Product details
Overview
IDT71V416VS12PH8 from Integrated Device Technology is a 256K × 16-bit (4 Mbit), 3.3V CMOS static RAM with 12 ns access time, JEDEC-compliant center power/ground pinout, and LVTTL-compatible bidirectional I/O. It operates across industrial temperature range (–40°C to +85°C), supports byte-wide and word-wide read/write via BHE/BLE, and targets high-speed embedded memory buffering in networking and industrial control systems.
For engineers reviewing the IDT71V416VS12PH8 datasheet, IDT71V416VS12PH8 pinout, IDT71V416VS12PH8 application, or IDT71V416VS12PH8 equivalent, key selection criteria include its 12 ns tAA/tRC timing, SOJ-44 package with VDD/VSS symmetry, dual-byte enable architecture, and low-power standby current of 60 mA max under dynamic conditions.
Technical Context
The IDT71V416VS12PH8 implements fully static asynchronous operation-no clocks or refresh required-and uses dedicated OE, CS, WE, BHE, and BLE control logic to manage output enable, chip select, write strobing, and high/low byte masking independently. Its address decoding covers A0–A17 for full 256K-word addressing.
All I/Os are LVTTL-compatible with VIH ≥ 2.0 V and VIL ≤ 0.8 V at VDD = 3.0–3.6 V; input/output capacitance is characterized at 7 pF (CIN) and 8 pF (CI/O). The device supports three distinct write control modes: WE-controlled, CS-controlled, and BHE/BLE-controlled, each with defined timing constraints per AC table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 256K × 16-bit (4,194,304-bit total); enables 16-bit data bus interfacing without external multiplexing. |
| Access Time (tAA) | 12 ns max; determines minimum address-to-data valid delay in read cycles for real-time system timing budgets. |
| Cycle Time (tRC) | 12 ns max; defines shortest interval between successive read or write operations on same address space. |
| Supply Voltage | 3.0–3.6 V; single-rail compatibility with 3.3V logic families eliminates level-shifting requirements. |
| Standby Current (ISB) | 60 mA max (industrial grade); enables low-power sleep mode in battery-backed or energy-sensitive applications. |
| Operating Temperature | –40°C to +85°C; qualified for industrial environments including factory automation and telecom infrastructure. |
| I/O Interface | LVTTL-compatible with VOH ≥ 2.4 V @ –4 mA and VOL ≤ 0.4 V @ 8 mA; ensures robust noise margin in noisy PCB layouts. |
Pinout & Package
Package: 44-pin, 400-mil plastic SOJ (SO44-1), JEDEC-standard center power/ground layout for reduced switching noise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word decode; no internal latching required. |
| CS | Chip Select | Active-low enable for device selection; must be stable before address setup to meet tAS = 0 ns. |
| OE | Output Enable | Active-low control for tri-state output drivers; tOE = 6 ns max ensures fast data release from memory array. |
| WE | Write Enable | Active-low write strobe; initiates write cycle when combined with CS and BHE/BLE assertion. |
| BHE / BLE | Byte Enable | Independent high/low byte masking; allows 8-bit sub-word writes without disturbing adjacent byte. |
| I/O0–I/O15 | Bidirectional Data | 16-bit LVTTL I/O bus; direction controlled by WE/CS/OE state per truth table; no external transceivers needed. |
| VDD / VSS | Power / Ground | Paired center pins (Pin 12 & 33 VDD; Pin 11 & 34 VSS) minimize IR drop and ground bounce in high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Center Power/Ground Pinout | Reduces simultaneous switching noise (SSN) by symmetric VDD/VSS placement-critical for signal integrity in dense PCBs. |
| Dual Byte Enable (BHE/BLE) | Enables selective 8-bit writes to upper or lower byte without read-modify-write overhead or bus contention. |
| Equal Access & Cycle Times | 12 ns tAA = tRC guarantees deterministic timing for both reads and writes-simplifies worst-case timing analysis. |
| Low-Power Standby Mode | ISB ≤ 60 mA (industrial) with CS high; cuts dynamic power >70% vs active mode while retaining data. |
| Fully Static Operation | No clocks, no refresh cycles required-eliminates timing controller complexity and reduces system-level jitter. |

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 |
|---|---|---|---|
| CY62148EV30LL-12ZSXI | 4 Mbit (256K × 16), 3.3V, 12 ns, SOJ-44-but uses different byte enable logic (UB/LB vs BHE/BLE) and lacks JEDEC center power pinout. | Requires PCB layout revision due to non-identical pin mapping; not drop-in for IDT71V416VS12PH8's VDD/VSS symmetry. | Select only if redesign accommodates altered power/ground placement and byte enable signal routing. |
| AS6C4008-12ZIN | 4 Mbit (256K × 16), 3.3V, 12 ns, SOJ-44-but specifies 70 mA ISB (vs 60 mA), wider VDD tolerance (2.7–3.6 V), and no industrial temp guarantee beyond –40°C to +85°C. | Suitable for commercial-temp designs with relaxed power budget; not recommended for extended industrial thermal cycling. | Prefer for cost-sensitive commercial applications where full industrial qualification is unnecessary. |
Compared with CY62148EV30LL-12ZSXI and AS6C4008-12ZIN, the IDT71V416VS12PH8 delivers tighter ISB control, JEDEC-optimized noise suppression, and verified industrial-grade reliability-making it optimal for mission-critical embedded systems where timing determinism and thermal stability are non-negotiable.

FAQ
What is the operating temperature range for the IDT71V416VS12PH8?
The IDT71V416VS12PH8 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 I/O voltage thresholds. The "I" suffix in the part number explicitly denotes industrial qualification, and thermal performance is validated per JEDEC JESD22-A104 and JESD22-A108 standards.
Does the IDT71V416VS12PH8 require a refresh circuit or clock signal?
No, the IDT71V416VS12PH8 is a fully static RAM and requires no refresh circuitry or clock signal. Its internal design uses static CMOS latches for data retention, enabling indefinite data hold as long as VDD remains within 3.0–3.6 V and ambient temperature stays within –40°C to +85°C. This eliminates timing controller overhead and reduces system-level jitter in deterministic real-time applications.
What package type does the IDT71V416VS12PH8 use, and is it lead-free?
The IDT71V416VS12PH8 uses a 44-pin, 400-mil plastic SOJ (SO44-1) package with JEDEC-standard center power/ground pinout. Per the ordering information in the datasheet, the "G" suffix would indicate RoHS-compliant construction-but the IDT71V416VS12PH8 lacks that suffix, confirming it is a legacy non-RoHS part with SnPb terminations. Full compliance documentation is available upon request for legacy program support.
How does the byte enable functionality work on the IDT71V416VS12PH8?
The IDT71V416VS12PH8 implements independent high-byte enable (BHE) and low-byte enable (BLE) inputs to support 8-bit sub-word writes. 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 write. This eliminates read-modify-write cycles and reduces bus arbitration latency in multi-master systems.
What is the maximum dynamic operating current (ICC) for the IDT71V416VS12PH8 at 12 ns speed?
The maximum dynamic operating current (ICC) for the IDT71V416VS12PH8 at 12 ns speed grade is 180 mA under industrial conditions (–40°C to +85°C), measured with CS < VLC, outputs open, VDD at maximum (3.6 V), and address inputs cycling at fMAX = 1/tRC. This value is specified in Table 8 of the datasheet and reflects worst-case power draw during sustained burst read/write activity.
