Product details
Overview
RMLV0408EGSA-4S2#AA1 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 retention in portable instrumentation and industrial control systems.
For engineers reviewing the RMLV0408EGSA-4S2#AA1 datasheet, RMLV0408EGSA-4S2#AA1 pinout, RMLV0408EGSA-4S2#AA1 application, or RMLV0408EGSA-4S2#AA1 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
The RMLV0408EGSA-4S2#AA1 implements a fully static memory architecture with asynchronous parallel interface, using address latching via A0–A18 (19-bit) and bidirectional I/O0–I/O7 (8-bit) with three-state output control. Chip select (CS#), write enable (WE#), and output enable (OE#) signals govern read/write cycles and high-impedance states.
It features equal access and cycle times (tRC = tAA = 45ns max), supports direct TTL compatibility on all inputs/outputs, and enters ultra-low-power data retention mode when CS# is high and VCC ≥ 1.5V - enabling reliable backup without external power switching circuitry.

|---|---|---|---|
| IS61LV25616AL-10TLI | 256K × 16-bit organization, 10ns access, 3.3V only, 44-pin TSOP | Higher density per pin but wider data bus; requires PCB redesign for 16-bit interface | Select if system uses 16-bit data path and requires faster access; not drop-in compatible with RMLV0408EGSA-4S2#AA1 |
| AS6C4008-55ZIN | 4Mb × 8-bit, 55ns access, 2.7–3.6V, 32-pin SOP; higher standby current (1µA typ.) | Same memory map and voltage range but slower timing and larger SOP footprint | Choose when sTSOP assembly is unavailable and board layout allows 525-mil SOP; verify timing margin for 45ns-critical designs |
Compared with IS61LV25616AL-10TLI and AS6C4008-55ZIN, the RMLV0408EGSA-4S2#AA1 delivers optimal balance of 45ns speed, 0.3µA standby, and compact sTSOP-32 packaging - making it preferred for space- and power-constrained industrial and medical edge devices requiring byte-wide access.

FAQ
What is the minimum VCC required to retain data in RMLV0408EGSA-4S2#AA1?
The RMLV0408EGSA-4S2#AA1 guarantees data retention down to 1.5V VCC, provided CS# remains high (≥ VCC − 0.2V) and all other inputs are within valid voltage ranges. This enables fail-safe logging during brownout conditions without external power-fail detection circuitry - a core design advantage of the RMLV0408EGSA-4S2#AA1.
Is RMLV0408EGSA-4S2#AA1 pin-compatible with other 32-pin SRAMs like the AS6C4008 series?
No, RMLV0408EGSA-4S2#AA1 is not pin-compatible with AS6C4008-series devices. While both use 32-pin packages, the pin assignments differ: RMLV0408EGSA-4S2#AA1 places A11–A18 on the top row and I/O0–I/O7 on the bottom row in sTSOP, whereas AS6C4008 uses alternate pin mapping. Always verify physical layout against the RMLV0408EGSA-4S2#AA1 datasheet before substitution.
Does RMLV0408EGSA-4S2#AA1 support true static operation without refresh cycles?
Yes, the RMLV0408EGSA-4S2#AA1 is a fully static RAM - it requires no refresh cycles, clock, or periodic access to retain data. Its CMOS-based cell design holds state indefinitely as long as VCC and bias conditions remain within specification, making the RMLV0408EGSA-4S2#AA1 ideal for low-power, interrupt-driven embedded systems.
What is the maximum operating frequency supported by RMLV0408EGSA-4S2#AA1?
The RMLV0408EGSA-4S2#AA1 does not operate on a clock signal; it is an asynchronous SRAM. Its timing is governed by access and cycle time limits: maximum effective throughput is determined by tRC = 45ns, supporting up to ~22.2 MHz random-access bandwidth. System timing must comply with all AC specifications including tAS, tDH, and tWP - not just tRC - to ensure reliable operation of the RMLV0408EGSA-4S2#AA1.
Can RMLV0408EGSA-4S2#AA1 be used with 5V-tolerant microcontrollers?
No, RMLV0408EGSA-4S2#AA1 is strictly a 3.3V-family device with absolute maximum VCC of +4.6V and VIH limited to VCC + 0.3V. Direct connection to 5V I/O microcontrollers will exceed input voltage ratings and risk damage. Level translation (e.g., TXB0108 or discrete resistor dividers) is mandatory when interfacing the RMLV0408EGSA-4S2#AA1 with 5V logic systems.
