Product details
Overview
IDT71V416L10BEGI8 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 industrial temperature range (–40°C to +85°C). It features separate byte enable (BHE/BLE), output enable (OE), and chip select (CS) for flexible memory interfacing in embedded controllers and real-time data buffering systems.
For engineers reviewing the IDT71V416L10BEGI8 datasheet, IDT71V416L10BEGI8 pinout, IDT71V416L10BEGI8 application, or IDT71V416L10BEGI8 equivalent, key selection considerations include its 10 ns read cycle time, 44-pin TSOP Type II package with JEDEC center power/GND pinout, low-power standby current (10 mA max), and support for word/byte-level read/write operations without refresh or clocks.
Technical Context
The IDT71V416L10BEGI8 implements fully static asynchronous circuitry-no clocks or refresh required-and uses high-reliability CMOS technology optimized for deterministic timing. Its dual-byte enable architecture allows independent access to upper and lower 8-bit data lanes, while the OE pin enables fast 5 ns output enable timing independent of CS transitions.
Address decoding is handled by internal row/column decoders driving a 4,194,304-bit memory array. All control inputs (CS, WE, OE, BHE, BLE) and bidirectional I/Os are LVTTL-compatible, ensuring seamless integration with 3.3 V logic families. The device supports three distinct write control modes: WE-controlled, CS-controlled, and byte-enable-controlled timing.

FAQ
What is the operating voltage range for the IDT71V416L10BEGI8?
The IDT71V416L10BEGI8 operates over a supply voltage range of 3.0 V to 3.6 V. This 3.3 V nominal specification ensures compatibility with standard LVTTL logic families and accommodates typical power rail tolerances in industrial systems. Operation outside this range may result in undefined behavior or permanent damage, as specified in the absolute maximum ratings table.
Does the IDT71V416L10BEGI8 require a clock or refresh circuit?
No, the IDT71V416L10BEGI8 uses fully static asynchronous circuitry and requires neither a clock nor periodic refresh. This eliminates timing dependencies on external clocks and removes the need for refresh controllers or associated firmware overhead-making it ideal for safety-critical and low-power embedded applications where deterministic latency is essential.
What package type is used for the IDT71V416L10BEGI8?
The IDT71V416L10BEGI8 is packaged in a 44-pin, 400-mil TSOP Type II (PHG44) with industrial temperature grading. This surface-mount package adheres to JEDEC standards, features center-placed VDD/VSS pins for noise reduction, and is compatible with standard reflow soldering processes and IPC-7351B footprint guidelines.
How does the byte enable functionality work on the IDT71V416L10BEGI8?
The IDT71V416L10BEGI8 provides two independent byte enable inputs: BHE (high byte enable) for I/O8–I/O15 and BLE (low byte enable) for I/O0–I/O7. When either is asserted low (with CS and WE active), only the corresponding 8-bit lane is written; both must be low for full 16-bit word writes. This enables efficient partial-word updates without external masking logic.
What is the maximum standby current for the IDT71V416L10BEGI8 at industrial temperature?
The maximum full standby current (ISB1) for the IDT71V416L10BEGI8 at industrial temperature (–40°C to +85°C) is 10 mA. This static current draw occurs when CS is high and no address or control lines are toggling-critical for estimating worst-case power consumption during system sleep modes in battery-backed or energy-constrained applications.
