Product details
Overview
71V416L15PHG from Renesas Electronics is a 4-Mbit (256K × 16) low-power, high-speed CMOS static RAM with 15 ns access time, single 3.3 V supply operation, 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 designed for embedded systems requiring deterministic asynchronous memory access without refresh.
For engineers reviewing the 71V416L15PHG datasheet, 71V416L15PHG pinout, 71V416L15PHG application, or 71V416L15PHG equivalent, key selection criteria include industrial temperature support (–40°C to +85°C), LVTTL-compatible I/O, 44-pin TSOP Type II package compatibility, and low standby current (40 mA max at 3.3 V).
Technical Context
The 71V416L15PHG implements fully static asynchronous circuitry-no clocks or refresh required-and uses dual-byte enable (BHE/BLE) logic to support independent high- and low-byte access. Its address decoding path delivers guaranteed tAA ≤ 15 ns and tACS ≤ 15 ns across industrial temperature range.
Input/output buffers are LVTTL-compatible with VIH(min) = 2.0 V and VIL(max) = 0.8 V at VDD = 3.0–3.6 V; output drivers provide VOH ≥ 2.4 V (IOH = –4 mA) and VOL ≤ 0.4 V (IOL = 8 mA), ensuring robust signal integrity in mixed-voltage 3.3 V systems.
Key Specifications

FAQ
What is the operating temperature range for the 71V416L15PHG?
The 71V416L15PHG is rated for industrial temperature operation from –40°C to +85°C. This specification is production-tested and guaranteed per Renesas' industrial qualification standards, making it suitable for deployment in factory automation controllers, outdoor kiosks, and under-hood automotive modules where ambient extremes are expected. The 71V416L15PHG does not require derating or thermal monitoring within this range.
Does the 71V416L15PHG require a clock or refresh signal?
No, the 71V416L15PHG uses fully static CMOS circuitry and requires no clock, refresh, or periodic access to retain data. Once written, data remains valid indefinitely as long as VDD is maintained within 3.0–3.6 V and ambient temperature stays within the industrial range. This eliminates timing-critical refresh overhead and simplifies system-level design for the 71V416L15PHG.
What package type is used for the 71V416L15PHG?
The 71V416L15PHG is supplied in a 44-pin, 400-mil plastic TSOP Type II package (package code PHG44). It features JEDEC-standard pinout with center-placed VDD and VSS pins to minimize noise coupling. This surface-mount package supports standard reflow profiles and is compatible with automated PCB assembly processes used for the 71V416L15PHG.
Can the 71V416L15PHG perform byte-wide writes?
Yes, the 71V416L15PHG supports independent high-byte (BHE) and low-byte (BLE) write enables. When only BHE is asserted, I/O8–I/O15 are written while I/O0–I/O7 remain unchanged; conversely, asserting only BLE writes I/O0–I/O7. This eliminates need for external byte masking logic and reduces firmware complexity in systems using the 71V416L15PHG.
Is the 71V416L15PHG RoHS compliant and lead-free?
Yes, the 71V416L15PHG is RoHS compliant and lead-free, meeting EU Directive 2011/65/EU and subsequent amendments. The "G" suffix in the part number explicitly denotes green (halogen-free, lead-free) construction. Renesas certifies full compliance for the 71V416L15PHG, including material declarations and process controls verified through third-party testing.
