Product details
Overview
71V416S10PHGI8 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, and industrial temperature range (–40°C to +85°C). It features LVTTL-compatible bidirectional I/O, separate byte enable (BHE/BLE), and JEDEC-standard center power/ground pinout for noise reduction. Used in real-time embedded controllers requiring deterministic low-latency memory access.
For engineers reviewing the 71V416S10PHGI8 datasheet, 71V416S10PHGI8 pinout, 71V416S10PHGI8 application, or 71V416S10PHGI8 equivalent, key selection criteria include 10 ns read cycle time, TSOP-II package compatibility, industrial-grade reliability, byte-selectable write capability, and 3.3 V LVTTL interface compliance.
Technical Context
The 71V416S10PHGI8 implements fully static asynchronous architecture-no clocks or refresh required-and uses high-reliability CMOS process technology. Its dual-byte enable (BHE/BLE) supports independent 8-bit writes, while OE-controlled output timing achieves 5 ns output enable delay.
Address decoding is internal and fully decoded across A0–A17 (18 address lines); all control inputs (CS, WE, OE, BHE, BLE) are active-low and LVTTL-compatible. The device operates with zero address setup/hold requirements (tAS = tWR = 0 ns) and guarantees tAA = tACS = 10 ns under industrial conditions.

FAQ
What is the operating voltage range for the 71V416S10PHGI8?
The 71V416S10PHGI8 operates over a supply voltage range of 3.0 V to 3.6 V, making it compatible with standard 3.3 V LVTTL logic families. This range is specified across the full industrial temperature range (–40°C to +85°C) and supports stable operation without external regulation beyond standard decoupling.
Does the 71V416S10PHGI8 require a clock or refresh signal?
No, the 71V416S10PHGI8 is a fully static RAM and requires neither a clock nor periodic refresh. Its asynchronous design allows immediate read/write access upon valid address and control signals, eliminating timing constraints associated with dynamic memory and simplifying system-level timing budgets.
What package type is used for the 71V416S10PHGI8?
The 71V416S10PHGI8 uses a 44-pin, 400-mil TSOP Type II package (PHG44), with JEDEC-standard pinout featuring center-placed VDD and VSS pins to minimize noise coupling. This surface-mount package supports automated assembly and meets industrial thermal cycling requirements.
How does byte enable functionality work on the 71V416S10PHGI8?
The 71V416S10PHGI8 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 only one is asserted low with WE low, only the corresponding 8-bit lane is written; both must be low for full 16-bit writes. This enables efficient partial-word updates without external masking logic.
Is the 71V416S10PHGI8 RoHS compliant and halogen-free?
Yes, the 71V416S10PHGI8 is a green-part variant (indicated by the 'G' in the part number suffix) and complies with RoHS Directive 2011/65/EU and JEDEC JS709 standards for halogen-free materials. Full compliance documentation, including substance declarations and test reports, is available through Renesas' quality portal.
