Product details
Overview
71016S20PHGI8 from Renesas Electronics is a 64K × 16-bit (1 Mbit) high-speed CMOS static RAM with 20 ns access time, industrial temperature range (–40°C to +85°C), single 5V supply operation, and TTL-compatible bidirectional I/O. It features separate byte enable (BHE/BLE), chip select (CS), output enable (OE), and write enable (WE) for flexible memory interfacing in embedded controllers and data acquisition systems.
For engineers reviewing the 71016S20PHGI8 datasheet, 71016S20PHGI8 pinout, 71016S20PHGI8 application, or 71016S20PHGI8 equivalent, key selection criteria include industrial-grade timing consistency, low standby current (45 mA max), 44-pin TSOP-II package compatibility, and byte-selectable read/write capability without external logic.
Technical Context
The 71016S20PHGI8 implements fully static asynchronous architecture-no clocks or refresh required-and uses high-reliability CMOS process technology. Its dual-byte enable (BHE/BLE) allows independent access to upper and lower 8-bit data lanes, enabling efficient 8-bit microprocessor bus interfacing while maintaining full 16-bit word capability.
Timing is controlled via three independent enable paths: CS-controlled, OE-controlled, and BHE/BLE-controlled read cycles, each with defined setup/hold and transition delays (e.g., tOE ≤ 10 ns, tCLZ ≤ 5 ns). Write operations support WE- or CS-synchronized timing modes, with tWP ≥ 12 ns minimum pulse width and tDW ≥ 10 ns data valid window.

FAQ
What is the maximum operating temperature range for the 71016S20PHGI8?
The 71016S20PHGI8 is rated for industrial temperature operation from –40°C to +85°C. This range is fully specified and tested per AC/DC electrical characteristics in the Renesas datasheet revision dated June 2, 2020. The 71016S20PHGI8 maintains its 20 ns access time and 45 mA standby current guarantee across this entire range, making it suitable for deployment in harsh environmental conditions such as factory floors or outdoor test equipment where thermal stability is critical. No derating is required within these limits.
Does the 71016S20PHGI8 require a refresh circuit or clock signal?
No, the 71016S20PHGI8 is a fully static RAM and requires neither a refresh circuit nor a clock signal. Its internal circuitry operates asynchronously using only address, control (CS/OE/WE/BHE/BLE), and data signals. This eliminates timing dependencies on system clocks, simplifies PCB layout by removing clock routing, and removes risk of data loss during power-supply transients that might disrupt clock generation. The 71016S20PHGI8 retains data indefinitely as long as VCC remains within 4.5–5.5 V and temperature stays within specification.
Can the 71016S20PHGI8 be used with a 3.3 V microcontroller interface?
The 71016S20PHGI8 is a 5 V-only device with TTL-compatible I/O thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V), so direct connection to a 3.3 V microcontroller is not recommended without level translation. While its inputs may recognize 3.3 V as logic HIGH, output VOH (≥2.4 V) falls below typical 3.3 V logic HIGH thresholds (≥2.7 V), risking unreliable reads. For mixed-voltage systems, use discrete level shifters or bus switches. The 71016S20PHGI8 itself does not support dual-supply or voltage-tolerant I/O-its design assumes a 5 V system environment.
What is the function of the BHE and BLE pins on the 71016S20PHGI8?
The BHE (Bus High Enable) and BLE (Bus Low Enable) pins on the 71016S20PHGI8 provide independent gating for the upper (I/O8–I/O15) and lower (I/O0–I/O7) byte lanes of the 16-bit data bus. When BHE is LOW and BLE is HIGH, only the high byte is active during read/write; conversely, BLE LOW + BHE HIGH enables the low byte. Both LOW performs full 16-bit word access. This eliminates need for external byte demultiplexing logic and allows seamless integration with 8-bit peripherals or partial-word memory-mapped registers. The 71016S20PHGI8 truth table confirms these states are fully decoded internally.
Is the 71016S20PHGI8 RoHS-compliant and halogen-free?
Yes, the 71016S20PHGI8 is a "Green" device per Renesas' ordering information footnote, meaning it complies with RoHS Directive 2011/65/EU and is halogen-free (per IEC 61249-2-21). The "G" suffix in the part number (PHGGI8) explicitly denotes green packaging. Lead finish is matte tin, and all materials meet Renesas' restricted substance standards. Full compliance documentation-including test reports and declarations-is available through Renesas' official product page and authorized distributors like Digi-Key and Mouser for the 71016S20PHGI8.
