Product details
Overview
RMWV6416AGSA-5S2#AA0 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 is used in low-power embedded systems requiring non-volatile data retention during power loss.
For engineers reviewing the RMWV6416AGSA-5S2#AA0 datasheet, RMWV6416AGSA-5S2#AA0 pinout, RMWV6416AGSA-5S2#AA0 application, or RMWV6416AGSA-5S2#AA0 equivalent, this page delivers verified specifications, TSOP (I) package mapping, byte/word mode control logic, and direct alternatives for memory subsystem design and BOM optimization.
Technical Context
This SRAM implements dual chip select (CS1#, CS2), independent upper/lower byte control (UB#, LB#), and BYTE#-enabled mode selection between word and byte addressing-enabling flexible interface to 8-bit or 16-bit microcontrollers. Its low-voltage data retention down to 1.5V allows reliable hold-mode operation during brownout conditions.
The device uses Renesas' Advanced LPSRAM process to achieve 0.3mA max active current at 55ns cycle and 36µA max ISB1 standby current at +85°C, with TTL-compatible inputs/outputs and three-state DQ drivers supporting bus sharing without external buffers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64Mbit (4M × 16-bit or 8M × 8-bit configuration) |
| Access Time | 55ns max - defines minimum read cycle for timing-critical real-time buffering |
| Supply Voltage | 2.7V to 3.6V - compatible with 3.3V logic domains and battery-backed 3V rails |
| Standby Current | 1.2µA typ. at +25°C - enables multi-year battery life in always-on backup applications |
| Data Retention VCC | 1.5V min - maintains stored data during deep brownout or capacitor hold-up |
| Operating Temperature | –40°C to +85°C - qualified for industrial and automotive under-hood environments |
| Package | 48-pin TSOP (I), 12mm × 20mm - surface-mount compatible with standard reflow profiles |
Pinout & Package
RMWV6416AGSA-5S2#AA0 is housed in a 48-pin plastic TSOP (I) package (12mm × 20mm), pin-compatible with JEDEC MO-141AC. Pin functions support full parallel SRAM interfacing with separate byte enable, dual chip select, and address/data multiplexing via A-1 pin for byte-mode addressing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address input (word mode) | 22-bit address bus supporting 4M-word space; A-1 used only in byte mode |
| DQ0–DQ15 | Data input/output | 16-bit bidirectional data bus with three-state output control |
| CS1#, CS2 | Chip select inputs | CS1# active-low primary enable; CS2 high enables memory access and controls retention mode |
| OE#, WE# | Output/write enable | OE# gates read data output; WE# initiates write cycles with overlap timing requirements |
| UB#, LB# | Byte select | Independent control of upper (DQ8–DQ15) and lower (DQ0–DQ7) data bytes |
| BYTE# | Mode control | Selects word mode (BYTE# = VIH) or byte mode (BYTE# = VIL); supported only on TSOP (I) and µTSOP (II) |
| VCC, VSS | Power/Ground | Single 3V supply rail; two VSS pins provide dedicated ground return paths |
Key Features
| Feature | Design Value |
|---|---|
| Battery backup operation | Retains data at VCC ≥ 1.5V with ≤36µA current at +85°C - eliminates need for external backup controllers |
| Direct TTL compatibility | All inputs and outputs meet TTL voltage thresholds (VIH ≥ 2.2V, VOL ≤ 0.4V) - interfaces directly to legacy 3.3V microcontrollers without level shifters |
| Low-power standby | 1.2µA typical ISB1 at +25°C - reduces system quiescent power in sleep modes |
| Flexible data width | Configurable 8-bit or 16-bit operation via BYTE# pin - simplifies migration between MCU families with differing bus widths |
| Common I/O architecture | Single DQ bus for read/write with three-state output - reduces PCB trace count and simplifies layout versus separate I/O pins |

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 |
|---|---|---|---|
| ISSI IS61WV6416BLL-55TLI | 55ns access, same 4M×16 organization, but 44-pin TSOP (II) package and no BYTE# pin | Lacks byte/word mode switching; requires fixed 16-bit bus interface | Choose when board layout already accommodates 44-pin TSOP and byte-mode flexibility is unnecessary |
| Cypress S7R6416A55ZI020 | Same 48-pin TSOP (I), 55ns access, but higher 5µA typical standby current and no low-VCC retention spec below 2.0V | Not suitable for extended battery-hold applications below 2.0V | Prefer when cost sensitivity outweighs ultra-low standby or deep brownout retention needs |
Compared with IS61WV6416BLL-55TLI and S7R6416A55ZI020, RMWV6416AGSA-5S2#AA0 uniquely combines byte/word mode configurability, 1.5V data retention, and 1.2µA standby - making it optimal for battery-constrained, mixed-bus-width designs requiring guaranteed data integrity during extended power loss.

FAQ
What is the maximum operating temperature range for RMWV6416AGSA-5S2#AA0?
RMWV6416AGSA-5S2#AA0 is rated for continuous operation from –40°C to +85°C, meeting industrial temperature grade requirements. This range is validated per the Absolute Maximum Ratings and DC Operating Conditions tables in the R10DS0278EJ0200 Rev.2.00 datasheet, with all AC and DC parameters guaranteed across this span.
Does RMWV6416AGSA-5S2#AA0 support true 8-bit operation?
Yes, RMWV6416AGSA-5S2#AA0 supports true 8-bit operation via its BYTE# pin: when BYTE# is driven low, the device enters byte mode and uses A-1 as an address bit, enabling 8M-word × 8-bit addressing. This is confirmed in the Pin Description and Operation Table sections of the datasheet.
What is the minimum VCC required to retain data in RMWV6416AGSA-5S2#AA0?
The minimum VCC for data retention in RMWV6416AGSA-5S2#AA0 is 1.5V, as specified in the Low VCC Data Retention Characteristics table. At this voltage, the device maintains stored data with ICCDR ≤ 36µA at +85°C, provided CS2 ≤ 0.2V or equivalent retention entry conditions are met.
Is RMWV6416AGSA-5S2#AA0 pin-compatible with other packages in the RMWV6416A family?
No, RMWV6416AGSA-5S2#AA0 uses a 48-pin TSOP (I) package and is not pin-compatible with the 52-pin µTSOP (II) or 48-ball FBGA variants. While functionally identical, pin counts, layouts, and ball/pad assignments differ - requiring separate PCB footprints for each package type.
Can RMWV6416AGSA-5S2#AA0 be used with 5V-tolerant microcontrollers?
No, RMWV6416AGSA-5S2#AA0 operates strictly from 2.7V to 3.6V and is not 5V-tolerant. Its inputs require VIH ≥ 2.2V and VIL ≤ 0.6V, and applying 5V signals risks permanent damage. Interface with 5V systems requires level translation or use of 3.3V-compatible MCUs.
