Product details
Overview
RMLV1616AGSA-4U2#KA0 from Renesas Electronics is a 16-Mbit asynchronous low-power SRAM organized as 1,048,576-word × 16-bit (or configurable as 2,097,152-word × 8-bit), featuring 45 ns max access time, ultra-low standby current (0.4 µA typ. at 25°C), and on-chip soft error immunity (< 0.04 FIT/Mb). It operates from a single 2.7–3.6 V supply and supports battery backup systems in industrial and embedded applications.
For engineers reviewing the RMLV1616AGSA-4U2#KA0 datasheet, RMLV1616AGSA-4U2#KA0 pinout, RMLV1616AGSA-4U2#KA0 application, or RMLV1616AGSA-4U2#KA0 equivalent, this device delivers verified low-voltage data retention (down to 1.5 V), TTL-compatible I/O, no-refresh operation, and dual chip select for memory expansion - critical for power-constrained, high-reliability designs.
Technical Context
This SRAM implements a fully static architecture with no clocks or refresh cycles, using address latching and three-state bidirectional I/O buffers. Its dual chip select (CS1#, CS2) enables seamless memory banking and hierarchical decoding without external logic.
It supports two operational modes via the BYTE# pin: word mode (1M × 16) and byte mode (2M × 8), with mode selection fixed by tying BYTE# to VCC (word) or VSS (byte); the FBGA variant defaults to word mode only. Data retention is maintained under low VCC (1.5–3.6 V) when entering standby via CS2 low, CS1# high, or LB#/UB# high conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar asynchronous low-power SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV102416AL-10TLI | 10 ns slower access (55 ns), no on-chip soft error mitigation, higher ISB (2 µA typ.) | Lacks FIT-rated reliability; suitable only where radiation tolerance is not required | Select when cost sensitivity outweighs FIT requirement and 55 ns timing is acceptable |

FAQ
What is the maximum access time specification for RMLV1616AGSA-4U2#KA0?
The RMLV1616AGSA-4U2#KA0 has a maximum access time of 45 ns, measured as address access time (tAA) and read cycle time (tRC) under standard test conditions (VCC = 2.7–3.6 V, Ta = −40°C to +85°C). This value is guaranteed across the full industrial temperature range and applies to both word-mode (1M × 16) and byte-mode (2M × 8) configurations when used with the 48-pin TSOP (I) package.
Does RMLV1616AGSA-4U2#KA0 require an external clock or refresh circuitry?
No, the RMLV1616AGSA-4U2#KA0 is a fully asynchronous SRAM and requires no external clock or refresh circuitry. Its static design uses only control signals (CS1#, CS2, WE#, OE#, UB#, LB#) and address/data lines. This eliminates timing synchronization overhead and simplifies integration into microcontroller- or FPGA-based systems where deterministic, jitter-free memory access is essential.
How does the BYTE# pin function on RMLV1616AGSA-4U2#KA0?
The BYTE# pin on RMLV1616AGSA-4U2#KA0 configures memory organization: tying BYTE# to VCC selects 1M-word × 16-bit (word mode), while tying it to VSS selects 2M-word × 8-bit (byte mode). This pin is present only on the 48-pin TSOP (I) package (RMLV1616AGSA-4U2#KA0); the FBGA variants operate exclusively in word mode. Mode switching must occur during power-up or controlled reset - not dynamically during active operation.
What is the minimum supply voltage for data retention in RMLV1616AGSA-4U2#KA0?
The RMLV1616AGSA-4U2#KA0 guarantees data retention down to 1.5 V VCC when placed in standby via CS2 low, CS1# high, or LB#/UB# high assertion. This low-threshold retention enables reliable operation during brownout events and seamless handover to backup batteries - a key differentiator versus standard SRAMs that typically require ≥ 2.0 V for retention.
Is RMLV1616AGSA-4U2#KA0 compatible with TTL-level logic interfaces?
Yes, the RMLV1616AGSA-4U2#KA0 features fully TTL-compatible inputs and outputs: VIH = 2.2 V min, VIL = 0.6 V max, VOH = 2.4 V min (IOH = −1 mA), and VOL = 0.4 V max (IOL = 2 mA). This allows direct connection to legacy microcontrollers, CPLDs, and FPGAs without level-shifting components - reducing BOM count and PCB area in cost-sensitive industrial designs.
