Product details
Overview
71V016SA12PHGI from Renesas Electronics is a 64K × 16-bit (1 Mbit), 3.3 V high-speed CMOS static RAM with 12 ns access time, industrial temperature range (–40°C to +85°C), LVTTL-compatible I/O, and dual byte enable (BHE/BLE) for flexible data bus control in embedded memory subsystems.
For engineers reviewing the 71V016SA12PHGI datasheet, 71V016SA12PHGI pinout, 71V016SA12PHGI application, or 71V016SA12PHGI equivalent, this device serves as a drop-in replacement for legacy SRAMs in FPGA configuration buffers, network packet buffering, and real-time control data storage where deterministic asynchronous timing and low-power standby are critical.
Technical Context
The 71V016SA12PHGI implements fully static asynchronous circuitry-no clocks or refresh required-and uses high-reliability CMOS technology optimized for stable operation across voltage (3.15–3.6 V) and temperature extremes. Its architecture supports independent high- and low-byte write enables, enabling partial-word writes without external logic.
Timing is controlled via three independent enable paths: chip select (CS), output enable (OE), and byte enables (BHE/BLE), each with guaranteed propagation delays (e.g., tCLZ ≤ 4 ns, tOE ≤ 6 ns). All inputs and outputs are LVTTL-compatible, ensuring seamless interfacing with 3.3 V microcontrollers, FPGAs, and ASICs.

FAQ
What is the maximum operating frequency supported by the 71V016SA12PHGI?
The 71V016SA12PHGI is an asynchronous SRAM with no clock input, so it does not have an operating frequency specification. Instead, its performance is defined by timing parameters: tRC (read cycle time) is 12 ns max, enabling effective operation up to ~83 MHz in systems with zero wait states and ideal bus timing. Actual system throughput depends on controller interface design and bus protocol overhead-not the 71V016SA12PHGI itself.
Does the 71V016SA12PHGI require external refresh circuitry?
No, the 71V016SA12PHGI is a fully static RAM and requires no refresh circuitry. Its CMOS latch-based memory cells retain data indefinitely as long as power (VDD) is applied and CS remains asserted during active use. This eliminates refresh overhead and simplifies system design compared to DRAM or pseudo-SRAM solutions.
Can the 71V016SA12PHGI be used with a 2.5 V microcontroller interface?
No-the 71V016SA12PHGI is specified only for 3.3 V operation (VDD = 3.15–3.6 V) and LVTTL-compatible signaling. Its VIH minimum is 2.0 V and VIL maximum is 0.8 V, but driving it from a 2.5 V system risks violating input voltage thresholds and may cause unreliable operation. A level translator or 3.3 V I/O domain is required for interoperability with 2.5 V controllers.
What is the meaning of "PHGI" in the part number 71V016SA12PHGI?
In 71V016SA12PHGI, "PHG" denotes the 44-pin TSOP Type II package (PHG44), and "I" indicates industrial temperature range (–40°C to +85°C). The "12" specifies 12 ns access time, "SA" identifies the 3.3 V core logic family, and "71V016" is the base device type. No other suffixes (e.g., "8", "G") are present in this specific orderable part.
Is the 71V016SA12PHGI pin-compatible with earlier IDT71V016 variants in TSOP packages?
Yes-the 71V016SA12PHGI uses the same PHG44 (44-pin TSOP Type II) pinout as all IDT71V016 SA-series devices in that package, including 71V016SA10PHGI and 71V016SA15PHGI. Address, data, control, and power pins are identically mapped; only timing specifications differ between speed grades. This enables drop-in replacement within the same package family.
