Product details
Overview
71V416L15BE from Renesas is a 4-Mbit (256K × 16) low-power, 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 serves as a non-refreshing, fully static asynchronous memory buffer in embedded controllers, network interface cards, and industrial PLCs requiring deterministic timing.
For engineers reviewing the 71V416L15BE datasheet, 71V416L15BE pinout, 71V416L15BE application, or 71V416L15BE equivalent, key selection criteria include its 15 ns read cycle time, byte-enable-controlled 16-bit data access, industrial-grade temperature support (–40°C to +85°C), and 48-ball CABGA (BE48) package compatibility with space-constrained PCB layouts.
Technical Context
The 71V416L15BE implements fully static asynchronous logic with no clocks or refresh required. Its architecture includes independent high- and low-byte enable (BHE/BLE), output enable (OE), chip select (CS), and write enable (WE) controls-enabling word, high-byte, or low-byte read/write operations without external gating.
It uses LVTTL-compatible bidirectional I/O buffers with guaranteed VOH ≥ 2.4 V at –4 mA and VOL ≤ 0.4 V at 8 mA under min VDD (3.0 V). The device supports three distinct package variants-SOJ, TSOP II, and CABGA-but the 71V416L15BE specifically maps to the 48-ball, 9 mm × 9 mm BE48/BEG48 CABGA footprint with NC pins at positions A1, D1, G1, and H1 per Renesas' pin table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4,194,304 bits (256K × 16), enabling 32 KB of fast, deterministic storage without refresh overhead. |
| Access Time (tAA) | 15 ns max - defines minimum address-to-valid-data delay for synchronous bus interfacing. |
| Read Cycle Time (tRC) | 15 ns max - sets shortest interval between successive read operations on same address range. |
| Supply Voltage | 3.0 V to 3.6 V - compatible with standard 3.3 V logic rails; no level-shifting needed for LVTTL hosts. |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including motor drives and factory automation. |
| Standby Current (ISB1) | 10 µA max - ultra-low static power draw during CS-high sleep mode, critical for battery-backed systems. |
| I/O Capacitance | 7 pF max (CIN), 7 pF max (CI/O) - ensures signal integrity and timing margin in high-speed parallel bus designs. |
Pinout & Package
71V416L15BE is packaged in a 48-ball grid array (CABGA), 9 mm × 9 mm, BE48/BEG48 footprint. Pin mapping follows JEDEC-compliant ball assignment with VDD/VSS distributed across center rows to minimize simultaneous switching noise.
| 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 global enable; places device in standby (high-Z I/O) when deasserted. |
| OE | Output Enable | Active-low control for output drivers; enables read data only when CS and OE are both low. |
| WE | Write Enable | Active-low write strobe; latches data on I/O0–I/O15 when CS, WE, and BHE/BLE are asserted. |
| BHE / BLE | Byte Enable | Independent active-low controls for upper (I/O8–I/O15) and lower (I/O0–I/O7) data bytes. |
| I/O0–I/O15 | Bidirectional Data | LVTTL-compatible 16-bit data bus; direction controlled by WE state and byte enables. |
| VDD | Power Supply | 3.3 V core supply; multiple balls (B2, D2, E2, F2, G2, H2) reduce IR drop and improve decoupling. |
| VSS | Ground | System ground reference; distributed across center columns (A3, A4, A5, A6, B3, B4, etc.) for low-inductance return path. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Center Power/Ground Pinout | Reduces simultaneous switching noise by interleaving VDD/VSS near signal balls-critical for stable 15 ns timing margins. |
| Independent Byte Enables (BHE/BLE) | Enables partial-word writes without read-modify-write cycles, reducing bus contention and CPU overhead in 8-bit peripheral interfaces. |
| Low Standby Current (ISB1 = 10 µA) | Extends battery life in always-on industrial sensors and retains data integrity during brownout conditions. |
| Single 3.3 V Supply Operation | Eliminates need for dual-voltage regulators or level shifters-simplifies power delivery in compact embedded systems. |
| 15 ns Access + 15 ns Cycle Time | Matches timing budgets of legacy PCI, ISA, and microcontroller parallel buses without wait-state insertion. |

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-15ZSXI | 256K × 16, 15 ns, 3.3 V, but uses 44-pin TSOP-II (not CABGA); higher ISB1 (25 µA). | Requires PCB redesign for SOJ/TSOP footprint; less suitable for dense BGA-based automotive modules. | Preferred where legacy board reuse or cost-sensitive TSOP assembly is prioritized over space savings. |
| AS6C4008-15TIN | 256K × 16, 15 ns, 3.3 V, 44-pin TSOP-II; lacks BHE/BLE-byte writes require external logic. | Not pin-compatible; requires additional glue logic for byte-select functionality in existing 71V416L15BE designs. | Consider only if BHE/BLE is unused and TSOP-II packaging aligns with manufacturing infrastructure. |
Compared with CY62167EV30LL-15ZSXI and AS6C4008-15TIN, the 71V416L15BE uniquely combines CABGA packaging, true independent byte enables, and 10 µA standby current-making it optimal for new industrial and automotive designs where layout density, power efficiency, and partial-word write capability are jointly critical.

FAQ
What is the maximum operating temperature range for the 71V416L15BE?
The 71V416L15BE is rated for industrial operation from –40°C to +85°C. This specification is validated per Renesas' DC and AC electrical characteristics tables and applies to all package variants-including the BE48 CABGA used in the 71V416L15BE orderable part. No derating is required within this range.
Does the 71V416L15BE support true independent byte writes without external logic?
Yes. The 71V416L15BE provides dedicated BHE (high-byte enable) and BLE (low-byte enable) inputs that directly control I/O8–I/O15 and I/O0–I/O7, respectively. When one byte enable is low and the other high, only the selected 8-bit subset is written-no external gates or latches are needed.
What is the standby current consumption of the 71V416L15BE in full static mode?
In full standby mode (CS = VIH, f = 0), the 71V416L15BE draws ≤10 µA typical and ≤10 µA maximum ISB1 current. This value is guaranteed across voltage (3.0–3.6 V) and temperature (–40°C to +85°C) per Renesas' DC Electrical Characteristics table.
Is the 71V416L15BE pin-compatible with earlier IDT-branded versions?
Yes. The 71V416L15BE maintains identical pinout, timing, and electrical specifications as the original IDT71V416L15BE. Renesas acquired IDT's memory portfolio and retained full functional and mechanical compatibility-including BE48 ball map, JEDEC pin assignments, and AC/DC parameter limits.
What package type does the 71V416L15BE use, and are there lead-free options?
The 71V416L15BE uses a 48-ball CABGA (BE48/BEG48), 9 mm × 9 mm, RoHS-compliant and lead-free. "G" suffix variants (e.g., 71V416L15BEG) denote green (halogen-free) construction, confirmed in Renesas' Ordering Information table.
