Product details
Overview
R1LV1616RSD-7UR#B0 from Renesas Electronics is a 16-Mbit CMOS static RAM organized as 1-Mword × 16-bit or 2-Mword × 8-bit, operating from a single 3.0 V supply (2.7–3.6 V), with 55 ns max access time and −40°C to +85°C industrial temperature range. It supports battery backup via dual chip select (CS1#, CS2) and byte-select functionality (UB#, LB#, BYTE#) for embedded control and data logging systems.
For engineers reviewing the R1LV1616RSD-7UR#B0 datasheet, R1LV1616RSD-7UR#B0 pinout, R1LV1616RSD-7UR#B0 application, or R1LV1616RSD-7UR#B0 equivalent, this device delivers low-power standby operation (1.5 µW typ), three-state I/O, and full static operation without clocks-critical for power-sensitive instrumentation and industrial microcontroller peripherals.
Technical Context
The R1LV1616RSD-7UR#B0 implements a fully static 6-transistor memory cell architecture enabling zero-refresh operation and deterministic timing across its entire voltage and temperature range. Its dual-mode addressing (A0–A19 in word mode; A−1–A19 in byte mode) and independent upper/lower byte enable (UB#, LB#) support flexible data bus interfacing with 8-bit or 16-bit microcontrollers.
It features three distinct standby entry paths-via CS2 low, CS1# high with CS2 high, or simultaneous UB#/LB# high-each yielding sub-µA retention current (0.5 µA typ at VCC = 3.0 V). The device uses a 48-pin plastic TSOPI package with 0.5 mm pitch and surface-mount footprint optimized for high-density PCB layouts.

Applications
| Industrial Data Logger | Medical Diagnostic Monitor |
|---|---|
Use Scenario: Continuous acquisition of sensor data (ECG, SpO₂, temperature) with periodic flash storage and real-time display buffering. IC Role / Device Role / Timing Role: High-reliability, low-power SRAM acting as volatile frame buffer and intermediate FIFO between ADC and display controller. Use Value: 55 ns access time ensures seamless 60 Hz display updates; 0.5 µA standby current preserves battery charge during sleep intervals between measurements. |

IC Role / Device Role / Timing Role: Battery-backed SRAM maintaining critical configuration data when main 12 V supply is disconnected. Use Value: Sub-µA retention current enables >5-year data hold on a single CR2032; VDR down to 1.5 V ensures reliable operation during brown-out conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV1616AL-10TLI | 10 ns faster access (45 ns max), same 48-pin TSOPI package, identical 16-Mbit × 16/×8 organization | Higher-speed requirement in real-time DSP co-processing; not rated for extended temperature range | Select when system clock exceeds 12 MHz and ambient temperature stays within 0°C to +70°C |
| AS6C1616-55PCN | Same 55 ns access, but only −20°C to +70°C temp range; lower standby current (0.2 µA typ) and smaller 44-pin TSOP package | Consumer-grade portable electronics where cost and board space outweigh industrial reliability needs | Choose for cost-sensitive consumer designs with relaxed thermal and longevity requirements |
Compared with IS61LV1616AL-10TLI, R1LV1616RSD-7UR#B0 trades 10 ns speed for guaranteed −40°C operation and robust battery-backup control; versus AS6C1616-55PCN, it adds industrial temperature qualification and dual-CS retention at modest cost premium.

FAQ
What is the maximum access time specification for R1LV1616RSD-7UR#B0?
The R1LV1616RSD-7UR#B0 has a maximum access time of 55 ns under industrial temperature (−40°C to +85°C) and supply voltage (2.7 V to 3.6 V) conditions. This value is measured as tAA (address access time) and applies to both word and byte modes. The device also meets 55 ns max for tACS1, tACS2, and tBA, ensuring consistent timing across all control signal combinations.
Does R1LV1616RSD-7UR#B0 support true 8-bit data bus operation?
Yes, R1LV1616RSD-7UR#B0 supports native 8-bit operation via BYTE# pin assertion, which shifts the address LSB from A0 (in 16-bit word mode) to A−1 (in 8-bit byte mode), enabling 2-Mword × 8-bit organization. Combined with independent LB# and UB# controls, it allows true byte-wide reads/writes without read-modify-write overhead.
How does R1LV1616RSD-7UR#B0 enter ultra-low-power data retention mode?
R1LV1616RSD-7UR#B0 enters data retention mode through any of three hardware-configured paths: (1) CS2 ≤ 0.2 V, (2) CS1# ≥ VCC − 0.2 V with CS2 ≥ VCC − 0.2 V, or (3) LB# = UB# ≥ VCC − 0.2 V with CS2 ≥ VCC − 0.2 V and CS1# ≤ 0.2 V. All paths reduce ICCDR to 0.5 µA typ while preserving data at VCC as low as 1.5 V.
What is the pin compatibility status of R1LV1616RSD-7UR#B0 with other devices in the R1LV1616H-I Series?
R1LV1616RSD-7UR#B0 is pin-compatible with all members of the R1LV1616H-I Series, including R1LV1616HSA-4LI, R1LV1616HSA-4SI, and R1LV1616HSA-5SI. All share identical 48-pin TSOPI (48P3R-B) pinout, address/data/control signal assignments, and DC/AC electrical characteristics-differing only in access time grade and ordering suffix.
Can R1LV1616RSD-7UR#B0 operate reliably at 2.7 V supply voltage?
Yes, R1LV1616RSD-7UR#B0 is fully specified and tested at 2.7 V minimum supply voltage. Its AC timing parameters-including 55 ns max access time-and DC characteristics (e.g., VIH = 2.2 V min, VOL = 0.4 V max) remain valid across the full 2.7–3.6 V range, making it suitable for systems powered by aging or discharged Li-ion batteries.
