Product details
Overview
RMLV0408EGSA-4S2#KA0 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 systems in industrial controllers and portable instrumentation.
For engineers reviewing the RMLV0408EGSA-4S2#KA0 datasheet, RMLV0408EGSA-4S2#KA0 pinout, RMLV0408EGSA-4S2#KA0 application, or RMLV0408EGSA-4S2#KA0 equivalent, key selection criteria include low-voltage data retention (1.5V min), TTL-compatible I/O, sTSOP-32 packaging, and guaranteed operation across –40°C to +85°C.
Technical Context
The RMLV0408EGSA-4S2#KA0 implements a fully static memory architecture with asynchronous parallel interface, featuring common bidirectional I/O lines (I/O0–I/O7), three-state output control via OE#, and chip-select–gated power management. Its address decoding supports full 19-bit addressing (A0–A18) for 512-kword capacity.
It uses Renesas's Advanced LPSRAM process to achieve simultaneous low active current (≤10mA ICC), ultra-low standby current (≤0.3µA ISB1 at 25°C), and robust data retention down to VCC = 1.5V - enabled by CS#-controlled retention mode and internal buffer isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4Mb (524,288 × 8-bit); provides sufficient buffer space for real-time firmware stacks or sensor log storage in edge nodes. |
| Supply voltage | 2.7V to 3.6V; compatible with 3.3V logic rails and tolerant of brown-out conditions during battery backup. |
| Access time | 45ns max; enables direct interfacing with legacy microcontrollers (e.g., Renesas RL78, SH-2) without wait states. |
| Standby current | 0.3µA typ. at 25°C; extends battery life to years in always-on monitoring devices with periodic wake-up. |
| Data retention VCC | 1.5V min; maintains SRAM contents during deep sleep or primary power loss while preserving system state. |
| Operating temperature | –40°C to +85°C; qualified for deployment in uncontrolled industrial enclosures and automotive under-hood auxiliary modules. |
| I/O interface | TTL-compatible inputs/outputs; eliminates level-shifter requirements when connected to 3.3V MCUs or FPGAs. |
Pinout & Package
Package: 32-pin sTSOP (8mm × 13.4mm, JEDEC MO-178AC), surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply | Primary 2.7–3.6V supply input; decoupling capacitor required within 5mm for noise immunity. |
| VSS | Ground | Digital ground reference; must be tied to system GND plane with low-inductance connection. |
| A0–A18 | Address inputs | 19-bit address bus supporting full 512-kword decoding; A18 is MSB for linear memory mapping. |
| I/O0–I/O7 | Bidirectional data bus | Common 8-bit data path; high-impedance when CS# = high or OE# = high, enabling bus sharing. |
| CS# | Chip select | Active-low enable; gates all internal buffers and controls entry into data retention mode when held high. |
| WE# | Write enable | Active-low write strobe; initiates write cycle only when CS# is also low; no internal latching. |
| OE# | Output enable | Active-low output control; places I/O pins in high-Z when deasserted, independent of CS# state. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply 3V operation | Eliminates dual-rail design complexity and reduces BOM count in portable and IoT edge devices. |
| 0.3µA standby current (typ.) | Enables >10-year battery life in coin-cell–powered applications such as smart meters and asset trackers. |
| 1.5V data retention threshold | Allows seamless transition to backup power without data loss during main supply interruption. |
| 45ns read/write cycle time | Supports deterministic timing in hard real-time systems where memory latency directly impacts control loop jitter. |
| sTSOP-32 package | Offers higher density than SOP/TSOP-II while maintaining compatibility with standard reflow profiles and AOI inspection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25616AL-10TLI | 256K × 16-bit (4Mb), 10ns access, 3.3V only, 48-pin TSOP-I | Higher speed but larger package and wider data bus; requires PCB redesign and bus-width adaptation. | Select if system demands sub-15ns latency and has routing margin for 48-pin layout. |
| AS6C4008-55ZIN | 512K × 8-bit (4Mb), 55ns access, 2.7–3.6V, 32-pin SOP | Slower access time and larger SOP footprint; lacks sTSOP thermal performance and board-area efficiency. | Select only if legacy SOP socket compatibility is mandatory and 55ns latency is acceptable. |
