Product details
Overview
71V416S12PHGI8 from Renesas Electronics is a 4-Mbit (256K × 16) high-speed CMOS static RAM with 12 ns access time, single 3.3 V supply operation, LVTTL-compatible I/O, and industrial temperature range (–40°C to +85°C). It features separate byte enable (BHE/BLE), output enable (OE), and chip select (CS) for flexible memory control in embedded controllers and data acquisition systems.
For engineers reviewing the 71V416S12PHGI8 datasheet, 71V416S12PHGI8 pinout, 71V416S12PHGI8 application, or 71V416S12PHGI8 equivalent, key selection criteria include its 12 ns read cycle time, TSOP Type II (44-pin, 400 mil) package, industrial-grade reliability, byte-level write capability, and low-power standby current of 60 mA (max) under dynamic conditions.
Technical Context
The 71V416S12PHGI8 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 (BHE/BLE) enables independent 8-bit writes without external logic, while JEDEC-standard center power/ground pinout minimizes switching noise in dense PCB layouts.
Timing is controlled via three independent enable paths: CS-controlled, OE-controlled, and BHE/BLE-controlled write cycles, each with defined setup/hold and transition-to-valid parameters. All inputs meet LVTTL voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and outputs drive ±4 mA/±8 mA loads with VOH ≥ 2.4 V and VOL ≤ 0.4 V at VDD = 3.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4,194,304 bits (256K × 16), supporting word-aligned 16-bit data buses without glue logic. |
| Access Time (tAA) | 12 ns max - guarantees address-to-data valid delay for real-time interrupt response in microcontroller peripherals. |
| Supply Voltage | 3.0 V to 3.6 V - compatible with modern 3.3 V system rails and tolerant of typical board-level regulation ripple. |
| Operating Temperature | –40°C to +85°C - qualified for industrial automation, motor control, and outdoor communications equipment. |
| Standby Current (ISB) | 60 mA max (dynamic), 10 mA max (static) - enables low-power sleep modes in battery-backed or energy-sensitive systems. |
| I/O Interface | LVTTL-compatible bidirectional data (I/O0–I/O15) - interoperable with FPGA I/O banks, ASICs, and microcontrollers without level shifters. |

Pinout & Package
71V416S12PHGI8 is supplied in a 44-pin, 400 mil TSOP Type II package (PHG44) with JEDEC-standard center power/ground layout for noise reduction. Pin 1 is located at the bottom-left corner when the notch faces upward.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word addressing; no internal address latching required. |
| CS | Chip Select | Active-low enable controlling device activation; must be stable before address or control transitions. |
| OE | Output Enable | Active-low control enabling bidirectional I/O pins as outputs during read cycles; tOE = 6 ns max. |

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-45ZSXI | 4-Mbit (256K × 16), 45 ns access, 3.3 V, SOIC-44 package; higher access time, no byte enables. | Suitable only for non-real-time buffering where >40 ns latency is acceptable; lacks BHE/BLE for partial writes. | Select only if cost sensitivity outweighs timing and flexibility requirements; not suitable for interrupt-driven systems. |
| AS6C4008-12TIN | 4-Mbit (256K × 16), 12 ns access, 3.3 V, TSOP-44; identical speed but no industrial temp grade (0°C to +70°C only). | Restricted to commercial environments; fails qualification for extended temperature cycling in automotive or industrial deployments. | Acceptable for lab-grade instruments or short-lifecycle consumer devices; avoid for field-deployed hardware requiring –40°C startup. |
Compared with CY62167EV30LL-45ZSXI and AS6C4008-12TIN, the 71V416S12PHGI8 uniquely combines 12 ns performance, industrial temperature support, byte-enable functionality, and JEDEC-compliant TSOP packaging-making it the only option among the three qualified for deterministic real-time embedded memory subsystems.

FAQ
What is the maximum operating frequency supported by the 71V416S12PHGI8?
The 71V416S12PHGI8 does not operate on a clock; it is an asynchronous SRAM. Its 12 ns access time (tAA) and 12 ns read cycle time (tRC) support effective data throughput up to 83 MHz in burst-read configurations. System-level frequency depends on controller timing margins, but the 71V416S12PHGI8 itself imposes no clock requirement and needs no refresh cycles.
Does the 71V416S12PHGI8 require external pull-up resistors on its control pins?
No, the 71V416S12PHGI8 has internally biased inputs compliant with LVTTL logic levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and no external pull-ups are required for CS, OE, WE, BHE, or BLE under normal operation. External termination is only needed for impedance matching on long traces (>10 cm) in high-speed layouts.
Can the 71V416S12PHGI8 be used in place of the 71V416S10PHGI8?
Yes, the 71V416S12PHGI8 is a functional drop-in replacement for the 71V416S10PHGI8 in designs where 12 ns timing meets system requirements. Both share identical pinout, voltage specs, and feature set. However, the 10 ns version offers tighter timing margins; verify tAA, tRC, and tOE values against your controller's setup/hold windows before substitution.
What is the meaning of the 'I' and '8' suffixes in 71V416S12PHGI8?
In 71V416S12PHGI8, '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' identifies the 44-pin TSOP Type II package, and '12' specifies the 12 ns speed grade. This full ordering code ensures traceable, production-ready sourcing.
Is the 71V416S12PHGI8 RoHS and REACH compliant?
Yes, the 71V416S12PHGI8 is a green-part variant (as indicated by the 'G' in alternate order codes like 71V416S12PHGI8), fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead-free soldering compatibility is validated per J-STD-020D moisture sensitivity level 3 (MSL-3) for standard reflow profiles.
