Product details
Overview
71V016SA10PHGI8 from Renesas Electronics is a 64K × 16-bit (1 Mbit), 3.3 V high-speed CMOS static RAM with 10 ns access time, industrial temperature range (–40°C to +85°C), LVTTL-compatible I/O, and byte-enable control. It supports asynchronous read/write operations without clocks or refresh, and is used in real-time embedded controllers, network packet buffers, and FPGA configuration memory.
For engineers reviewing the 71V016SA10PHGI8 datasheet, 71V016SA10PHGI8 pinout, 71V016SA10PHGI8 application, or 71V016SA10PHGI8 equivalent, key selection criteria include tAA ≤ 10 ns, industrial-grade reliability, SOJ-44 package compatibility, byte-select capability, and low-power standby current (ISB1 = 10 mA).
Technical Context
This device implements fully static asynchronous circuitry with no clock or refresh requirement. Its dual-byte enable (BHE/ BLE) pins allow independent 8-bit access to upper and lower data bytes, while OE enables fast output gating (tOE ≤ 5 ns) and CS controls full chip select (tACS ≤ 10 ns).
The 71V016SA10PHGI8 uses high-reliability CMOS technology and operates across VDD = 3.15–3.6 V. All inputs and outputs are LVTTL-compatible, and it supports three distinct write control modes-CS-, WE-, or byte-enable–controlled-with defined timing relationships per AC table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576-bit total); supports word-wide data transfers without external multiplexing. |
| Access Time (tAA) | ≤10 ns at VDD = 3.15–3.6 V, TA = –40°C to +85°C; enables tight timing margins in high-speed bus interfaces. |
| Supply Voltage | 3.15–3.6 V; single-rail operation eliminates need for voltage translation in 3.3 V systems. |
| Standby Current (ISB1) | 10 mA max (static); ensures low power consumption during idle states in battery-backed or energy-sensitive designs. |
| Operating Temperature | –40°C to +85°C; qualified for industrial environments including motor control, telecom infrastructure, and transportation electronics. |
| I/O Interface | LVTTL-compatible bidirectional data (I/O0–I/O15); interoperable with standard 3.3 V logic families without level shifters. |
| Package | 44-pin Plastic SOJ (PBG44); JEDEC-standard footprint compatible with legacy PCB layouts and automated assembly. |
Pinout & Package
71V016SA10PHGI8 is housed in a 44-pin Plastic SOJ (PBG44) package with 300-mil body width and gull-wing leads. The package meets JEDEC MO-118AB standards and supports reflow soldering per IPC/JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus; selects one of 64K memory locations; TTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V). |
| CS | Chip Select | Active-low global enable; places device in active or high-Z standby mode; tACS ≤ 10 ns guarantees fast activation. |
| WE | Write Enable | Active-low write control; initiates write cycle when CS and BHE/ BLE are also asserted; tWP ≥ 7 ns minimum pulse width. |
| OE | Output Enable | Active-low output gate; enables data output without affecting internal state; tOE ≤ 5 ns supports rapid read turnaround. |
| 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 partial-word writes and reduces bus contention in byte-oriented systems. |
| I/O0–I/O15 | Bidirectional Data | 16-bit LVTTL I/O bus; tristated when CS, OE, BHE, or BLE are inactive; VOH ≥ 2.4 V / VOL ≤ 0.4 V at load. |
| VDD | Power Supply | +3.3 V supply pin; requires local decoupling; ICC ≤ 160 mA max under dynamic operation at 10 ns speed grade. |
| VSS | Ground | Reference ground for all signals and power; two dedicated VSS pins reduce ground bounce in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous Static Operation | No clocks or refresh required; simplifies system timing design and eliminates hidden refresh overhead in real-time applications. |
| Byte-Enable Architecture | Independent BHE/ BLE control enables efficient 8-bit microprocessor interfacing and avoids unnecessary full-word writes. |
| Fast Output Enable | tOE ≤ 5 ns allows rapid read-to-read transitions on shared buses, improving throughput in burst-access scenarios. |
| Industrial Temperature Range | Rated for –40°C to +85°C operation; validated for use in uncontrolled environments like factory automation and outdoor telecom nodes. |
| Low Standby Power | ISB1 = 10 mA max (static) enables long-term retention in battery-backed SRAM applications without excessive drain. |
Applications

IC Role / Device Role / Timing Role: Asynchronous static RAM providing deterministic, zero-latency read/write access for deterministic scan-cycle execution. Use Value: 10 ns tAA and industrial temperature rating ensure consistent performance across thermal cycles, eliminating timing violations during PLC scan updates. |
Use Scenario: Holds configuration bitstreams for Xilinx Spartan or Intel Cyclone FPGAs during cold-start initialization in edge gateway devices. IC Role / Device Role / Timing Role: Non-volatile boot memory interface delivering parallel 16-bit configuration words to FPGA configuration port.

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-10ZSXI | 64K × 16-bit, 10 ns, 3.3 V, SOJ-44, but rated –40°C to +85°C only with derated tAA = 12 ns at temperature extremes. | Lower guaranteed speed over full industrial range; suitable where marginal timing margin exists. | Select if Cypress supply chain continuity is prioritized and system timing budget allows 2 ns margin degradation at temperature limits. |
| AS6C1008-10TIN | 128K × 8-bit (1 Mbit), 10 ns, 3.3 V, SOJ-32; lacks byte enables and has narrower 8-bit bus. | Requires external byte steering logic for 16-bit systems; higher density but incompatible pinout and interface. | Choose only for new 8-bit bus designs or when board space constraints favor smaller SOJ-32 footprint and 8-bit data path. |
Compared with CY62167EV30LL-10ZSXI and AS6C1008-10TIN, the 71V016SA10PHGI8 uniquely delivers guaranteed 10 ns access across full industrial temperature range with native 16-bit bus and dual byte enables-enabling direct integration into legacy 16-bit microcontroller and FPGA platforms without glue logic or timing compromises.

FAQ
What is the maximum guaranteed access time for 71V016SA10PHGI8 across its full operating temperature range?
The 71V016SA10PHGI8 guarantees tAA ≤ 10 ns across –40°C to +85°C at VDD = 3.15–3.6 V, as specified in Table 10 of the Renesas datasheet. This value is production-tested and applies to all units shipped under this orderable part number, not just characterization samples.
Does 71V016SA10PHGI8 require external refresh circuitry or clock signals?
No, the 71V016SA10PHGI8 is a fully static RAM and requires no clocks, timers, or refresh cycles. Its internal latches retain data indefinitely as long as VDD remains within specification and CS is held high during standby-making it ideal for deterministic real-time systems.
Can 71V016SA10PHGI8 be used with 5 V logic interfaces?
No, 71V016SA10PHGI8 is strictly a 3.3 V LVTTL device. Its absolute maximum input voltage is VDD + 0.5 V (≤ 4.1 V), and VIH threshold is defined relative to VDD (≥ 2.0 V). Direct connection to 5 V logic risks damage and violates DC electrical specifications.
What is the function of the NC pins on the 71V016SA10PHGI8 SOJ-44 package?
The 71V016SA10PHGI8 SOJ-44 package has four NC (No Connect) pins: Pin 6 (A12 side), Pin 22 (A15 side), Pin 32 (VDD side), and Pin 44 (A11 side). These pins are not bonded internally and must remain unconnected-no pull-up, pull-down, or routing is permitted per Renesas design guidelines.
How does the byte-enable functionality of 71V016SA10PHGI8 improve system-level efficiency?
The BHE and BLE pins on 71V016SA10PHGI8 allow independent 8-bit writes to upper (I/O8–I/O15) or lower (I/O0–I/O7) bytes without reading-modify-write sequences. This reduces bus traffic, lowers power consumption, and prevents unintended corruption of adjacent data-critical in multi-master or interrupt-driven systems.
