Product details
Overview
71V016SA15BF from Renesas Electronics is a 64K × 16-bit (1 Mbit), 3.3V CMOS static RAM with 15 ns read/write cycle time, industrial temperature range (–40°C to +85°C), and LVTTL-compatible I/O for embedded control and data buffering in FPGA/ASIC-based systems.
For engineers reviewing the 71V016SA15BF datasheet, 71V016SA15BF pinout, 71V016SA15BF application, or 71V016SA15BF equivalent, key selection factors include byte-enable support, FBGA-48 package compatibility, low-power standby current (35 mA), and guaranteed tAA ≤ 15 ns at VDD = 3.15–3.6 V.
Technical Context
This device implements fully static asynchronous operation-no clocks or refresh required-and uses dual-byte enable (BHE/ BLE) to support 8-bit sub-word access within the 16-bit data bus. Its architecture includes independent address buffers, sense amps, and write drivers optimized for deterministic timing across commercial and industrial grades.
All inputs (A0–A15, CS, OE, WE, BHE, BLE) are LVTTL-compatible with VIH ≥ 2.0 V and VIL ≤ 0.8 V; outputs drive ±4 mA/±8 mA loads while maintaining VOL ≤ 0.4 V and VOH ≥ 2.4 V under min VDD conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576-bit total); supports word-level random access without refresh. |
| Access Time (tAA) | ≤15 ns max; ensures valid data output within 15 ns of address assertion at VDD = 3.15–3.6 V. |
| Cycle Time (tRC) | 15 ns max; defines minimum interval between successive read/write operations. |
| Supply Voltage | 3.15–3.6 V; single-rail 3.3V system compatibility with ±5% tolerance. |
| Operating Temperature | –40°C to +85°C; qualified for industrial-grade reliability in harsh environments. |
| Standby Current (ISB) | 35 mA max; enables low-power hold mode when CS ≥ VHC and no address transitions occur. |
| I/O Interface | LVTTL-compatible bidirectional data bus (I/O0–I/O15); eliminates level-shifting in 3.3V logic systems. |
Pinout & Package
71V016SA15BF is packaged in a 48-ball plastic FBGA (BFG48), 7 mm × 7 mm, 0.8 mm ball pitch, JEDEC MO-276 compliant. Pinout validated per Renesas datasheet Figure 3834 drw 02 (FBGA top view) and Table 3834 tbl 01.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit row/column select lines; fully static-no setup/hold timing required beyond tAS = 0 ns. |
| CS | Chip Select | Active-low global enable; controls device power state and output impedance (High-Z when high). |
| OE | Output Enable | Active-low read gate; allows output control independent of CS for bus sharing. |
| WE | Write Enable | Active-low write strobe; initiates write cycle with tWP ≥ 10 ns minimum pulse width. |
| BHE / BLE | Byte Enable | Independent high/low byte gating; enables 8-bit writes without disturbing adjacent byte. |
| I/O0–I/O15 | Bidirectional Data | 16-bit LVTTL I/O; auto-directional based on WE/OE states; supports concurrent read/write isolation. |
| VDD / VSS | Power / Ground | Single 3.3V supply pair; decoupling required per ball location to meet ICC transient demands. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-byte write enable | Enables selective 8-bit updates to upper (I/O8–I/O15) or lower (I/O0–I/O7) byte without full-word overwrite. |
| Asynchronous static operation | No clock, no refresh, no wait states-simplifies timing-critical control logic and reduces system overhead. |
| Industrial temperature qualification | Guaranteed 15 ns performance across –40°C to +85°C, supporting extended-life industrial deployments. |
| Low-impedance LVTTL I/O | Direct interface to FPGAs, microcontrollers, and ASICs operating at 3.3V without external translators. |
| Dynamic standby current | 35 mA max at fMAX; reduces idle power in battery-backed or energy-sensitive applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-15ZSXI | 512K × 16-bit (8 Mbit), 15 ns, 3.3V; larger density but same FBGA-48 footprint and pinout. | Higher capacity suits systems requiring >1 Mbit cache; identical timing and voltage simplify drop-in upgrade path. | Select when future scalability or multi-frame buffering is needed without PCB redesign. |
| IS61LV25616AL-15TQLI | 256K × 16-bit (4 Mbit), 15 ns, 3.3V; TSOP-44 package only-no FBGA option. | Requires board layout change due to different package; suitable where space constraints favor SOJ/TSOP over FBGA. | Choose for cost-sensitive industrial designs where FBGA assembly infrastructure is unavailable. |

FAQ
What is the maximum operating frequency supported by the 71V016SA15BF?
The 71V016SA15BF does not operate on a clock signal-it is an asynchronous SRAM. Its maximum effective throughput is governed by its 15 ns cycle time (tRC), enabling up to 66.7 million operations per second in ideal conditions. This value is guaranteed across the full industrial temperature range (–40°C to +85°C) and supply voltage range (3.15–3.6 V).
Does the 71V016SA15BF require external refresh circuitry?
No, the 71V016SA15BF is a fully static RAM and requires no refresh circuitry. Its internal latches retain data indefinitely as long as VDD remains within specification and CS is held active or the device remains in standby. This eliminates refresh overhead in microcontroller or FPGA-based systems.
Can the 71V016SA15BF be used with 5V logic interfaces?
No-the 71V016SA15BF is strictly a 3.3V LVTTL device. Its absolute maximum input voltage is VDD + 0.5 V (≤4.1 V), and VIH is specified as ≥2.0 V-not compatible with 5V TTL thresholds. Interfacing with 5V systems requires level translation, such as TI SN74AVC4T245 or similar bidirectional translators.
What is the meaning of "BFGI8" in the ordering code 71V016SA15BFGI8?
In 71V016SA15BFGI8, "BF" denotes FBGA-48 package, "G" indicates green (lead-free/RoHS-compliant) construction, "I" specifies industrial temperature grade (–40°C to +85°C), and "8" means tape-and-reel packaging. The base part 71V016SA15BF shares identical electrical specs but differs in packaging and environmental compliance.
Is the 71V016SA15BF pin-compatible with earlier IDT71V016 variants like the 71V016SA10BF?
Yes-the 71V016SA15BF is pin-compatible with all members of the IDT71V016SA family in the same package variant (e.g., BFG48). Address, data, control pins, and power terminals match exactly; only timing parameters differ (e.g., tAA = 15 ns vs. 10 ns). No PCB changes are required when upgrading speed grades within the same package.
