Product details
Overview
IDT71V416VL15PHG from Integrated Device Technology is a 256K × 16-bit (4 Mbit), 3.3V single-supply CMOS static RAM with 15 ns access time, JEDEC-standard center power/ground pinout, and separate high- and low-byte enable for embedded memory interfacing in industrial temperature range (–40°C to +85°C) applications.
For engineers reviewing the IDT71V416VL15PHG datasheet, IDT71V416VL15PHG pinout, IDT71V416VL15PHG application, or IDT71V416VL15PHG equivalent, key selection criteria include byte-selectable 16-bit I/O, LVTTL-compatible bidirectional data lines, 44-pin SOJ package compatibility, and industrial-grade standby current of 10 mA max at full static standby.
Technical Context
The IDT71V416VL15PHG implements fully static asynchronous operation-no clocks or refresh required-and uses dedicated OE, CS, WE, BHE, and BLE control inputs to manage read/write cycles, byte masking, and output enable/disable states independently. Its architecture supports word, high-byte, and low-byte write operations with guaranteed timing margins across industrial temperature.
All I/Os are LVTTL-compatible with VIH = 2.0 V min and VIL = 0.8 V max; DC leakage is limited to ±5 µA per pin. The device features dual VDD/VSS pairs (pins 12 & 33, 13 & 34) and center-grounded layout to minimize switching noise in high-density PCB designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 256K × 16-bit (4,194,304-bit total); enables direct 16-bit bus interface without external data multiplexing |
| Access Time (tAA) | 15 ns max at VDD = 3.0–3.6 V, –40°C to +85°C; determines minimum CPU wait-state insertion for synchronous bus interfaces |
| Supply Voltage | 3.3 V nominal (3.0–3.6 V range); compatible with modern LVTTL and LVCMOS logic families without level translation |
| Standby Current (ISB1) | 10 mA max at VDD = 3.6 V, f = 0; ensures ultra-low power retention during system sleep modes |
| Input Capacitance | 7 pF max (SOJ package); reduces signal integrity risk on high-speed address/data buses |
| Output Drive | VOL ≤ 0.4 V at IOL = 8 mA; guarantees robust low-level noise margin under loaded conditions |
| Byte Enable Setup | tAS = 0 ns; allows simultaneous assertion of address and BLE/BHE without timing penalty |
Pinout & Package
Package: 44-pin, 400-mil plastic SOJ (SO44-1), JEDEC-standard footprint with center VDD/VSS pins for noise reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word addressing; no A18 needed due to 16-bit width |
| I/O0–I/O7 | Low-Byte Data I/O | Bidirectional 8-bit data path enabled only when BLE = L; isolated from high byte during partial writes |
| I/O8–I/O15 | High-Byte Data I/O | Bidirectional 8-bit data path enabled only when BHE = L; supports independent high-byte updates |
| CS | Chip Select | Active-low global enable; device enters high-Z standby when CS = H, reducing system bus contention |
| OE | Output Enable | Active-low control for output drivers; allows read data gating without disabling chip select |
| WE | Write Enable | Active-low write strobe; initiates write cycle only when CS, WE, and BLE/BHE are all asserted |
| BLE | Low-Byte Enable | Active-low mask for I/O0–I/O7; enables byte-selective writes without affecting high byte |
| BHE | High-Byte Enable | Active-low mask for I/O8–I/O15; permits partial writes while preserving other byte contents |
| VDD | Power Supply | 3.3 V supply (pins 12 and 33); dual placement minimizes IR drop and improves PSRR |
| VSS | Ground | Ground reference (pins 13 and 34); center-aligned with VDD for symmetric return path and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Center Power/Ground Pinout | Reduces simultaneous switching noise by 30–40% vs. corner-pin layouts; critical for stable 15 ns timing in dense systems |
| Independent Byte Enables (BHE/ BLE) | Enables true 8-bit sub-word writes in 16-bit systems-eliminates read-modify-write overhead for peripheral register updates |
| LVTTL-Compatible I/O | Direct interface to 3.3 V microcontrollers, FPGAs, and ASICs without level shifters or external termination resistors |
| Zero-Setup Address Timing (tAS = 0 ns) | Allows address and control signals to launch simultaneously from same clock edge-simplifies FPGA timing closure |
| Industrial Temperature Range | Guaranteed operation from –40°C to +85°C; qualified for use in base stations, industrial PLCs, and transportation control units |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed parallel SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-15ZSXI | Same 256K×16 organization, 15 ns speed, but uses TSOP-II package (44-pin) and has higher ISB1 (25 mA) | Higher standby current limits battery life in portable instruments; TSOP-II requires different PCB footprint | Select if board layout already uses TSOP-II and thermal budget allows +15 mA standby increase |
| AS6C4008-15PCN | 256K×16, 15 ns, but rated only for commercial temp (0°C to +70°C); no industrial qualification | Not suitable for deployments outside controlled environments; lacks extended temperature validation | Choose only for cost-sensitive non-industrial applications where ambient stays within 0–70°C |
Compared with CY62167EV30LL-15ZSXI and AS6C4008-15PCN, the IDT71V416VL15PHG uniquely combines industrial temperature rating, 10 mA ISB1, and SOJ package in a single solution-making it optimal for reworkable, thermally demanding, and power-constrained embedded systems.

FAQ
What is the maximum operating temperature range for the IDT71V416VL15PHG?
The IDT71V416VL15PHG is rated for industrial temperature operation from –40°C to +85°C. This specification is guaranteed across all AC and DC parameters in the datasheet, including access time, standby current, and input/output voltage thresholds. The "I" suffix in the ordering code explicitly denotes industrial qualification, and thermal validation was performed per JEDEC JESD22-A104.
Does the IDT71V416VL15PHG require external refresh circuitry?
No, the IDT71V416VL15PHG is a fully static RAM and requires no refresh cycles or clocks. Its internal circuitry maintains data indefinitely as long as VDD remains within 3.0–3.6 V and ambient temperature stays within –40°C to +85°C. This eliminates timing-critical refresh overhead in microcontroller or FPGA-based systems using the IDT71V416VL15PHG.
Can the IDT71V416VL15PHG be used with a 5 V microcontroller interface?
No-the IDT71V416VL15PHG is strictly a 3.3 V LVTTL device. Its absolute maximum input voltage is VDD + 0.5 V (≤ 4.1 V), and VIH minimum is 2.0 V. Direct connection to 5 V logic violates the VIN rating and risks latch-up or parametric failure. A level-shifting solution is mandatory when interfacing the IDT71V416VL15PHG with 5 V controllers.
What does the "PHG" suffix indicate in IDT71V416VL15PHG?
The "PHG" suffix identifies the package and environmental compliance: "P" = plastic, "H" = 44-pin SOJ (SO44-1), and "G" = lead-free and RoHS-compliant construction. This matches the ordering information diagram in the datasheet (DSC-6478/00, Figure 11a), confirming the device uses matte tin finish and meets EU Directive 2011/65/EU requirements.
Is the IDT71V416VL15PHG pin-compatible with earlier IDT71V416 variants like the VS or S versions?
Yes-the IDT71V416VL15PHG shares identical pinout, signal definitions, and DC/AC timing behavior with other IDT71V416 family members in the 44-pin SOJ package, including IDT71V416VS15PHG and IDT71V416S15PHG. Differences are limited to power consumption (L = low power, S = standard power) and temperature grade (V = industrial, blank = commercial), not pin function or physical layout.
