Product details
Overview
RMLV0416EGBG-4S2#KC0 from Renesas Electronics is a 4Mb Advanced LPSRAM organized as 262,144-word × 16-bit, operating on a single 3V supply (2.7–3.6V), with 45ns max access time, 0.3µA typical standby current, and FBGA-48 packaging - designed for low-power battery-backed memory applications in industrial controllers and portable instrumentation.
For engineers reviewing the RMLV0416EGBG-4S2#KC0 datasheet, RMLV0416EGBG-4S2#KC0 pinout, RMLV0416EGBG-4S2#KC0 application, or RMLV0416EGBG-4S2#KC0 equivalent, key selection criteria include byte-selectable 16-bit I/O architecture, TTL-compatible interface levels, data retention down to 1.5V VCC, and dual chip select logic enabling multi-bank memory expansion without external gating.
Technical Context
This SRAM implements a synchronous, common I/O bus architecture with independent upper and lower byte enables (UB#/LB#) and dual chip select inputs (CS1#, CS2) that support hierarchical memory mapping. Its control logic decodes address transitions, write pulses, and output enable timing to deliver deterministic read/write cycles at 45ns.
The device supports three distinct data retention modes activated by CS2 ≤ 0.2V, CS1# ≥ VCC−0.2V (with CS2 high), or simultaneous LB#/UB# ≥ VCC−0.2V - each enabling sub-1µA retention current while maintaining full data integrity across −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4 Mbit (262,144 × 16-bit); provides compact, byte-accessible storage for firmware buffers and real-time data logging. |
| Supply voltage | 2.7–3.6 V; compatible with standard 3.3V systems and tolerant of brown-out conditions during backup operation. |
| Access time | 45 ns max; ensures deterministic timing for microcontroller interfaces running up to ~22 MHz burst access. |
| Standby current | 0.3 µA typ. at +25°C; enables multi-year battery life in always-on backup mode without external power switches. |
| Data retention VCC | 1.5 V min; guarantees nonvolatile data hold during deep sleep or main supply failure without auxiliary circuitry. |
| I/O interface | Common bidirectional 16-bit bus with three-state outputs; eliminates need for external transceivers in space-constrained designs. |
| Operating temperature | −40°C to +85°C; qualified for industrial-grade deployment in programmable logic controllers and medical telemetry devices. |
Pinout & Package
Package: 48-ball fine-pitch BGA (0.75 mm pitch), 7.0 mm × 8.0 mm footprint, JEDEC MO-276 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply | Primary 3V core supply; two dedicated pins ensure low-impedance routing and reduced switching noise. |
| VSS | Ground | System ground reference; four pins provide robust return path for I/O and internal logic currents. |
| A0–A17 | Address input | 18-bit address bus supporting full 262k-word addressing; no address multiplexing required. |
| I/O0–I/O15 | Data input/output | 16-bit bidirectional data bus with TTL-compatible thresholds; shared pins reduce pin count and PCB layer count. |
| CS1#, CS2 | Chip select | Dual active-low selects enable bank decoding and partial memory disable without external logic. |
| OE#, WE#, LB#, UB# | Control inputs | Independent output enable, write enable, and byte-select controls allow granular 8-bit or 16-bit access per cycle. |
| NC | No connection | Three unassigned balls (A1, D1, G1); must be left floating or grounded per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage data retention | Operates down to 1.5V VCC with <2µA retention current - eliminates need for external backup batteries or supercaps in many applications. |
| Byte-selectable I/O | Independent LB# and UB# controls enable true 8-bit writes/reads without masking or software overhead - critical for mixed-data-width peripherals. |
| TTL-compatible signaling | All inputs accept 0.6V/2.4V thresholds and outputs drive ±1mA loads - interoperates directly with legacy 3.3V microcontrollers and FPGAs. |
| Dual chip select architecture | CS1# and CS2 allow hierarchical memory banking (e.g., CS2 = global enable, CS1# = sub-bank select) - simplifies address decoding in multi-SRAM systems. |
| Zero-power standby | 0.3µA typical ISB1 at +25°C - reduces quiescent power in always-on edge nodes and sensor concentrators. |

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 (35ns), but 5µA typical standby current; TSOP-44 only, no FBGA option. | Preferred for speed-critical embedded controllers where board space allows larger TSOP package. | Select when system clock exceeds 28 MHz and thermal budget permits higher idle power. |
| AS6C4008-55TIN | Slower 55ns access, 1µA standby, same 48-ball FBGA-0.8mm pitch - not pin-compatible with RMLV0416EGBG-4S2#KC0. | Suitable for cost-sensitive industrial HMI where timing margin is relaxed and footprint compatibility is secondary. | Choose only after verifying PCB pad layout adaptation and validating timing slack in worst-case temperature/voltage corners. |
Compared with IS61LV25616AL-10TLI and AS6C4008-55TIN, RMLV0416EGBG-4S2#KC0 uniquely balances ultra-low standby power (0.3µA), industrial temperature range, and FBGA-48 packaging - making it optimal for battery-constrained, space-limited, and thermally demanding deployments where both retention reliability and interface simplicity are mandatory.

FAQ
What is the minimum supply voltage required for data retention in RMLV0416EGBG-4S2#KC0?
The RMLV0416EGBG-4S2#KC0 maintains full data integrity down to 1.5 V VCC under any of three retention activation conditions: CS2 ≤ 0.2V, CS1# ≥ VCC−0.2V (with CS2 high), or simultaneous LB#/UB# ≥ VCC−0.2V. This specification is verified across −40°C to +85°C and enables reliable operation during brown-out events without external backup circuitry.
Does RMLV0416EGBG-4S2#KC0 support true 8-bit access without performance penalty?
Yes, RMLV0416EGBG-4S2#KC0 supports independent upper- and lower-byte access via dedicated UB# and LB# control inputs. Each byte can be read or written in a single 45ns cycle with no timing penalty versus full 16-bit operations - confirmed by AC timing parameters tBA (45ns max) and identical tRC/tWC values for byte and word modes.
Is RMLV0416EGBG-4S2#KC0 pin-compatible with other members of the RMLV0416E family?
RMLV0416EGBG-4S2#KC0 shares identical pinout and ball map with all RMLV0416EGBG-xS2 variants (e.g., #AC0, #KC0), including matching VCC/VSS distribution, address/data placement, and control signal locations. However, it is not pin-compatible with TSOP-44 variants like RMLV0416EGSB-4S2#AA0 due to differing package geometry and terminal count.
What is the maximum operating current of RMLV0416EGBG-4S2#KC0 during active read/write cycles?
The RMLV0416EGBG-4S2#KC0 draws up to 25 mA average operating current (ICC2) under worst-case conditions: 45ns cycle time, 100% duty, and all I/O lines loaded. This value is measured at VCC = 3.0 V and Ta = +25°C per DC Characteristics table - sufficient for most 3.3V microcontroller bus interfaces without additional regulation.
How does the dual chip select architecture (CS1# and CS2) function in RMLV0416EGBG-4S2#KC0?
In RMLV0416EGBG-4S2#KC0, CS1# and CS2 operate independently: CS1# must be low and CS2 high for normal read/write operations; either CS1# high or CS2 low places the device in standby; CS2 additionally gates internal buffers for data retention mode. This allows flexible memory banking, partial disable, and seamless transition to ultra-low-power retention states.
