Product details
Overview
R1LV0816ABG-5SI from Renesas Electronics is an 8Mb low-power static RAM organized as 524,288 words × 16 bits, fabricated in 0.15 µm CMOS/TFT process. It operates from a single 2.4–3.6 V supply, delivers 55 ns access time, and draws only 1.2 µA standby current at 3.0 V - optimized for battery-backed memory systems in portable instrumentation and industrial controllers.
For engineers reviewing the R1LV0816ABG-5SI datasheet, R1LV0816ABG-5SI pinout, R1LV0816ABG-5SI application, or R1LV0816ABG-5SI equivalent, key selection criteria include its f-BGA48 (7.5 mm × 8.5 mm, 0.75 mm pitch) package, TTL-compatible I/O, no-refresh operation, byte-select capability via LB#/UB#, and -40°C to +85°C industrial temperature range.
Technical Context
This advanced LPSRAM implements asynchronous SRAM architecture with dual chip select (CS1#, CS2), independent upper/lower byte enables (UB#, LB#), and three-state bidirectional data I/O (DQ0–DQ15). Its block diagram confirms full address decoding (A0–A18), column/row decoders, sense/write amplifiers, and output buffers - all operating without clocks or refresh cycles.
Operation modes are controlled by combinational logic of CS1#, CS2, WE#, OE#, LB#, and UB#: word read/write requires CS1# low + CS2 high; byte operations activate LB# or UB# low; standby occurs when CS2 is low or both CS1# and CS2 are inactive. Data retention is supported down to 1.5 V with sub-µA current draw.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory capacity | 8 Mbit (524,288 × 16-bit organization) - supports 16-bit data bus interfaces without external width expansion. |
| Access time | 55 ns (max) - enables direct interface with microcontrollers and FPGAs running ≤18 MHz synchronous buses. |
| Supply voltage | 2.4–3.6 V - compatible with 2.5 V and 3.3 V logic domains; eliminates need for level shifters in mixed-voltage systems. |
| Standby current | 1.2 µA typ. at 3.0 V - extends battery life in always-on backup memory applications such as real-time clock modules. |
| Operating temperature | -40°C to +85°C - qualified for industrial-grade embedded systems including PLCs and motor drives. |
| Package | 48-ball f-BGA (7.5 mm × 8.5 mm, 0.75 mm pitch) - reduces PCB area vs. TSOP and improves routing density for compact designs. |
| I/O compatibility | TTL-compatible inputs/outputs - ensures interoperability with legacy 5 V-tolerant microcontrollers and CPLDs using 3.3 V supply. |
Pinout & Package
48-ball fine-pitch BGA (f-BGA) package: PTBG0048HB-A(48FHH), 7.5 mm × 8.5 mm body size, 0.75 mm ball pitch, 6×8 array layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Vcc | Power supply | Primary 2.4–3.6 V supply rail; decoupling required within 5 mm per Renesas layout guidelines. |
| Vss | Ground | Digital ground reference; must be connected to low-impedance PCB plane for noise immunity. |
| A0–A18 | Address input | 19-bit address bus supporting full 512k-word addressing; A18 is MSB for 8 Mb capacity. |
| DQ0–DQ15 | Data I/O | Bidirectional 16-bit data bus; three-state outputs enable OR-tie bus sharing without external transceivers. |
| CS1#, CS2 | Chip select | Two-level hierarchical chip enable: CS1# active-low primary select; CS2 active-high secondary control for power gating and bank isolation. |
| WE#, OE# | Control input | Write Enable (active-low) and Output Enable (active-low) provide standard SRAM timing control; OE# prevents bus contention during read cycles. |
| LB#, UB# | Byte enable | Lower/Upper Byte Enable (active-low) allow 8-bit partial writes without disturbing adjacent bytes - critical for efficient firmware updates and buffer management. |
| NC | No connection | Unbonded balls (A1, C1, G1, H3); must remain unconnected on PCB to avoid signal integrity issues. |
Key Features
| Feature | Design Value |
|---|---|
| No refresh required | Eliminates DRAM controller complexity and periodic refresh overhead - simplifies FPGA-based memory subsystems and reduces firmware footprint. |
| Low-voltage operation | 2.4–3.6 V supply range enables direct integration into battery-powered devices (e.g., handheld meters) without voltage regulation stages. |
| Byte-select capability | Independent LB# and UB# pins support true 8-bit write granularity - avoids read-modify-write sequences and improves write efficiency in embedded OS kernels. |
| TTL-compatible I/O | VIH = 2.2 V min, VIL = 0.4 V max at 3.0 V allows seamless interfacing with legacy 3.3 V microcontrollers (e.g., Renesas RL78, SH-2) without level-shifting circuitry. |
| Data retention mode | Supports 1.5–3.6 V retention voltage with ICCDR ≤ 20 µA at +85°C - maintains SRAM contents during main power loss while minimizing backup battery drain. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV51216AL-10TLI | 10 ns access time, 3.3 V only (3.135–3.465 V), 48-pin TSOP-II package | Higher speed but narrower voltage range and larger footprint; unsuitable for battery-backed or wide-temp designs | Select when system clock exceeds 100 MHz and board space permits TSOP; avoid for low-voltage or extended temperature use. |
| AS6C4008-55PCN | 55 ns access, 2.7–3.6 V, 44-pin SOP package, 1.5 mA typical standby current | Higher standby current and through-hole packaging increase board cost and power in portable systems | Prefer for legacy through-hole assembly or where SOP handling is mandated; not optimal for space-constrained or ultra-low-power designs. |
Compared with IS61LV51216AL-10TLI and AS6C4008-55PCN, the R1LV0816ABG-5SI uniquely balances 55 ns speed, 2.4 V minimum supply, 1.2 µA standby, and compact f-BGA - making it the only choice for battery-backed industrial controllers requiring both performance and energy efficiency in minimal area.

FAQ
What is the maximum access time specification for the R1LV0816ABG-5SI?
The R1LV0816ABG-5SI has a maximum access time of 55 ns under recommended operating conditions (Vcc = 2.4–3.6 V, Ta = -40°C to +85°C). This value applies when Vcc is ≥2.7 V; if Vcc is 2.4–2.7 V, the 70 ns specification of the -7SI variant governs. The 55 ns figure ensures reliable interface timing with microcontrollers and FPGAs operating up to 18 MHz.
Does the R1LV0816ABG-5SI require a refresh circuit?
No, the R1LV0816ABG-5SI is a static RAM and does not require any refresh circuitry. Its CMOS latch-based memory cells retain data as long as power is applied, eliminating the need for external refresh controllers, timers, or associated firmware overhead - a key advantage over DRAM in resource-constrained embedded systems.
What is the function of the CS2 pin on the R1LV0816ABG-5SI?
The CS2 pin on the R1LV0816ABG-5SI is an active-high secondary chip select that works in conjunction with CS1# (active-low) to define operational states. When CS2 is low, the device enters standby mode regardless of CS1# state; when CS2 is high and CS1# is low, normal read/write operations occur. CS2 also controls internal buffers during data retention.
Can the R1LV0816ABG-5SI operate from a 2.5 V supply?
Yes, the R1LV0816ABG-5SI is fully specified to operate from 2.4 V to 3.6 V, so 2.5 V is within its valid supply range. At 2.5 V, timing parameters default to the 70 ns specifications of the R1LV0816ABG-7SI variant per the datasheet note - meaning tAA, tRC, and other AC characteristics are relaxed to ensure robust operation at lower voltage.
What package type is used for the R1LV0816ABG-5SI?
The R1LV0816ABG-5SI uses a 48-ball fine-pitch ball grid array (f-BGA) package designated PTBG0048HB-A(48FHH), with dimensions of 7.5 mm × 8.5 mm and a 0.75 mm ball pitch. This compact surface-mount package supports high-density PCB layouts and improved thermal dissipation compared to TSOP or SOP alternatives.
