Product details
Overview
RMLV0816BGSD-4S2 from Renesas Electronics is an 8Mb Advanced LPSRAM organized as 524,288-word × 16-bit (or 1,048,576-word × 8-bit), operating from a single 2.4V–3.6V supply, with 45ns max access time at 2.7–3.6V and 0.45µA typical standby current at 25°C - designed for low-power embedded systems requiring battery-backed memory retention.
For engineers reviewing the RMLV0816BGSD-4S2 datasheet, RMLV0816BGSD-4S2 pinout, RMLV0816BGSD-4S2 application, or RMLV0816BGSD-4S2 equivalent, key selection criteria include byte/word mode flexibility, µTSOP (II) package compatibility, TTL-level I/O interface, and verified data retention down to 1.5V.
Technical Context
This static RAM implements dual-mode addressing (A0–A18 for word mode; A–1–A18 for byte mode) with independent upper/lower byte control via UB# and LB#, enabling precise 8-bit or 16-bit data transfers without external logic. Its three-state DQ0–DQ15 bus supports direct TTL-compatible interfacing with microcontrollers and ASICs.
The device uses Renesas's Advanced LPSRAM process to achieve simultaneous low active power (25mA typ. at 45ns cycle) and ultra-low standby current (0.45µA typ.), with multiple data retention entry paths (CS1#, CS2, or LB#/UB# assertion) and guaranteed operation across –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory capacity | 8 Mbit (524,288 × 16 or 1,048,576 × 8) - supports flexible word/byte system architectures |
| Supply voltage | 2.4V to 3.6V - single-supply operation compatible with 3V logic families and battery-backed systems |
| Access time | 45 ns max (2.7–3.6V); 55 ns max (2.4–2.7V) - defines minimum read/write cycle timing for host controller design |
| Standby current | 0.45 µA typ. at 25°C - enables multi-year battery backup in always-on embedded applications |
| Data retention VCC | 1.5V min - maintains stored data during brown-out or backup power transitions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25616AL-10TLI | 10ns faster access (35ns), but 5µA typical standby current - 11× higher than RMLV0816BGSD-4S2 | Preferred where speed dominates over battery life; unsuitable for multi-year backup | Select only when system clock budget requires sub-40ns latency and power constraints are secondary |
| AS6C4008-55ZIN | Same 45ns access and 52-pin TSOP-II package, but 2.7–3.6V supply only (no 2.4V support) | Lacks low-voltage operation needed for brown-out resilience and wide-input DC-DC designs | Use if supply is tightly regulated ≥2.7V and data retention below 2.4V is not required |
Compared with IS61LV25616AL-10TLI and AS6C4008-55ZIN, the RMLV0816BGSD-4S2 uniquely balances ultra-low standby current (0.45µA), extended 2.4V–3.6V supply range, and industrial temperature rating - making it optimal for battery-critical, wide-input, and thermally demanding deployments.

FAQ
What is the minimum supply voltage required for data retention in RMLV0816BGSD-4S2?
The RMLV0816BGSD-4S2 guarantees data retention down to 1.5V VCC when placed in standby mode via CS1#, CS2, or LB#/UB# assertion. This allows continued memory integrity during brown-out conditions or coin-cell backup operation, with typical retention current of 0.45µA at 25°C and 3.0V supply.
Does RMLV0816BGSD-4S2 support both 8-bit and 16-bit data bus configurations?
Yes, the RMLV0816BGSD-4S2 supports dual organization: 524,288-word × 16-bit (using A0–A18) or 1,048,576-word × 8-bit (using A–1–A18). The BYTE# pin selects mode, and LB#/UB# enable independent byte access - eliminating need for external multiplexing logic.
What is the maximum operating current of RMLV0816BGSD-4S2 during active read/write cycles?
The RMLV0816BGSD-4S2 draws up to 25mA typical ICC1 current at 45ns cycle time (VCC = 3.0V, Ta = 25°C), and 30mA maximum. At slower 55ns cycles (2.4–2.7V), typical current is 20mA. These values include all internal buffers and array activity under full bus loading.
Can RMLV0816BGSD-4S2 be used with 5V-tolerant microcontrollers?
No - the RMLV0816BGSD-4S2 is strictly a 3V-family device with VIH = 2.2V (min) at 2.4–2.7V supply and 2.4V (min) at 2.7–3.6V. It is not 5V-tolerant; direct connection to 5V logic requires level translation to avoid damage and ensure signal integrity.
Is the 52-pin µTSOP (II) package of RMLV0816BGSD-4S2 RoHS compliant and lead-free?
Yes, the RMLV0816BGSD-4S2 is manufactured in a lead-free, RoHS-compliant 52-pin µTSOP (II) package per Renesas documentation R10DS0253EJ0201 Rev.2.01. The package uses matte tin plating and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements.
