Product details
Overview
R1LV0416DBG-7LI#S0 from Renesas Electronics is a 4-Mbit static RAM organized as 256-kword × 16-bit, fabricated in 0.15 µm CMOS/TFT process, operating from a single 3.0 V supply (2.7–3.6 V), with 70 ns max access time and −40 to +85°C industrial temperature range - used for nonvolatile data retention in battery-backed embedded controllers and real-time data buffers.
For engineers reviewing the R1LV0416DBG-7LI#S0 datasheet, R1LV0416DBG-7LI#S0 pinout, R1LV0416DBG-7LI#S0 application, or R1LV0416DBG-7LI#S0 equivalent, this page delivers verified package mapping (48-ball CSP, PTBG0048HB-A), byte-selectable I/O architecture, low-power standby operation (10 µA typ at +25°C), and battery backup mode support via dual chip select control.
Technical Context
The R1LV0416DBG-7LI#S0 implements a 2,048 × 2,048 memory matrix with full row/column decoding, supporting independent upper/lower byte access via UB#/LB# control and three-state bidirectional I/Os (I/O0–I/O15). Its control logic enables simultaneous CS1#/CS2-driven standby entry and data retention mode activation at VCC ≥ 2.0 V.
It features common data I/O with output enable (OE#) and write enable (WE#) synchronized to address and chip select transitions, ensuring deterministic read/write timing under varying VCC (2.7–3.6 V) and temperature (−40 to +85°C). Standby current scales with ambient temperature: 10 µA typ at +25°C, 1 µA typ at +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4 Mbit (256 kwords × 16 bits) - supports 512 kB of word-accessible SRAM in compact footprint |
| Access Time | 70 ns max - defines minimum cycle time for reliable read/write in high-speed microcontroller interfaces |
| Supply Voltage | 2.7 V to 3.6 V - compatible with 3.3 V system rails and tolerant of brown-out conditions down to 2.0 V for data retention |
| Standby Current | 10 µA typ at +25°C - enables multi-year battery backup in portable instrumentation and metering systems |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade embedded applications without derating |

Pinout & Package
Package: 48-ball fine-pitch ball grid array (CSP), PTBG0048HB-A, 0.75 mm ball pitch, top-side marking includes R1LV0416DBG-7LI#S0 and lot code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address input | 18-bit address bus selecting one of 256k words; A0–A17 fully decoded for direct linear addressing |
| I/O0–I/O7 | Data I/O (lower byte) | Bidirectional 8-bit data path enabled by LB#; three-state when LB# or OE# inactive |

| CS1#, CS2 | Chip select inputs | Dual active-low selects: CS1# primary enable; CS2 secondary for standby/retention mode entry |
| OE#, WE# | Output and write enable | OE# controls output drivers only; WE# gates write cycles - both referenced to VIH/VIL thresholds (2.2 V / 0.6 V) |
| UB#, LB# | Byte select controls | Independent upper/lower byte gating - enables 8-bit partial writes while preserving other byte contents |
| VCC, VSS | Power and ground | Single 3.3 V supply domain; decoupling required per Renesas layout guidelines due to fast switching currents |
| NC | No connection | Three unconnected balls (A1, D1, F6) - must be left floating or grounded per PCB design rules; not internally bonded |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25616AL-7TLI | Same density (256k × 16), 70 ns access, but 44-pin TSOP-II package (not BGA); higher ISB (20 µA typ) | Larger footprint; less suitable for ultra-compact designs; no fine-pitch BGA assembly compatibility | Select when board space permits TSOP and legacy reflow profiles are used |
| AS6C4008-70TIN | 4-Mbit × 8-bit organization (not ×16); 70 ns access; 32-pin SOP; 15 µA ISB typ | Requires external byte multiplexing for 16-bit interface; incompatible pinout and data width | Choose only if system uses 8-bit data bus or requires SOP packaging for manual repair |
Compared with IS61LV25616AL-7TLI and AS6C4008-70TIN, the R1LV0416DBG-7LI#S0 provides superior space efficiency via 48-ball CSP, lower standby current for extended battery life, and native 16-bit interface eliminating glue logic - making it optimal for next-generation compact industrial and medical electronics.

FAQ
What is the maximum operating frequency supported by R1LV0416DBG-7LI#S0?
The R1LV0416DBG-7LI#S0 does not specify a clock frequency because it is an asynchronous SRAM. Its performance is defined by access time (70 ns max) and cycle time (70 ns max), enabling reliable operation with bus clocks up to ~14 MHz in systems where address/data setup/hold times are met. The R1LV0416DBG-7LI#S0 achieves this using standard control signals (CS1#, WE#, OE#, UB#, LB#) without internal clocking.
Does R1LV0416DBG-7LI#S0 support true 16-bit parallel data access?
Yes, the R1LV0416DBG-7LI#S0 natively supports full 16-bit parallel access via I/O0–I/O15. Unlike ×8 devices requiring external multiplexing, this SRAM delivers true word-wide reads/writes. Upper and lower bytes can also be accessed independently using UB# and LB# - allowing efficient 8-bit operations without disturbing adjacent data.
How does R1LV0416DBG-7LI#S0 enter battery backup mode?
The R1LV0416DBG-7LI#S0 enters battery backup (data retention) mode when either CS2 is driven low (≤0.2 V), or CS1# is held high (≥VCC − 0.2 V) while CS2 is high, or both UB# and LB# are high while CS2 is high and CS1# is low. In this state, current drops to ≤10 µA at +25°C, preserving data down to VCC = 2.0 V - confirmed in the Low VCC Data Retention Characteristics section of the datasheet.
Is R1LV0416DBG-7LI#S0 pin-compatible with other devices in the R1LV0416D Series?
No - R1LV0416DBG-7LI#S0 uses a 48-ball CSP package (PTBG0048HB-A), while R1LV0416DSB-7LI uses a 44-pin TSOP-II (PTSB0044GA-A). Pin functions are identical across the series, but physical layout, ball/pad count, and pitch differ. Direct PCB replacement requires redesign; however, logic-level interface behavior remains consistent for software and timing validation.
What is the meaning of the "#S0" suffix in R1LV0416DBG-7LI#S0?
The "#S0" suffix in R1LV0416DBG-7LI#S0 denotes Renesas's standard tape-and-reel packaging option: 1,000 units per reel, 12 mm tape width, and EIA-481-D compliant carrier. It indicates factory-standard shipping configuration - not a functional variant. All electrical, thermal, and timing specifications match the base R1LV0416DBG-7LI part number as defined in Rev.1.00 of the datasheet.
