Product details
Overview
R1LV3216RSA-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 - deployed in battery-backed memory subsystems for portable instrumentation and industrial control.
For engineers reviewing the R1LV3216RSA-5SR#S0 datasheet, R1LV3216RSA-5SR#S0 pinout, R1LV3216RSA-5SR#S0 application, or R1LV3216RSA-5SR#S0 equivalent, this page delivers verified technical context, package mapping to 48-pin TSOP (I), byte/word mode operation details, and validated alternatives for low-voltage SRAM replacement in legacy embedded designs.
Technical Context
The R1LV3216RSA-5SR#S0 implements TTL-compatible address/data I/O with no clock or refresh requirement, supporting word (16-bit) and byte (8-bit) modes via BYTE# control. Its dual chip select architecture (CS1#, CS2) enables seamless memory expansion without external logic.
It features three-state OR-tie capable outputs controlled by OE#, LB#, and UB#, with independent lower/upper byte write enable and data retention down to 2.0V VCC. Standby current remains ≤12 µA at +25°C under CS2-controlled retention mode.

Use Value: 16-bit word mode supports 16-bit parallel capture buses; no-refresh operation avoids timing jitter in sampling clocks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25616AL-10TLI | 10 ns faster access (45 ns), 3.3V only (3.135–3.465V), 44-pin SOJ package | Higher speed but narrower voltage margin; requires tighter Vcc regulation | Preferred when system clock >22 MHz and board layout allows SOJ footprint |
| AS6C4008-55ZIN | Same 55 ns access, 2.7–3.6V range, but 48-pin TSOP (I) with different pinout (no BYTE#) | Lacks byte/word mode flexibility; uses separate LB#/UB# only | Suitable for fixed 16-bit interfaces where mode switching is unnecessary |
Compared with IS61LV25616AL-10TLI and AS6C4008-55ZIN, the R1LV3216RSA-5SR#S0 uniquely combines 55 ns speed, wide 2.7–3.6V operation, byte/word mode selection, and ultra-low 4 µA standby - making it optimal for battery-constrained, thermally variable, and legacy-compatible designs requiring functional flexibility without speed sacrifice.

FAQ
What is the maximum operating frequency supported by R1LV3216RSA-5SR#S0?
The R1LV3216RSA-5SR#S0 has a 55 ns access time, enabling reliable operation with bus cycles up to approximately 18 MHz (1/55 ns). It does not require a clock signal, so timing is governed by asynchronous control signals (CS1#, WE#, OE#) meeting specified setup/hold windows per the datasheet's AC characteristics table.
Does R1LV3216RSA-5SR#S0 support both 8-bit and 16-bit data bus configurations?
Yes, the R1LV3216RSA-5SR#S0 supports both configurations via the BYTE# pin. When BYTE# is low, it operates in 8-bit mode using A-1 and DQ0–DQ7 (lower byte) or DQ8–DQ15 (upper byte); when BYTE# is high, it operates in 16-bit mode using A0–A20 and all DQ0–DQ15 lines simultaneously.
What is the minimum Vcc required to retain data in R1LV3216RSA-5SR#S0 during power-down?
The R1LV3216RSA-5SR#S0 guarantees data retention down to 2.0 V Vcc under specified conditions (CS2-controlled retention mode, ambient ≤+85°C). At +25°C, retention current is typically 4 µA, rising to 80 µA at +85°C - confirming robustness in battery-backed hold scenarios.
Is R1LV3216RSA-5SR#S0 pin-compatible with other devices in the R1LV3216R Series?
Yes, all R1LV3216R Series variants sharing the "RSA" suffix (e.g., R1LV3216RSA-7SR#S0) use the identical 48-pin TSOP (I) package and pinout. Access time and temperature grade differ, but PCB layout and firmware interface remain unchanged across same-suffix members.
How does the standby current of R1LV3216RSA-5SR#S0 compare to standard SRAMs?
The R1LV3216RSA-5SR#S0 draws only 4 µA typical standby current at 3.0V and +25°C - over 10× lower than conventional 32Mb SRAMs (typically 30–100 µA). This enables multi-year operation on coin cells in always-on monitoring applications, a key differentiator for battery-backed systems.
