Product details
Overview
IDT71V416VL10PHG8 from Integrated Device Technology is a 256K × 16-bit (4 Mbit), 3.3V single-supply CMOS static RAM with 10 ns access time, JEDEC-compliant center power/ground pinout, and LVTTL-compatible bidirectional I/Os. It supports byte-wide or word-wide read/write operations via independent BHE/BLE controls and operates across industrial temperature range (–40°C to +85°C) in a 44-pin 400-mil plastic SOJ package.
For engineers reviewing the IDT71V416VL10PHG8 datasheet, IDT71V416VL10PHG8 pinout, IDT71V416VL10PHG8 application, or IDT71V416VL10PHG8 equivalent, key selection criteria include industrial-grade timing consistency (tAA ≤ 10 ns), low-power standby current (ISB1 ≤ 10 mA), byte-select capability, and SOJ package compatibility with legacy memory sockets in embedded controllers and telecom line cards.
Technical Context
The IDT71V416VL10PHG8 implements fully static asynchronous logic with no clocks or refresh required. Its architecture includes separate high- and low-byte enable paths (BHE/BLE), independent chip select (CS) and output enable (OE) controls, and bidirectional I/O buffers directly compatible with LVTTL voltage levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V).
Timing is defined by overlapping control signals: read cycles require CS and OE low with WE high; write cycles require CS, WE, and at least one byte enable low. Output enable propagation delay is guaranteed ≤5 ns, and chip select disable-to-high-Z transition is ≤5 ns under industrial conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 256K × 16-bit (4,194,304-bit total); supports 16-bit data bus interfacing without external multiplexing |
| Access Time (tAA) | ≤10 ns at VDD = 3.0–3.6 V, –40°C to +85°C; enables tight timing margins in 100 MHz bus systems |
| Supply Voltage | 3.3 V nominal (3.0–3.6 V range); eliminates need for dual-voltage rails in LVTTL-based designs |
| Standby Current (ISB1) | ≤10 mA max at VDD = max, f = 0; ensures low quiescent power during system sleep modes |
| I/O Compatibility | LVTTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and output drive (VOH ≥ 2.4 V @ –4 mA, VOL ≤ 0.4 V @ 8 mA) |

| Package | 44-pin plastic SOJ (SO44-1), 400-mil width; footprint-compatible with JEDEC MS-024 standard sockets |
Pinout & Package
44-pin plastic SOJ (SO44-1) package with 400-mil body width, JEDEC-standard center power/ground pinout (VDD on pins 12 & 33, VSS on pins 11 & 34) minimizing simultaneous switching noise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word decoding; A0–A15 select word, A16/A17 unused in 256K×16 config |
| CS | Chip Select | Active-low enable for device selection; must be low before or coincident with address valid for tAA timing compliance |
| OE | Output Enable | Active-low control of output drivers; enables shared-bus operation with ≤5 ns enable-to-valid delay |
| WE | Write Enable | Active-low write strobe; combined with CS and byte enables to initiate write cycles without requiring address hold |
| BHE / BLE | Byte Enable | Independent high- and low-byte controls; allow 8-bit sub-word writes without disturbing adjacent byte |
| I/O0–I/O15 | Bidirectional Data | LVTTL-compatible 16-bit data bus; tristated when CS high or OE high, driven during read/write per byte enable state |
| VDD | Power Supply | 3.3 V supply (pins 12, 33); center placement reduces IR drop and ground bounce in high-speed operation |
| VSS | Ground | Ground reference (pins 11, 34); paired with VDD per JEDEC noise-reduction layout convention |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Center Power/Ground Pinout | Reduces simultaneous switching noise by symmetrically distributing VDD/VSS pins across package centerline |
| Independent Byte Enables (BHE/BLE) | Enables selective 8-bit writes to upper or lower byte without read-modify-write overhead |
| Low-Power Standby Mode (ISB1) | 10 mA max static current allows battery-backed operation in industrial backup memory applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62148EV30LL-10ZSXI | 4 Mbit (256K×16), 10 ns, 3.3 V, SOJ-44, but rated only for industrial –40°C to +85°C with higher ISB1 (25 mA) | Higher standby current limits battery-backed runtime; identical pinout and timing allow drop-in replacement where power budget permits | Select when Cypress qualification documentation is required for aerospace programs, accepting higher ISB1 trade-off |
| AS6C4008-10PCN | 4 Mbit (256K×16), 10 ns, 3.3 V, SOJ-44, but lacks BHE/BLE - uses single byte enable (UB/LB) with different pin mapping | Requires PCB layout change due to non-identical pinout (e.g., UB/LB vs BHE/BLE placement); no JEDEC center power/ground | Select only for new designs where simplified byte control suffices and layout revision is acceptable |
Compared with CY62148EV30LL-10ZSXI and AS6C4008-10PCN, the IDT71V416VL10PHG8 offers lower industrial standby current (10 mA vs 25 mA/-) and JEDEC-optimized pinout for noise-sensitive applications, though AS6C4008 requires board redesign due to incompatible byte enable pin assignment.

FAQ
What is the operating temperature range specified for the IDT71V416VL10PHG8?
The IDT71V416VL10PHG8 is rated for industrial temperature operation from –40°C to +85°C. This range is explicitly confirmed in the ordering information ('I' suffix) and DC/AC electrical characteristics tables, ensuring guaranteed timing (tAA ≤ 10 ns) and parametric performance across the full span without derating.
Does the IDT71V416VL10PHG8 require a refresh circuit or clock signal?
No, the IDT71V416VL10PHG8 is a fully static RAM and requires no refresh circuitry or clock signal. Its internal design uses static latches and asynchronous control logic, allowing indefinite data retention as long as power is applied and CS remains high during standby - a key advantage over DRAM in deterministic embedded systems.
How does the byte enable functionality work on the IDT71V416VL10PHG8?
The IDT71V416VL10PHG8 uses two dedicated inputs - BHE (pin 36) for high byte (I/O8–I/O15) and BLE (pin 35) for low byte (I/O0–I/O7). When either is low (with CS and WE low), only the corresponding 8-bit group is written; both must be low for full 16-bit word writes. This avoids read-modify-write cycles in partial updates.
Is the IDT71V416VL10PHG8 pin-compatible with other speed grades in the same family?
Yes, all IDT71V416VL variants (e.g., L12, L15) share identical 44-pin SOJ pinouts and signal assignments. The '10' in IDT71V416VL10PHG8 denotes 10 ns speed grade, but mechanical and electrical pin compatibility is maintained across L10/L12/L15 industrial versions, enabling timing-based upgrades without PCB changes.
What is the maximum output drive strength supported by the IDT71V416VL10PHG8 I/O pins?
The IDT71V416VL10PHG8 guarantees VOH ≥ 2.4 V at IOH = –4 mA and VOL ≤ 0.4 V at IOL = 8 mA under minimum VDD (3.0 V) and industrial temperature extremes. These values confirm robust LVTTL-compatible drive strength sufficient to fan-out to multiple 74LVC-series inputs without buffering.
