Product details
Overview
IDT71V416VL10PH from Integrated Device Technology is a 4-Mbit (256K × 16) high-speed CMOS static RAM with 10 ns access time, single 3.3 V supply operation, and LVTTL-compatible bidirectional I/O. It features separate byte enable (BHE/BLE), output enable (OE), and chip select (CS) for flexible memory interfacing in embedded controllers and industrial data acquisition systems.
For engineers reviewing the IDT71V416VL10PH datasheet, IDT71V416VL10PH pinout, IDT71V416VL10PH application, or IDT71V416VL10PH equivalent, key selection criteria include its 10 ns read cycle time, SOJ-44 package with JEDEC-compliant power/ground pinout, low-power standby current (10 mA max), and industrial temperature range (–40°C to +85°C).
Technical Context
The IDT71V416VL10PH implements fully static asynchronous circuitry-no clocks or refresh required-and uses IDT's high-reliability CMOS process. Its address decoding supports A0–A17 (18-bit addressing), enabling direct mapping into 32-bit microprocessor data buses with byte-level granularity via BHE/BLE control.
Timing is governed by three independent control paths: CS-driven, OE-driven, and byte-enable-driven read/write cycles. The device guarantees tAA = 10 ns, tCLZ = 4 ns, and tOE = 5 ns under industrial conditions, with all I/O pins meeting LVTTL voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) at 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4,194,304 bits (256K × 16), supporting 16-bit parallel data bus interfaces without external multiplexing. |
| Access Time (tAA) | 10 ns maximum - enables direct interface with 80 MHz bus systems requiring sub-100 ns total read latency. |
| Supply Voltage | 3.0 V to 3.6 V - compatible with standard 3.3 V logic rails and tolerant of typical PCB voltage droop. |
| Standby Current (ISB1) | 10 mA maximum - ensures low power consumption during processor idle states in battery-backed or energy-sensitive systems. |
| Operating Temperature | –40°C to +85°C - qualified for industrial automation, motor control, and transportation electronics environments. |
| I/O Interface | LVTTL-compatible inputs/outputs - eliminates need for level-shifting when interfacing with FPGA I/O banks or microcontroller GPIOs rated for 3.3 V. |
| Package | 44-pin, 400-mil plastic SOJ (SO44-1) - surface-mountable with JEDEC-standard pinout reducing simultaneous switching noise (SSN). |
Pinout & Package
44-pin, 400-mil plastic SOJ (SO44-1) package with JEDEC center power/ground pinout for reduced noise coupling. Pin 28 is NC or optionally connected to VSS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus accepting full 256K-word space; no internal address latching required. |

| I/O0–I/O15 | Bidirectional Data | 16-bit LVTTL I/O bus with internal direction control; no external transceivers needed for 16-bit microprocessor interfaces. |
| VDD / VSS | Power / Ground | Dual VDD/VSS pairs (pins 12/13 and 33/34) placed centrally per JEDEC spec to minimize IR drop and ground bounce. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-10ZSXI | 4-Mbit (256K × 16), 10 ns, 3.3 V, SOJ-44 - identical speed and voltage but Cypress uses different byte enable polarity (active-high vs. IDT's active-low). | Requires inverting logic on BHE/BLE lines or firmware adaptation for byte write control. | Select only if existing board layout already accommodates active-high byte enables or logic inversion is feasible. |
| AS6C4008-10BIN | 4-Mbit (256K × 16), 10 ns, 3.3 V, SOJ-44 - same timing and package, but lacks dedicated OE pin (output enable integrated into CS function). | Cannot support shared data bus arbitration without external gating; limits multi-peripheral bus designs. | Prefer for simple point-to-point interfaces where OE functionality is unnecessary and cost is primary driver. |
Compared with CY62167EV30LL-10ZSXI and AS6C4008-10BIN, the IDT71V416VL10PH provides explicit OE control and active-low byte enables - critical for deterministic bus sharing and legacy microprocessor compatibility in industrial control systems.

FAQ
What is the operating temperature range for the IDT71V416VL10PH?
The IDT71V416VL10PH is rated for industrial operation from –40°C to +85°C. This specification is validated per the manufacturer's recommended DC operating conditions and AC timing parameters across the full range, making it suitable for deployment in factory automation, transportation, and outdoor infrastructure applications where ambient temperatures exceed commercial limits.
Does the IDT71V416VL10PH require a refresh circuit?
No, the IDT71V416VL10PH is a fully static RAM and requires no refresh cycles. Its asynchronous architecture uses only address, control, and data signals - eliminating clock dependencies and refresh timing constraints. This simplifies system design and guarantees deterministic access latency, a key advantage over DRAM in real-time control applications.
What package type does the IDT71V416VL10PH use?
The IDT71V416VL10PH uses a 44-pin, 400-mil plastic SOJ (SO44-1) package with JEDEC-standard center power/ground pinout. Pin 28 is designated NC but may be tied to VSS for improved grounding. This package supports reflow soldering and is compatible with standard SOJ footprint layouts.
How does the byte enable functionality work on the IDT71V416VL10PH?
The IDT71V416VL10PH features two independent byte enable inputs: BHE (high byte enable) and BLE (low byte enable), both active-low. When BHE is low and BLE is high, only I/O8–I/O15 are written; when BLE is low and BHE is high, only I/O0–I/O7 are written. Both low enables full 16-bit word access - enabling precise byte-level memory updates without read-modify-write sequences.
What is the maximum dynamic operating current for the IDT71V416VL10PH?
The maximum dynamic operating current (ICC) for the IDT71V416VL10PH is 200 mA under industrial conditions (–40°C to +85°C) at VDD = 3.6 V and maximum frequency operation. This value reflects worst-case current draw during continuous read/write cycling and informs power supply sizing and thermal design for dense memory subsystems.
