Product details
Overview
71V016SA20BFG from Renesas Electronics is a 3.3V, 64K × 16-bit (1 Mbit) high-speed CMOS static RAM with 20 ns read/write cycle time, industrial temperature range (–40°C to +85°C), and LVTTL-compatible I/O. It features separate byte enable (BHE/BLE), output enable (OE), and chip select (CS) for flexible memory access in embedded controllers and networking buffers.
For engineers reviewing the 71V016SA20BFG datasheet, 71V016SA20BFG pinout, 71V016SA20BFG application, or 71V016SA20BFG equivalent, key selection criteria include its 20 ns tRC timing, FBGA-48 (BFG48) package, 3.3V single-supply operation, and industrial-grade reliability for real-time data buffering in telecom infrastructure and industrial PLCs.
Technical Context
The 71V016SA20BFG implements fully static asynchronous circuitry-no clocks or refresh required-and uses high-reliability CMOS technology optimized for low-power standby (ISB1 = 10 mA max) and dynamic operation (ICC = 120 mA max at 20 ns). Its dual-byte enable architecture supports independent 8-bit accesses to upper and lower data words.
Timing is controlled via three independent enable paths: CS-controlled, OE-controlled, and BHE/BLE-controlled write cycles, each with defined setup/hold and transition parameters (e.g., tAS = 0 ns, tDH = 0 ns). All inputs and outputs are LVTTL-compatible with VIH(min) = 2.0 V and VIL(max) = 0.8 V at VDD = 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576-bit total); enables word-level 16-bit data transfers without external multiplexing |
| Access/Cycle Time | 20 ns (tRC, tAA); guarantees deterministic latency for real-time buffer applications |
| Supply Voltage | 3.15–3.6 V; compatible with standard 3.3V logic rails and tolerant of ±5% regulation variation |
| Operating Temperature | –40°C to +85°C; qualified for industrial environments including factory automation and base station equipment |
| Package | 48-ball plastic FBGA (BFG48, 7 mm × 7 mm); supports high-density PCB layouts with fine-pitch routing |
| Input/Output Interface | LVTTL-compatible (VIH ≥ 2.0 V, VIL ≤ 0.8 V); ensures interoperability with FPGA I/O banks and microcontroller GPIOs |

Pinout & Package
71V016SA20BFG is housed in a JEDEC-standard 48-ball plastic FBGA (BFG48) package with 0.8 mm ball pitch and bottom-side thermal pad. Pinout follows Renesas' BF48/BFG48 footprint, supporting automated assembly and thermal dissipation in compact modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus; selects one of 64K memory locations; no internal latching required |
| I/O0–I/O7 | Low-Byte Data I/O | Bidirectional 8-bit data path enabled by BLE; supports partial-word writes without disturbing high byte |
| I/O8–I/O15 | High-Byte Data I/O | Bidirectional 8-bit data path enabled by BHE; allows independent access to upper/lower bytes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed parallel SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-20BVXI | 512K × 16-bit (8 Mbit), 20 ns, 3.3V; same BFG48 package but larger density and higher ICC (145 mA) | Higher capacity suits longer burst buffers; increased power draw limits use in thermally constrained modules | Select when >1 Mbit capacity is required and board layout accommodates identical footprint |
| IS61LV25616AL-20TQLI | 256K × 16-bit (4 Mbit), 20 ns, 3.3V; TSOP-44 package, not FBGA; tAA = 20 ns (vs. 71V016SA20BFG's 20 ns tRC) | TSOP form factor eases hand-soldering and prototyping but lacks thermal performance of FBGA for sustained writes | Prefer for cost-sensitive industrial designs where FBGA reflow capability is unavailable |
Compared with CY62167EV30LL-20BVXI and IS61LV25616AL-20TQLI, the 71V016SA20BFG delivers optimal balance of density, package efficiency, and industrial qualification-making it ideal for space-constrained, thermally demanding applications where 1 Mbit suffices and FBGA integration is preferred.

FAQ
What is the operating voltage range for the 71V016SA20BFG?
The 71V016SA20BFG operates from 3.15 V to 3.6 V DC. This 3.3V nominal supply range ensures compatibility with standard LVTTL logic families and accommodates typical power rail tolerances in industrial and telecom systems. Operation outside this range may cause functional failure or accelerated wear.
Does the 71V016SA20BFG require a clock or refresh signal?
No, the 71V016SA20BFG is a fully static asynchronous SRAM and requires neither a clock nor periodic refresh. Its internal circuitry retains data indefinitely as long as power is applied and CS remains asserted, simplifying system design and eliminating timing-critical refresh overhead.
What is the meaning of the 'BFG' suffix in 71V016SA20BFG?
The 'BFG' suffix in 71V016SA20BFG denotes the 48-ball plastic FBGA package (BFG48) with lead-free, RoHS-compliant construction and halogen-free molding compound. It distinguishes this variant from SOJ (YG) and TSOP (PHG) versions and confirms mechanical and thermal compatibility with Renesas' BF48 footprint.
Can the 71V016SA20BFG perform simultaneous read and write operations?
No, the 71V016SA20BFG does not support true simultaneous read/write. It is a single-port SRAM: any write cycle (initiated by WE low) disables outputs (puts I/O pins in high-Z) until completion. Read and write operations must be sequenced using CS, OE, and WE controls per the truth table in the datasheet.
Is the 71V016SA20BFG qualified for industrial temperature operation?
Yes, the 71V016SA20BFG is explicitly rated for –40°C to +85°C operation, as confirmed in the "Orderable Part Information" table and Absolute Maximum Ratings section. This qualification applies across all AC and DC specifications at the 20 ns speed grade, making it suitable for deployment in uncontrolled industrial environments.
