Product details
Overview
R1WV3216RBG-7SI#B0 from Renesas Electronics is a 32Mb (2M × 16-bit) low-power static RAM with 70 ns access time, single 2.7–3.6 V supply, 4 µA typical standby current at 3.0 V, and data retention down to 2.0 V - designed for battery-backed memory systems in portable instrumentation and industrial control units.
For engineers reviewing the R1WV3216RBG-7SI#B0 datasheet, R1WV3216RBG-7SI#B0 pinout, R1WV3216RBG-7SI#B0 application, or R1WV3216RBG-7SI#B0 equivalent, this page delivers verified electrical specs, f-BGA package layout, byte-select capability, TTL-compatible I/O, and direct replacement guidance for legacy LPSRAM designs requiring zero-refresh operation and compact mounting area.
Technical Context
The R1WV3216RBG-7SI#B0 implements a stacked-micro-package architecture integrating two 16Mb Advanced LPSRAM dies in a single 48-ball fine-pitch BGA (7.5 mm × 8.5 mm, 0.75 mm pitch). It operates in word mode (A0–A20, DQ0–DQ15) or byte mode (A−1–A20, DQ0–DQ7) when enabled via BYTE# - though BYTE# is not supported on the f-BGA variant.
Memory control uses dual chip select (CS1#, CS2), independent upper/lower byte enables (UB#, LB#), write enable (WE#), and output enable (OE#) to support seamless memory expansion and OR-tie bus interfacing. All inputs/outputs are TTL-compatible with VIH ≥ 2.4 V and VIL ≤ 0.4 V under recommended operating conditions.

FAQ
What is the maximum access time specified for the R1WV3216RBG-7SI#B0?
The R1WV3216RBG-7SI#B0 has a maximum access time of 70 ns under recommended operating conditions (Vcc = 2.7–3.6 V, Ta = −40 °C to +85 °C). This value is guaranteed across the full industrial temperature range and applies to address-to-data valid timing (tAA) and chip-select-to-output-valid (tACS1/tACS2) parameters as defined in the AC characteristics table on page 8 of the datasheet.
Does the R1WV3216RBG-7SI#B0 support byte-mode operation?
No, the R1WV3216RBG-7SI#B0 does not support byte-mode operation. Although the R1WV3216R Series datasheet describes BYTE# functionality, that pin is only implemented on the 52-pin µTSOP variants (e.g., R1WV3216RSD-7S%). The f-BGA package (R1WV3216RBG-7SI#B0) omits the BYTE# pin and operates exclusively in 16-bit word mode using address lines A0–A20 and data lines DQ0–DQ15.
What is the minimum supply voltage required to retain data in the R1WV3216RBG-7SI#B0?
The R1WV3216RBG-7SI#B0 guarantees data retention down to 2.0 V (VDR = 2.0 V min), as specified in the Data Retention Characteristics table on page 14. At this voltage, the device draws ≤12 µA (typ.) at +25 °C and maintains stored data indefinitely - enabling robust operation during brown-out events or battery transitions without external backup capacitors.
Is the R1WV3216RBG-7SI#B0 pin-compatible with other members of the R1WV3216R family?
The R1WV3216RBG-7SI#B0 shares identical pinout and ball assignment with other 48-ball f-BGA variants in the R1WV3216R family (e.g., R1WV3216RBG-8S% and R1WV3216RBG-7S%), differing only in access time (70 ns vs. 85 ns) and temperature grade. It is not pin-compatible with the 52-pin µTSOP variants due to different package type, pin count, and presence/absence of BYTE#.
What are the key thermal and reliability qualifications for the R1WV3216RBG-7SI#B0?
The R1WV3216RBG-7SI#B0 is rated for industrial temperature operation (−40 °C to +85 °C) and conforms to Renesas' Standard quality grade per document colophon. It undergoes qualification per JEDEC JESD22-A108 for storage life and JESD22-A104 for temperature cycling. The f-BGA package supports reflow soldering per IPC/JEDEC J-STD-020, and the device is RoHS-compliant and halogen-free.
