Product details
Overview
R1LV1616HBG-5SI#S0 from Renesas Electronics is a 16-Mbit static RAM organized as 1-Mword × 16-bit with embedded ECC, designed for low-power, wide-temperature battery-backed memory applications. It operates from a single 3.0 V supply (2.7–3.6 V), delivers 55 ns max access time, consumes only 1.5 µW typical standby current, and is housed in a 48-ball FBGA package.
For engineers reviewing the R1LV1616HBG-5SI#S0 datasheet, R1LV1616HBG-5SI#S0 pinout, R1LV1616HBG-5SI#S0 application, or R1LV1616HBG-5SI#S0 equivalent, this device serves as a drop-in SRAM replacement where ECC-enabled data integrity, extended temperature operation (−40°C to +85°C), and ultra-low standby power are required in industrial control, medical instrumentation, and backup memory subsystems.
Technical Context
This SRAM implements a fully static 6-transistor cell architecture with no clock or timing strobe required, enabling deterministic read/write timing and eliminating refresh overhead. Its dual chip select (CS1#, CS2) supports independent battery backup mode entry via either CS2 low or CS1# high/CS2 high conditions.
The device integrates dedicated ECC encoder/decoder logic that corrects all single-bit errors in real time during read operations and detects double-bit errors. Byte-level control (LB#, UB#) enables 8-bit sub-word access without external logic, while three-state I/O drivers support bus sharing in multi-device systems.
Key Specifications

|---|---|
| Memory density | 16 Mbit (1,048,576 words × 16 bits) - supports full 16-bit parallel data bus interface without external width expansion |
| Access time | 55 ns max - defines minimum cycle time for reliable random-access reads/writes at full speed |
| Supply voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and tolerant of brown-out conditions down to 2.7 V |
| Standby current | 0.5 µA typical - enables multi-year battery backup operation in non-volatile memory retention mode |
| ECC capability | Single-bit error correction / double-bit error detection - ensures data reliability in radiation-prone or long-term storage environments |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address input | 20-bit address bus supporting full 1-Mword addressing; A0–A19 directly map to internal row/column decoder |
| I/O0–I/O15 | Data input/output | 16-bit bidirectional data bus with three-state output drivers; shared for read and write transfers |

| LB#, UB# | Byte select | LB# enables lower byte (I/O0–I/O7); UB# enables upper byte (I/O8–I/O15) - supports 8-bit microcontroller interfaces without glue logic |
| VCC, VSS | Power and ground | Single 3.0 V supply domain; separate VCC/VSS pairs ensure stable core and I/O voltage reference |
| NU | No-connect test pin | Not used in normal operation; must be grounded or left open per datasheet - no functional role in application circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Fully static operation | No clocks, no refresh cycles - eliminates timing-critical system-level synchronization and reduces MCU firmware overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV1616AL-10TLI | 10 ns faster access (45 ns), no embedded ECC, same 48-pin TSOP-II package | Lacks hardware error correction; requires external ECC or software mitigation in safety-critical use | Select when maximum speed is prioritized over data integrity assurance and board layout allows TSOP-II footprint |
| AS6C1616-55TIN | Same 55 ns speed, no ECC, 44-pin SOJ package, higher standby current (5 µA typ) | SOJ packaging limits board density; absence of ECC increases validation burden for medical/industrial certifications | Choose only for legacy SOJ-compatible designs where FBGA rework is prohibitive and ECC is handled at system level |
Compared with IS61LV1616AL-10TLI and AS6C1616-55TIN, R1LV1616HBG-5SI#S0 uniquely delivers on-die ECC, ultra-low 0.5 µA standby, and FBGA packaging-making it the sole option among these three qualified for battery-backed, safety-aware, high-density embedded memory where data integrity cannot be compromised.

FAQ
What is the maximum operating frequency supported by R1LV1616HBG-5SI#S0?
R1LV1616HBG-5SI#S0 does not operate on a clock signal-it is a fully static RAM. Its maximum effective throughput is governed by its 55 ns access time and 55 ns cycle time, enabling up to ~18.2 MHz random read/write bandwidth in ideal conditions. The device requires no external clock, simplifying timing design in microcontroller- or FPGA-based systems.
Does R1LV1616HBG-5SI#S0 require external ECC circuitry?
No. R1LV1616HBG-5SI#S0 integrates a complete ECC engine that performs single-bit error correction and double-bit error detection transparently during every read operation. No external logic, software routines, or additional memory overhead is needed-ECC is implemented entirely within the R1LV1616HBG-5SI#S0 die.
How is battery backup mode activated on R1LV1616HBG-5SI#S0?
R1LV1616HBG-5SI#S0 enters battery backup mode through three independent hardware conditions: (1) CS2 driven low, (2) CS1# high AND CS2 high, or (3) LB# and UB# both high AND CS2 high AND CS1# low. Any of these configurations reduces current draw to ≤0.5 µA while retaining data, enabling seamless transition from main supply to backup power.
What is the function of the NU pin on R1LV1616HBG-5SI#S0?
The NU pin on R1LV1616HBG-5SI#S0 is a no-connect test pin with no functional role in normal operation. Per the datasheet, it must be either grounded (connected to VSS) or left unconnected (open). Leaving it floating is not permitted, but its state has no effect on R1LV1616HBG-5SI#S0 functionality or timing behavior.
Can R1LV1616HBG-5SI#S0 interface directly with an 8-bit microcontroller?
Yes. R1LV1616HBG-5SI#S0 supports byte-wide operation via dedicated LB# and UB# pins. An 8-bit microcontroller can access the lower byte (I/O0–I/O7) by asserting LB# low while holding UB# high, or the upper byte (I/O8–I/O15) by asserting UB# low while holding LB# high-no external demultiplexing logic is required.
