Product details
Overview
71V416L10PHG from Renesas Electronics is a 4-Mbit (256K × 16) high-speed CMOS static RAM with 10 ns access time, single 3.3 V supply operation, LVTTL-compatible I/O, and JEDEC-standard center-power/ground pinout. It supports byte-wide and word-wide read/write operations via independent BHE/BLE controls and is used in embedded controllers, network interface buffers, and industrial PLC memory expansion.
For engineers reviewing the 71V416L10PHG datasheet, 71V416L10PHG pinout, 71V416L10PHG application, or 71V416L10PHG equivalent, key selection criteria include its 10 ns read cycle time, low-power standby current (10 mA), TSOP Type II package compatibility, and industrial temperature range support (–40°C to +85°C).
Technical Context
The 71V416L10PHG implements fully static asynchronous circuitry-no clocks or refresh required-and uses dual-byte enable (BHE/BLE) for selective 8-bit access within the 16-bit data bus. Its address decoding supports 18-bit addressing (A0–A17) for full 256K-word coverage.
Operation relies on three independent control signals: Chip Select (CS), Output Enable (OE), and Write Enable (WE), enabling precise timing control across read, write, and standby modes. All inputs and outputs 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 |

| Access Time (tAA) | 10 ns - determines minimum latency between address assertion and valid data output |
| Supply Voltage | 3.0–3.6 V - compatible with standard 3.3 V logic rails without level-shifting |
| Standby Current (ISB1) | 10 mA - enables low-power hold mode during system sleep states |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded systems |

Pinout & Package
71V416L10PHG is packaged in a 44-pin, 400-mil TSOP Type II (PHG44) with JEDEC-standard center-power/ground layout to minimize switching noise. Pin 1 is located at the top-left corner of the top view, with pins numbered counter-clockwise.

|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word addressing; no internal latching |
| CS | Chip Select | Active-low global enable; device enters high-impedance state when deasserted |
| OE | Output Enable | Active-low control for output drivers; allows shared bus operation with other devices |
| WE | Write Enable | Active-low signal initiating write cycles; combined with CS and BHE/BLE defines write type |
| BHE / BLE | Byte Enable | Independent active-low controls for upper (I/O8–I/O15) and lower (I/O0–I/O7) data bytes |
| I/O0–I/O15 | Bidirectional Data | 16-bit LVTTL-compliant I/O bus; direction controlled by WE, CS, and OE states |
| VDD | Power Supply | +3.3 V core and I/O supply; two dedicated pins (pins 12 & 33) reduce IR drop |
| VSS | Ground | Reference ground; two dedicated pins (pins 11 & 34) improve noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Center Power/Ground Pinout | Reduces simultaneous switching noise (SSN) by symmetrically distributing VDD/VSS pins around the perimeter |

FAQ
What is the maximum clock frequency supported by the 71V416L10PHG?
The 71V416L10PHG is a fully static asynchronous SRAM and does not use a clock signal. Its performance is defined by timing parameters such as tRC (10 ns read cycle time) and tAA (10 ns address access time), enabling reliable operation in systems with bus frequencies up to approximately 100 MHz under ideal timing margins. System-level timing must account for board trace delays and controller setup/hold requirements.
Does the 71V416L10PHG require refresh circuitry?
No, the 71V416L10PHG is a static RAM and contains no capacitive storage cells. It retains data indefinitely as long as power is applied and does not require periodic refresh cycles-unlike DRAM. This eliminates refresh-related timing complexity and power spikes, making it ideal for deterministic real-time systems.
Can the 71V416L10PHG be used with 5 V logic interfaces?
No, the 71V416L10PHG operates exclusively at 3.3 V and is LVTTL-compatible, not TTL-compatible. Its input voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and absolute maximum ratings (VDD ≤ +4.6 V) do not support direct connection to 5 V buses. Level-shifting circuitry is required for interoperability with 5 V controllers or peripherals.
What is the function of the BHE and BLE pins on the 71V416L10PHG?
The BHE (Bus High Enable) and BLE (Bus Low Enable) pins on the 71V416L10PHG are active-low signals that independently control access to the upper (I/O8–I/O15) and lower (I/O0–I/O7) bytes of the 16-bit data bus. When asserted, they allow byte-selective reads or writes without affecting the opposite byte-enabling efficient 8-bit peripheral interfacing and reducing unnecessary bus activity.
Is the 71V416L10PHG RoHS-compliant and lead-free?
Yes, the 71V416L10PHG is a green part and complies with RoHS Directive 2011/65/EU. The "G" suffix in the part number (PHG) explicitly denotes Pb-free, halogen-free packaging. Renesas confirms this in the Ordering Information section of the datasheet, and all PHG44-packaged units shipped post-2021 meet current environmental compliance standards.
