Product details
Overview
71V416S15BEGI from Renesas Electronics is a 4-Mbit (256K × 16) high-speed CMOS static RAM with 15 ns access time, single 3.3 V supply operation, LVTTL-compatible I/O, and JEDEC-standard center power/ground pinout for noise reduction. It supports byte-wide and word-wide read/write operations in industrial temperature range (–40°C to +85°C) and is used in real-time embedded controllers requiring deterministic memory access.
For engineers reviewing the 71V416S15BEGI datasheet, 71V416S15BEGI pinout, 71V416S15BEGI application, or 71V416S15BEGI equivalent, key selection criteria include industrial-grade timing consistency, low-Z output enable response (≤7 ns), byte-enable control granularity, and compatibility with legacy 44-pin SOJ/TSOP or 48-ball BGA footprints.
Technical Context
The 71V416S15BEGI implements fully static asynchronous logic with no clocks or refresh required. Its architecture includes independent high- and low-byte enable (BHE/BLE), dual-level chip select (CS) and output enable (OE) control, and bidirectional LVTTL I/O buffers supporting 16-bit data width.
Timing is defined by three independent access paths: address-to-output (tAA = 15 ns), chip-select-to-output (tACS = 15 ns), and output-enable-to-output (tOE = 7 ns). Standby current is specified at 40 mA (ISB) and 10 mA (ISB1) under industrial conditions, enabling low-power hold modes without data loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
71V416S15BEGI is packaged in a 48-ball fine-pitch BGA (BEG48) with 0.8 mm ball pitch and 9 mm × 9 mm body size. The package features perimeter I/O ball placement and internal power/ground distribution optimized for signal integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word addressing; no address multiplexing required |
| CS | Chip Select | Active-low enable controlling device activation; supports hierarchical memory decoding |
| OE | Output Enable | Active-low control for tri-state output drivers; enables bus sharing with ≤7 ns disable delay |
| WE | Write Enable | Active-low write strobe; initiates write cycles when CS and byte enables are asserted |
| BHE / BLE | Byte Enable | Independent high- and low-byte controls allow 8-bit partial writes without disturbing adjacent bytes |
| I/O0–I/O15 | Bidirectional Data | 16-bit LVTTL I/O bus; direction controlled implicitly by WE/CS/OE states per cycle |
| VDD | Power Supply | Single 3.3 V supply input; two dedicated balls (pins E4, E5) reduce IR drop and noise coupling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXI | 512K × 16, 45 ns access, 3.3 V, TSOP-44 - larger density but slower timing | Suitable for non-real-time buffering where latency >40 ns is acceptable | Select when higher capacity outweighs speed; verify PCB pad compatibility with TSOP footprint |
| AS6C4008-15TIN | 256K × 16, 15 ns access, 3.3 V, TSOP-44 - identical timing but different pinout and no BGA option | Drop-in replacement only in TSOP-44 designs; not compatible with BEG48 layout | Choose for cost-sensitive industrial boards using SOJ/TSOP; confirm OE/WE timing alignment matches |
Compared with CY62167EV30LL-45ZSXI and AS6C4008-15TIN, the 71V416S15BEGI uniquely delivers industrial-grade 15 ns performance in a space-saving 48-ball BGA while maintaining JEDEC-compliant pinout for noise-sensitive applications - making it optimal for new designs prioritizing timing determinism and board area efficiency.

FAQ
What is the operating temperature range for the 71V416S15BEGI?
The 71V416S15BEGI is rated for industrial operation from –40°C to +85°C. This range is validated per Renesas' qualification standards and supports deployment in harsh environments such as factory floors, vehicle cabins, and outdoor infrastructure equipment without derating.
Does the 71V416S15BEGI require a refresh circuit?
No, the 71V416S15BEGI is a fully static RAM and requires no refresh circuitry. Its asynchronous design uses only address, control, and data signals - eliminating clock dependencies and simplifying integration into microcontroller- or FPGA-based systems.
Can the 71V416S15BEGI be used with 5 V logic interfaces?
No, the 71V416S15BEGI 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-shifting is mandatory.
What is the meaning of "BEGI" in the part number 71V416S15BEGI?
In 71V416S15BEGI, "BE" denotes 48-ball BGA package, "G" indicates green (lead-free/RoHS-compliant) construction, and "I" specifies industrial temperature grade (–40°C to +85°C). The "S" identifies the standard power variant, and "15" is the 15 ns speed grade.
How does the byte-enable functionality work on the 71V416S15BEGI?
The 71V416S15BEGI uses separate BHE (high byte enable) and BLE (low byte enable) inputs to control 8-bit write granularity. When only BHE is active, I/O8–I/O15 are written; when only BLE is active, I/O0–I/O7 are written - enabling efficient partial updates without full-word reads.
