Product details
Overview
IDT71V416VL12BEI8 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 industrial temperature range (–40°C to +85°C). It supports byte-wide and word-wide read/write operations via independent BHE/BLE controls and operates asynchronously without clocks or refresh.
For engineers reviewing the IDT71V416VL12BEI8 datasheet, IDT71V416VL12BEI8 pinout, IDT71V416VL12BEI8 application, or IDT71V416VL12BEI8 equivalent, key selection factors include its 12 ns read cycle time, LVTTL-compatible I/Os, low-power standby current (max 60 mA), and SOJ/TSOP/BGA package options for space-constrained embedded memory subsystems.
Technical Context
The IDT71V416VL12BEI8 implements fully static asynchronous circuitry with no clock or refresh requirement. Its dual-byte enable architecture (BHE/BLE) enables independent high- and low-byte access, while OE-controlled output timing achieves 6 ns output enable delay (tOE) and 6 ns high-impedance transition (tOHZ).
It uses IDT's high-reliability CMOS process and features JEDEC-standard pinout for noise reduction. All inputs and outputs are LVTTL-compatible, and operation is guaranteed across VDD = 3.0–3.6 V with full DC and AC specifications validated over –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 256K × 16-bit (4,194,304-bit) organization - supports 16-bit data bus interfacing without external multiplexing. |
| Access Time | 12 ns (tAA, tACS) - ensures compatibility with 83 MHz bus systems requiring deterministic read latency. |
| Supply Voltage | 3.3 V ±10% (3.0–3.6 V) - compatible with modern low-voltage logic families and eliminates level-shifting in 3.3V systems. |
| Standby Current | Max 60 mA (ISB, industrial grade) - enables low-power hold mode during processor sleep or system idle states. |
| I/O Interface | LVTTL-compatible bidirectional I/Os - directly interfaces with 3.3V microcontrollers, FPGAs, and ASICs without external buffers. |
| Operating Temp | –40°C to +85°C - qualified for industrial control, networking equipment, and automotive under-hood auxiliary modules. |
| Package | 44-pin, 400-mil SOJ (SO44-1) - surface-mount, leaded package with proven reliability in reflow-soldered industrial PCBs. |
Pinout & Package
Package: 44-pin, 400-mil plastic SOJ (SO44-1), JEDEC-standard center power/ground layout for reduced switching noise and improved signal integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word decoding; A0–A17 directly map to memory row/column selection. |
| CS | Chip Select | Active-low enable controlling device participation in bus cycles; deassertion places all outputs in high-Z. |
| OE | Output Enable | Active-low control enabling output drivers only during read operations; decouples read timing from CS. |
| WE | Write Enable | Active-low write strobe; latches data on I/O pins when CS and byte enables are active. |
| BHE / BLE | Byte Enable | Independent high- and low-byte controls allowing 8-bit sub-word writes without disturbing adjacent bytes. |
| I/O0–I/O15 | Bidirectional Data | 16-bit LVTTL I/O bus; direction controlled by WE state and internal read/write logic. |
| VDD / VSS | Power / Ground | Center-placed VDD (pins 12, 33) and VSS (pins 11, 34) minimize simultaneous switching noise per JEDEC standard. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Center Power/Ground Pinout | Reduces ground bounce and supply noise by symmetrically distributing VDD/VSS pins across the package center. |
| Dual Byte Enable (BHE/BLE) | Enables selective 8-bit writes to upper or lower byte without read-modify-write overhead or bus contention. |
| Low-Power Standby Mode | Draws ≤60 mA (industrial) when CS inactive - extends battery life in portable instrumentation and remote sensors. |
| 12 ns Access + 12 ns Cycle | Guaranteed tAA and tRC of 12 ns enables tight timing closure in FPGA-based memory controllers and legacy bus interfaces. |
| Single 3.3V Supply Operation | Eliminates need for dual-supply regulators or level shifters in mixed-voltage systems, reducing BOM cost and board area. |

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), 12 ns, 3.3V, SOJ-44, but uses Cypress's "LL" low-power core (ISB1 = 5 µA vs. IDT71V416VL12BEI8's 10 mA). | Lower standby current suits battery-backed systems; lacks BHE/BLE - requires external byte masking logic for sub-word writes. | Select when ultra-low static power dominates over byte-select flexibility and industrial temp is not required. |
| AS6C4008-12ZIN | 4 Mbit (256K × 16), 12 ns, 3.3V, SOJ-44, but rated only for commercial temp (0°C to +70°C); ICC max = 180 mA (vs. 180 mA for IDT71V416VL12BEI8 industrial grade). | Not qualified for industrial ambient; identical AC timing and pinout, but no BGA option available. | Select for cost-sensitive commercial equipment where extended temperature range is unnecessary and BGA packaging is not needed. |
Compared with CY62148EV30LL-12ZSXI and AS6C4008-12ZIN, the IDT71V416VL12BEI8 uniquely combines industrial temperature qualification, JEDEC-compliant noise-reducing pinout, and hardware byte enable support - making it optimal for mission-critical embedded systems requiring robustness and design simplicity.

FAQ
What is the maximum operating temperature range for the IDT71V416VL12BEI8?
The IDT71V416VL12BEI8 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 levels. The "I" suffix in the part number explicitly denotes industrial qualification, making IDT71V416VL12BEI8 suitable for deployment in harsh environments such as factory automation cabinets or outdoor telecom infrastructure.
Does the IDT71V416VL12BEI8 require a clock or refresh circuit?
No, the IDT71V416VL12BEI8 uses fully static asynchronous circuitry and requires neither a clock nor periodic refresh. Data retention is maintained indefinitely as long as VDD remains within 3.0–3.6 V and the device is not actively written to. This eliminates timing complexity in microcontroller-based systems and avoids hidden refresh overhead in FPGA memory controllers - a key advantage over DRAM or pseudo-SRAM solutions.
What package type does the IDT71V416VL12BEI8 use, and is it lead-free?
The IDT71V416VL12BEI8 uses a 44-pin, 400-mil plastic SOJ (SO44-1) package. Per the ordering information in the datasheet, the "G" suffix is omitted, confirming this variant is not restricted-hazardous-substance compliant; however, the "E" in the suffix indicates lead-free termination (Pb-free leads with matte tin plating), verified per J-STD-609. The SOJ package supports standard reflow profiles and is widely supported by industrial PCB assembly houses.
Can the IDT71V416VL12BEI8 perform byte-level writes without reading first?
Yes, the IDT71V416VL12BEI8 supports true byte-level writes via dedicated BHE (high byte enable) and BLE (low byte enable) pins. When only BHE is asserted (BLE inactive), only I/O8–I/O15 are written; when only BLE is asserted (BHE inactive), only I/O0–I/O7 are written. This occurs in a single write cycle with no read-modify-write sequence required, preserving adjacent byte integrity and reducing bus arbitration overhead in multi-master systems.
What is the minimum VDD supply voltage required for reliable operation of the IDT71V416VL12BEI8?
The IDT71V416VL12BEI8 requires a minimum VDD of 3.0 V for guaranteed operation across its full industrial temperature range (–40°C to +85°C). At 3.0 V, all AC timing parameters (including 12 ns tAA and tRC), DC output drive (VOL ≤ 0.4 V at 8 mA), and input thresholds (VIH ≥ 2.0 V) remain within specification. Operating below 3.0 V risks timing violations, increased leakage, or data corruption and is not supported.
