Product details
Overview
RMLV1616AGSA-5U2#AA0 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. It delivers high soft error immunity (< 0.04 FIT/Mb) via on-chip ECC and supports battery backup operation in industrial data logging systems.
For engineers reviewing the RMLV1616AGSA-5U2#AA0 datasheet, RMLV1616AGSA-5U2#AA0 pinout, RMLV1616AGSA-5U2#AA0 application, or RMLV1616AGSA-5U2#AA0 equivalent, key selection criteria include its TSOP (I) package compatibility, byte/word mode flexibility via BYTE# control, no-refresh operation, and TTL-compatible I/O for legacy embedded controller interfacing.
Technical Context
This device implements a dual-bank asynchronous SRAM architecture with independent CS1# and CS2 chip select inputs enabling seamless memory expansion. Its on-chip ECC logic operates transparently during read/write cycles without external intervention or timing overhead.
The RMLV1616AGSA-5U2#AA0 supports three distinct data retention entry modes-via CS1#, CS2, or simultaneous LB#/UB# assertion-and maintains data integrity down to 1.5 V VCC while drawing only 4.4 µA (typ.) standby current at +85°C, making it suitable for long-duration battery-backed storage.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61WV102416BLL-10MLI | 10 ns faster access (45 ns), no on-chip ECC, higher ISB (25 µA typ. at +85°C) | Lacks soft error immunity and ultra-low standby; unsuitable for long-term battery backup | Select only if speed is primary constraint and radiation tolerance is not required |
| AS6C1008-55ZIN | Same 55 ns access, no ECC, 3.3 V only (2.7–3.6 V range not supported), ISB = 15 µA (typ.) | Cannot operate below 2.7 V; incompatible with brown-out retention scenarios | Use only in fixed 3.3 V systems where voltage margin and data integrity are non-critical |
Compared with IS61WV102416BLL-10MLI and AS6C1008-55ZIN, the RMLV1616AGSA-5U2#AA0 uniquely combines 55 ns access, sub-µA standby, on-chip ECC, and 1.5 V data retention - enabling robust, maintenance-free operation in safety-critical, battery-constrained edge devices where alternatives require trade-offs in reliability, power, or voltage range.

FAQ
What is the maximum operating temperature range for the RMLV1616AGSA-5U2#AA0?
The RMLV1616AGSA-5U2#AA0 is rated for operation from −40°C to +85°C ambient temperature. Its standby current specification of 4.4 µA (typ.) is validated at +85°C, confirming stable low-power performance across the full industrial temperature range. This makes the RMLV1616AGSA-5U2#AA0 suitable for deployment in harsh environments such as outdoor instrumentation or under-hood automotive subsystems.
Does the RMLV1616AGSA-5U2#AA0 support both 8-bit and 16-bit data bus configurations?
Yes, the RMLV1616AGSA-5U2#AA0 supports both configurations: 1,048,576-word × 16-bit (default word mode) and 2,097,152-word × 8-bit (byte mode). Mode selection is controlled by the BYTE# pin on the 48-pin TSOP (I) package - tied to VCC for word mode, to GND for byte mode. The RMLV1616AGSA-5U2#AA0 does not require external logic or configuration registers to switch modes.
How does the on-chip ECC in the RMLV1616AGSA-5U2#AA0 improve system reliability?
The RMLV1616AGSA-5U2#AA0 integrates hardware ECC that automatically corrects single-bit errors and detects double-bit errors on every read access, with zero software overhead or timing penalty. Its soft error immunity is quantified at <0.04 FIT/Mb - over 10× better than standard SRAMs - directly enhancing uptime and data fidelity in radiation-exposed applications like aerospace or nuclear instrumentation where the RMLV1616AGSA-5U2#AA0 is deployed.
Can the RMLV1616AGSA-5U2#AA0 retain data during main power loss?
Yes, the RMLV1616AGSA-5U2#AA0 supports data retention down to 1.5 V VCC using three independent entry methods: asserting CS1#, CS2, or both LB# and UB# simultaneously. In retention mode, typical current draw is 4.4 µA at +85°C, enabling multi-year data hold on a single coin cell. This capability is explicitly validated in the RMLV1616AGSA-5U2#AA0 datasheet's Low VCC Data Retention Characteristics table.
Is the RMLV1616AGSA-5U2#AA0 pin-compatible with other devices in the RMLV1616A-U Series?
Yes, the RMLV1616AGSA-5U2#AA0 shares identical pinout and footprint with all 48-pin TSOP (I) variants in the RMLV1616A-U Series, including RMLV1616AGSA-4U2 (45 ns). Differences are limited to access time grading and temperature screening - no PCB redesign is needed when migrating between -4U2 and -5U2 versions. Both use the same JEITA package code P-TSOP(1)48−12×18.4−0.50.
