Product details
Overview
RMLV0408EGSA-4S2#KA1 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 portable instrumentation and industrial controllers.
For engineers reviewing the RMLV0408EGSA-4S2#KA1 datasheet, RMLV0408EGSA-4S2#KA1 pinout, RMLV0408EGSA-4S2#KA1 application, or RMLV0408EGSA-4S2#KA1 equivalent, key selection criteria include sTSOP-32 package compatibility, TTL-level I/O interface, low-voltage data retention down to 1.5V, and guaranteed -40°C to +85°C operation without derating.
Technical Context
The RMLV0408EGSA-4S2#KA1 implements a fully static memory architecture with asynchronous parallel interface, supporting common I/O bus sharing via three-state outputs controlled by CS#, OE#, and WE#. It uses Renesas's Advanced LPSRAM process to achieve sub-microamp standby current while maintaining 45ns read/write cycle times across full voltage and temperature range.
All control inputs (CS#, WE#, OE#) and data I/Os are TTL-compatible with VIH ≥ 2.2V and VIL ≤ 0.6V; address decoding covers A0–A18 (19-bit), enabling direct mapping of 512k × 8-bit memory space without external address latching or banking logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| I/O0–I/O7 | Bi-directional data | Common data bus with three-state output control; shares pins for read and write cycles |
| CS# | Chip select | Active-low enable controlling internal buffers; high-Z on deassertion isolates bus |
| WE# | Write enable | Active-low write strobe; initiates write when low with CS# and valid address |
| OE# | Output enable | Active-low output gate; enables read data only when CS# and OE# both low |
| VCC | Power supply | Single 2.7–3.6V supply pin; decoupling capacitor placement critical for 45ns timing stability |

FAQ
What is the maximum access time specification for RMLV0408EGSA-4S2#KA1?
The RMLV0408EGSA-4S2#KA1 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 guaranteed in the datasheet under worst-case conditions and applies to both address access (tAA) and chip select access (tACS), ensuring deterministic timing for synchronous bus interfacing without additional margining.
Does RMLV0408EGSA-4S2#KA1 support true data retention during power loss?
Yes, the RMLV0408EGSA-4S2#KA1 supports guaranteed data retention down to 1.5V VCC with CS# held high, enabling seamless backup to coin-cell batteries or supercapacitors. At 25°C, typical data retention current is 0.3µA, and the device maintains stored data indefinitely as long as VCC remains ≥1.5V and CS# remains asserted-verified per Renesas R10DS0206EJ0300 Rev.3.00.
Is RMLV0408EGSA-4S2#KA1 pin-compatible with standard 32-pin SRAM packages?
The RMLV0408EGSA-4S2#KA1 uses a 32-pin sTSOP package (8mm × 13.4mm) with industry-standard pinout matching JEDEC MO-153. Its pin arrangement-including A0–A18, I/O0–I/O7, CS#, WE#, OE#, VCC, and VSS-is functionally identical to other 512k × 8-bit SRAMs in sTSOP-32, enabling mechanical and electrical compatibility in existing layouts designed for similar density SRAMs.
What is the operating temperature range for RMLV0408EGSA-4S2#KA1?
The RMLV0408EGSA-4S2#KA1 is rated for industrial operation from -40°C to +85°C ambient temperature. This range is fully specified in the datasheet for all DC and AC parameters-including access time, standby current, and data retention-and does not require derating. The device is qualified per Renesas's industrial reliability standards and supports extended-life applications in uncontrolled environments.
Can RMLV0408EGSA-4S2#KA1 be used with 5V logic systems?
No, the RMLV0408EGSA-4S2#KA1 is not 5V-tolerant. Its inputs accept VIH ≥ 2.2V and VIL ≤ 0.6V, and absolute maximum input voltage is VCC + 0.3V (≤3.9V at 3.6V supply). Direct connection to 5V logic may damage the device. Interface with 5V systems requires level translation-e.g., TI SN74LVC4245 or discrete resistor dividers-for all control and data lines.
