Product details
Overview
RMLV1616AGSA-5U2#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), operating from a single 2.7–3.6 V supply, with 55 ns max access time and ultra-low standby current of 4.4 µA (typ.) at +85°C - deployed in battery-backed industrial control and medical data logging systems.
For engineers reviewing the RMLV1616AGSA-5U2#KA0 datasheet, RMLV1616AGSA-5U2#KA0 pinout, RMLV1616AGSA-5U2#KA0 application, or RMLV1616AGSA-5U2#KA0 equivalent, this page delivers verified timing specs, byte/word mode configuration logic, on-chip soft-error immunity (<0.04 FIT/Mb), TSOP(I) package mapping, and battery-retention behavior under low-VCC.
Technical Context
This SRAM implements dual chip-select architecture (CS1# and CS2) enabling seamless memory expansion without external decoding logic; it supports three independent enable paths - OE# for output gating, LB#/UB# for byte-level write control, and BYTE# (TSOP-only) to dynamically switch between 1M×16 and 2M×8 organization.
No clocks or refresh circuitry are required; operation relies entirely on asynchronous address and control strobes. Data retention is maintained down to 1.5 V via three distinct entry modes: CS2 low, CS1# high (with CS2 ≥ VCC−0.2 V), or simultaneous LB#/UB# high - each validated across −40°C to +85°C with sub-µA retention current.

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 |
|---|---|---|---|
| IS61WV102416BLL-10MLI | 10 ns faster access (45 ns), higher ICC1 (35 mA typ.), no on-chip ECC, same 48-pin TSOP(I) footprint | Lacks soft-error immunity; requires external error detection in safety-critical use cases | Select only when speed outweighs radiation tolerance and battery life constraints |
| AS6C1008-55ZIN | Same 55 ns access, but 128K × 8 organization (1 Mbit), 1.8–3.6 V supply, no BYTE# mode switching | Half capacity and fixed 8-bit bus - unsuitable for 16-bit microcontroller interfaces or byte/word reconfiguration | Consider only for cost-sensitive, non-backup, low-density designs with strict voltage flexibility needs |
Compared with IS61WV102416BLL-10MLI and AS6C1008-55ZIN, the RMLV1616AGSA-5U2#KA0 uniquely combines 16-Mbit density, on-chip ECC, battery-retention capability, and dynamic byte/word mode selection - making it the sole option meeting simultaneous requirements for industrial longevity, functional safety, and flexible bus interface in constrained form factors.

FAQ
What is the maximum operating temperature range for the RMLV1616AGSA-5U2#KA0?
The RMLV1616AGSA-5U2#KA0 is rated for continuous operation from −40°C to +85°C. This industrial temperature grade is validated across all DC and AC specifications including standby current, access time, and data retention behavior - ensuring reliability in harsh environments such as factory automation controllers and outdoor utility meters where thermal cycling occurs regularly. The RMLV1616AGSA-5U2#KA0 maintains its 55 ns max access time and sub-µA retention current throughout this full range.
Does the RMLV1616AGSA-5U2#KA0 support both 16-bit and 8-bit data bus configurations?
Yes, the RMLV1616AGSA-5U2#KA0 supports both configurations via the BYTE# pin, which is present only on the 48-pin TSOP(I) package. When BYTE# is tied to VCC, the device operates in 1M-word × 16-bit mode; when tied to VSS, it configures as 2M-word × 8-bit. This hardware-selectable mode eliminates firmware overhead and enables runtime adaptation in field-upgradable systems. The RMLV1616AGSA-5U2#KA0 does not require reinitialization to switch modes - the change takes effect on the next valid access cycle.
How does the on-chip ECC in the RMLV1616AGSA-5U2#KA0 improve system reliability?
The RMLV1616AGSA-5U2#KA0 integrates on-chip ECC that achieves a soft error rate below 0.04 FIT/Mb - over 10× better than standard SRAMs without ECC. This is realized through Renesas's Advanced LPSRAM process and dedicated error-detection circuitry, correcting single-bit upsets and detecting double-bit errors transparently. Unlike software-based ECC, this hardware implementation adds zero latency and zero CPU overhead, making the RMLV1616AGSA-5U2#KA0 ideal for real-time systems like train control units where deterministic response is mandated by safety standards.
What are the valid data retention voltage and current specifications for the RMLV1616AGSA-5U2#KA0?
The RMLV1616AGSA-5U2#KA0 retains stored data down to VCC = 1.5 V, with typical retention current of 4.4 µA at +85°C. Retention is enabled via three hardware-controlled entry conditions: CS2 ≤ 0.2 V, CS1# ≥ VCC−0.2 V (with CS2 in valid state), or simultaneous LB# and UB# ≥ VCC−0.2 V. These modes are electrically validated and do not require clocking or initialization sequences. The RMLV1616AGSA-5U2#KA0 exits retention in ≤5 ms after VCC rises above 2.7 V and control signals stabilize.
Is the RMLV1616AGSA-5U2#KA0 pin-compatible with other devices in the RMLV1616A-U Series?
Yes, the RMLV1616AGSA-5U2#KA0 shares identical pinout and electrical characteristics with other 48-pin TSOP(I) variants in the RMLV1616A-U Series, including RMLV1616AGSA-4U2 (45 ns). All share the same address/data/control mapping, power sequencing, and timing reference levels. However, the RMLV1616AGSA-5U2#KA0 is not pin-compatible with FBGA variants (e.g., RMLV1616AGBG-5U2) due to differing ball layout and absence of BYTE# functionality in FBGA packages. The RMLV1616AGSA-5U2#KA0 requires no PCB redesign when substituting within the TSOP(I) family.
