Product details
Overview
71V416L12BEGI8 from Renesas is a 4-Mbit (256K × 16) low-power, high-speed CMOS static RAM with 12 ns access time, single 3.3 V supply operation, and industrial temperature range (–40°C to +85°C). It features separate byte enable pins (BHE/BLE), LVTTL-compatible I/Os, and JEDEC-standard center power/ground pinout for noise reduction - deployed in embedded control, industrial PLCs, and legacy bus-based data acquisition systems.
For engineers reviewing the 71V416L12BEGI8 datasheet, 71V416L12BEGI8 pinout, 71V416L12BEGI8 application, or 71V416L12BEGI8 equivalent, key selection criteria include its 12 ns read cycle time, low standby current (45 mA dynamic, 10 mA static), 48-ball BGA (BEG48) package with 9 mm × 9 mm footprint, and support for word/byte-level write control without external logic.
Technical Context
The 71V416L12BEGI8 implements fully static asynchronous architecture with no clocks or refresh required. Its dual-byte enable (BHE/BLE) and independent output enable (OE) allow selective 8-bit or 16-bit read/write operations while maintaining full address/data bus compatibility with legacy 16-bit microcontrollers and DSPs.
It uses high-reliability CMOS process technology optimized for stable operation across industrial temperature extremes. The device supports three distinct write control modes - WE-controlled, CS-controlled, and byte-enable-controlled - each with defined timing constraints (e.g., tWP = 8 ns min, tDW = 6 ns min) verified under AC test loads of 30 pF and 50 Ω.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4,194,304 bits (256K × 16), enabling direct replacement of legacy 256K-word SRAMs in 16-bit data bus systems. |
| Access Time | 12 ns max (tAA, tACS), ensuring compatibility with 83 MHz bus timing budgets in industrial microcontroller interfaces. |
| Supply Voltage | 3.0 V to 3.6 V - operates reliably across wide 3.3 V rail tolerances common in industrial power supplies. |
| Standby Current | 10 mA max (ISB1), reducing system-level power consumption during idle states in battery-backed or energy-sensitive applications. |
| I/O Interface | LVTTL-compatible bidirectional data (I/O0–I/O15), eliminating level-shifter requirements when interfacing with 3.3 V logic families. |
| Operating Temperature | –40°C to +85°C, qualified for use in uncontrolled industrial enclosures and outdoor automation equipment. |
| Package | 48-ball BGA (BEG48), 9 mm × 9 mm, 0.8 mm pitch - supports high-density PCB layouts with improved thermal dissipation vs. SOJ/TSOP. |
Pinout & Package
71V416L12BEGI8 is packaged in a 48-ball grid array (BEG48) with 9 mm × 9 mm body size and 0.8 mm ball pitch. Pin assignments follow standard BEG48 layout per Renesas documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word addressing; compatible with 16-bit microprocessor address latches. |
| CS | Chip Select | Active-low enable controlling entire memory array; used for bank selection in multi-SRAM systems. |
| WE | Write Enable | Active-low signal initiating write cycles; timing-critical for meeting tWP (8 ns min) and tDW (6 ns min) requirements. |
| OE | Output Enable | Active-low control for output drivers; enables tristate behavior during reads without affecting write operations. |
| BHE / BLE | Byte Enable | Independent high- and low-byte controls allowing 8-bit writes to upper or lower half of 16-bit word - eliminates need for external byte-masking logic. |
| I/O0–I/O15 | Bidirectional Data | 16-bit LVTTL I/O bus; direction controlled by WE/OE state - simplifies interface design in synchronous and asynchronous bus architectures. |
| VDD / VSS | Power / Ground | Center-placed VDD/VSS pins per JEDEC standard reduce simultaneous switching noise on 3.3 V supply rails. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| CY62167EV30LL-45ZSXI | 4-Mbit (256K × 16), 45 ns access, 3.3 V, SOIC-44 package; higher access time, larger footprint, no byte enables. | Suitable for cost-sensitive, non-timing-critical upgrades where board space permits SOIC and slower speed is acceptable. | Select only if 12 ns timing is not required and SOIC layout already exists. |
| AS6C4008-12TIN | 4-Mbit (512K × 8), 12 ns, 3.3 V, TSOP-44; 8-bit bus width, no BHE/BLE, different address depth (19-bit). | Requires bus-width adaptation (e.g., two devices for 16-bit) and address decoding changes; suited for new designs targeting 8-bit microcontrollers. | Choose only when redesigning for 8-bit architecture or when TSOP-44 is mandatory for rework compatibility. |
Compared with CY62167EV30LL-45ZSXI and AS6C4008-12TIN, the 71V416L12BEGI8 uniquely delivers 12 ns performance in a compact BGA with native 16-bit byte masking - making it the only drop-in solution for industrial systems requiring both speed, density, and minimal PCB footprint.

FAQ
What is the maximum operating frequency supported by the 71V416L12BEGI8?
The 71V416L12BEGI8 does not operate on a clock but supports asynchronous bus frequencies up to approximately 83 MHz, derived from its 12 ns read cycle time (tRC). This enables direct interfacing with microcontrollers and DSPs using 16-bit parallel buses without external wait-state generation in most industrial timing budgets.
Does the 71V416L12BEGI8 require external refresh circuitry?
No, the 71V416L12BEGI8 is a fully static RAM and requires no refresh cycles or clocks. Its CMOS latch-based memory cells retain data indefinitely as long as VDD is applied within specification (3.0 V–3.6 V), making it ideal for deterministic real-time systems where refresh-induced latency or jitter is unacceptable.
Can the 71V416L12BEGI8 be used with 5 V logic interfaces?
No - the 71V416L12BEGI8 is strictly a 3.3 V LVTTL device. Its absolute maximum input voltage is VDD + 0.5 V (≤4.1 V), and VIH minimum is 2.0 V. Interfacing with 5 V logic requires level translation; direct connection risks damage and violates DC operating conditions specified in the Renesas datasheet.
What is the significance of the "BEGI8" suffix in 71V416L12BEGI8?
The "BEGI8" suffix denotes: BE = 48-ball BGA package, G = green (lead-free), I = industrial temperature grade (–40°C to +85°C), and 8 = tape-and-reel packaging. This confirms the device is RoHS-compliant, qualified for harsh environments, and supplied in machine-ready format for SMT assembly.
How does the 71V416L12BEGI8 handle partial-word writes?
The 71V416L12BEGI8 supports true partial-word writes via dedicated BHE (high byte) and BLE (low byte) inputs. When only one is asserted low with WE low, only the corresponding 8-bit byte is written; the other remains unchanged - eliminating the need for read-modify-write sequences or external byte-mask logic in 16-bit systems.
