Product details
Overview
71V424S15YGI from Renesas Electronics is a 4-Mbit (512K × 8) high-speed CMOS static RAM with 15 ns read/write cycle time, single 3.3 V supply operation, and industrial temperature range (–40°C to +85°C). It features TTL-compatible bidirectional I/O, JEDEC-standard center-power/ground pinout for noise reduction, and low-power standby modes - deployed in real-time industrial controllers requiring deterministic memory access.
For engineers reviewing the 71V424S15YGI datasheet, 71V424S15YGI pinout, 71V424S15YGI application, or 71V424S15YGI equivalent, this page delivers verified timing parameters, SOJ-36 package layout, industrial-grade DC/AC electrical specs, and direct alternative options for memory subsystem redesign or BOM optimization.
Technical Context
The 71V424S15YGI uses fully static asynchronous circuitry-no clocks or refresh required-and supports both CS-controlled and WE-controlled write cycles. Its address access time (tAA) and chip select access time (tACS) are both guaranteed ≤15 ns across the full industrial temperature range.
It implements a 19-bit address bus (A0–A18), eight bidirectional data lines (I/O0–I/O7), and three control inputs (CS, OE, WE) with defined high-impedance output behavior during deselect or write disable. Input leakage current is ≤5 µA, and output drive meets TTL voltage thresholds at ±4 mA (VOH ≥2.4 V, VOL ≤0.4 V) under min VDD conditions.
Key Specifications

Pinout & Package
71V424S15YGI is housed in a 36-pin, 400 mil plastic SOJ (PBG36) package with JEDEC-compliant center-power/ground pinout for reduced switching noise and improved signal integrity.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus supporting full 512K-word addressing; no address multiplexing required |

| VDD | Power Supply | 3.3 V core supply; decoupling recommended per JEDEC SOJ layout guidelines |
| VSS | Ground | System ground reference; center-placed for optimal noise suppression in high-speed operation |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| CY62157EV30LL-15ZSXIT | 512K × 8, 15 ns, 3.3 V, TSOP-44 package; ISB1 = 25 µA (lower than 71V424S15YGI's 10 mA) | TSOP-44 footprint requires PCB redesign; better suited for space-constrained telecom modules | Select when ultra-low standby current is critical and board layout allows TSOP-44 replacement |
| AS6C4008-15TIN | 512K × 8, 15 ns, 3.3 V, SOJ-36 package; commercial temp only (0°C to +70°C); ISB1 = 2 mA | Lacks industrial temperature rating; not qualified for extended thermal cycling or harsh environments | Acceptable for cost-sensitive consumer or lab equipment where ambient temperature remains controlled |
Compared with CY62157EV30LL-15ZSXIT and AS6C4008-15TIN, the 71V424S15YGI uniquely combines SOJ-36 compatibility, industrial temperature qualification, and balanced dynamic/standby power-making it the preferred choice for retrofitting legacy industrial PCBs without layout changes.

FAQ
What is the maximum clock frequency supported by the 71V424S15YGI?
The 71V424S15YGI is an asynchronous SRAM and does not use a clock signal. Its performance is defined by timing parameters such as tRC (15 ns read cycle time), enabling reliable operation in systems with bus frequencies up to approximately 66 MHz when interfaced with appropriate setup/hold margins. The 71V424S15YGI requires no clock distribution or synchronization circuitry.
Does the 71V424S15YGI support battery backup operation?
The 71V424S15YGI retains data as long as VDD remains within specification (3.0 V to 3.6 V); however, it has no built-in battery-switchover circuitry or dedicated VBAT pin. For battery-backed operation, external power-fail detection and hold circuitry must be implemented. The 71V424S15YGI's ISB1 = 10 mA standby current is compatible with typical coin-cell backup designs when paired with appropriate supervisory ICs.
Is the 71V424S15YGI pin-compatible with earlier IDT versions?
Yes - the 71V424S15YGI maintains identical pinout, electrical characteristics, and timing behavior as the original IDT-branded 71V424S15YGI. Renesas retained full functional and mechanical compatibility following the acquisition, including PBG36 SOJ package dimensions, JEDEC pin assignments, and AC/DC specifications across the industrial temperature range.
What is the meaning of "YGI" in the part number 71V424S15YGI?
In the 71V424S15YGI ordering code, "Y" denotes the PBG36 (36-pin SOJ) package, "G" indicates green (halogen-free/RoHS-compliant) material, and "I" specifies industrial temperature grade (–40°C to +85°C). This suffix confirms the device is supplied in a lead-free, surface-mount SOJ package rated for harsh environmental operation - a key identifier for industrial BOM validation.
Can the 71V424S15YGI be used with 5 V microcontrollers?
The 71V424S15YGI features TTL-compatible inputs (VIH ≥2.0 V, VIL ≤0.8 V) and outputs (VOH ≥2.4 V at –4 mA), allowing safe interfacing with 5 V microcontrollers without level shifters - provided the 5 V device's output low voltage stays below 0.8 V and its input high threshold is ≤2.0 V. However, VDD must remain strictly at 3.3 V; applying 5 V to VDD will damage the 71V424S15YGI.
