Product details
Overview
R1WV6416RBG-5SI#B0 from Renesas Electronics is a 64Mb low-power static RAM (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 55ns access time and 8µA typical standby current at 3.0V. It supports battery-backed memory applications requiring zero-refresh operation, TTL-compatible interfacing, and flexible byte/word addressing via LB#/UB#/BYTE# control.
For engineers reviewing the R1WV6416RBG-5SI#B0 datasheet, R1WV6416RBG-5SI#B0 pinout, R1WV6416RBG-5SI#B0 application, or R1WV6416RBG-5SI#B0 equivalent, this device delivers deterministic SRAM timing without clocks or refresh cycles, supports multi-chip expansion via CS1#/CS2#, and provides OR-tie capable three-state I/O for bus sharing in embedded controllers, industrial HMIs, and portable instrumentation.
Technical Context
The R1WV6416RBG-5SI#B0 implements a dual-bank 32Mb SRAM architecture with independent column decoders and sense/write amplifiers, enabling simultaneous access to two 32Mb blocks. Its address buffer, WE#/OE#/CS logic, and DQ selector are fully static, supporting asynchronous read/write cycles with tRC = 55ns and tAA = 55ns under Vcc = 2.7–3.6V and Ta = –40°C to +85°C.
It features dual chip-select architecture (CS1# active-low, CS2 active-high), byte-select capability via LB#/UB#, and optional BYTE#-controlled mode switching between word and byte addressing. Data retention is guaranteed down to Vcc = 2.0V with ICCDR ≤ 160µA at +85°C, and all inputs/outputs meet TTL voltage thresholds (VIH ≥ 2.4V, VIL ≤ 0.4V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-55ZSXI | 55ns access, 64Mb (4M×16), 2.2–3.6V supply, 25-ball BGA (smaller footprint but no BYTE# pin) | Lacks BYTE#-controlled byte/word mode switching; requires fixed-width bus design | Prefer when board space is critical and byte-mode operation is unnecessary |
| IS61WV6416BLL-55NLI | 55ns access, 64Mb (4M×16), 2.5–3.6V supply, 48-pin TSOP-I package (not BGA) | TSOP-I package increases PCB area and limits routing density; same functional set otherwise | Choose when legacy through-hole or reflow-compatible TSOP assembly is mandated |
Compared with CY62167EV30LL-55ZSXI and IS61WV6416BLL-55NLI, the R1WV6416RBG-5SI#B0 uniquely combines f-BGA miniaturization, BYTE#-enabled mode flexibility, and industrial temperature support - making it optimal for next-generation portable test gear and battery-constrained edge nodes where both size and interface adaptability matter.

FAQ
What is the operating voltage range for the R1WV6416RBG-5SI#B0?
The R1WV6416RBG-5SI#B0 operates from a single 2.7V to 3.6V supply. It maintains full functionality-including 55ns access time and TTL-compatible I/O levels-across this range. Data retention is guaranteed down to 2.0V, enabling reliable operation during brown-out conditions or battery backup scenarios. The device draws ≤160µA standby current at +85°C when Vcc ≥ 2.0V.
Does the R1WV6416RBG-5SI#B0 support byte-wide and word-wide data access?
Yes, the R1WV6416RBG-5SI#B0 supports both modes. When BYTE# is high, it operates in 16-bit word mode (A0–A21 addressing 4M words). When BYTE# is low, it switches to 8-bit byte mode using A–1 as the LSB (A0–A21 addressing 8M bytes). This dual-mode capability is confirmed in the Operation Table (page 5) and applies to the f-BGA package variant per datasheet footnote.
What is the pin count and package type of the R1WV6416RBG-5SI#B0?
The R1WV6416RBG-5SI#B0 uses a 48-ball fine-pitch ball grid array (f-BGA) package with 0.75 mm pitch. Its mechanical outline matches JEDEC MO-245AC, measuring approximately 10.5 mm × 10.5 mm. Pin assignments follow the top-view layout shown on page 2 of the datasheet, including dedicated address, data, control, and power balls - with NC balls explicitly marked.
How does the R1WV6416RBG-5SI#B0 handle low-power standby operation?
The R1WV6416RBG-5SI#B0 achieves ultra-low standby current (8 µA typical at 3.0V, ≤160 µA at +85°C) by disabling internal buffers and sense amplifiers when CS2 is driven low or CS1# is high. Standby entry is controlled solely by chip-select signals-no command sequence or register programming is required. This behavior is validated in the DC Characteristics table (page 6) and Low Vcc Data Retention section (page 15).
Is the R1WV6416RBG-5SI#B0 pin-compatible with other members of the R1WV6416R family?
No-pin compatibility is package-dependent. The R1WV6416RBG-5SI#B0 (48-ball f-BGA) has a different pinout than the TSOP-I (48-pin) or µTSOP-II (52-pin) variants. While electrical functionality (addressing, control logic, timing) is consistent across the family, ball/pin assignments-including Vcc/Vss placement and NC locations-differ. Layout reuse requires package-specific footprint verification against the respective pin arrangement diagram.
