portable devices. |
| Standby current | 1 µA typical at 3.0V - enables multi-year data retention on coin-cell batteries in backup mode. |
| Operating temperature | −40°C to +85°C - qualified for industrial and automotive under-hood environments. |
| I/O interface | TTL-compatible inputs/outputs - simplifies direct connection to 3.3V logic families without level shifters. |
| Data retention Vcc min | 2.0V - guarantees nonvolatile data hold even during brown-out conditions below nominal supply. |
Pinout & Package
Package: 44-pin 400-mil plastic TSOP (II), surface-mount, JEDEC standard footprint with 0.8 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Vcc | Power supply | Single 2.7–3.6V supply input; powers all internal logic and memory array. |
| Vss (GND) | Ground reference | Dual ground pins (pins 11 and 35) reduce noise coupling and improve signal integrity. |
| A0–A16 | Address inputs | 17-bit address bus selects one of 131,072 16-bit words; A4–A0 mapped to pins 1–5 per TSOP layout. |
| DQ0–DQ15 | Data I/O | Bidirectional 16-bit data bus with three-state outputs; supports OR-tie for shared-bus configurations. |
| CS# | Chip select | Active-low global enable; places device in standby when high, enabling system-level power gating. |
| WE# | Write enable | Active-low control for write cycles; combined with LB#/UB# to select byte/word write granularity. |
| OE# | Output enable | Active-low control for read data output; prevents bus contention when multiple devices share DQ lines. |
| LB#, UB# | Byte enables | Independent active-low controls for lower (DQ0–7) and upper (DQ8–15) byte writes - eliminates need for external byte masking logic. |
| NC | No connect | Pins 23 and 44 are unconnected; must remain floating or grounded per PCB design rules. |
Key Features
| Feature | Design Value |
|---|---|
| No refresh required | Asynchronous SRAM architecture eliminates DRAM-style refresh circuitry, reducing MCU firmware overhead and system complexity. |
| Byte-selectable write | LB# and UB# enable independent 8-bit writes without disturbing adjacent bytes - essential for efficient protocol stack buffer management. |
| Ultra-low standby current | 1 µA typical at 3.0V allows >10-year data retention on CR2032 coin cells in backup mode - validated across −40°C to +85°C. |
| TTL-compatible I/O | VIH = 2.2V min, VIL = 0.6V max ensures reliable interfacing with legacy 3.3V microcontrollers and FPGAs without level translation. |
| OR-tie capable outputs | Three-state DQ drivers support wired-OR bus topologies - simplifies multi-device memory expansion without external bus transceivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power parallel SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62128ELL-55ZSXIT (Infineon) | Same 128k×16 organization, 55 ns access, but 2.2–5.5V supply range and higher 2 µA standby current at 3.0V. | Lacks dedicated LB#/UB# pins - requires external byte-enable logic for partial writes. | Choose when wider voltage tolerance is needed and byte-select logic is already present on board. |
| IS61LV25616AL-10TLI (ISSI) | 256k×16 density (512 kb), 10 ns faster access (45 ns), but 5 µA typical standby current and no data retention spec below 2.7V. | Higher speed suits real-time control loops; higher ISB limits battery backup duration. | Choose when system clock rate exceeds 22 MHz and battery lifetime is secondary to throughput. |
Compared with CY62128ELL-55ZSXIT and IS61LV25616AL-10TLI, the R1LV0216BSB-5SI#S1 delivers superior battery-backed longevity due to its 1 µA standby and 2.0V data retention, while maintaining pin-compatible TSOP (II) footprint and native byte-write control - making it optimal for long-life, low-power embedded memory.

FAQ
What is the minimum supply voltage required to retain data in R1LV0216BSB-5SI#S1?
The R1LV0216BSB-5SI#S1 guarantees data retention down to 2.0V when placed in retention mode via CS# ≥ Vcc−0.2V or LB#/UB# ≥ Vcc−0.2V with CS# ≤ 0.2V. This specification is tested and documented in the Low Vcc Data Retention Characteristics table on page 12 of the R10DS0273EJ0101 datasheet. Below 2.0V, data integrity is not assured.
Does R1LV0216BSB-5SI#S1 require an external clock or refresh signal?
No, the R1LV0216BSB-5SI#S1 is a fully asynchronous static RAM and does not require any clock or refresh signal. All operations - read, write, and standby - are controlled solely by the timing relationships among CS#, WE#, OE#, LB#, and UB# as defined in the Operation Table on page 4 of the datasheet. This eliminates refresh overhead in MCU firmware.
What is the meaning of "#S1" in R1LV0216BSB-5SI#S1?
The "#S1" suffix in R1LV0216BSB-5SI#S1 indicates embossed tape packaging (as opposed to "#B1" for tray packaging), per the Ordering Information table on page 1 of the R10DS0273EJ0101 datasheet. It denotes the same electrical and thermal specifications as R1LV0216BSB-5SI#B1, differing only in shipping format for automated SMT assembly.
Can R1LV0216BSB-5SI#S1 be used in a 3.3V-only system without level shifters?
Yes, the R1LV0216BSB-5SI#S1 has TTL-compatible inputs (VIH = 2.2V min, VIL = 0.6V max) and outputs (VOH = 2.4V min at –0.5mA), making it fully interoperable with standard 3.3V logic families such as 74LVC and ARM GPIOs. No level-shifting circuitry is required for direct connection.
How does the byte-enable functionality work in R1LV0216BSB-5SI#S1?
In the R1LV0216BSB-5SI#S1, LB# enables writes to DQ0–DQ7 (lower byte) and UB# enables writes to DQ8–DQ15 (upper byte). When both are low, a full 16-bit word write occurs. The Operation Table (page 4) confirms that simultaneous assertion of LB# and UB# with WE# low performs word write, while individual activation supports byte-granularity updates without affecting adjacent data.
