Product details
Overview
71V016SA20PHGI8 from Renesas Electronics is a 3.3V, 1-Megabit (64K × 16) high-speed CMOS static RAM with 20 ns read/write cycle time, industrial temperature range (–40°C to +85°C), and LVTTL-compatible bidirectional I/O. It features separate upper/lower byte enables, single-chip-select plus output-enable control, and operates without clocks or refresh-used in real-time embedded controllers and legacy bus-based systems requiring deterministic memory access.
For engineers reviewing the 71V016SA20PHGI8 datasheet, 71V016SA20PHGI8 pinout, 71V016SA20PHGI8 application, or 71V016SA20PHGI8 equivalent, key selection criteria include industrial-grade timing consistency, 3.3V-only supply compatibility, byte-select capability for 8-bit subsystems, and TSOP-44 package suitability for space-constrained PCB layouts with manual or wave-solder assembly.
Technical Context
The 71V016SA20PHGI8 implements fully static asynchronous architecture with no internal clocks or refresh circuitry. Its address decoding, sense amplifiers, and write drivers are all CMOS-based, enabling stable operation across the full industrial temperature range while maintaining guaranteed 20 ns cycle time under worst-case VDD (3.15 V) and load conditions.
It supports three independent enable domains: chip select (CS) for device-level activation, output enable (OE) for tri-state control of I/O pins, and dual byte enables (BHE/BLE) for selective 8-bit access-allowing efficient integration into 16-bit data buses where partial writes or reads are required without external logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1,048,576-bit (64K × 16) - provides 128 KB of word-addressable storage for firmware buffers or real-time data tables |
| Access Time | 20 ns max - ensures predictable latency for deterministic microcontroller or DSP memory fetches |
| Supply Voltage | 3.15 V to 3.6 V - compatible with standard 3.3V logic rails; no level-shifting needed |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including factory automation and transportation electronics |
| I/O Interface | LVTTL-compatible - directly interfaces with 3.3V microcontrollers, FPGAs, and ASICs without voltage translation |
| Power Consumption | 120 mA dynamic (ICC), 30 mA standby (ISB) - enables low-power sleep modes in battery-backed or energy-sensitive systems |
| Package | 44-pin TSOP Type II (PHG44) - surface-mount, JEDEC-standard footprint supporting automated placement and reflow |
Pinout & Package
71V016SA20PHGI8 is housed in a 44-pin Plastic TSOP Type II (PHG44) package, 10.16 mm × 18.42 mm body size, 0.8 mm pitch, with gull-wing leads suitable for standard SMT assembly and thermal cycling reliability in industrial applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus accepting 0–65,535 word locations; fully static-no setup/hold timing constraints on address stability during CS active |
| CS | Chip Select | Active-low global enable; places device in standby (high-Z I/O) when deasserted, reducing ICC to ISB levels |
| WE | Write Enable | Active-low control for write cycles; combined with CS and BHE/BLE determines byte/word write mode per truth table |
| OE | Output Enable | Active-low control for output drivers; allows read data to appear on I/O pins independently of CS/WE state |
| BHE / BLE | Byte Enable Inputs | Active-low controls for high-byte (I/O8–I/O15) and low-byte (I/O0–I/O7); enable partial writes without external gating logic |
| I/O0–I/O15 | Bidirectional Data Bus | 16-bit LVTTL-compliant I/O; automatically switches direction based on WE and OE states per functional block diagram |
| VDD / VSS | Power / Ground | Single 3.3V supply pair; decoupling required within 10 mm of pins per JEDEC TSOP layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Equal Access & Cycle Times | 20 ns tRC = tAA = tACS - eliminates timing margin uncertainty between read and write paths in synchronous bus designs |
| Byte-Enable Architecture | Dedicated BHE/BLE pins - enables 8-bit peripheral interfacing on 16-bit buses without glue logic or data masking overhead |
| Low-Power Standby | 30 mA ISB at VDD max - reduces system power by >75% vs. active mode, critical for thermally constrained enclosures |
| Industrial Temperature Qualification | –40°C to +85°C operation - validated across full range for automotive engine control modules and rail signaling hardware |
| No Refresh Required | Fully static CMOS design - removes DRAM controller complexity and eliminates periodic memory refresh interrupts |

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-20ZSXI | 48-pin TSOP-II, 20 ns, 64K × 16, same VDD range but higher ISB (45 mA) | Requires PCB footprint change; lacks industrial temp option in 20 ns grade | Prefer when higher density packaging is acceptable and thermal budget allows extra standby current |
| AS6C1008-20TIN | 44-pin TSOP-II, 20 ns, 128K × 8, 3.3V, industrial temp, but byte-width mismatch | Needs data bus remapping; requires external byte-swapping logic for 16-bit interface | Consider only if system architecture permits 8-bit data path redesign and additional logic gates |
Compared with CY62167EV30LL-20ZSXI and AS6C1008-20TIN, the 71V016SA20PHGI8 offers exact TSOP-44 footprint compatibility, lowest industrial-grade standby current (30 mA), and native 16-bit organization-making it optimal for drop-in replacements and thermally constrained 16-bit bus systems without layout changes.

FAQ
What is the maximum guaranteed access time for the 71V016SA20PHGI8?
The 71V016SA20PHGI8 has a maximum guaranteed address access time (tAA) of 20 ns across the full industrial temperature range (–40°C to +85°C) and supply voltage range (3.15 V to 3.6 V), as specified in the AC Electrical Characteristics table under the 71V016SA20 speed grade. This value is production-tested and applies to all valid input voltage and loading conditions defined in the datasheet.
Does the 71V016SA20PHGI8 require a refresh circuit or clock signal?
No, the 71V016SA20PHGI8 is a fully static CMOS SRAM and requires no refresh circuitry or clock signal. Its asynchronous operation relies solely on address, control (CS/WE/OE/BHE/BLE), and data signals-eliminating timing dependencies associated with DRAM and simplifying integration into microcontroller- or FPGA-based systems.
Can the 71V016SA20PHGI8 be used in a 16-bit data bus configuration with byte-level writes?
Yes, the 71V016SA20PHGI8 supports true 16-bit operation with independent high-byte (I/O8–I/O15) and low-byte (I/O0–I/O7) writes via dedicated BHE and BLE pins. When one byte enable is asserted low and the other high, only the corresponding 8-bit segment is written-enabling efficient partial updates without external data masking logic.
What package type and lead count does the 71V016SA20PHGI8 use?
The 71V016SA20PHGI8 uses a 44-pin Plastic TSOP Type II (PHG44) package, compliant with JEDEC MO-142AB. It features gull-wing leads, 0.8 mm pitch, and a 10.16 mm × 18.42 mm body size-designed for standard SMT reflow processes and compatible with automated optical inspection (AOI) and X-ray void detection.
Is the 71V016SA20PHGI8 qualified for industrial temperature operation?
Yes, the 71V016SA20PHGI8 is explicitly qualified for industrial temperature operation from –40°C to +85°C, as confirmed in the Ordering Information table (suffix "I") and the Absolute Maximum Ratings section. This qualification covers all electrical parameters-including tRC, tAA, ICC, and ISB-under worst-case voltage and thermal conditions.
