Product details
Overview
71V016SA15PHG8 from Renesas Electronics is a 64K × 16-bit, 1 Mbit high-speed CMOS static RAM operating at 3.3 V with 15 ns read/write cycle time, industrial temperature range (–40°C to +85°C), and LVTTL-compatible bidirectional I/Os. It features separate byte enable (BHE/BLE), output enable (OE), and chip select (CS) for flexible memory access in embedded controllers and data acquisition systems.
For engineers reviewing the 71V016SA15PHG8 datasheet, 71V016SA15PHG8 pinout, 71V016SA15PHG8 application, or 71V016SA15PHG8 equivalent, key selection criteria include access timing (tAA = 15 ns), standby current (ISB = 35 mA), byte-select capability, 44-pin TSOP-II package compatibility, and industrial-grade reliability for real-time control subsystems.
Technical Context
The 71V016SA15PHG8 implements fully static asynchronous logic with no clocks or refresh required. Its architecture supports independent high-byte (I/O8–I/O15) and low-byte (I/O0–I/O7) writes via BHE and BLE, enabling efficient 8-bit data transfers within 16-bit bus systems.
Timing is controlled by three independent enables: CS governs device selection, OE controls output drivers, and WE determines write initiation. All inputs meet LVTTL voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and outputs drive ±4 mA/±8 mA loads while maintaining VOL ≤ 0.4 V and VOH ≥ 2.4 V under min VDD.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXI | 512K × 16-bit (8 Mbit), 45 ns access, 3.3 V, SOIC-44; higher density but slower speed. | Suitable for non-real-time buffering where latency <20 ns is not critical-e.g., firmware update staging or configuration storage. | Select when memory capacity outweighs timing constraints and board space allows larger SOIC footprint. |
| AS6C1008-15TIN | 128K × 8-bit (1 Mbit), 15 ns, 3.3 V, TSOP-32; narrower 8-bit bus, same speed grade. | Requires two devices for 16-bit word width-increases PCB area and routing complexity versus single 71V016SA15PHG8. | Choose only if existing design uses 8-bit data paths or requires dual-rank expansion without bus widening. |
Compared with CY62167EV30LL-45ZSXI and AS6C1008-15TIN, the 71V016SA15PHG8 uniquely delivers 16-bit bus width, 15 ns timing, and industrial temperature rating in a single 44-pin TSOP package-making it optimal for space-constrained, latency-sensitive embedded controllers requiring byte-select granularity.

FAQ
What is the maximum clock frequency supported by the 71V016SA15PHG8?
The 71V016SA15PHG8 is an asynchronous static RAM and does not use a clock signal. Its performance is defined by timing parameters-not frequency. With a 15 ns read cycle time (tRC), it supports up to 66.7 million random accesses per second in burst mode. System-level throughput depends on bus protocol, controller timing margins, and whether byte or full-word operations are used. The 71V016SA15PHG8 achieves this without clocks or refresh cycles, making it ideal for deterministic real-time applications.
Does the 71V016SA15PHG8 support both commercial and industrial temperature ranges?
Yes, the 71V016SA15PHG8 is specified for the industrial temperature range of –40°C to +85°C, as confirmed in the Renesas datasheet's Ordering Information table and Absolute Maximum Ratings section. The 'I' suffix in the package code (PHG44-I) denotes industrial qualification. Unlike some speed grades limited to commercial use, the 15 ns variant explicitly supports industrial operation-verified by characterization across the full range and validated for use in harsh-environment applications like motor drives and outdoor base stations.
Can the 71V016SA15PHG8 be used with 5 V logic interfaces?
No, the 71V016SA15PHG8 is strictly a 3.3 V LVTTL device and is not 5 V tolerant. Its absolute maximum input voltage is VDD + 0.5 V (≤ 4.1 V), and VIH minimum is 2.0 V-compatible only with 3.3 V logic families. Connecting it directly to 5 V buses risks permanent damage due to overvoltage stress on input structures. If interfacing with 5 V controllers, level-shifting circuitry (e.g., TXB0108 or discrete MOSFET translators) must be used. The 71V016SA15PHG8 itself provides no internal voltage translation.
How does byte enable (BHE/BLE) function during a write operation on the 71V016SA15PHG8?
During a write, asserting BHE low enables writing to I/O8–I/O15 (high byte), while asserting BLE low enables writing to I/O0–I/O7 (low byte). Both can be asserted simultaneously for full 16-bit writes. When only one is active, the unselected byte retains its prior value-no read-modify-write is needed. This behavior is defined in the Truth Table (Table 02) and verified by AC timing waveforms for BHE/BLE-controlled write cycles. The 71V016SA15PHG8 uses this feature to reduce bus traffic and simplify software drivers in mixed-data-width systems.
Is the 71V016SA15PHG8 pin-compatible with other speed grades in the same package?
Yes, all 71V016SA variants-including 10 ns, 12 ns, 15 ns, and 20 ns-in the PHG44 (44-pin TSOP) package share identical pinouts, electrical interfaces, and functional behavior. The only differences are timing specifications and corresponding speed binning. A 71V016SA15PHG8 can replace a 71V016SA12PHG8 on the same PCB without layout changes, though timing-critical designs must verify setup/hold margins against the slower 15 ns spec. This interchangeability simplifies inventory management and design reuse across performance tiers.
