Product details
Overview
71V416S15PHG8 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 via independent BHE/BLE controls and is used in embedded controllers, networking buffers, and industrial PLC memory expansion.
For engineers reviewing the 71V416S15PHG8 datasheet, 71V416S15PHG8 pinout, 71V416S15PHG8 application, or 71V416S15PHG8 equivalent, key selection criteria include 15 ns read cycle time, TSOP Type II 44-pin package compatibility, 3.3 V LVTTL interface timing, and industrial-grade temperature support (–40°C to +85°C).
Technical Context
The 71V416S15PHG8 implements fully static asynchronous architecture-no clocks or refresh required-and uses dual-byte enable (BHE/BLE) to support 8-bit or 16-bit data transfers without external logic. Its address decoding is internal, with A0–A17 inputs selecting one of 262,144 words.
Operation relies on three independent control signals: CS enables device selection, OE governs output buffer state (with 7 ns tOHZ), and WE determines write direction; all timing parameters-including tAA (15 ns), tRC (15 ns), and tOE (7 ns)-are guaranteed across commercial and industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
71V416S15PHG8 is supplied in a 44-pin, 400-mil TSOP Type II package (PHG44), compliant with JEDEC MO-141BA. Pin layout follows center-power/ground configuration (VDD/VSS at pins 12/11 and 33/32) 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 enable; device enters standby (ISB1 = 20 mA) when high |
| OE | Output Enable | Active-low control of output drivers; tOHZ = 7 ns ensures fast bus release |
| WE | Write Enable | Active-low signal initiating write cycles; tWP = 10 ns minimum pulse width |
| BHE / BLE | Byte Enable | Independent high/low byte gating - enables 8-bit peripheral interfacing without glue logic |
| I/O0–I/O15 | Bidirectional Data | 16-bit LVTTL I/O bus; high-impedance state when CS, OE, or WE inactive |
| VDD / VSS | Power / Ground | Dual VDD (pins 12, 33) and VSS (pins 11, 32) reduce IR drop and ground bounce |
Key Features

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 | 4-Mbit (256K × 16), 45 ns access, 3.3 V, SOIC-44 package | Slower timing invalidates use in 15 ns-critical control loops; larger package footprint | Select only if system timing budget allows ≥45 ns latency and board layout accommodates SOIC instead of TSOP. |
| AS6C4008-15TIN | 4-Mbit (256K × 16), 15 ns access, 3.3 V, TSOP-44, but rated only for commercial temp (0°C to +70°C) | Lacks industrial temperature qualification; unsuitable for field-deployed equipment operating beyond 70°C | Acceptable for lab/test fixtures or indoor consumer devices; reject for outdoor or factory-floor deployments. |
Compared with CY62167EV30LL-45ZSXI and AS6C4008-15TIN, the 71V416S15PHG8 uniquely combines 15 ns speed, industrial temperature range, TSOP-44 footprint, and JEDEC noise-optimized pinout-making it the sole option meeting all four constraints simultaneously in harsh-environment embedded designs.

FAQ
What is the maximum clock frequency supported by the 71V416S15PHG8?
The 71V416S15PHG8 is a fully static asynchronous SRAM and does not use a clock signal. Its performance is defined by timing parameters such as tRC (15 ns read cycle time), enabling effective operation up to 66.7 MHz in burst-read scenarios. System timing must satisfy setup/hold requirements for CS, OE, WE, and address signals-not a clock frequency.
Does the 71V416S15PHG8 require refresh circuitry?
No, the 71V416S15PHG8 is a static RAM and requires no refresh cycles. Its fully static CMOS design retains data indefinitely as long as power is applied and CS remains active or in standby mode. This eliminates refresh overhead and timing complexity found in DRAM-based systems.
Can the 71V416S15PHG8 operate with 2.5 V or 5 V supplies?
No, the 71V416S15PHG8 is specified exclusively for 3.3 V ±10% operation (3.0 V to 3.6 V). Applying 2.5 V will result in undefined behavior or failure to meet AC timing; 5 V will exceed absolute maximum ratings and risk permanent damage. External level shifters are required for interfacing with 2.5 V or 5 V systems.
What is the function of the BHE and BLE pins on the 71V416S15PHG8?
BHE (Byte High Enable) and BLE (Byte Low Enable) are active-low control inputs that independently gate the upper (I/O8–I/O15) and lower (I/O0–I/O7) data bytes. When only one is asserted, the 71V416S15PHG8 performs an 8-bit write; when both are active, it executes a full 16-bit word operation-reducing need for external byte-mask logic.
Is the 71V416S15PHG8 RoHS compliant and halogen-free?
Yes, the 71V416S15PHG8 is a green-part variant (indicated by the 'G' suffix in the part number) and complies with RoHS Directive 2011/65/EU and JEDEC JS709E halogen-free standards. Lead-free soldering compatibility is confirmed per J-STD-020 moisture sensitivity level 3 (MSL-3) for the PHG44 TSOP package.
