Product details
Overview
RMWV6416AGBG-5S2#AC0 from Renesas Electronics is a 64Mb Advanced LPSRAM organized as 4,194,304-word × 16-bit (or 8,388,608-word × 8-bit), operating from a single 2.7–3.6V supply with 55ns max access time and 1.2µA typical standby current at +25°C. It supports battery backup operation and delivers TTL-compatible I/O for embedded memory subsystems in portable industrial controllers.
For engineers reviewing the RMWV6416AGBG-5S2#AC0 datasheet, RMWV6416AGBG-5S2#AC0 pinout, RMWV6416AGBG-5S2#AC0 application, or RMWV6416AGBG-5S2#AC0 equivalent, this page provides verified package mapping, byte/word mode control logic, low-voltage data retention behavior, and direct alternatives for SRAM replacement in space-constrained, low-power designs.
Technical Context
The RMWV6416AGBG-5S2#AC0 implements dual chip-select architecture (CS1# active-low, CS2 active-high) with independent upper/lower byte enable (UB#/LB#) and output enable (OE#), enabling selective 8-bit or full 16-bit data transfers without external gating. Its BYTE# pin is internally fixed to high (word mode), eliminating external configuration for 16-bit bus interfaces.
It features three-state bidirectional DQ0–DQ15 I/O with 2.4V VOH (at -1mA) and 0.4V VOL (at 2mA), and supports low-VCC data retention down to 1.5V using CS2 ≤ 0.2V, CS1# ≥ VCC−0.2V, or simultaneous LB#/UB# ≥ VCC−0.2V - all validated across −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64Mbit (4M × 16-bit or 8M × 8-bit), enabling compact buffer storage in microcontroller co-processor systems |
| Access Time | 55ns max - guarantees deterministic read latency for real-time control loops running at ≤18MHz bus clock |
| Supply Voltage | 2.7V to 3.6V - compatible with standard 3.3V rails and tolerant of brown-out conditions during battery switchover |
| Standby Current | 1.2µA typ. at +25°C - extends battery life beyond 10 years in always-on backup mode (e.g., RTC + configuration SRAM) |
| Data Retention VCC | 1.5V min - maintains stored values during deep sleep or main power loss without external keep-alive circuitry |
| Operating Temperature | −40°C to +85°C - qualified for industrial automation, transportation, and outdoor edge-node deployments |
| I/O Compatibility | TTL-level inputs and outputs - eliminates level-shifting requirements when interfacing with legacy MCU GPIO or FPGA I/O banks |
Pinout & Package
RMWV6416AGBG-5S2#AC0 uses a 48-ball fine-pitch ball grid array (FBGA) package with 0.75mm ball pitch, footprint size 8.0mm × 10.5mm, and RoHS-compliant matte tin finish. The package supports automated reflow assembly and offers superior thermal dissipation vs. TSOP variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| DQ0–DQ15 | Data input/output | 16-bit bidirectional data bus with three-state control; no external bus transceivers required |
| CS1#, CS2 | Chip select inputs | CS1# active-low + CS2 active-high enables hierarchical memory decoding in multi-chip systems |
| WE#, OE#, UB#, LB# | Control inputs | Independent write enable, output enable, and byte-lane selection allow granular 8-bit writes without masking logic |
| VCC, VSS | Power and ground | Dual VCC/VSS pairs reduce switching noise; decoupling recommended per Renesas layout guidelines |
| NC | No connection | Balls B1, C1, D1, E1, F1, G1, H1, A2, A3, A4, A5, A6, A7, A8, A9, A10, A11, A12, A13, A14, A15, A16, A17, A18, A19, A20, A21, A22, A23, A24 - no internal connection; must be left unconnected or grounded per PCB design rules |
Key Features
| Feature | Design Value |
|---|---|
| Advanced LPSRAM technology | Enables 64Mbit density in FBGA while maintaining 55ns access - 30% smaller footprint than equivalent TSOP-I devices |
| Low-voltage data retention | Retains data at VCC = 1.5V using CS2 ≤ 0.2V, reducing backup power supply complexity in battery-critical applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-density, low-power SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-55ZSXIT | 55ns access, 64Mb (4M×16), 2.2–3.6V supply, 48-ball FBGA (8×10mm), but 5µA standby current (typ.) at +25°C | Higher standby draw limits battery lifetime in always-on backup; lacks low-VCC retention below 2.0V | Select only if system already uses Cypress memory IP and requires identical timing margins with relaxed power constraints |
| IS61WV6416BLL-55NLI | 55ns access, 64Mb (4M×16), 2.5–3.6V supply, 48-pin TSOP-I (12×20mm), 2µA standby (typ.), no FBGA option | Larger footprint increases PCB area by 2.3×; no low-VCC retention mode; incompatible with fine-pitch SMT lines | Choose only for legacy board refresh where TSOP socket reuse is mandatory and volume production prioritizes cost over size/power |
Compared with CY62167EV30LL-55ZSXIT and IS61WV6416BLL-55NLI, the RMWV6416AGBG-5S2#AC0 uniquely combines 48-ball FBGA miniaturization, 1.2µA standby, and 1.5V data retention - making it the sole option for new designs targeting <10mm² memory footprint and >5-year battery life in industrial edge nodes.

FAQ
What is the pin compatibility status of RMWV6416AGBG-5S2#AC0 with other RMWV6416A variants?
The RMWV6416AGBG-5S2#AC0 shares identical logic functionality and AC/DC specifications with RMWV6416AGSA-5S2 (TSOP-I) and RMWV6416AGSD-5S2 (μTSOP-II), but its 48-ball FBGA pinout is physically incompatible. Address, data, and control signals map to different ball positions; PCB redesign is required for migration. No pin-to-pin replacement exists across package types.
Does RMWV6416AGBG-5S2#AC0 support byte-mode operation?
No. The RMWV6416AGBG-5S2#AC0 fixes BYTE# internally to high (word mode), disabling byte-mode addressing. This is confirmed in the datasheet's Pin Description table and Operation Table notes, which state "BYTE# pin supported by only 48pin TSOP (I) and 52pin µTSOP (II) types" - meaning FBGA variants operate exclusively in 16-bit word mode with A0–A21 addressing.
What is the minimum VCC required to retain data in RMWV6416AGBG-5S2#AC0 during power loss?
The RMWV6416AGBG-5S2#AC0 retains data down to VCC = 1.5V when placed in retention mode via CS2 ≤ 0.2V, CS1# ≥ VCC−0.2V, or simultaneous LB#/UB# ≥ VCC−0.2V. This is specified in the Low VCC Data Retention Characteristics table (Page 13) and validated across the full −40°C to +85°C temperature range.
How does the standby current of RMWV6416AGBG-5S2#AC0 scale with temperature?
Standby current (ISB1) increases with temperature: 1.2µA typ. at +25°C, 2µA typ. at +40°C, 24µA max at +70°C, and 36µA max at +85°C. These values are measured under defined bias conditions (CS2 ≤ 0.2V or LB#/UB# ≥ VCC−0.2V) and reflect leakage growth in advanced LPSRAM cells - critical for thermal design of sealed enclosures.
Can RMWV6416AGBG-5S2#AC0 be used with a 2.5V supply?
No. The absolute minimum supply voltage for RMWV6416AGBG-5S2#AC0 is 2.7V, as stated in the DC Operating Conditions table (Page 4). Operation below 2.7V violates specification and may cause data corruption, timing violations, or failure to enter retention mode - 2.5V systems require voltage translation or alternative SRAMs rated for 2.3–2.7V operation.
