Product details
Overview
71V016SA15BFI from Renesas Electronics is a 64K × 16-bit (1 Mbit), 3.3 V CMOS static RAM with 15 ns access time, industrial temperature range (–40°C to +85°C), LVTTL-compatible I/O, and dual byte enable (BHE/ BLE) for flexible data bus control in embedded memory subsystems.
For engineers reviewing the 71V016SA15BFI datasheet, 71V016SA15BFI pinout, 71V016SA15BFI application, or 71V016SA15BFI equivalent, key selection considerations include its FBGA-48 (BF48) package, 3.3 V single-supply operation, asynchronous static architecture requiring no clocks or refresh, and support for word/byte-level read/write cycles.
Technical Context
The 71V016SA15BFI implements a fully static asynchronous memory architecture with no internal clocks or refresh circuitry. Its address decoding, sense amplifiers, and write drivers are all CMOS-based, enabling deterministic timing across the full industrial temperature range.
It supports three independent write enable modes-chip-select-controlled, output-enable-controlled, and byte-enable-controlled-with guaranteed tWP (write pulse width) of 10 ns and tDW (data valid to end of write) of 7 ns at VDD min., ensuring robust timing margin in high-speed microcontroller and FPGA interface designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576 bits); supports 16-bit parallel data bus with byte-select capability |
| Access Time (tAA) | 15 ns max; defines minimum delay from valid address to stable data output under industrial conditions |
| Supply Voltage | 3.15 V to 3.6 V; single 3.3 V rail compatible with LVTTL logic families |
| Operating Temperature | –40°C to +85°C; qualified for industrial-grade reliability without derating |
| Dynamic Current (ICC) | 130 mA max at fMAX; enables low-power system design when paired with controlled CS/OE assertion |
| Standby Current (ISB1) | 10 µA max (static); allows ultra-low power retention during extended idle periods |
| I/O Interface | LVTTL-compatible bidirectional data pins (I/O0–I/O15); eliminates level-shifter requirements in 3.3 V systems |
Pinout & Package
71V016SA15BFI is packaged in a 48-ball plastic FBGA (BF48, 7 mm × 7 mm, 0.8 mm pitch), JEDEC-compliant with bottom-side ball layout optimized for high-density PCB routing and thermal performance in industrial controllers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus; selects one of 64K memory locations; fully static-no setup/hold required |
| CS | Chip Select | Active-low enable; places device in active or standby mode; controls tACS (15 ns max) and tCLZ (5 ns) |
| OE | Output Enable | Active-low; gates output drivers only; enables fast 7 ns tOE while preserving address stability |
| WE | Write Enable | Active-low; initiates write cycle; determines tWP (10 ns min) and tDW (7 ns min) timing constraints |
| BHE / BLE | Byte Enable | Independent high/low byte controls; permits 8-bit writes without affecting opposite byte (e.g., I/O8–I/O15 or I/O0–I/O7) |
| I/O0–I/O15 | Bidirectional Data | 16-bit LVTTL I/O; tristated when CS high or OE high; supports concurrent read/write on separate bytes |
| VDD / VSS | Power / Ground | Single 3.3 V supply pair; decoupling required per JEDEC FBGA guidelines to maintain signal integrity |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXI | 45 ns access time; 512K × 16 organization; 3.3 V core but 2.5 V I/O tolerant; TSOP-44 only | Lower speed and larger density-suited for cost-sensitive, non-real-time buffering where latency <20 ns is not required | Select when board space permits TSOP and system timing budget allows ≥45 ns access |

FAQ
What is the maximum operating frequency supported by the 71V016SA15BFI?
The 71V016SA15BFI does not operate on a clock; it is an asynchronous SRAM. Its maximum effective throughput is determined by its 15 ns access time and 15 ns cycle time (tRC), supporting up to ~66.7 MHz random read/write operations on a 16-bit bus. Timing margins must be verified against system-level setup/hold requirements using the AC parameters in the Renesas datasheet.
Does the 71V016SA15BFI require external refresh circuitry?
No, the 71V016SA15BFI is a fully static RAM and requires no refresh circuitry or clocks. Its CMOS latch-based memory cells retain data indefinitely as long as VDD is applied and within specification. This eliminates refresh overhead and simplifies integration with microcontrollers, FPGAs, and ASICs lacking dedicated DRAM controllers.
Can the 71V016SA15BFI be used with 5 V logic systems?
No-the 71V016SA15BFI is strictly a 3.3 V LVTTL device. Its absolute maximum input voltage is VDD + 0.5 V (≤4.1 V), and VIH is specified as ≥2.0 V. Direct connection to 5 V logic may damage the part or cause unreliable operation. Level translation (e.g., TXB0108) is required for interoperability with 5 V buses.
What is the meaning of "BFI" in the part number 71V016SA15BFI?
In the ordering code 71V016SA15BFI, "BFI" denotes the BF48 CABGA package (BF) with industrial temperature grade (I). The "BFI" suffix confirms the device is supplied in a 48-ball, 7 mm × 7 mm FBGA and qualified for operation from –40°C to +85°C-critical for deployment in harsh-environment applications.
Is the 71V016SA15BFI RoHS compliant and halogen-free?
Yes-the 71V016SA15BFI is a green-part designation (per Renesas ordering information), meaning it complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and bromine/chlorine content is below 900 ppm.
