Product details
Overview
71V016SA15BFGI8 from Renesas Electronics is a 64K × 16-bit, 1 Mbit high-speed CMOS static RAM with 15 ns read 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-refreshing, asynchronous memory buffer in embedded controllers, network interface cards, and real-time data acquisition systems.
For engineers reviewing the 71V016SA15BFGI8 datasheet, 71V016SA15BFGI8 pinout, 71V016SA15BFGI8 application, or 71V016SA15BFGI8 equivalent, key selection criteria include tRC = 15 ns, tAA = 15 ns, byte-enable support (BHE/BLE), LVTTL-compatible I/O, and industrial-grade reliability in compact FBGA packaging.
Technical Context
The 71V016SA15BFGI8 implements fully static asynchronous circuitry-no clocks or refresh required-and uses high-reliability CMOS technology optimized for low-latency random access. Its dual-byte enable architecture (BHE/BLE) enables independent 8-bit word access within the 16-bit data bus.
Operation is controlled via three active-low control signals: Chip Select (CS), Output Enable (OE), and Write Enable (WE), with timing validated under industrial conditions (–40°C to +85°C) and VDD = 3.15–3.6 V. All I/Os are bidirectional and LVTTL-compatible, supporting direct interfacing with 3.3 V logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576 bits), enabling 65,536 addressable 16-bit words |
| Access Time (tAA) | 15 ns max - guarantees data valid within 15 ns of stable address and CS/OE assertion |
| Read Cycle Time (tRC) | 15 ns max - defines minimum interval between successive read operations |
| Supply Voltage | 3.15–3.6 V - compatible with standard 3.3 V power rails and tolerant of ±4.5% variation |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments without derating |
| I/O Interface | LVTTL-compatible bidirectional I/Os - eliminates level-shifting requirements with 3.3 V microcontrollers and FPGAs |
| Power Consumption | ISB = 35 mA max standby current - supports low-power hold modes during system sleep states |
Pinout & Package
71V016SA15BFGI8 is housed in a 48-ball plastic FBGA (BFG48) package, 7 mm × 7 mm, 0.8 mm ball pitch, JEDEC MO-276 compliant. The package supports automated PCB assembly and offers improved thermal performance over SOJ/TSOP alternatives.

| I/O8–I/O15 | High-Byte Data I/O | Bidirectional 8-bit port enabled by BHE; used for upper byte reads/writes |
| CS | Chip Select | Active-low global enable; device enters standby (high-Z I/O) when deasserted |
| OE | Output Enable | Active-low control for output drivers; allows read data to appear on I/O pins |
| WE | Write Enable | Active-low signal initiating write cycles; latches data on rising edge of WE |
| BLE | Low-Byte Enable | Active-low control enabling I/O0–I/O7 during byte-write or byte-read operations |
| BHE | High-Byte Enable | Active-low control enabling I/O8–I/O15 during byte-write or byte-read operations |
| VDD | Power Supply | 3.3 V core and I/O supply; requires local decoupling per datasheet layout guidelines |
| VSS | Ground | Reference ground for all digital and I/O circuits; multiple balls ensure low-impedance return path |

FAQ
What is the maximum clock frequency supported by the 71V016SA15BFGI8?
The 71V016SA15BFGI8 is an asynchronous static RAM and does not use a clock signal. Its performance is defined by timing parameters such as tRC = 15 ns, which corresponds to a maximum effective cycle rate of 66.7 MHz. System timing must satisfy all AC specifications-including tAA, tOE, and tWP-under worst-case voltage and temperature conditions.
Does the 71V016SA15BFGI8 require external refresh circuitry?
No, the 71V016SA15BFGI8 is a fully static RAM and requires no refresh cycles or external refresh control. Its CMOS latch-based memory cells retain data indefinitely as long as VDD is applied and within specification (3.15–3.6 V), making it ideal for low-jitter, deterministic applications like real-time control and packet buffering.
Can the 71V016SA15BFGI8 operate with 2.5 V or 5 V supplies?
No, the 71V016SA15BFGI8 is specified exclusively for 3.3 V operation (VDD = 3.15–3.6 V). Applying 2.5 V will cause functional failure due to insufficient noise margin and drive strength; applying 5 V exceeds absolute maximum ratings and risks permanent damage. A dedicated 3.3 V regulator is required.
How does byte enable (BHE/BLE) function during a write operation on the 71V016SA15BFGI8?
During a write, asserting BLE (low) enables I/O0–I/O7 for low-byte data transfer while holding I/O8–I/O15 in high-impedance; asserting BHE (low) enables I/O8–I/O15 for high-byte transfer. Both may be asserted simultaneously for full 16-bit writes. This avoids read-modify-write sequences and preserves data integrity in mixed-width bus systems.
Is the 71V016SA15BFGI8 RoHS and REACH compliant?
Yes, the 71V016SA15BFGI8 is a green (lead-free, halogen-free) device compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The "G" and "I" suffixes in the part number denote green material set and industrial temperature grade, respectively, both confirmed in Renesas' official ordering information.
