Product details
Overview
71V016SA15PHGI8 from Renesas Electronics is a 64K × 16-bit (1 Mbit), high-speed CMOS static RAM with 15 ns access time, single 3.3 V supply operation, industrial temperature range (–40°C to +85°C), and LVTTL-compatible bidirectional I/O. It features separate byte enable (BHE/BLE), chip select (CS), output enable (OE), and write enable (WE) for flexible memory control in embedded microcontroller systems.
For engineers reviewing the 71V016SA15PHGI8 datasheet, 71V016SA15PHGI8 pinout, 71V016SA15PHGI8 application, or 71V016SA15PHGI8 equivalent, key selection criteria include its 15 ns read cycle time, industrial-grade reliability, 44-pin TSOP-II (PHG44) package compatibility, byte-level write capability, and low-power standby current of 35 mA (typical).
Technical Context
The 71V016SA15PHGI8 implements fully static asynchronous circuitry-no clocks or refresh required-and uses high-reliability CMOS technology optimized for deterministic timing. Its dual-byte enable architecture allows independent 8-bit writes to upper (I/O8–I/O15) and lower (I/O0–I/O7) data lanes without external logic.
Timing is controlled via three independent enable paths: CS-controlled, OE-controlled, and BHE/BLE-controlled read/write cycles, each with guaranteed parameters (e.g., tCLZ ≤ 5 ns, tOHZ ≤ 6 ns). All inputs and outputs meet LVTTL voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) at 3.3 V ±0.15 V supply.
Key Specifications

FAQ
What is the maximum operating frequency supported by the 71V016SA15PHGI8?
The 71V016SA15PHGI8 does not operate on a clock signal-it is an asynchronous SRAM. Its maximum effective interface rate is determined by its 15 ns read/write cycle time (tRC), supporting up to approximately 66.7 MHz bus operation when interfaced with controllers capable of meeting setup/hold timing. No internal clock or PLL is present.
Does the 71V016SA15PHGI8 require external refresh circuitry?
No, the 71V016SA15PHGI8 is a fully static RAM and requires no refresh cycles or external refresh circuitry. Its CMOS latch-based memory cells retain data indefinitely as long as power (VDD) and ground (VSS) are maintained within specification, making it ideal for low-overhead embedded memory applications.
Can the 71V016SA15PHGI8 be used with a 5 V microcontroller interface?
No-the 71V016SA15PHGI8 is strictly a 3.3 V LVTTL device with VIH minimum of 2.0 V and VIL maximum of 0.8 V. Direct connection to 5 V logic violates absolute maximum input voltage ratings (VIN ≤ VDD + 0.5 V = 4.1 V) and risks damage. Level-shifting circuitry is mandatory for 5 V system integration.
What is the meaning of the 'I8' suffix in 71V016SA15PHGI8?
In the Renesas ordering code 71V016SA15PHGI8, 'I' denotes Industrial temperature grade (–40°C to +85°C), and '8' indicates tape-and-reel packaging (8 mm carrier tape, 1,000 units per reel). The 'PHG' specifies 44-pin TSOP Type II package, and '15' is the 15 ns speed grade.
Is the 71V016SA15PHGI8 RoHS-compliant and halogen-free?
Yes-the 71V016SA15PHGI8 is RoHS-compliant and qualifies as a "Green" part per Renesas documentation. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and meets JEDEC JS709B halogen-free requirements.
