Product details

Overview

R1WV6416RBG-5SR#B0 from Renesas Electronics is a 64Mb low-power static RAM organized as 4,194,304 × 16-bit or 8,388,608 × 8-bit, fabricated in 0.15µm CMOS/TFT process. It operates from a single 2.7–3.6V supply, delivers 55ns access time, and draws only 8µA standby current at 3.0V - enabling battery-backed memory retention in portable instrumentation and industrial control modules.

For engineers reviewing the R1WV6416RBG-5SR#B0 datasheet, R1WV6416RBG-5SR#B0 pinout, R1WV6416RBG-5SR#B0 application, or R1WV6416RBG-5SR#B0 equivalent, this device serves as a drop-in replacement for legacy LPSRAMs requiring TTL-compatible I/O, no-refresh operation, and flexible byte/word addressing in space-constrained f-BGA layouts.

Technical Context

The R1WV6416RBG-5SR#B0 implements dual-memory-array architecture (two 32Mb blocks) with independent column decoders and sense/write amplifiers. Its control logic supports three operational modes - word (16-bit), byte (8-bit), and extended byte (A−1 addressing) - selected via BYTE#, LB#, and UB# pins.

It uses asynchronous interface timing with four distinct chip-select configurations (CS1#/CS2 combinations) to enable stand-by, read, write, and output-disable states. Standby entry requires either CS2 ≤ 0.2V or CS1# ≥ VCC−0.2V with CS2 ≥ VCC−0.2V, ensuring deterministic low-power entry without external sequencing.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (4M × 16 or 8M × 8 configuration)
Access Time	55 ns - guarantees sub-18 MHz bus timing compatibility with legacy microcontrollers
Supply Voltage	2.7–3.6 V - supports direct connection to Li-ion battery rails and 3.3V system supplies
Standby Current	8 µA typical at 3.0V - enables >1-year data retention on coin-cell backup
Package	f-BGA, 48-ball, 0.75mm pitch - reduces PCB area by 42% vs. TSOP(I) and enables high-density routing
I/O Interface	TTL-compatible inputs/outputs - eliminates level-shifter requirements in 3.3V logic systems
Data Retention V_CC	2.0–3.6 V - maintains stored data during brown-out or battery-switchover events

Pinout & Package

f-BGA package: 48-ball grid array, 0.75mm pitch, 8mm × 9.2mm body size (JEDEC MO-245 compliant). Ball layout optimized for signal integrity with dedicated V_CC/V_SS pairs adjacent to I/O banks.

Pin/Terminal	Circuit Role	Design Meaning

DQ0–DQ15	Data I/O bidirectional	16-bit common bus with three-state outputs; OR-tie capable for multi-SRAM expansion
CS1#, CS2	Chip select inputs	Two-level hierarchical selection: CS1# active-low primary, CS2 active-high secondary for bank isolation
WE#, OE#, LB#, UB#	Control inputs	Asynchronous write/read strobes with byte masking; LB#/UB# define 8-bit access windows
BYTE#	Mode select input	Enables byte-addressing mode (A−1 valid); supported only in TSOP/µTSOP packages - not connected in f-BGA variant
V_CC, V_SS	Power/Ground	Dual V_CC/V_SS pairs per quadrant minimize switching noise and improve IR drop margin

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-power static RAM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IS61WV6416BLL-10MLI	10ns slower access (65ns), 48-pin TSOP(I) only, 15mA max operating current	Lacks f-BGA option; higher ICC2 limits use in ultra-low-power battery systems	Select when board redesign is impractical and 65ns timing suffices
AS6C6416-55PCN	Same 55ns speed but 3.3V-only supply (3.135–3.465V), no 2.7V operation	Incompatible with wide-input-range battery systems; no data retention below 3.135V	Choose only for fixed 3.3V rail designs where voltage tolerance is guaranteed

Compared with IS61WV6416BLL-10MLI and AS6C6416-55PCN, the R1WV6416RBG-5SR#B0 uniquely combines 55ns speed, 2.7–3.6V operation, 8µA standby, and f-BGA packaging - making it the sole option for compact, battery-resilient, wide-voltage embedded memory subsystems.

FAQ

What is the operating temperature range for R1WV6416RBG-5SR#B0?

The R1WV6416RBG-5SR#B0 is rated for commercial temperature operation from 0°C to +70°C (R-grade). This is confirmed in the Ordering Information table on page 1 of REJ03C0368-0100, where the "R" suffix denotes the 0~+70°C range. The device does not support industrial (-40°C to +85°C) operation - that variant uses the "I" suffix (e.g., R1WV6416RBG-5SI#B0).

Does R1WV6416RBG-5SR#B0 support byte-mode addressing?

No, R1WV6416RBG-5SR#B0 does not support byte-mode addressing. The BYTE# pin is explicitly unsupported in the f-BGA package per Pin Description (page 3) and Block Diagram (page 4) of REJ03C0368-0100. Byte-mode functionality is only available on the 48-pin TSOP(I) and 52-pin µTSOP(II) variants. The R1WV6416RBG-5SR#B0 operates exclusively in 16-bit word mode.

What is the maximum data retention voltage for R1WV6416RBG-5SR#B0?

The R1WV6416RBG-5SR#B0 guarantees data retention down to 2.0V V_CC, as specified in the Low Vcc Data Retention Characteristics table (page 15) of REJ03C0368-0100. At voltages between 2.0V and 3.6V, the device retains stored data indefinitely while drawing ≤160µA at +85°C - enabling robust operation during brown-out conditions or capacitor-based backup.

Is R1WV6416RBG-5SR#B0 pin-compatible with other R1WV6416R series variants?

No, R1WV6416RBG-5SR#B0 is not pin-compatible with TSOP or µTSOP variants. Its 48-ball f-BGA footprint (0.75mm pitch) differs fundamentally from the 48-pin TSOP(I) (0.5mm pitch, 12×20mm) and 52-pin µTSOP(II) (0.4mm pitch, 10.79×10.49mm) packages. Pin assignments also differ - notably, BYTE# is NC in f-BGA but functional in TSOP/µTSOP. Migration requires PCB redesign.

What is the meaning of the "#B0" suffix in R1WV6416RBG-5SR#B0?

The "#B0" suffix in R1WV6416RBG-5SR#B0 indicates tape-and-reel packaging per Renesas standard ordering nomenclature (page 1, Ordering Information). "B0" denotes bulk packaging in embossed carrier tape, 1,000 units per reel - consistent with Renesas's packaging codes for f-BGA devices in the R1WV6416R family.
