Product details
Overview
71V016SA20BFGI from Renesas Electronics is a 64K × 16-bit (1 Mbit), 3.3 V CMOS static RAM with 20 ns read/write cycle time, industrial temperature range (–40°C to +85°C), and FBGA-48 (BFG48) package. It features LVTTL-compatible bidirectional I/Os, separate high/low byte enables (BHE/BLE), and single-supply operation - deployed in real-time industrial controllers, legacy bus-based instrumentation, and FPGA configuration memory buffers.
For engineers reviewing the 71V016SA20BFGI datasheet, 71V016SA20BFGI pinout, 71V016SA20BFGI application, or 71V016SA20BFGI equivalent, key selection criteria include its 20 ns access timing under industrial conditions, FBGA-48 footprint compatibility, byte-select capability for 8-bit subsystem interfacing, and low dynamic standby current (30 mA max at 20 ns).
Technical Context
The 71V016SA20BFGI implements fully static asynchronous circuitry-no clocks or refresh required-and uses high-reliability CMOS technology optimized for deterministic timing across –40°C to +85°C. Its dual-byte enable architecture allows independent 8-bit data access on I/O0–I/O7 (low byte) and I/O8–I/O15 (high byte), supporting mixed-width bus systems without external logic.
Timing is controlled via three independent enable paths: chip select (CS), output enable (OE), and write enable (WE), each with defined setup/hold and transition-to-valid delays (e.g., tACS = 20 ns max, tOE = 8 ns max). All inputs meet LVTTL voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and outputs drive ±4 mA/±8 mA loads while maintaining VOL ≤ 0.4 V and VOH ≥ 2.4 V at VDD = 3.15 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus; selects one of 64K locations; no internal latching - requires stable address during CS low |

| OE | Output Enable | Active-low read control; enables I/O drivers only when CS and WE are inactive; tOE = 8 ns max |
| WE | Write Enable | Active-low write strobe; controls direction and data capture; tWP = 12 ns min ensures reliable write setup |
| BHE / BLE | Byte Enable Inputs | Active-low controls upper (I/O8–I/O15) or lower (I/O0–I/O7) byte; enables 8-bit access without external demux |
| I/O0–I/O15 | Bidirectional Data | 16-bit LVTTL I/O bus; tristated when CS high or OE high; VOL ≤ 0.4 V at 8 mA sink |
| VDD | Power Supply | 3.3 V core supply; two dedicated balls (D5, E1) reduce IR drop and switching noise |
| VSS | Ground | Ground reference; four dedicated balls (D4, E2, F1, G3) ensure low-impedance return path |

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 |

FAQ
What is the maximum operating frequency supported by the 71V016SA20BFGI?
The 71V016SA20BFGI does not operate on a clock but supports asynchronous bus cycles up to 50 MHz, derived from its 20 ns read/write cycle time (tRC = 20 ns max). This enables full 16-bit word transfers every 20 ns without clock synchronization, making it ideal for microcontroller and FPGA parallel interfaces with tight timing budgets.
Does the 71V016SA20BFGI require external refresh circuitry?
No, the 71V016SA20BFGI is a fully static RAM and requires no refresh cycles or external refresh circuitry. Its CMOS latch-based memory cells retain data indefinitely as long as VDD is applied and CS remains asserted - simplifying system design versus DRAM or pseudo-SRAM solutions.
Can the 71V016SA20BFGI be used in a 16-bit bus system with 8-bit peripherals?
Yes, the 71V016SA20BFGI supports this directly via its dedicated BHE (high byte enable) and BLE (low byte enable) inputs. These allow independent activation of I/O8–I/O15 or I/O0–I/O7, enabling seamless connection to 8-bit UARTs, ADCs, or legacy controllers without external multiplexers or bus transceivers.
What is the FBGA-48 (BFG48) package dimension and soldering profile for the 71V016SA20BFGI?
The 71V016SA20BFGI uses a 7 mm × 7 mm, 48-ball plastic FBGA (BFG48) with 0.8 mm ball pitch and JEDEC MO-276AC mechanical compliance. Recommended reflow profile follows IPC-J-STD-020D for moisture sensitivity level 3 (MSL3), peak temperature 260°C, and ramp rates per standard Pb-free guidelines.
Is the 71V016SA20BFGI RoHS-compliant and halogen-free?
Yes, the 71V016SA20BFGI is a green-part designation ('G' in ordering code) and complies with RoHS Directive 2011/65/EU and JEDEC JS709E halogen-free requirements. Lead-free (Pb-free) terminations and bromine/chlorine-free molding compound are confirmed in Renesas' official material declarations.
