Product details
Overview
IDT71V416VL10BEGI from Integrated Device Technology is a 256K × 16-bit (4 Mbit), 3.3V single-supply CMOS static RAM with 10 ns access time, JEDEC-standard center power/ground pinout, and separate high- and low-byte enables-designed for high-speed embedded memory buffering in industrial temperature applications (–40°C to +85°C).
For engineers reviewing the IDT71V416VL10BEGI datasheet, IDT71V416VL10BEGI pinout, IDT71V416VL10BEGI application, or IDT71V416VL10BEGI equivalent, key selection criteria include LVTTL-compatible bidirectional I/O, 5 ns OE-to-output delay, full static asynchronous operation, and SOJ/TSOP/BGA package compatibility across commercial and industrial grades.
Technical Context
The IDT71V416VL10BEGI implements fully static asynchronous circuitry-no clocks or refresh required-and uses IDT's high-reliability CMOS process to achieve guaranteed 10 ns read cycle time (tRC) and address access time (tAA) at industrial temperature range. Its dual byte enable (BHE/BLE) and output enable (OE) support independent 8-bit data access and fast output gating.
Pinout follows JEDEC standard with VDD/VSS on center pins (Pins 12 & 33 in SOJ/TSOP) to minimize switching noise. All inputs and outputs are LVTTL-compatible (VIH = 2.0 V min, VIL = 0.8 V max), and operation is specified over 3.0–3.6 V supply with dynamic current ≤200 mA at fMAX.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4,194,304 bits (256K × 16) |
| Access Time (tAA) | 10 ns - defines minimum latency from address valid to data valid under industrial conditions |
| Supply Voltage | 3.3 V ±10% - single-rail LVTTL-compatible operation without level translation |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded systems |
| I/O Interface | LVTTL-compatible bidirectional I/O0–I/O15 - direct interface with 3.3 V microcontrollers and FPGAs |
| Byte Enables | Separate BHE and BLE inputs - enables independent 8-bit writes without masking logic |
| Output Enable Delay | tOE = 5 ns max - supports tight timing margins in burst-access memory subsystems |
Pinout & Package
Package: 44-pin, 400-mil plastic SOJ (SO44-1) or TSOP Type II (SO44-2); also available in 48-ball BGA (9 mm × 9 mm). This entry corresponds to the SOJ/TSOP variant per ordering suffix "BEGI" (Industrial, SOJ).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word addressing |
| CS | Chip Select | Active-low global enable; deassertion places device in standby (ISB1 ≤ 10 mA) |
| OE | Output Enable | Active-low control of output drivers; enables fast read gating (tOE ≤ 5 ns) |
| WE | Write Enable | Active-low write strobe; controls direction and latching of I/O lines |
| BHE / BLE | High/Low Byte Enable | Independent 8-bit write control for upper (I/O8–I/O15) and lower (I/O0–I/O7) bytes |
| I/O0–I/O15 | Bidirectional Data | LVTTL-compatible data bus; high-impedance when CS, OE, BHE, or BLE inactive |
| VDD | Power Supply | 3.3 V core and I/O supply; Pins 12 and 33 (center location) reduce noise coupling |
| VSS | Ground | Ground reference; Pins 11 and 34 (center location) ensure low-inductance return path |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Center Power/Ground Pinout | Reduces simultaneous switching noise by symmetrically placing VDD/VSS near center of SOJ/TSOP package |
| Full Static Asynchronous Operation | Eliminates need for clocks, refresh controllers, or timing-critical initialization sequences |
| Low-Power Standby Mode | ISB1 ≤ 10 mA at full VDD ensures minimal power draw during system sleep states |
| 5 ns Output Enable Response | Enables interleaved read cycles with sub-10 ns turnaround in multi-port memory arbitration |

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-10ZSXI | 4 Mbit (256K × 16), 10 ns, 3.3 V, but uses different pinout (no center VDD/VSS) and lacks BHE/BLE | Requires PCB redesign due to non-JEDEC pin assignment; no native byte-write capability | Select only if board layout allows re-routing and byte masking is handled externally |
| AS6C4008-10BIN | 4 Mbit (256K × 16), 10 ns, 3.3 V, SOJ package, but rated only for commercial temp (0°C to +70°C) | Not qualified for industrial environments; higher ISB1 (25 mA) increases standby power | Acceptable only for cost-sensitive commercial designs with ambient thermal control |
Compared with CY62148EV30LL-10ZSXI and AS6C4008-10BIN, the IDT71V416VL10BEGI provides JEDEC-compliant noise-reducing pinout, true independent byte enables, and industrial temperature assurance-making it uniquely suitable for ruggedized embedded memory subsystems without layout or thermal compromises.

FAQ
What is the operating temperature range for IDT71V416VL10BEGI?
IDT71V416VL10BEGI 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 (tAA ≤ 10 ns), standby current (ISB1 ≤ 10 mA), and input/output voltage thresholds. The "I" in the part number explicitly denotes industrial grade, distinguishing it from commercial variants like IDT71V416VS10BGI.
Does IDT71V416VL10BEGI require a clock or refresh signal?
No, IDT71V416VL10BEGI uses fully static asynchronous circuitry and requires no clock, refresh controller, or periodic maintenance cycles. Data retention is indefinite as long as VDD is applied and ambient temperature remains within spec. This eliminates timing-critical initialization sequences and simplifies integration into FPGA- or microcontroller-based systems where deterministic latency is essential.
What package type does IDT71V416VL10BEGI use?
IDT71V416VL10BEGI uses a 44-pin, 400-mil plastic SOJ (Small Outline J-lead) package, designated SO44-1 in IDT documentation. The "BEGI" suffix confirms SOJ packaging, industrial temperature grade, and lead-free (RoHS-compliant) construction. It is pin-compatible with the 44-pin TSOP Type II variant (SO44-2) except for lead geometry and mechanical footprint.
How does the byte enable functionality work on IDT71V416VL10BEGI?
IDT71V416VL10BEGI features two independent byte enable inputs: BHE (high byte enable) for I/O8–I/O15 and BLE (low byte enable) for I/O0–I/O7. When only one is asserted low during a write cycle, only the corresponding 8-bit byte is written; both must be low for full 16-bit word writes. This eliminates need for external byte masking logic and supports mixed-width data transfers common in legacy 8-bit peripheral interfaces.
Is IDT71V416VL10BEGI compatible with 3.3 V LVTTL logic families?
Yes, IDT71V416VL10BEGI is fully LVTTL-compatible: inputs accept VIH ≥ 2.0 V and VIL ≤ 0.8 V, outputs drive VOH ≥ 2.4 V (at –4 mA) and VOL ≤ 0.4 V (at 8 mA) over the full industrial temperature range and 3.0–3.6 V supply. No level shifters are needed when interfacing with Spartan-6 FPGAs, i.MX6 processors, or other 3.3 V LVTTL peripherals.
