Product details
Overview
71V016SA15BFGI from Renesas Electronics is a 64K × 16-bit, 1 Mbit high-speed CMOS static RAM with 15 ns read/write cycle time, single 3.3 V supply operation, industrial temperature range (–40°C to +85°C), and 48-ball FBGA (BFG48) package. It serves as a non-refresh, asynchronous memory buffer in real-time control systems requiring deterministic access latency.
For engineers reviewing the 71V016SA15BFGI datasheet, 71V016SA15BFGI pinout, 71V016SA15BFGI application, or 71V016SA15BFGI equivalent, key selection criteria include byte-enable-controlled 16-bit word access, LVTTL-compatible bidirectional I/Os, low-impedance output timing (tOLZ = 0 ns), and industrial-grade standby current (ISB = 35 mA).
Technical Context
The 71V016SA15BFGI implements fully static asynchronous circuitry-no clocks or refresh required-and uses dual byte enable (BHE/ BLE) to support independent 8-bit accesses within the 16-bit data bus. Its address decoding is combinatorial, with tAA = 15 ns and tACS = 15 ns guaranteeing consistent access under CS- or OE-controlled read cycles.
Operation relies on three independent control paths: chip select (CS) for device activation, output enable (OE) for tri-state control of I/Os, and write enable (WE) combined with BHE/ BLE to gate write data per byte lane. All inputs meet LVTTL voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) at 3.3 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576 bits), enabling direct 16-bit microprocessor or DSP interface without data splitting |
| Access/Cycle Time | 15 ns - guarantees worst-case read/write completion within fixed latency for hard real-time timing budgets |
| Supply Voltage | 3.15–3.6 V - compatible with standard 3.3 V logic rails and tolerant of ±4.5% regulation variation |
| Operating Temperature | –40°C to +85°C - qualified for industrial control, motor drives, and outdoor embedded systems |
| Standby Current | ISB = 35 mA max - enables low-power hold mode during processor sleep without data loss |
| I/O Interface | LVTTL-compatible bidirectional I/Os - interoperable with 3.3 V FPGA I/O banks and microcontroller GPIOs |
| Package | 48-ball FBGA (BFG48), 7 mm × 7 mm - supports high-density PCB layouts with fine-pitch routing |
Pinout & Package
48-ball plastic FBGA (BFG48) package, 7 mm × 7 mm body, 0.8 mm ball pitch, JEDEC MO-244AC compliant. Ball grid arranged in 7×7 array with corner balls omitted (A1, A7, G1, G7 not populated).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus accepting full 64K-word range; no internal latching - requires stable address during CS low |
| CS | Chip Select | Active-low enable: device responds only when CS = L; enables multi-chip memory expansion with decode logic |
| WE | Write Enable | Active-low write strobe; sampled synchronously with CS/BHE/ BLE to initiate byte-aligned write cycles |
| OE | Output Enable | Active-low control for I/O bus drivers; allows shared data bus usage with other peripherals without external transceivers |
| BHE, BLE | Byte Enable | Independent high/low byte gating: enables 8-bit writes to upper (I/O8–I/O15) or lower (I/O0–I/O7) byte lanes |
| I/O0–I/O15 | Bidirectional Data | True bidirectional LVTTL I/Os - automatically switch direction based on WE and OE states; no external direction control needed |
| VDD | Power Supply | 3.3 V core and I/O supply; two dedicated VDD balls (D1, E1) reduce switching noise coupling |
| VSS | Ground | Ground reference; four VSS balls (D7, E7, F1, F7) provide low-inductance return paths for I/O and core currents |
Key Features
| Feature | Design Value |
|---|---|
| Zero Power Standby | ISB1 = 10 µA typical - maintains data integrity with negligible current draw during extended idle periods |
| Fast Output Enable | tOE = 7 ns max - minimizes bus turnaround delay in multiplexed memory/data bus architectures |
| Byte-Selectable Writes | BHE/ BLE support independent 8-bit writes - eliminates need for read-modify-write sequences in partial-word updates |
| No Clock or Refresh Required | Fully static design - removes timing constraints from system clock domain and eliminates refresh overhead in firmware |
| Industrial Temperature Support | Rated –40°C to +85°C across full speed grade - validated for use in uncontrolled ambient environments without derating |

FAQ
What is the maximum operating frequency supported by the 71V016SA15BFGI?
The 71V016SA15BFGI does not operate on a clock signal-it is an asynchronous SRAM. Its performance is defined by timing parameters: maximum read/write cycle time is 15 ns, corresponding to an effective bandwidth of approximately 66.7 MHz when continuously cycling. System-level throughput depends on address setup/hold and control signal timing margins.
Does the 71V016SA15BFGI require external refresh circuitry?
No, the 71V016SA15BFGI is a fully static RAM and requires no refresh cycles or external refresh circuitry. Data retention is maintained indefinitely as long as VDD remains within specification (3.15–3.6 V) and ambient temperature stays within –40°C to +85°C. This eliminates firmware overhead and timing uncertainty associated with DRAM refresh.
Can the 71V016SA15BFGI be used with a 5 V microcontroller interface?
No-the 71V016SA15BFGI is strictly a 3.3 V LVTTL device. Its input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and output drive levels (VOH ≥ 2.4 V, VOL ≤ 0.4 V at 3.3 V) are incompatible with 5 V TTL logic. Direct connection to 5 V systems risks damage or unreliable operation; level-shifting circuitry is mandatory.
What is the function of the BHE and BLE pins on the 71V016SA15BFGI?
BHE (High Byte Enable) and BLE (Low Byte Enable) are active-low control inputs that independently gate the upper (I/O8–I/O15) and lower (I/O0–I/O7) byte lanes during write operations. When only one is asserted, the 71V016SA15BFGI performs an 8-bit write without affecting the other byte-enabling efficient partial-word updates without read-modify-write sequences.
Is the 71V016SA15BFGI pin-compatible with other speed grades in the same package?
Yes-all 71V016SA variants (10/12/15/20 ns) in the BFG48 package share identical pinout, ball map, and DC/AC electrical interface. The 71V016SA15BFGI can be substituted with 71V016SA12BFGI or 71V016SA10BFGI on the same PCB, provided timing margins and power delivery support the faster grade's higher ICC.
