Product details
Overview
IDT71V416VL15BEGI from Integrated Device Technology is a 256K × 16-bit (4 Mbit), 3.3V CMOS static RAM with 15 ns access time, JEDEC-compliant center power/ground pinout, and LVTTL-compatible bidirectional I/O. It supports byte-wide and word-wide read/write operations via independent BHE/BLE controls and operates across –40°C to +85°C for industrial embedded systems requiring deterministic asynchronous memory access.
For engineers reviewing the IDT71V416VL15BEGI datasheet, IDT71V416VL15BEGI pinout, IDT71V416VL15BEGI application, or IDT71V416VL15BEGI equivalent, key selection criteria include industrial temperature support, 15 ns cycle time, SOJ/TSOP/BGA package compatibility, byte-enable granularity, and low-power standby current of 10 mA max in full standby mode.
Technical Context
The IDT71V416VL15BEGI implements fully static asynchronous circuitry-no clocks or refresh required-and uses high-reliability CMOS fabrication optimized for stable operation under industrial thermal stress. Its dual-byte enable architecture (BHE/BLE) enables selective 8-bit writes without disturbing adjacent data, while OE-controlled output timing achieves 5 ns output enable delay.
Pinout follows JEDEC standard for noise reduction: VDD and VSS are centrally located on opposite sides of the 44-pin SOJ/TSOP package. The device supports three distinct write control modes-CS-, WE-, or byte-enable–triggered-with timing parameters fully characterized for all combinations across industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 256K × 16-bit (4,194,304-bit total); supports 16-bit parallel data bus interface |
| Access Time (tAA) | 15 ns max at VDD = 3.0–3.6 V, –40°C to +85°C; defines minimum address-to-data-valid latency |
| Read Cycle Time (tRC) | 15 ns max; determines maximum sustained random read throughput (66.7 MHz) |
| Standby Current (ISB1) | 10 mA max at VDD = 3.6 V, T = –40°C to +85°C; enables low-power idle states in battery-backed or energy-sensitive systems |

| Operating Temperature | –40°C to +85°C industrial grade; validated for use in motor drives, PLCs, and telecom line cards without derating |
| Package Type | 44-pin, 400-mil plastic SOJ (SO44-1) - leaded, surface-mount, JEDEC-standard footprint |
Pinout & Package
Package: 44-pin, 400-mil plastic SOJ (SO44-1), JEDEC-standard leaded surface-mount package with center VDD/VSS pin arrangement for reduced switching noise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word addressing; no internal latching |
| CS | Chip Select | Active-low enable for device selection; must be stable before address setup (tAS = 0 ns) |

| WE | Write Enable | Active-low write strobe; initiates write cycles when CS and BHE/BLE are active |
| BHE / BLE | Byte Enable (High/Low) | Independent 8-bit write masking: BHE controls I/O8–I/O15, BLE controls I/O0–I/O7 |
| I/O0–I/O15 | Bidirectional Data Bus | LVTTL-compatible 16-bit I/O; high-impedance when CS high or OE high |
| VDD | Power Supply | 3.3 V ±10% supply; center-pin placement minimizes simultaneous switching noise |

| 15 ns Industrial-Grade Timing | Guaranteed tAA/tRC ≤15 ns over –40°C to +85°C, enabling real-time deterministic memory access in motion control |
| Low Full-Standby Current (ISB1) | 10 mA max at VDD = 3.6 V and full temperature range-supports extended sleep modes in industrial gateways |
| Fully Static Asynchronous Operation | No clock, no refresh, no wait states-simplifies integration with legacy microcontrollers and FPGA soft cores |
Applications
| Industrial PLC Memory Buffer | DSP Data Scratchpad |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-15ZXI | Same 256K×16 organization, 15 ns speed, but uses TSOP II only (no SOJ); higher ISB1 (25 mA) | Requires PCB redesign if migrating from SOJ; better suited for space-constrained board layouts | Select when TSOP II footprint is preferred and higher standby current is acceptable |
| AS6C4008-15PIN | 256K×16, 15 ns, SOJ-44 compatible, but commercial temp only (0°C to +70°C); lower ICC (160 mA vs 170 mA) | Not qualified for industrial environments; unsuitable for outdoor or factory-floor deployments | Select only for cost-sensitive commercial equipment with controlled ambient conditions |
Compared with CY62167EV30LL-15ZXI and AS6C4008-15PIN, the IDT71V416VL15BEGI uniquely combines SOJ-44 industrial qualification, JEDEC noise-optimized pinout, and 10 mA full-standby current-making it the only option for legacy SOJ-based industrial controllers requiring long-term availability and thermal robustness.

FAQ
What is the guaranteed operating temperature range for the IDT71V416VL15BEGI?
The IDT71V416VL15BEGI is rated for industrial temperature operation from –40°C to +85°C. This specification is fully guaranteed per AC and DC electrical characteristics tables in the official datasheet, including 15 ns access time, 10 mA ISB1 standby current, and LVTTL I/O thresholds across the full range. No derating is required within these limits.
Does the IDT71V416VL15BEGI support byte-wide write operations?
Yes, the IDT71V416VL15BEGI supports true byte-wide writes via dedicated BHE (high-byte enable) and BLE (low-byte enable) inputs. 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 signals can be asserted simultaneously for full 16-bit word writes.
What package type does the IDT71V416VL15BEGI use, and is it leaded or lead-free?
The IDT71V416VL15BEGI uses a 44-pin, 400-mil plastic SOJ (SO44-1) package with gull-wing leads. Per ordering information in the datasheet, the "G" suffix denotes RoHS-compliant, lead-free finish. The part is fully compatible with standard SOJ reflow profiles and manual soldering processes.
Can the IDT71V416VL15BEGI operate with a 3.0 V supply voltage?
Yes, the IDT71V416VL15BEGI is specified to operate across VDD = 3.0 V to 3.6 V. All AC and DC parameters-including 15 ns access time, 10 mA ISB1, and LVTTL-compatible VIH/VOH-are guaranteed at VDD = 3.0 V and –40°C to +85°C. System designers may use 3.0 V to reduce dynamic power without sacrificing timing compliance.
Is the IDT71V416VL15BEGI pin-compatible with earlier IDT71V416 speed grades?
Yes, the IDT71V416VL15BEGI is pin-compatible with other IDT71V416 variants in the same SOJ-44 package (e.g., IDT71V416VL12BEGI, IDT71V416VL10BEGI). All share identical pinout, signal definitions, power requirements, and timing architecture-only access/cycle times differ. No PCB changes are needed when upgrading from slower grades.
