Product details
Overview
RMLV0408EGSP-4S2#HA0 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 applications in portable instrumentation and industrial control systems.
For engineers reviewing the RMLV0408EGSP-4S2#HA0 datasheet, RMLV0408EGSP-4S2#HA0 pinout, RMLV0408EGSP-4S2#HA0 application, or RMLV0408EGSP-4S2#HA0 equivalent, key selection criteria include its sTSOP-compatible 32-pin SOP package, TTL-compatible I/O, common data bus architecture, and low-voltage data retention down to 1.5V.
Technical Context
The RMLV0408EGSP-4S2#HA0 implements a synchronous static RAM architecture with fully decoded address inputs (A0–A18), three-state bidirectional I/O lines (I/O0–I/O7), and standard control signals (CS#, WE#, OE#). Its block diagram confirms independent row/column decoders feeding a 2,048 × 2,048 memory matrix.
It supports equal read/write cycle times (tRC = tWC = 45ns max), features direct TTL compatibility on all pins, and enters ultra-low-power data retention mode when CS# is high and VCC ≥ 1.5V - enabling operation in battery backup systems without external power switching circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4Mb (524,288 × 8-bit) - supports 512KB of byte-addressable storage for firmware buffers or real-time data logging. |
| Access time | 45ns max - enables interface with microcontrollers running at ≤22 MHz without wait states. |
| Supply voltage | 2.7V to 3.6V - compatible with 3.3V logic domains and tolerant of Li-ion battery discharge profiles. |
| Standby current | 0.3µA typ. at +25°C - extends battery life to years in always-on backup mode. |
| Data retention VCC | 1.5V min - maintains SRAM contents during brown-out or primary power loss without auxiliary supply. |
| I/O interface | Common bidirectional bus with three-state output - reduces PCB trace count and simplifies bus arbitration. |
| Operating temperature | -40°C to +85°C - qualified for industrial ambient environments including factory automation and outdoor telemetry. |
Pinout & Package
The RMLV0408EGSP-4S2#HA0 is supplied in a 525-mil 32-pin plastic SOP package (standard JEDEC MS-012AC), with 0.050" lead pitch and gull-wing leads suitable for through-hole or surface-mount assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply | Primary 2.7–3.6V supply input; decoupling capacitor required within 10mm for stable operation. |
| VSS | Ground | System reference ground; must be connected to low-impedance analog/digital return plane. |
| A0–A18 | Address input | 19-bit address bus supporting full 524,288-word decoding; no external address latching needed. |
| I/O0–I/O7 | Data input/output | Bidirectional 8-bit data bus with three-state control; shares pins for read and write cycles. |
| CS# | Chip select | Active-low enable controlling internal buffers; high state forces I/O into high-Z and enables data retention mode. |
| WE# | Write enable | Active-low signal initiating write cycle when CS# is also low; defines write timing window with tWP ≥ 35ns. |
| OE# | Output enable | Active-low control for output drivers only; does not affect write operations or internal state. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply 3V operation | Eliminates need for dual-rail supplies or level shifters in 3.3V embedded systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25616AL-10TLI | 256K × 16-bit organization, 10ns access, 3.3V-only (3.135–3.465V), 12µA standby current | Higher speed but larger footprint and higher power; lacks sub-2V data retention | Select for high-throughput buffering where 45ns latency is unacceptable and board space permits 44-pin TSOP. |
| AS6C4008-55ZIN | 4Mb × 8-bit, 55ns access, 2.7–3.6V, 1µA standby, 2.0V min retention voltage | Slower access, slightly higher standby draw, weaker retention margin than RMLV0408EGSP-4S2#HA0 | Select when cost sensitivity outweighs marginal performance loss and extended battery life is secondary. |
Compared with IS61LV25616AL-10TLI and AS6C4008-55ZIN, the RMLV0408EGSP-4S2#HA0 delivers superior energy efficiency in battery backup roles due to its 0.3µA standby and 1.5V data retention - critical for multi-year deployments where replacement access is impractical.

FAQ
What is the maximum access time specification for RMLV0408EGSP-4S2#HA0?
The RMLV0408EGSP-4S2#HA0 has a maximum access time of 45ns across its full operating temperature range (-40°C to +85°C) and supply voltage range (2.7V to 3.6V). This value is measured from address valid to data valid under standard test conditions (VIL = 0.4V, VIH = 2.4V, load = 30pF), and applies to both read and write cycles as part of its equal-cycle-time design.
Does RMLV0408EGSP-4S2#HA0 support true data retention during power loss?
Yes, the RMLV0408EGSP-4S2#HA0 supports guaranteed data retention down to 1.5V VCC when CS# is held high, with typical retention current of 0.3µA at +25°C. This feature enables reliable operation in battery backup configurations where primary power may fail unexpectedly, and is validated per the Low VCC Data Retention Characteristics table in the official Renesas datasheet R10DS0206EJ0300.
What package type is used for RMLV0408EGSP-4S2#HA0?
The RMLV0408EGSP-4S2#HA0 uses a 525-mil 32-pin plastic SOP (Small Outline Package) conforming to JEDEC MS-012AC, with gull-wing leads and 0.050" pitch. It is distinct from the sTSOP and TSOP (II) variants in the RMLV0408E family and is shipped in embossed tape format per the orderable part number suffix #HA0.
Is RMLV0408EGSP-4S2#HA0 compatible with standard TTL logic levels?
Yes, the RMLV0408EGSP-4S2#HA0 is directly TTL-compatible: VIH is specified at 2.2V minimum (up to VCC+0.3V), VIL at 0.6V maximum, and VOH/VOL meet TTL thresholds under rated loads (VOH ≥ 2.4V at -1mA, VOL ≤ 0.4V at 2.1mA). All inputs and outputs comply, eliminating need for level-shifting circuitry in legacy 5V-tolerant or mixed-voltage systems.
How many address and data lines does RMLV0408EGSP-4S2#HA0 require?
The RMLV0408EGSP-4S2#HA0 requires 19 address lines (A0–A18) to decode its 524,288-word memory array and 8 bidirectional data lines (I/O0–I/O7). Control signals include three active-low lines: CS#, WE#, and OE#. No additional address latches or data direction controllers are needed due to its common I/O bus architecture and integrated three-state output drivers.
