Product details
Overview
71V416L12BEGI from Renesas Electronics is a 4,194,304-bit (256K × 16) 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 LVTTL-compatible bidirectional I/O, separate high- and low-byte enables (BHE/ BLE), and JEDEC-standard center power/ground pinout for noise reduction. Used in real-time embedded controllers requiring deterministic memory access without refresh.
For engineers reviewing the 71V416L12BEGI datasheet, 71V416L12BEGI pinout, 71V416L12BEGI application, or 71V416L12BEGI equivalent, key selection criteria include industrial-grade timing consistency, byte-selectable write capability, SOJ/TSOP/BGA package compatibility, and low-power standby current (10 mA typical).
Technical Context
The 71V416L12BEGI implements fully static asynchronous logic with no clocks or refresh required. Its address decoding supports 18-bit addressing (A0–A17), enabling direct 256K-word access across the 16-bit data bus (I/O0–I/O15).
It uses dual enable architecture: Chip Select (CS) controls device activation while Output Enable (OE) independently gates output drivers-enabling fast 5 ns OE-to-valid read response. Byte enables (BHE/ BLE) allow independent 8-bit writes without affecting the opposite byte lane.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 256K × 16-bit (4,194,304 bits total); supports word-level random access without wait states. |
| Access Time (tAA) | 12 ns max at VDD = 3.0–3.6 V and –40°C to +85°C; guarantees deterministic latency for hard real-time systems. |
| Supply Voltage | 3.3 V nominal (3.0–3.6 V range); compatible with LVTTL logic families and modern low-voltage system rails. |
| Standby Current (ISB1) | 10 mA max in full standby (CS high, no address transitions); enables low-power hold mode during processor sleep. |
| Input/Output Compatibility | LVTTL-compatible inputs and outputs; VIH = 2.0 V min, VOH = 2.4 V min at IOH = –4 mA ensures robust interfacing with FPGA/CPLD I/O banks. |
| Operating Temperature | –40°C to +85°C industrial grade; validated for use in automotive control units, industrial PLCs, and telecom line cards. |
| Package Type | 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
71V416L12BEGI is packaged in a 48-ball fine-pitch BGA (BEG48) with 9 mm × 9 mm footprint and 0.8 mm ball pitch. Pin 28 is NC or optionally connected to VSS per design flexibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word addressing; all inputs are LVTTL-compatible with 7 pF max input capacitance. |
| CS | Chip Select | Active-low global enable; deactivates internal circuitry and forces I/O into high-Z when high, reducing dynamic current to 10 mA. |
| OE | Output Enable | Active-low output gate; enables data output within 5 ns of assertion, independent of CS timing for flexible bus arbitration. |
| WE | Write Enable | Active-low write strobe; initiates write cycle with 8 ns minimum pulse width; controls data latching on rising edge. |
| BHE / BLE | Byte Enable Inputs | Active-low enables for upper (I/O8–I/O15) and lower (I/O0–I/O7) bytes; allows partial-word writes without read-modify-write overhead. |
| I/O0–I/O15 | Bidirectional Data Bus | 16-bit LVTTL I/O with 8 pF max I/O capacitance; supports concurrent read/write via direction control by WE/OE state. |
| VDD / VSS | Power / Ground | Single 3.3 V supply pair; JEDEC center-power pinout minimizes simultaneous switching noise in high-speed parallel buses. |
Key Features
| Feature | Design Value |
|---|---|
| Industrial temperature support | Rated for –40°C to +85°C operation with guaranteed 12 ns access time across full range-enables deployment in harsh environments without derating. |
| Byte-selectable write capability | Dual independent byte enables (BHE/ BLE) permit 8-bit writes to either half of the 16-bit bus, eliminating unnecessary bus contention in mixed-data-width systems. |
| Low standby power | 10 mA max ISB1 (full static standby) reduces system-level power budget impact during idle cycles-critical for fanless industrial enclosures. |
| LVTTL interface compliance | Guaranteed VIH ≥ 2.0 V and VOL ≤ 0.4 V at 8 mA sink ensure reliable interoperability with Xilinx Artix-7, Intel MAX 10, and Renesas RA MCU I/O banks. |
| 48-ball BGA packaging | BEG48 package provides superior signal integrity and thermal performance over SOJ/TSOP variants, supporting >100 MHz bus clocking in dense routing scenarios. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXI | 512K × 16 organization, 45 ns access, 3.3 V, SOIC-44; higher density but slower timing. | Suitable for non-real-time buffering where latency tolerance exceeds 30 ns. | Select when memory depth > 256K is required and 45 ns access suffices-no PCB redesign needed for SOIC-44 footprint. |
| AS6C4008-12TIN | 256K × 16, 12 ns access, 3.3 V, TSOP-44; identical timing but commercial temp only (0°C to +70°C). | Limited to climate-controlled indoor equipment with no thermal cycling requirements. | Choose for cost-sensitive consumer or test equipment designs where industrial temperature range is not mandated. |
Compared with 71V416L12BEGI, CY62167EV30LL-45ZSXI trades speed for density and package simplicity, while AS6C4008-12TIN matches timing but lacks industrial qualification-making 71V416L12BEGI the sole option for thermally demanding, latency-critical embedded systems requiring both 12 ns access and –40°C support.

FAQ
What is the maximum operating frequency supported by the 71V416L12BEGI?
The 71V416L12BEGI does not operate on a clock; it is an asynchronous SRAM. Its 12 ns access time (tAA) supports effective bus frequencies up to ~83 MHz in worst-case continuous-address scenarios. Cycle time (tRC) is also 12 ns, enabling back-to-back random accesses without inter-cycle delay.
Does the 71V416L12BEGI require external refresh circuitry?
No. The 71V416L12BEGI is a fully static RAM using CMOS latch-based cells. It retains data indefinitely as long as VDD is applied and requires no clocks, timers, or refresh cycles-unlike DRAM or pseudo-SRAM devices.
Can the 71V416L12BEGI be used with 5 V logic interfaces?
No. The 71V416L12BEGI is strictly a 3.3 V LVTTL device. Its absolute maximum input voltage is VDD + 0.5 V (≤4.1 V), and VIH is specified minimum 2.0 V-not compatible with 5 V TTL thresholds. Level-shifting circuitry is required for interfacing with 5 V systems.
What is the function of pin 28 on the BEG48 package of the 71V416L12BEGI?
Pin 28 on the 71V416L12BEGI BEG48 package is designated NC (No Connect), but may optionally be tied to VSS per board layout requirements. This flexibility aids ground plane routing and noise mitigation in high-density designs.
How does the 71V416L12BEGI handle partial-word writes?
The 71V416L12BEGI supports true partial-word writes via dedicated BHE (high byte) and BLE (low byte) inputs. Asserting only one enables writing to I/O8–I/O15 or I/O0–I/O7 independently-eliminating read-modify-write sequences and preserving unselected byte contents.
