Product details
Overview
R1LV3216RSA-5SR#B0 from Renesas Electronics is a 32Mb low-power static RAM organized as 2M × 16-bit (or 4M × 8-bit in byte mode), fabricated on 0.15µm CMOS/TFT process, operating from 2.7V to 3.6V 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#B0 datasheet, R1LV3216RSA-5SR#B0 pinout, R1LV3216RSA-5SR#B0 application, or R1LV3216RSA-5SR#B0 equivalent, key selection criteria include single-supply LPSRAM operation, TTL-compatible I/O, no-refresh architecture, byte/word mode flexibility via BYTE#, and TSOP(I) 48-pin packaging for space-constrained PCB layouts.
Technical Context
This device implements a fully asynchronous SRAM core with dual chip select (CS1#, CS2), independent upper/lower byte enables (UB#, LB#), and output enable (OE#) to support multi-bank memory expansion without external logic. Its BYTE# pin configures address mapping between word mode (A0–A20) and byte mode (A−1–A20), enabling seamless 8-bit or 16-bit data bus interfacing.
The memory array delivers deterministic read/write timing under all valid combinations of CS1#, CS2, WE#, OE#, LB#, and UB#, with tAA = 55 ns, tWC = 55 ns, and tOE = 25 ns at Vcc = 2.7–3.6V and Ta = 0°C to +70°C. Standby current drops to 4 µA (typ.) at 3.0V, supporting extended battery retention down to 2.0V with ICCDR ≤ 80 µA at +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory capacity | 32 Mbit (2,097,152 × 16-bit or 4,194,304 × 8-bit) - supports both word and byte addressing modes via BYTE# control. |
| Access time | 55 ns - guarantees maximum read latency for real-time control loops requiring deterministic memory response. |
| Supply voltage | 2.7–3.6 V - compatible with 3.3V logic systems and enables direct integration into battery-powered designs. |
| Standby current | 4 µA typical at 3.0V - minimizes quiescent power draw during sleep or backup states in portable equipment. |
| Operating temperature | 0°C to +70°C (R-grade) - qualified for commercial and industrial ambient environments without derating. |
| Package | 48-pin TSOP(I), 12 mm × 20 mm, 0.5 mm pitch - surface-mount compatible with standard reflow profiles and high-density routing. |
| Data retention voltage | 2.0 V minimum - maintains stored data during brown-out or battery-switchover without external backup circuitry. |
Pinout & Package
Package: 48-pin Thin Small Outline Package (TSOP I), 12 mm × 20 mm, 0.5 mm lead pitch, normal-bend leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address input (word mode) | 21-bit address bus for 2M-word addressing; A−1 used only in byte mode when BYTE# = L. |
| DQ0–DQ15 | Data I/O bidirectional | 16-bit common data bus; three-state outputs support OR-tie bus sharing and prevent contention. |
| CS1#, CS2 | Chip select inputs | Two-level decode enables memory banking; CS2 = L forces standby regardless of CS1# state. |
| WE#, OE#, LB#, UB# | Control inputs | Asynchronous write/read/byte-enable signals - no clocks or refresh required; supports partial-word writes. |
| BYTE# | Mode configuration | Selects between 16-bit word mode (H) and 8-bit byte mode (L); requires LB# = UB# = L in byte mode. |
| Vcc, Vss | Power and ground | Single 2.7–3.6V supply; decoupling required per JEDEC TSOP layout guidelines for signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| No refresh required | Eliminates system-level DRAM controller overhead and timing-critical refresh cycles - simplifies firmware and reduces CPU load. |
| TTL-compatible I/O | VIH = 2.4 V min, VIL = 0.4 V max - interoperable with legacy 3.3V microcontrollers and FPGAs without level-shifting. |
| Byte/word mode switching | Configurable via BYTE# pin - enables same part to serve 8-bit and 16-bit host interfaces without redesign. |
| OR-tie capable outputs | Three-state DQ lines support wired-OR bus architectures - allows multiple SRAMs to share a single data bus with external arbitration. |
| Low-voltage data retention | Maintains valid data at Vcc ≥ 2.0 V - extends operational window during power failover and enables seamless battery backup. |
Applications
| Portable Medical Monitors | Industrial PLC Data Logging |

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 (3.135–3.465V), 44-pin SOJ package | Higher speed but narrower Vcc tolerance and different footprint - unsuitable for battery-voltage variation or TSOP-replacement. | Select only if board layout accommodates SOJ and system operates strictly within tight 3.3V ±5% rails. |
| AS6C4008-55PCN | Same 55 ns speed, 2.7–3.6V, but 48-pin TSOP(I) with 0.5 mm pitch - pinout differs in A19/A20/CS2 placement and lacks BYTE# pin | Requires PCB redesign due to incompatible pin mapping and no byte-mode capability - limits flexibility in mixed-bus systems. | Consider only for cost-sensitive volume builds where byte-mode functionality is unused and layout revision is acceptable. |
Compared with IS61LV25616AL-10TLI and AS6C4008-55PCN, the R1LV3216RSA-5SR#B0 uniquely combines 55 ns speed, wide 2.7–3.6V operation, byte/word configurability, and TSOP(I)-compatible pinout - making it the only drop-in option for battery-backed 16-bit memory expansion without layout or firmware changes.

FAQ
What is the guaranteed access time for R1LV3216RSA-5SR#B0 across its full operating voltage and temperature range?
The R1LV3216RSA-5SR#B0 guarantees 55 ns maximum address access time (tAA) over the full specified range of Vcc = 2.7–3.6 V and Ta = 0°C to +70°C. This value is validated per AC characteristics table on page 8 of the datasheet and applies to all valid read cycle configurations including CS1#- or CS2-controlled access.
Does R1LV3216RSA-5SR#B0 support true 8-bit operation, and how is it configured?
Yes, R1LV3216RSA-5SR#B0 supports true 8-bit operation via the BYTE# pin. When BYTE# = L, the device enters byte mode and uses A−1 as the LSB address, enabling 4M × 8-bit organization. In this mode, LB# and UB# must both be asserted low to enable lower or upper byte access, as defined in the Operation Table on page 5.
What is the minimum supply voltage at which R1LV3216RSA-5SR#B0 retains stored data, and under what conditions?
R1LV3216RSA-5SR#B0 retains stored data down to Vcc = 2.0 V, provided CS2 is held low (standby mode) or CS1# is high with CS2 in valid logic range, as specified in the Low Vcc Data Retention Characteristics table on page 15. This behavior is tested and guaranteed across the full temperature range up to +85°C.
Can R1LV3216RSA-5SR#B0 be used in systems with mixed 3.3V and 5V logic families?
No - R1LV3216RSA-5SR#B0 is strictly a 3.3V-family device with VIH = 2.4 V min and VIL = 0.4 V max. It is not 5V-tolerant: applying 5V signals to any input pin exceeds the absolute maximum rating of Vcc + 0.3 V and risks permanent damage. Level translation is required for interfacing with 5V logic.
Is the R1LV3216RSA-5SR#B0 pinout compatible with other 48-pin TSOP(I) SRAMs such as the AS6C4008 series?
No - the R1LV3216RSA-5SR#B0 pinout is not compatible with AS6C4008-series devices. Key differences include relocation of A19/A20, CS2 position, and presence of the BYTE# pin (absent in AS6C4008). The pin arrangement diagram on page 2 confirms unique signal mapping that prevents direct substitution without PCB modification.
