Product details
Overview
RMLV1616AGSA-5S2#KA0 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 supports byte/word mode operation via LB#/UB#/BYTE# control and is designed for low-power battery-backed memory applications in industrial and embedded systems.
For engineers reviewing the RMLV1616AGSA-5S2#KA0 datasheet, RMLV1616AGSA-5S2#KA0 pinout, RMLV1616AGSA-5S2#KA0 application, or RMLV1616AGSA-5S2#KA0 equivalent, key selection criteria include TSOP (I) package compatibility, TTL-level I/O interface, 48-pin pinout validation, and low-voltage data retention down to 1.5V - critical for power-fail-safe designs.
Technical Context
This static RAM implements dual chip select (CS1#, CS2), independent upper/lower byte enable (UB#, LB#), and BYTE#-controlled word/byte addressing mode. Its architecture supports three-state bidirectional DQ0–DQ15 I/O with direct TTL compatibility on all pins and simultaneous high-impedance control via OE#, WE#, and chip select logic.
The device features four distinct data retention entry modes - triggered by CS1#, CS2, or LB#/UB# assertion - enabling flexible low-power hold states at VCC ≥ 1.5V. Standby current scales with temperature (0.5µA @ 25°C, up to 5µA @ 85°C), and AC timing guarantees tAA ≤ 55ns, tOE ≤ 22ns, and tWHZ ≤ 18ns across -40°C to +85°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV1616AL-10TLI | 10ns faster access (45ns), 54-pin TSOP-II, no BYTE# pin, higher 2mA standby current | Lacks byte/word mode switching; requires fixed 16-bit bus design | Preferred when speed >55ns is mandatory and board layout accommodates larger 54-pin footprint |
| AS6C1616-55TIN | Same 55ns speed, 48-pin TSOP-I, but 2.5–3.6V supply range and 1µA standby (typ.) | Wider VCC tolerance but weaker low-VCC retention (no spec below 2.5V) | Valid drop-in for 3.3V-only systems where battery backup is not required |
Compared with RMLV1616AGSA-5S2#KA0, IS61LV1616AL-10TLI trades byte-mode flexibility for raw speed and AS6C1616-55TIN sacrifices low-voltage retention for broader supply tolerance - making RMLV1616AGSA-5S2#KA0 uniquely suited for battery-critical, mixed-width embedded memory.

FAQ
What is the minimum supply voltage required to retain data in RMLV1616AGSA-5S2#KA0?
RMLV1616AGSA-5S2#KA0 guarantees data retention down to 1.5V VCC when entering retention mode via CS1#, CS2, or LB#/UB# assertion. At this voltage, typical retention current is 0.5µA at 25°C, scaling to 5µA at 85°C. This enables use with small backup capacitors or coin cells in space-constrained designs.
Does RMLV1616AGSA-5S2#KA0 support both 8-bit and 16-bit data bus configurations?
Yes, RMLV1616AGSA-5S2#KA0 supports configurable 8-bit or 16-bit operation via the BYTE# pin. When BYTE# = VIH, it operates in 16-bit word mode (A0–A19, DQ0–DQ15); when BYTE# = VIL, it switches to 8-bit byte mode (A-1–A19, DQ0–DQ7). This feature is implemented in the 48-pin TSOP (I) package of RMLV1616AGSA-5S2#KA0.
What is the maximum clock frequency supported by RMLV1616AGSA-5S2#KA0 in asynchronous operation?
RMLV1616AGSA-5S2#KA0 is an asynchronous SRAM and does not use a clock signal. Its performance is defined by access time (tAA ≤ 55ns) and cycle time (tRC ≤ 55ns), enabling reliable interfacing with microcontrollers or FPGAs running up to ~16MHz bus clocks when timing margins are observed.
How does the LB# and UB# pin functionality differ from standard byte-enable signals in RMLV1616AGSA-5S2#KA0?
In RMLV1616AGSA-5S2#KA0, LB# and UB# are active-low, independent byte-select controls that gate write operations to DQ0–DQ7 or DQ8–DQ15 respectively. Unlike generic byte enables, they also participate in retention mode activation and interact with BYTE# to define addressing boundaries - enabling true 8-bit writes without affecting adjacent bytes in 16-bit memory maps.
Is RMLV1616AGSA-5S2#KA0 pin-compatible with other devices in the RMLV1616A family?
RMLV1616AGSA-5S2#KA0 uses the 48-pin TSOP (I) package and shares identical pinout with RMLV1616AGSA-5S2 (non-#KA0 variant). However, it is not pin-compatible with the 52-pin µTSOP (II) or 48-ball FBGA variants due to differing pin counts and layouts - each package type has unique pin assignments per Renesas datasheet Figure 1.
