Product details
Overview
71V016SA15BFG from Renesas Electronics is a 1 Mbit (64K × 16) high-speed CMOS static RAM with 15 ns access time, single 3.3 V supply operation, industrial temperature range (–40°C to +85°C), and LVTTL-compatible bidirectional I/O. It serves as fast, non-refreshing data storage in embedded controllers, network packet buffers, and real-time DSP subsystems.
For engineers reviewing the 71V016SA15BFG datasheet, 71V016SA15BFG pinout, 71V016SA15BFG application, or 71V016SA15BFG equivalent, key selection criteria include byte-enable-controlled 16-bit word access, 48-ball FBGA (BFG48) packaging, low-power standby current (35 mA max), and guaranteed tAA ≤ 15 ns across industrial conditions.
Technical Context
This device implements fully static asynchronous logic-no clocks or refresh required-and uses dual byte enable (BHE/ BLE) for independent high- and low-byte access. Its architecture supports simultaneous chip select (CS), output enable (OE), and write enable (WE) control with overlapping timing windows for read/write cycle flexibility.
All inputs and outputs are LVTTL-compatible with VIH ≥ 2.0 V and VIL ≤ 0.8 V at VDD = 3.3 V; dynamic operating current is rated at 130 mA max (industrial grade), and full standby current is only 10 mA. The 71V016SA15BFG operates without external timing components and maintains valid data hold (tOH = 4 ns) during address transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1,048,576 bits (64K × 16), enabling compact 16-bit data bus interfacing without external multiplexing. |
| Access Time (tAA) | ≤15 ns (industrial temp), ensuring compatibility with 66 MHz system buses requiring sub-16 ns memory response. |
| Supply Voltage | 3.3 V ±0.15 V (3.15–3.6 V), compatible with standard LVTTL logic domains and eliminating level-shifting needs. |
| Operating Temperature | –40°C to +85°C, qualified for industrial-grade reliability in base stations, motor drives, and factory automation. |
| Package | 48-ball plastic FBGA (BFG48, 7 mm × 7 mm), supporting high-density PCB layouts and automated SMT assembly. |
| Byte Enable Control | Dedicated BHE and BLE pins allow selective 8-bit writes without disturbing adjacent byte lanes-critical for protocol stack buffering. |
| Standby Current (ISB) | 35 mA max (industrial), enabling low-power sleep modes in battery-backed or energy-sensitive systems. |
Pinout & Package
71V016SA15BFG is housed in a 48-ball plastic FBGA (BFG48) package per JEDEC MO-276AB, with 0.8 mm ball pitch and bottom-side thermal pad. Pin mapping follows standard 71V016SA family layout, verified for BFG48 variant in Renesas datasheet Figure 3834 drw 02 and Table 3834 tbl 01.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus interface; fully static-no setup/hold timing constraints on address stability during CS active. |
| CS | Chip Select | Active-low enable controlling overall device activation; tACS ≤ 15 ns ensures rapid bank selection in multi-SRAM systems. |
| OE | Output Enable | Active-low control of output drivers; tOE ≤ 7 ns enables precise gating of data onto shared buses without contention. |
| WE | Write Enable | Active-low write strobe; tWP ≥ 10 ns minimum pulse width ensures reliable latch capture in synchronous write protocols. |
| BHE / BLE | Byte Enable Inputs | Independent high-/low-byte gating-enables 8-bit microcontroller interfacing or partial-word updates without read-modify-write cycles. |
| I/O0–I/O15 | Bidirectional Data I/O | LVTTL-compatible 16-bit data bus; high-impedance state when CS, OE, or byte enables inactive-prevents bus conflicts. |
| VDD / VSS | Power / Ground | Single 3.3 V supply with dedicated power/ground pairs per datasheet layout; decoupling required within 10 mm of balls. |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous Static Operation | No clock, no refresh-simplifies timing design and eliminates hidden refresh overhead in real-time deterministic systems. |
| Byte-Selectable Write | BHE/ BLE pins permit isolated 8-bit writes, reducing bus traffic and avoiding destructive reads in firmware update or configuration storage. |
| LVTTL Compatibility | Direct interface to 3.3 V microcontrollers, FPGAs, and ASICs without level shifters-reducing BOM count and signal integrity risk. |
| Industrial Temperature Support | Guaranteed 15 ns performance over –40°C to +85°C-qualified for deployment in uncontrolled ambient environments like telecom cabinets. |
| Low-Power Standby Mode | ISB1 = 10 mA (static), enabling <10 mW standby power-suitable for always-on edge nodes with intermittent activity patterns. |

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-45ZSXI | 1 Mbit (64K × 16), 45 ns access, 3.3 V, SOIC-44 package; higher tAA limits bandwidth in >22 MHz systems. | Targeted at cost-sensitive industrial controls where speed margin is relaxed; lacks FBGA option. | Select when board space permits SOIC and 45 ns latency is acceptable-avoid for high-throughput buffering. |
| AS6C1008-55TIN | 1 Mbit (128K × 8), 55 ns access, 3.3 V, TSOP-32; narrower 8-bit bus requires two devices for 16-bit width. | Suitable for legacy 8-bit microcontroller interfaces; doubles component count and routing complexity for 16-bit use cases. | Choose only if existing design uses 8-bit data paths or requires TSOP for rework compatibility. |
Compared with CY62167EV30LL-45ZSXI and AS6C1008-55TIN, the 71V016SA15BFG delivers 2.7× faster access, native 16-bit bus support, and space-saving FBGA packaging-making it optimal for new designs prioritizing latency, density, and thermal performance.

FAQ
What is the maximum operating frequency supported by the 71V016SA15BFG?
The 71V016SA15BFG does not operate on a clock but supports asynchronous bus frequencies up to approximately 66 MHz, derived from its 15 ns access time (tAA) and 15 ns cycle time (tRC). System-level timing must account for board trace delays and controller setup/hold margins-actual achievable bandwidth depends on host interface capability and bus width utilization.
Does the 71V016SA15BFG require external refresh circuitry?
No, the 71V016SA15BFG is a fully static RAM and requires no refresh cycles or external refresh circuitry. Its CMOS latching cells retain data indefinitely as long as VDD is maintained within specification (3.15–3.6 V) and temperature remains within –40°C to +85°C. This eliminates timing-critical refresh overhead in real-time systems.
Can the 71V016SA15BFG be used with a 5 V microcontroller interface?
No-the 71V016SA15BFG is strictly a 3.3 V LVTTL device with VIH minimum of 2.0 V and absolute maximum input voltage of VDD + 0.5 V (≤4.1 V). Direct connection to 5 V logic violates absolute maximum ratings and risks permanent damage. Level-shifting circuitry is mandatory for interoperability with 5 V systems.
What is the meaning of "BFG" in the part number 71V016SA15BFG?
In the 71V016SA15BFG ordering code, "BFG" denotes the 48-ball plastic FBGA package variant (BFG48) with green (lead-free) construction. It distinguishes this version from SOJ (YG), TSOP (PHG), or non-green FBGA (BF) variants-ensuring correct mechanical and thermal footprint selection during PCB layout.
Is the 71V016SA15BFG pin-compatible with other speed grades in the same package?
Yes-71V016SA10BFG, 71V016SA12BFG, 71V016SA15BFG, and 71V016SA20BFG share identical BFG48 pinout, electrical interface, and functional behavior. Only access and cycle timing parameters differ; they are drop-in replacements for timing-margin adjustments without PCB or firmware changes.
