Product details
Overview
71V016SA10BFGI from Renesas Electronics is a 64K × 16-bit (1 Mbit), 3.3 V high-speed CMOS static RAM with 10 ns access time, industrial temperature range (–40°C to +85°C), LVTTL-compatible I/O, and byte-enable control - used in real-time embedded controllers, network packet buffers, and FPGA configuration memory.
For engineers reviewing the 71V016SA10BFGI datasheet, 71V016SA10BFGI pinout, 71V016SA10BFGI application, or 71V016SA10BFGI equivalent, key selection criteria include tAA ≤ 10 ns, industrial-grade reliability, FBGA-48 package compatibility, and dual-byte write enable support for legacy bus interfacing.
Technical Context
This device implements fully static asynchronous circuitry-no clocks or refresh required-and uses high-reliability CMOS technology optimized for low-latency random-access operation. Its architecture includes independent upper/lower byte enable (BHE/BLE) logic, output enable (OE) with 5 ns response, and chip select (CS) with 10 ns access timing.
The 71V016SA10BFGI supports three distinct write control modes (WE-, CS-, or BHE/BLE-controlled), each with defined setup/hold and pulse-width requirements. All I/Os are bidirectional and LVTTL-compatible, operating from a single 3.3 V supply with VIH = 2.0 V min and VIL = 0.8 V max.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Power Consumption | ISB1 = 10 mA max in full standby - supports low-power sleep modes in portable instrumentation |
Pinout & Package
71V016SA10BFGI is housed in a 48-ball plastic FBGA (BFG48) package, 7 mm × 7 mm, 0.8 mm pitch, JEDEC MO-276 compliant, with bottom-side solder ball layout optimized for high-density PCB routing and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus supporting 64K-word addressing; TTL-level compatible |
| I/O0–I/O7 | Low-Byte Data I/O | Bidirectional 8-bit data path enabled by BLE; LVTTL voltage levels |
| I/O8–I/O15 | High-Byte Data I/O | Bidirectional 8-bit data path enabled by BHE; independent of low-byte control |

| VDD | Power Supply | +3.3 V supply pin; two dedicated pins (pins D5, E1) reduce IR drop |
| VSS | Ground | Ground reference; four dedicated pins (pins D4, E4, E5, F1) improve noise immunity |
| NC | No Connect | Unbonded pads (pins A1, C1, G1, H1, H2, H6); must be left floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| 10 ns access time at industrial temperature | Guaranteed tAA ≤ 10 ns over –40°C to +85°C - eliminates timing margin uncertainty in harsh environments |
| Dual independent byte enables (BHE/BLE) | Enables true 8-bit or 16-bit writes without external byte-mask logic - reduces gate count in MCU/FPGA interfaces |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-10ZSXI | 1 Mbit (64K × 16), 10 ns, 3.3 V, SOIC-44 package; no BHE/BLE - uses OE-only byte control | Lacks independent high/low byte write enables; requires external logic for partial-word writes | Preferred where board space permits SOIC and byte masking is handled in FPGA logic |

FAQ
What is the maximum operating frequency supported by the 71V016SA10BFGI?
The 71V016SA10BFGI is an asynchronous SRAM with no internal clock; its effective maximum operating frequency depends on system-level timing. With tRC = 10 ns, it supports up to 100 MHz continuous read/write cycling when interfaced to a controller capable of meeting all setup/hold requirements. Actual achievable bandwidth is governed by tAA, tWC, and bus protocol overhead-not a fixed clock frequency.
Does the 71V016SA10BFGI require refresh circuitry or periodic memory maintenance?
No, the 71V016SA10BFGI is a fully static RAM and requires no refresh cycles, clocks, or periodic maintenance. Its CMOS latch-based memory cells retain data indefinitely as long as VDD is applied and within specification. This eliminates refresh-related timing complexity and power spikes common in DRAM-based systems.
Can the 71V016SA10BFGI be used with 5 V logic interfaces?
No - the 71V016SA10BFGI is strictly a 3.3 V device with LVTTL-compatible I/O (VIH = 2.0 V min, VIL = 0.8 V max). Direct connection to 5 V logic violates absolute maximum ratings and risks damage. Level translation (e.g., TXB0108 or discrete MOSFET translators) is mandatory for interoperability with 5 V systems.
What is the meaning of "BFGI" in the part number 71V016SA10BFGI?
In 71V016SA10BFGI, "BF" denotes the 48-ball CABGA package type (BFG48), "G" indicates green (lead-free, RoHS-compliant) construction, and "I" specifies industrial temperature grade (–40°C to +85°C). The "10" denotes 10 ns access time, and "SA" identifies the 3.3 V core voltage variant of the IDT71V016 family.
Is the 71V016SA10BFGI pin-compatible with other speed grades in the same package?
Yes - all 71V016SAxxBFGI variants (10/12/15/20 ns) share identical pinout, package footprint, and electrical interface. Speed grade differences affect only timing parameters (tAA, tRC, etc.), not connectivity or DC characteristics. This enables drop-in timing upgrades or mixed-speed BOM optimization without PCB redesign.
