Product details
Overview
R1LV1616HSA-5SI#S1 from Renesas Electronics is a 16-Mbit static RAM organized as 1-Mword × 16-bit or 2-Mword × 8-bit with embedded ECC, operating from a single 3.0 V supply (2.7–3.6 V), featuring 55 ns max access time, 1.5 µW typical standby current, and wide temperature range (−40 to +85°C) for industrial battery-backed systems.
For engineers reviewing the R1LV1616HSA-5SI#S1 datasheet, R1LV1616HSA-5SI#S1 pinout, R1LV1616HSA-5SI#S1 application, or R1LV1616HSA-5SI#S1 equivalent, key selection factors include byte/word mode flexibility, dual chip select for battery backup, TSOP-48 packaging, ECC-enabled data integrity, and low-power retention down to 1.5 V.
Technical Context
This SRAM implements a fully static 6-transistor memory cell architecture with no clock or timing strobe required, supporting equal read/write cycle times and three-state bidirectional I/Os. Its control logic handles independent upper/lower byte enables (UB#/LB#) and byte-mode addressing via A-1 and BYTE#, enabling seamless x8/x16 interface adaptation.
The embedded ECC circuitry performs real-time single-bit error correction and detection during read operations without external logic, while dual chip select inputs (CS1#, CS2) allow hierarchical power management-CS2 enables low-voltage data retention mode at VCC ≥ 1.5 V, supporting battery backup operation with ICCDR ≤ 8 µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 16 Mbit (1-Mword × 16-bit or 2-Mword × 8-bit) |

| WE#, OE#, LB#, UB#, BYTE# | Control inputs | Independent write enable, output enable, byte masking, and mode selection for flexible bus interfacing |
| VCC, VSS | Power and ground | Single 3.0 V supply domain; decoupling required per JEDEC TSOP-48 layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC | Hardware-accelerated single-bit error correction on every read, eliminating software overhead and system-level CRC checks |

FAQ
What is the maximum access time specified for R1LV1616HSA-5SI#S1?
The R1LV1616HSA-5SI#S1 has a maximum access time of 55 ns, measured as address access time (tAA), chip select access time (tACS1/tACS2), and read cycle time (tRC). This value is guaranteed over the full industrial temperature range (−40°C to +85°C) and supply voltage range (2.7–3.6 V), making it suitable for deterministic real-time control loops requiring predictable memory latency.
Does R1LV1616HSA-5SI#S1 support both 8-bit and 16-bit data bus configurations?
Yes, R1LV1616HSA-5SI#S1 supports both configurations: 1-Mword × 16-bit (using A0–A19) and 2-Mword × 8-bit (using A-1–A19 with BYTE# asserted low). The A-1 address line and BYTE# pin enable runtime selection between modes, allowing the same R1LV1616HSA-5SI#S1 device to interface with either 8-bit or 16-bit microcontrollers without hardware changes.
How does the embedded ECC in R1LV1616HSA-5SI#S1 operate?
The embedded ECC in R1LV1616HSA-5SI#S1 performs automatic single-bit error correction and detection on every read operation using dedicated on-die encoder/decoder circuitry. No external logic or software intervention is required-the R1LV1616HSA-5SI#S1 transparently corrects bit flips caused by EMI or alpha particles and flags uncorrectable multi-bit errors, ensuring data integrity in mission-critical applications.
What is the lowest supply voltage at which R1LV1616HSA-5SI#S1 retains stored data?
R1LV1616HSA-5SI#S1 retains valid data down to 1.5 V, as specified in its low-VCC data retention characteristics. In retention mode-activated by asserting CS2 low or configuring CS1# and LB#/UB# per datasheet conditions-the device draws ≤8 µA and maintains memory contents without refresh, enabling reliable operation during brown-out or battery switchover events.
Is R1LV1616HSA-5SI#S1 compatible with standard 48-pin TSOP-I footprints?
Yes, R1LV1616HSA-5SI#S1 uses a standard 48-pin plastic TSOPI package (12 × 20 mm, 0.5 mm pitch) with pinout conforming to JEDEC MO-147AB. It is mechanically and electrically compatible with common TSOP-I sockets and PCB land patterns, allowing drop-in replacement in existing designs using equivalent-density SRAMs in the same package outline.
