Product details
Overview
71V016SA15PHG from Renesas Electronics is a 64K × 16-bit (1 Mbit), 3.3 V high-speed CMOS static RAM with 15 ns access time, LVTTL-compatible I/O, and industrial temperature support (–40°C to +85°C). It features separate upper/lower byte enables, single-chip-select plus output-enable control, and operates fully asynchronously without clocks or refresh. It is used in real-time embedded controllers requiring deterministic low-latency memory access.
For engineers reviewing the 71V016SA15PHG datasheet, 71V016SA15PHG pinout, 71V016SA15PHG application, or 71V016SA15PHG equivalent, key selection criteria include access time consistency across CS/OE/BE control paths, byte-selectable write capability, 3.3 V LVTTL interface compatibility, and TSOP-44 packaging for space-constrained PCB layouts.
Technical Context
The 71V016SA15PHG implements a fully static asynchronous architecture with no clock or refresh circuitry. Its address decoding, sense amplifiers, and bidirectional I/O buffers are all designed for LVTTL voltage thresholds and timing margins at 3.3 V.
It supports three independent write enable modes-full-word, high-byte, and low-byte-via dedicated BHE and BLE inputs, each with guaranteed tBE ≤ 7 ns (max) and tBW ≤ 10 ns (max) at 15 ns speed grade. Output enable (OE) provides sub-7 ns data valid delay and 6 ns high-impedance transition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576-bit total); enables 16-bit parallel data bus interfacing without external multiplexing. |
| Access Time (tAA) | 15 ns max; guarantees deterministic read latency from address assertion to valid data on I/O pins under worst-case industrial conditions. |
| Supply Voltage | 3.15–3.6 V; compatible with standard 3.3 V LVTTL logic rails and tolerant of typical board-level supply ripple. |
| Operating Temperature | –40°C to +85°C; qualified for industrial environments including motor control, factory automation, and transportation electronics. |
| I/O Interface | LVTTL-compatible bidirectional I/O (VIL ≤ 0.8 V, VIH ≥ 2.0 V); ensures direct interoperability with FPGA, MCU, and ASIC I/O banks without level-shifting. |
| Power Consumption | ISB1 = 10 µA max (full standby); ICC = 130 mA max (dynamic operation at fMAX); supports low-power idle states in battery-backed or energy-sensitive systems. |
| Package | 44-pin TSOP Type II (PHG44); JEDEC-standard footprint with 0.8 mm pitch, optimized for automated assembly and thermal dissipation in dense layouts. |
Pinout & Package
44-pin TSOP Type II (PHG44) package, 12.0 × 20.0 mm body, 0.8 mm lead pitch, JEDEC MO-143AC compliant. RoHS-compliant, green (halogen-free) variant available.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus; fully decoded internally to select one of 65,536 memory locations. |
| CS | Chip Select | Active-low global enable; device enters standby (high-Z I/O, ISB1 = 10 µA) when deasserted. |
| OE | Output Enable | Active-low control for output drivers; enables fast read access with tOE ≤ 7 ns (max) and tOHZ ≤ 6 ns (max). |
| WE | Write Enable | Active-low write strobe; initiates write cycle with tWP ≥ 10 ns (min) and tDW ≥ 7 ns (min) timing compliance. |
| BHE | High-Byte Enable | Active-low control for I/O8–I/O15; allows independent 8-bit writes to upper byte without disturbing lower byte. |
| BLE | Low-Byte Enable | Active-low control for I/O0–I/O7; enables selective 8-bit writes to lower byte while preserving upper byte contents. |
| I/O0–I/O15 | Bidirectional Data I/O | 16-bit LVTTL-compatible data bus; direction controlled by WE, CS, BHE, and BLE states per truth table. |
| VDD | Power Supply | +3.3 V supply input; requires local decoupling due to dynamic current peaks up to 130 mA. |
| VSS | Ground | Signal and power ground reference; two dedicated pins (pins 12 & 25) reduce ground bounce in high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Equal access and cycle times | tRC = tAA = 15 ns (max); eliminates timing margin uncertainty between read and write cycles in real-time firmware. |
| Byte-selectable write capability | Dedicated BHE/BLE pins with tBE ≤ 7 ns (max); enables efficient partial-word updates without read-modify-write overhead. |
| Ultra-fast output enable | tOE ≤ 7 ns (max), tOHZ ≤ 6 ns (max); supports tight timing budgets in burst-mode or pipelined memory interfaces. |
| Low-power standby mode | ISB1 = 10 µA (max) at full standby; reduces system quiescent power in sleep or hibernation states. |
| Industrial temperature qualification | –40°C to +85°C operation verified across speed grades; suitable for uncontrolled ambient deployments without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXI | 512K × 16-bit (8 Mbit), 45 ns access, 3.3 V; larger density but slower speed; SOIC-44 package. | Used where memory depth > 1 Mbit is required and latency < 15 ns is not critical (e.g., non-real-time data logging). | Select only if higher capacity outweighs need for sub-15 ns determinism; not drop-in due to different pinout and timing. |
| IS61LV25616AL-10TLI | 256K × 16-bit (4 Mbit), 10 ns access, 3.3 V; faster and denser, but uses 48-pin TSOP-I (not pin-compatible). | Suitable for next-generation designs targeting tighter timing margins and higher throughput, with layout redesign flexibility. | Consider for new designs needing better performance; requires PCB revision due to different pin count, spacing, and signal mapping. |
Compared with CY62167EV30LL-45ZSXI and IS61LV25616AL-10TLI, the 71V016SA15PHG offers optimal balance of 15 ns latency, industrial temperature support, and TSOP-44 footprint - making it ideal for legacy-compatible upgrades and space-constrained industrial controllers where timing predictability is non-negotiable.

FAQ
What is the maximum operating frequency supported by the 71V016SA15PHG?
The 71V016SA15PHG does not use a clock and therefore has no operating frequency specification. Its performance is defined by timing parameters: tRC = 15 ns (max) implies a theoretical maximum sustained cycle rate of ~66.7 MHz, but actual throughput depends on system-level address/data bus handshaking and controller timing margins. The 71V016SA15PHG achieves this with zero refresh overhead and fully static operation.
Does the 71V016SA15PHG support both commercial and industrial temperature ranges?
Yes, the 71V016SA15PHG is specified for industrial temperature operation from –40°C to +85°C. The "PHG" package code denotes TSOP-44, and the absence of an "I" suffix in the full part number (e.g., 71V016SA15PHGI) indicates the commercial-grade version; however, Renesas documentation confirms industrial qualification is available for the 15 ns speed grade in PHG44 packaging, as verified in the Ordering Information table and Absolute Maximum Ratings section.
Can the 71V016SA15PHG be used with 5 V logic interfaces?
No, the 71V016SA15PHG is strictly a 3.3 V LVTTL device. Its VIH minimum is 2.0 V and VIL maximum is 0.8 V, and absolute maximum input voltage is VDD + 0.5 V (≤ 4.1 V). Direct connection to 5 V logic will exceed input voltage ratings and risk permanent damage. Level translation is required for interfacing with 5 V systems.
What is the function of the BHE and BLE pins on the 71V016SA15PHG?
BHE (High-Byte Enable) and BLE (Low-Byte Enable) are active-low inputs that independently control write operations to the upper (I/O8–I/O15) and lower (I/O0–I/O7) data bytes. When only one is asserted, the corresponding 8-bit portion is written while the other remains unchanged - enabling efficient partial-word updates without read-modify-write sequences. This functionality is confirmed in the Truth Table and AC Electrical Characteristics sections of the datasheet.
Is the 71V016SA15PHG pin-compatible with earlier IDT versions like the IDT71V016SA15PHG?
Yes, the 71V016SA15PHG is a Renesas rebranding of the original IDT71V016SA15PHG. Pinout, timing, electrical specifications, and package dimensions are identical. Renesas acquired IDT in 2019 and continued the product under the same ordering nomenclature and datasheet revision history, with no functional or mechanical changes introduced post-acquisition.
