Product details
Overview
71V016SA15BFG8 from Renesas Electronics is a 64K × 16-bit (1 Mbit), 3.3 V CMOS static RAM with 15 ns read/write cycle time, industrial temperature range (–40°C to +85°C), and FBGA-48 (BFG48) package. It features LVTTL-compatible bidirectional I/O, separate high/low byte enables (BHE/BLE), and single-chip-select plus output-enable control - used in real-time embedded controllers requiring deterministic memory access without refresh.
For engineers reviewing the 71V016SA15BFG8 datasheet, 71V016SA15BFG8 pinout, 71V016SA15BFG8 application, or 71V016SA15BFG8 equivalent, key selection criteria include tRC = 15 ns, tAA = 15 ns, VDD = 3.15–3.6 V, industrial-grade reliability, and FBGA-48 footprint compatibility with space-constrained industrial PLCs and telecom line cards.
Technical Context
This device implements fully static asynchronous circuitry - no clocks or refresh required - with independent byte enable control enabling 8-bit sub-word access. Its dual-byte architecture supports partial writes without disturbing adjacent data, critical for register-mapped peripheral buffers.
Timing is governed by three parallel control paths: chip-select (tACS), output-enable (tOE), and byte-enable (tBE), each with guaranteed 15 ns max access under industrial conditions. All inputs and outputs meet LVTTL voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) at 3.3 V supply.
Key Specifications

| Access Time (tAA) | 15 ns max at VDD = 3.15–3.6 V, TA = –40°C to +85°C; ensures deterministic latency in hard real-time systems |
| 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 logic rails and tolerant of ±4.5% regulation drift |
| I/O Interface | LVTTL-compatible bidirectional data bus (I/O0–I/O15); interfaces directly with FPGA I/O banks and microcontroller data buses |
| Power Consumption | ISB1 = 10 µA typical full standby current; enables ultra-low-power sleep modes in battery-backed systems |

Pinout & Package
71V016SA15BFG8 is housed in a 48-ball plastic FBGA (BFG48) package, 7 mm × 7 mm, 0.8 mm ball pitch, JEDEC MO-244 compliant. Pinout follows standard FBGA top-view layout with corner ball A1 marked.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus; selects one of 64K memory locations; latched on CS/WE transitions |
| I/O0–I/O7 | Low-Byte Data I/O | Bidirectional 8-bit data path enabled only when BLE = L; isolated from high byte during partial writes |
| I/O8–I/O15 | High-Byte Data I/O | Bidirectional 8-bit data path enabled only when BHE = L; operates independently of low byte |
| CS | Chip Select | Active-low global enable; places device in active or high-Z state; controls tACS timing path |
| OE | Output Enable | Active-low output gate; enables data output drivers with tOE ≤ 7 ns; overrides WE during reads |
| WE | Write Enable | Active-low write strobe; initiates write cycles with tWP ≥ 10 ns; determines tAW/tDW timing margins |
| BLE | Low-Byte Enable | Active-low control for I/O0–I/O7; allows 8-bit writes without affecting high byte |
| BHE | High-Byte Enable | Active-low control for I/O8–I/O15; enables independent high-byte access |
| VDD | Power Supply | 3.3 V core and I/O supply; requires local 0.1 µF decoupling per VDD ball |
| VSS | Ground | Reference ground for all signals; multiple VSS balls ensure low-inductance return path |

FAQ
What is the maximum operating frequency supported by the 71V016SA15BFG8?
The 71V016SA15BFG8 is an asynchronous SRAM with no clock input, so it does not have an operating frequency specification. Instead, its performance is defined by timing parameters: tRC = 15 ns minimum cycle time supports up to 66.7 MHz effective throughput in burst-read scenarios, but actual bandwidth depends on system-level address/data bus setup and hold margins. The 71V016SA15BFG8 achieves this with guaranteed tAA = 15 ns across –40°C to +85°C.
Does the 71V016SA15BFG8 require external refresh circuitry?
No, the 71V016SA15BFG8 is a fully static RAM and requires no refresh circuitry or periodic access to retain data. Its internal latches maintain state indefinitely as long as VDD remains within 3.15–3.6 V and ambient temperature stays within –40°C to +85°C. This eliminates refresh overhead in microcontroller or FPGA-based memory controllers - a key advantage of the 71V016SA15BFG8 in real-time systems.
Can the 71V016SA15BFG8 operate with a 3.0 V supply?
No, the 71V016SA15BFG8 is specified only for VDD = 3.15–3.6 V per its DC Electrical Characteristics table. While some earlier IDT SRAM variants supported 3.0 V, the 71V016SA15BFG8's VIH/VIL thresholds and internal timing are validated exclusively across 3.15–3.6 V. Operating below 3.15 V risks timing violations and data corruption - always verify supply compliance before integrating the 71V016SA15BFG8 into your power architecture.
How does byte enable functionality work on the 71V016SA15BFG8?
The 71V016SA15BFG8 uses two dedicated inputs - BHE (high-byte enable) and BLE (low-byte enable) - to control 8-bit sub-word writes independently. When BLE = L and BHE = H, only I/O0–I/O7 are written; when BHE = L and BLE = H, only I/O8–I/O15 are written. Both must be L for full 16-bit writes. This avoids read-modify-write sequences, reducing bus traffic and power - a core capability of the 71V016SA15BFG8 in register-mapped peripherals.
Is the 71V016SA15BFG8 RoHS and REACH compliant?
Yes, the 71V016SA15BFG8 is a green-part designation ('G' in ordering code) and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Renesas confirms lead-free terminations, halogen-free molding compound, and absence of SVHC substances above threshold limits - documentation is available in the official 71V016SA15BFG8 product change notice and material declaration sheets.
