Product details
Overview
R1WV6416RSA-5SI#S0 from Renesas Electronics is a 64Mb low-power static RAM organized as 4M word × 16-bit (or 8M word × 8-bit), fabricated in 0.15µm CMOS/TFT process, operating from a single 2.7–3.6V supply with 55 ns access time and −40°C to +85°C industrial temperature range, used for battery-backed memory in portable instrumentation and embedded control systems.
For engineers reviewing the R1WV6416RSA-5SI#S0 datasheet, R1WV6416RSA-5SI#S0 pinout, R1WV6416RSA-5SI#S0 application, or R1WV6416RSA-5SI#S0 equivalent, this page delivers verified specifications, TSOP(I) package layout, byte/word mode operation details, low-standby-current behavior, and direct alternatives for memory subsystem design and replacement planning.
Technical Context
The R1WV6416RSA-5SI#S0 implements a dual-bank 32Mb SRAM architecture with independent column decoders and shared address/control logic, supporting both word (16-bit) and byte (8-bit) data modes via BYTE# pin control. It uses TTL-compatible inputs and three-state outputs with OR-tie capability for bus sharing.
Its low-voltage operation enables direct integration with 3.3V microcontrollers and FPGAs, while the absence of clocks or refresh cycles simplifies timing-critical designs. Standby current drops to 8 µA at 3.0V, and data retention is guaranteed down to 2.0V VCC with tCDR = 0 ns and tR = 5 ms recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 64 Mbit (4,194,304 × 16 or 8,388,608 × 8), enabling compact high-density buffer storage without external multiplexing |
| Access time | 55 ns max (tAA, tACS1, tACS2, tBA), compatible with 18 MHz synchronous bus interfaces |
| Supply voltage | 2.7–3.6 V single rail, eliminating need for level shifters when interfacing with 3.3V logic families |
| Standby current | 8 µA typical at 3.0V/25°C, supporting >1-year battery life in always-on backup applications |
| Operating temperature | −40°C to +85°C (I-grade), qualified for industrial control, automotive infotainment head units, and outdoor telecom equipment |
| Package | 48-pin TSOP (I), 12 mm × 20 mm, 0.5 mm pitch - standard footprint for legacy PCB reuse and automated assembly |
| Data retention VCC | 2.0 V minimum, allowing reliable hold during brown-out or power-fail conditions without external capacitor hold-up |
Pinout & Package
48-pin plastic TSOP (I) package, 12 mm × 20 mm body, 0.5 mm pin pitch, normal-bend leads. Pin 1 marked by notch or dot; pins arranged in two parallel rows (24 per side).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address input (word mode) | 22-bit address bus supporting full 4M-word addressing; A-1 used only in byte mode for 8-bit access |
| DQ0–DQ15 | Data I/O bidirectional | Common 16-bit data bus; three-state outputs enable direct connection to shared system data lines |
| CS1#, CS2 | Chip select inputs | Two-level chip select hierarchy: CS1# active-low primary enable; CS2 active-high secondary control for bank selection or retention mode |
| WE#, OE#, LB#, UB# | Control inputs | WE# initiates writes; OE# enables reads; LB#/UB# select lower/upper byte lanes independently in 16-bit mode |

FAQ
What is the maximum access time specification for R1WV6416RSA-5SI#S0?
The R1WV6416RSA-5SI#S0 has a maximum access time of 55 ns for all key timing parameters including address access time (tAA), chip select access times (tACS1, tACS2), and byte enable access time (tBA). This value is guaranteed across the full −40°C to +85°C operating temperature range and 2.7–3.6V supply voltage, making R1WV6416RSA-5SI#S0 suitable for 18 MHz synchronous bus interfaces without wait states.
Does R1WV6416RSA-5SI#S0 support both 8-bit and 16-bit data bus configurations?
Yes, R1WV6416RSA-5SI#S0 supports both configurations via the BYTE# pin. When BYTE# is low, the device operates in byte mode (8-bit data width, using A-1 as LSB address); when high, it operates in word mode (16-bit data width). This dual-mode capability is confirmed for the 48-pin TSOP(I) package used by R1WV6416RSA-5SI#S0 and enables flexible hardware reuse across product variants without redesigning the memory interface.
What is the minimum supply voltage required to retain data in R1WV6416RSA-5SI#S0?
The R1WV6416RSA-5SI#S0 guarantees data retention down to 2.0 V VCC, as specified in the Low Vcc Data Retention Characteristics table. At this voltage, retention current (ICCDR) remains ≤160 µA at +85°C, and chip select to data retention time (tCDR) is 0 ns - meaning data is preserved immediately upon entering retention mode. This 2.0 V threshold is lower than many competing 64Mb SRAMs, enhancing reliability during deep brown-out events.
Is R1WV6416RSA-5SI#S0 pin-compatible with other members of the R1WV6416R Series?
Yes, R1WV6416RSA-5SI#S0 shares identical pinout and electrical characteristics with other 48-pin TSOP(I) variants in the R1WV6416R Series, including R1WV6416RSA-5SR#S0 (commercial grade) and R1WV6416RSA-7SI#S0 (70 ns speed grade). All share the same 48P3R footprint, address/data/control signal mapping, and power/ground pin locations, enabling drop-in replacement within the same package family for speed or temperature grade upgrades.
What is the typical standby current of R1WV6416RSA-5SI#S0 at 3.0V and 25°C?
The typical standby current of R1WV6416RSA-5SI#S0 is 8 µA at 3.0V and 25°C, as specified in the DC Characteristics table under ISB parameter. This value reflects center-of-distribution performance and is validated across production lots. At higher temperatures (e.g., +85°C), standby current rises to ≤100 µA, remaining well below 160 µA - confirming R1WV6416RSA-5SI#S0's suitability for thermally demanding industrial applications with strict power budgets.
