Product details
Overview
IDT71V416VS10PHG from Integrated Device Technology is a 256K × 16-bit (4 Mbit), 3.3V CMOS static RAM with 10 ns access time, JEDEC-compliant center-power/ground pinout, and LVTTL-compatible bidirectional I/O. It operates across commercial temperature range (0°C to +70°C), supports byte-wide or full-word read/write via BHE/BLE, and targets high-speed embedded memory buffering in networking and industrial controllers.
For engineers reviewing the IDT71V416VS10PHG datasheet, IDT71V416VS10PHG pinout, IDT71V416VS10PHG application, or IDT71V416VS10PHG equivalent, key selection criteria include its 10 ns read cycle time, single-supply 3.3V operation, SOJ-44 package compatibility, and byte-enable-controlled partial-word access capability.
Technical Context
The IDT71V416VS10PHG implements fully static asynchronous circuitry-no clocks or refresh required-and uses IDT's high-reliability CMOS process for stable operation at up to 100 MHz effective bandwidth. Its dual-byte enable (BHE/BLE) and output enable (OE) support independent high- and low-byte access with 5 ns OE-to-output delay.
Address decoding covers A0–A17 (18-bit), enabling full 256K-word addressing; all control inputs (CS, WE, OE, BHE, BLE) are LVTTL-compatible with VIH ≥ 2.0 V and VIL ≤ 0.8 V. The device features dynamic standby current of 70 mA max and full static standby current of 20 mA max at VDD = 3.6 V.

|---|---|---|---|
| CY62148EV30LL-10ZSXI | 4 Mbit (256K × 16), 10 ns, 3.3V, SOJ-44 - identical speed/package but Cypress's low-power design draws 180 mA max ICC vs. 200 mA | Lower dynamic power suits battery-backed or thermally constrained systems; same pinout and timing interface | Select when standby current <60 mA is required and Cypress qualification is accepted |
| AS6C4008-10BIN | 4 Mbit (256K × 16), 10 ns, 3.3V, SOJ-44 - Alliance Memory part with 100% functional equivalence but different DC leakage specs (±10 µA vs. ±5 µA) | Drop-in replacement for cost-sensitive volume production where extended temp range not needed | Choose for legacy design refresh where sourcing continuity and price drive decisions over minor parametric variance |
Compared with CY62148EV30LL-10ZSXI and AS6C4008-10BIN, the IDT71V416VS10PHG offers tighter input/output leakage (±5 µA), higher noise immunity via JEDEC-compliant pinout, and broader industrial qualification history-making it preferred for mission-critical commercial infrastructure.

FAQ
What is the operating temperature range for the IDT71V416VS10PHG?
The IDT71V416VS10PHG is rated for commercial temperature operation from 0°C to +70°C. This range is explicitly defined in the ordering code suffix 'C' (implied in 'VS'), and confirmed by the datasheet's Recommended Operating Conditions table. It is not qualified for industrial (-40°C to +85°C) use-designers requiring wider temperature tolerance should select the IDT71V416VL variant instead. The IDT71V416VS10PHG maintains full AC/DC specifications across this entire commercial range.
Does the IDT71V416VS10PHG require a refresh circuit or clock signal?
No, the IDT71V416VS10PHG is a fully static asynchronous SRAM and requires neither a clock nor refresh circuitry. Its internal design uses bistable latches for data retention, enabling indefinite data hold as long as power and valid control signals are maintained. This eliminates timing-critical initialization sequences and simplifies integration with microcontrollers, FPGAs, or ASICs lacking dedicated memory controllers. The IDT71V416VS10PHG operates reliably under these conditions across its full commercial temperature range.
What package type does the IDT71V416VS10PHG use, and is it lead-free?
The IDT71V416VS10PHG uses a 44-pin, 400-mil plastic SOJ (Small Outline J-lead) package, designated SO44-1 in the datasheet. The 'G' suffix in the part number confirms RoHS-compliant, lead-free construction per IDT's hazardous substance policy. Pin pitch is 0.05 inches (1.27 mm), and body width is 400 mils (10.16 mm), matching JEDEC MO-050 standards. This package supports wave or reflow soldering and is compatible with standard SOJ socket footprints.
Can the IDT71V416VS10PHG perform byte-wide writes without affecting adjacent bytes?
Yes, the IDT71V416VS10PHG supports true independent byte writes using its dedicated BHE (high-byte enable) and BLE (low-byte enable) inputs. When only BHE is asserted (low), data on I/O8–I/O15 is written while I/O0–I/O7 remains unchanged; conversely, asserting only BLE writes to I/O0–I/O7. This functionality is verified in the Truth Table and timing diagrams, and eliminates the need for external read-modify-write logic. The IDT71V416VS10PHG delivers this capability with guaranteed 10 ns write cycle time for both full-word and byte operations.
What is the maximum output drive strength of the IDT71V416VS10PHG I/O pins?
The IDT71V416VS10PHG I/O pins provide LVTTL-compatible drive strength: VOH ≥ 2.4 V at IOH = –4 mA (high-level output) and VOL ≤ 0.4 V at IOL = 8 mA (low-level output), tested at minimum VDD (3.0 V). These values ensure robust noise margins when interfacing with standard 3.3V logic families. The device does not support higher-current drivers (e.g., 24 mA) or bus-hold features-the IDT71V416VS10PHG relies on clean board-level termination and proper signal routing for signal integrity.
