Product details
Overview
RMLV0408EGSA-4S2#AA0 from Renesas Electronics is a 4Mb advanced low-power static RAM organized as 524,288-word × 8-bit, operating from a single 2.7–3.6V supply, with 45ns max access time and 0.3µA typical standby current, designed for battery-backed memory in industrial control and portable instrumentation.
For engineers reviewing the RMLV0408EGSA-4S2#AA0 datasheet, RMLV0408EGSA-4S2#AA0 pinout, RMLV0408EGSA-4S2#AA0 application, or RMLV0408EGSA-4S2#AA0 equivalent, key selection criteria include sTSOP-32 package compatibility, TTL-level I/O interface, low-voltage data retention down to 1.5V, and guaranteed operation across –40°C to +85°C.
Technical Context
This device implements a fully asynchronous SRAM architecture with common I/O bus, three-state output control via OE#, and chip-select–gated power management. Its timing model enforces equal read/write cycle times (tRC = tWC = 45ns max), and supports direct TTL interfacing without level-shifting.
The memory matrix uses a 19-bit address space (A0–A18) decoded into 2,048 × 2,048 rows/columns, with internal timing pulse generation ensuring deterministic setup/hold margins - including tAS = 0ns address setup and tDH = 0ns data hold during write cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4Mb (524,288 × 8-bit); supports byte-wide data paths without external multiplexing |
| Supply voltage | 2.7–3.6V; enables direct integration with 3.3V logic domains and battery backup systems |
| Access time | 45ns max; ensures compatibility with legacy microcontrollers and FPGAs requiring ≤45ns SRAM response |
| Standby current | 0.3µA typ. at +25°C; extends battery life in always-on backup mode beyond 10 years |
| Data retention VCC | 1.5V min; maintains stored data during brown-out or deep-sleep states without external regulators |
| Operating temperature | –40°C to +85°C; qualified for industrial-grade embedded systems without derating |

Pinout & Package
Package: 32-pin sTSOP (8mm × 13.4mm), surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply | Primary 2.7–3.6V supply rail; decoupling required within 5mm of pin |
| VSS | Ground | System reference ground; must be connected to low-impedance PCB plane |
| A0–A18 | Address input | 19-bit unidirectional address bus; A0 = LSB, A18 = MSB; no internal latching |
| I/O0–I/O7 | Data input/output | Bi-directional 8-bit data bus with three-state control; shared pins reduce PCB trace count |
| CS# | Chip select | Active-low enable; gates all internal functions and controls data retention entry when high |
| WE# | Write enable | Active-low write strobe; initiates write on falling edge when CS# is active |
| OE# | Output enable | Active-low output control; places I/O pins in high-Z when inactive, independent of CS# state |
Key Features
| Feature | Design Value |
|---|---|
| Low-power standby | 0.3µA typical current draw enables multi-year battery backup without periodic refresh |
| Single-supply operation | Eliminates dual-rail design complexity and reduces BOM cost versus 5V/3.3V mixed systems |
| Equal access/cycle timing | 45ns tRC = tWC simplifies timing budgeting in synchronous and asynchronous controller interfaces |
| Direct TTL compatibility | VIH = 2.2V min / VIL = 0.6V max allows seamless connection to legacy 3.3V microcontrollers |
| Low-VCC data retention | Maintains valid data at 1.5V supply, supporting ultra-low-power sleep modes in portable equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25616AL-10TLI | 256K × 16-bit organization, 10ns access, 3.3V-only supply (3.135–3.465V) | Higher density per pin but wider bus; incompatible address/data pinout and faster timing | Select only if system requires 16-bit data path and can support tighter timing margins and narrower voltage window |
| AS6C4008-55ZIN | 4Mb × 8-bit, 55ns access, 2.7–3.6V supply, 32-pin SOP package | Same memory map and voltage range, but slower speed and larger SOP footprint vs. sTSOP | Choose when board layout prioritizes through-hole or SOP compatibility over speed and space efficiency |
