Product details
Overview
71V416L10BE8 from Renesas Electronics is a 4-Mbit (256K × 16) low-power, high-speed CMOS static RAM with 10 ns access time, single 3.3 V supply operation, LVTTL-compatible I/O, and JEDEC-standard center power/ground pinout for noise reduction. It serves as a non-refreshing, fully static asynchronous memory buffer in embedded controllers, network interface cards, and real-time data acquisition systems.
For engineers reviewing the 71V416L10BE8 datasheet, 71V416L10BE8 pinout, 71V416L10BE8 application, or 71V416L10BE8 equivalent, key selection criteria include its 10 ns read cycle time, byte-enable-controlled 16-bit word access, industrial-grade temperature support (–40°C to +85°C), and CABGA-48 package compatibility with space-constrained PCB layouts.
Technical Context
The 71V416L10BE8 implements fully static asynchronous circuitry-no clocks or refresh required-and uses separate high-byte (BHE) and low-byte (BLE) enable inputs to support partial-word writes without bus contention. Its address decoding logic supports concurrent chip select (CS), output enable (OE), and write enable (WE) control for flexible timing modes including CS-, OE-, and byte-enable–controlled reads/writes.
It features LVTTL-compatible bidirectional I/Os with guaranteed VOH ≥ 2.4 V at –4 mA and VOL ≤ 0.4 V at 8 mA, operates across 3.0–3.6 V supply range, and delivers 10 mA max dynamic standby current (ISB1) in full standby mode-critical for low-power embedded memory subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4,194,304 bits (256K × 16 organization) - supports 16-bit parallel data paths without external multiplexing. |
| Access Time (tAA) | 10 ns maximum - enables direct interfacing with 100 MHz microcontrollers and FPGAs without wait states. |
| Supply Voltage | 3.3 V nominal (3.0–3.6 V range) - compatible with modern low-voltage logic families and eliminates level-shifting requirements. |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including motor drives and telecom infrastructure. |
| Standby Current (ISB1) | 10 mA maximum - reduces system-level power consumption during idle cycles in battery-backed or energy-sensitive applications. |
| Package | 48-ball CABGA (9 mm × 9 mm, BE48 footprint) - provides fine-pitch surface-mount reliability and thermal performance for dense PCB layouts. |
| I/O Interface | LVTTL-compatible bidirectional data (I/O0–I/O15) - ensures seamless integration with 3.3 V FPGA I/O banks and ASIC memory controllers. |
Pinout & Package
71V416L10BE8 is packaged in a 48-ball CABGA (BE48), 9 mm × 9 mm, 0.8 mm ball pitch, RoHS-compliant green package. 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; no internal address latching required. |
| CS | Chip Select | Active-low enable controlling device activation; allows multi-chip memory expansion with decode logic. |
| OE | Output Enable | Active-low control for tri-state output drivers; enables bus sharing with other peripherals on shared data lines. |
| WE | Write Enable | Active-low signal initiating write cycles; supports both CS- and WE-controlled write timing modes. |
| BHE / BLE | Byte Enable Inputs | Independent high- and low-byte controls allow 8-bit partial writes without disturbing adjacent byte data. |
| I/O0–I/O15 | Bidirectional Data I/O | 16-bit LVTTL-compatible data path; direction controlled implicitly by WE and CS state, not external direction signals. |
| VDD / VSS | Power / Ground | Dual VDD/VSS pairs (per JEDEC center-pin layout) minimize simultaneous switching noise and improve signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Center Power/Ground Pinout | Reduces ground bounce and supply noise by symmetrically distributing VDD/VSS pins around the die perimeter. |
| Byte-Enable Architecture (BHE/BLE) | Enables selective 8-bit writes to upper or lower half of 16-bit word-eliminates read-modify-write overhead in firmware. |
| 10 ns Read Cycle (tRC) | Supports burst-free, zero-wait-state operation with high-performance microprocessors and DSPs requiring deterministic latency. |
| Low-Power Standby Mode (ISB1 = 10 mA) | Minimizes quiescent power in always-on systems such as industrial PLCs and medical monitoring devices. |
| Single 3.3 V Supply Operation | Removes need for dual-supply regulators or level shifters-simplifies power architecture and reduces BOM cost. |
Applications
| Industrial PLC Memory Buffer | Network Packet Buffer |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-10ZSXI | 256K × 16, 10 ns, 3.3 V, TSOP-44 package only - no CABGA option; higher ISB1 (25 mA). | Lacks 48-ball BGA footprint; less suitable for space-constrained aerospace or portable medical designs. | Prefer when board layout already uses TSOP-44 and thermal constraints permit higher standby current. |
| AS6C4008-10TIN | 256K × 16, 10 ns, 3.3 V, SOJ-44 package; no byte-enable pins - only full-word access supported. | Requires external logic for byte masking; incompatible with partial-write firmware architectures. | Select only if legacy SOJ socket compatibility is mandatory and byte-granular writes are unnecessary. |
Compared with CY62167EV30LL-10ZSXI and AS6C4008-10TIN, the 71V416L10BE8 uniquely combines CABGA-48 packaging, true byte-enable functionality, and 10 mA full-standby current-making it optimal for new industrial and medical designs prioritizing density, power, and write granularity.

FAQ
What is the maximum operating frequency supported by the 71V416L10BE8?
The 71V416L10BE8 does not use a clock and operates asynchronously, so it has no maximum operating frequency specification. Its 10 ns access time (tAA) and 10 ns read cycle time (tRC) define the fastest achievable random-access rate-supporting up to ~100 MHz effective bandwidth in burst-free operation when interfaced with compatible controllers.
Does the 71V416L10BE8 require an external clock or refresh circuitry?
No, the 71V416L10BE8 uses fully static CMOS memory cells and requires neither a clock nor periodic refresh. It retains data indefinitely as long as VDD is applied and remains within specification-making it ideal for systems where deterministic timing and zero-refresh overhead are essential.
Can the 71V416L10BE8 be used with 5 V logic interfaces?
No-the 71V416L10BE8 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. Direct connection to 5 V logic may damage the part or cause unreliable operation; level translation is required for mixed-voltage systems.
What is the function of Pin 28 on the 71V416L10BE8 CABGA package?
Pin 28 on the 71V416L10BE8 (BE48 package) is designated NC (No Connect), but may optionally be tied to VSS per Renesas' datasheet note. This flexibility supports grounding strategies for noise suppression without altering core functionality or pin compatibility.
How does the 71V416L10BE8 handle partial writes to 8-bit subfields?
The 71V416L10BE8 uses dedicated BHE (high-byte enable) and BLE (low-byte enable) inputs to gate write operations to I/O8–I/O15 or I/O0–I/O7 independently. When only one byte enable is active, the other 8 bits remain undisturbed-enabling atomic partial-word updates without read-modify-write sequences.
