Product details
Overview
RMLV0408EGSP-4S2#HA1 from Renesas Electronics is a 4Mb Advanced LPSRAM 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. It supports battery backup systems via low-voltage data retention down to 1.5V and features three-state bidirectional I/Os compatible with TTL logic levels.
For engineers reviewing the RMLV0408EGSP-4S2#HA1 datasheet, RMLV0408EGSP-4S2#HA1 pinout, RMLV0408EGSP-4S2#HA1 application, or RMLV0408EGSP-4S2#HA1 equivalent, this device is selected for embedded systems requiring non-volatile SRAM behavior under power loss, deterministic timing in real-time controllers, and minimal quiescent power in portable instrumentation.
Technical Context
The RMLV0408EGSP-4S2#HA1 implements a synchronous static RAM architecture with full address/data multiplexing eliminated-address inputs A0–A18 and bidirectional data I/O0–I/O7 operate independently. Chip select (CS#), write enable (WE#), and output enable (OE#) control logic ensures strict read/write cycle separation and high-impedance output disable during standby.
Its Advanced LPSRAM process enables sub-1µA standby current at +25°C while maintaining 45ns access and cycle times across -40°C to +85°C. Data retention is guaranteed at VCC ≥ 1.5V with CS# held high, enabling seamless integration into battery-backed memory subsystems without external supervision circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4Mb (524,288 × 8-bit); provides sufficient buffer space for firmware stacks or sensor data logging in resource-constrained microcontrollers. |
| Supply voltage | 2.7V–3.6V; compatible with standard 3.3V logic rails and tolerant of brown-out conditions down to 2.7V without functional loss. |
| Access time | 45ns (max); enables direct interface with legacy 22-MHz bus controllers or modern MCUs using wait-state-free burst reads. |
| Standby current | 0.3µA (typ. at +25°C); reduces annual battery drain to <1.5µAh in always-on backup mode, extending coin-cell life beyond 10 years. |
| Data retention VCC | 1.5V min; allows retention during deep sleep or main power failure while preserving contents without external capacitor hold-up. |
| Operating temperature | -40°C to +85°C; qualified for industrial automation, automotive body control modules, and outdoor telemetry equipment. |
| I/O voltage compatibility | TTL-compatible inputs/outputs (VIH = 2.2V min, VOL = 0.4V max @ 2.1mA); eliminates level-shifter requirements in mixed-voltage designs. |
Pinout & Package
Package: 525-mil 32-pin plastic SOP (Small Outline Package), surface-mount, gull-wing lead form, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply | Primary 2.7–3.6V supply input; requires local 0.1µF ceramic decoupling adjacent to pin. |
| VSS | Ground | Digital ground reference; must be connected to system ground plane with low-inductance path. |
| A0–A18 | Address inputs | 19-bit address bus supporting full 524,288-word addressing; no internal address latching-must be stable before CS# active. |
| I/O0–I/O7 | Bidirectional data bus | 8-bit common I/O port with three-state control; driven only when CS# and OE# are low (read) or CS# and WE# are low (write). |
| CS# | Chip select | Active-low enable controlling all internal buffers; high state forces I/Os into high-Z and reduces current to standby level. |
| WE# | Write enable | Active-low signal qualifying write cycles; must overlap low CS# to initiate data latch into memory array. |
| OE# | Output enable | Active-low control for output drivers only; does not affect write functionality or standby current when CS# is high. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply 3V operation | Eliminates dual-rail design complexity and reduces BOM count by removing separate VDDQ/VDD logic rails. |
| 45ns equal access/cycle timing | Enables predictable bus arbitration and simplifies timing margin analysis in synchronous controller interfaces. |
| 0.3µA standby current (typ.) | Permits use in energy-harvesting or battery-only systems where average power budget is <1µW during idle periods. |
| 1.5V data retention threshold | Supports retention during brown-out events without external supervisor IC or backup capacitor sizing calculations. |
| TTL-compatible I/Os | Direct connection to legacy 3.3V microcontrollers (e.g., Renesas RX, SH, or ARM Cortex-M0+) without level translation. |

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 (4Mb), 10ns access, 3.3V only, 32-pin TSOP-II; higher speed but 10× higher standby current (3µA typ.) | Limited to high-throughput buffering where latency dominates over battery life; unsuitable for multi-year coin-cell operation. | Select when system clock exceeds 33MHz and timing margins require sub-10ns access-RMLV0408EGSP-4S2#HA1 preferred for ultra-low-power retention. |
| AS6C4008-55ZIN | 512K × 8-bit (4Mb), 55ns access, 2.7–3.6V, 32-pin SOP; same density and package but slower timing and 1µA standby (typ.) | Acceptable for cost-sensitive industrial HMI where 55ns read latency meets GUI refresh deadlines. | Choose for legacy design refresh where PCB layout reuse is mandatory and 10ns timing slack exists-RMLV0408EGSP-4S2#HA1 delivers tighter timing with lower power. |
Compared with IS61LV25616AL-10TLI and AS6C4008-55ZIN, the RMLV0408EGSP-4S2#HA1 uniquely balances 45ns performance with 0.3µA standby and 1.5V retention-enabling battery-backed SRAM functionality unattainable with either alternative without compromising speed, power, or voltage robustness.

FAQ
What is the minimum supply voltage required for data retention in RMLV0408EGSP-4S2#HA1?
The RMLV0408EGSP-4S2#HA1 guarantees data retention down to 1.5V on VCC when CS# is held high (≥ VCC − 0.2V). This specification is validated per the Low VCC Data Retention Characteristics table on page 10 of Rev. 3.00 datasheet, enabling operation during brown-out events without data loss. The RMLV0408EGSP-4S2#HA1 retains contents indefinitely at this voltage if ambient temperature remains within −40°C to +85°C.
Does RMLV0408EGSP-4S2#HA1 support true static operation without refresh cycles?
Yes, the RMLV0408EGSP-4S2#HA1 is a true asynchronous static RAM with no internal refresh circuitry required. Its Advanced LPSRAM cell structure maintains data as long as VCC is applied and CS# is high, eliminating timing-critical refresh overhead. This makes the RMLV0408EGSP-4S2#HA1 ideal for deterministic real-time systems where CPU interrupt latency must remain bounded.
What package type is used for RMLV0408EGSP-4S2#HA1, and is it RoHS compliant?
The RMLV0408EGSP-4S2#HA1 uses a 525-mil 32-pin plastic SOP (Small Outline Package) with gull-wing leads, per JEDEC MS-012AC. Renesas confirms RoHS compliance for this part number in the "Environmental Information" section of the official RMLV0408E Series datasheet (Rev. 3.00, page 1), listing lead-free (Pb-free) finish and halogen-free molding compound.
Can RMLV0408EGSP-4S2#HA1 be interfaced directly with a 3.3V microcontroller without level shifters?
Yes, the RMLV0408EGSP-4S2#HA1 features fully TTL-compatible inputs and outputs: VIH is specified at 2.2V min and VOL at 0.4V max (IOL = 2.1mA), matching standard 3.3V CMOS logic thresholds. This allows direct connection to Renesas RX65N, STMicro STM32L4, or NXP Kinetis K series MCUs without external level translation-verified in the DC Operating Conditions table (page 4).
What is the maximum operating current of RMLV0408EGSP-4S2#HA1 during active read/write cycles?
The RMLV0408EGSP-4S2#HA1 specifies a maximum operating current (ICC) of 10mA under typical read/write conditions (CS# = VIL, other inputs at VIH/VIL, I/O load = 0mA), per the DC Characteristics table on page 4. At 45ns cycle time and 100% duty, average current rises to 25mA (ICC2)-a value critical for thermal design in enclosed industrial enclosures.
