Product details
Overview
RMLV1616AGSD-5S2 from Renesas Electronics is a 16Mb Advanced LPSRAM organized as 1,048,576-word × 16-bit (or 2,097,152-word × 8-bit), operating from a single 2.7–3.6V supply with 55ns max access time and 0.5µA typical standby current. It serves as a low-power, battery-backed memory buffer in portable instrumentation, industrial data loggers, and embedded controllers requiring non-volatile data retention during power loss.
For engineers reviewing the RMLV1616AGSD-5S2 datasheet, RMLV1616AGSD-5S2 pinout, RMLV1616AGSD-5S2 application, or RMLV1616AGSD-5S2 equivalent, key selection criteria include µTSOP (II) package compatibility, byte/word mode flexibility via BYTE# control, low-voltage data retention down to 1.5V, and dual chip-select architecture for multi-bank memory systems.
Technical Context
The RMLV1616AGSD-5S2 implements a dual-select static RAM architecture with independent CS1# and CS2 inputs enabling hierarchical bank enable control. Its BYTE# pin configures word (16-bit) or byte (8-bit) addressing modes-supported only in TSOP (I) and µTSOP (II) packages-and directly interfaces with 8-bit or 16-bit microcontroller data buses without external logic.
It features three-state bidirectional DQ0–DQ15 I/Os with TTL-compatible input thresholds (VIH ≥ 2.2V, VIL ≤ 0.6V), LB#/UB# controlled byte write capability, and four distinct data retention entry paths (via CS1#, CS2, or LB#/UB# assertion) ensuring robust operation under brown-out conditions at VCC as low as 1.5V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25616AL-10TLI | 10ns faster access (45ns), 48-pin TSOP (I), no BYTE# pin, higher standby current (1µA typ.) | Lacks byte/word mode flexibility; requires fixed 16-bit bus; less suitable for battery-constrained designs | Choose when speed > power efficiency and board layout accommodates larger TSOP (I) |
| AS6C4008-55TIN | Same 55ns speed, 48-ball FBGA, no BYTE# or CS2 pin, 1.5µA standby current | Smaller footprint but no byte-mode support; incompatible pinout and control logic for RMLV1616AGSD-5S2 migration | Prefer for space-constrained designs where byte-mode operation is unnecessary |
Compared with IS61LV25616AL-10TLI and AS6C4008-55TIN, the RMLV1616AGSD-5S2 uniquely combines µTSOP (II) compactness, hardware-selectable byte/word mode, and sub-1µA standby - making it optimal for portable, battery-backed, and mixed-bus embedded systems where layout density and power budget are co-constrained.

FAQ
What is the minimum VCC required for data retention in RMLV1616AGSD-5S2?
The RMLV1616AGSD-5S2 maintains data integrity down to 1.5V VCC under specified conditions (CS2 ≤ 0.2V or CS1# ≥ VCC−0.2V). This low-voltage retention capability enables use with supercapacitors or depleted batteries without external backup circuitry. The RMLV1616AGSD-5S2 achieves this while drawing only 0.5µA typical current at +25°C, making it ideal for energy-harvesting and long-life portable systems.
Does RMLV1616AGSD-5S2 support both 8-bit and 16-bit bus interfaces?
Yes, the RMLV1616AGSD-5S2 supports both configurations via the BYTE# pin: when asserted low, it operates in 8-bit mode (2M-word × 8-bit) using A-1 through A19 and DQ0–DQ7; when high, it operates in 16-bit mode (1M-word × 16-bit) using A0–A19 and DQ0–DQ15. This eliminates external bus-width translation logic. The RMLV1616AGSD-5S2's µTSOP (II) package and TTL-compatible I/O ensure drop-in compatibility with common 8-bit and 16-bit microcontrollers.
What is the function of the CS2 pin on RMLV1616AGSD-5S2?
The CS2 pin on RMLV1616AGSD-5S2 is an active-high secondary chip select that works in conjunction with active-low CS1# to enable hierarchical memory banking. When CS2 is high and CS1# is low, the device is selected; if CS2 is low, the device enters standby regardless of CS1#. This dual-select architecture simplifies address decoding in systems with multiple SRAMs and enables low-power deselection without toggling CS1#. The RMLV1616AGSD-5S2 uses CS2 also as a primary control path for data retention entry.
Can RMLV1616AGSD-5S2 be used with a 2.5V supply?
No, the RMLV1616AGSD-5S2 requires a minimum supply voltage of 2.7V per its DC Operating Conditions specification. Operation below 2.7V violates absolute maximum ratings and may result in undefined behavior, data corruption, or failure to retain memory contents. While the device supports data retention down to 1.5V, that mode requires specific control pin states (e.g., CS2 ≤ 0.2V) and is not intended for active read/write operation. The RMLV1616AGSD-5S2 is strictly a 2.7–3.6V device for functional operation.
Is the BYTE# pin present on all RMLV1616A Series packages?
No, the BYTE# pin is supported only on the 48-pin TSOP (I) and 52-pin µTSOP (II) variants-including the RMLV1616AGSD-5S2-but is absent on the 48-ball FBGA version. In FBGA packages, the device defaults to BYTE#=H (word mode) internally. Therefore, designers selecting the RMLV1616AGSD-5S2 gain hardware-configurable bus-width flexibility, whereas FBGA users must implement byte access in software or external logic. This distinction is explicitly documented in Renesas' R10DS0258EJ0101 datasheet Notes 1 and 3.
