Product details
Overview
71V424S10PHG8 from Renesas Electronics is a 4-Mbit (512K × 8) high-speed CMOS static RAM with 10 ns access time, single 3.3 V supply operation, TTL-compatible I/O, and JEDEC-standard center-power/ground pinout for noise reduction. It serves as main or cache memory in embedded controllers, network interface cards, and real-time data buffering systems requiring deterministic low-latency read/write cycles.
For engineers reviewing the 71V424S10PHG8 datasheet, 71V424S10PHG8 pinout, 71V424S10PHG8 application, or 71V424S10PHG8 equivalent, this page delivers verified timing parameters, package-specific terminal roles, industrial-grade thermal performance, and direct alternative options for memory subsystem redesign or BOM optimization.
Technical Context
The 71V424S10PHG8 implements fully static asynchronous circuitry-no clocks or refresh required-and uses high-reliability CMOS fabrication to achieve 10 ns address access time (tAA), 10 ns read cycle time (tRC), and 5 ns output enable delay (tOE). Its dual control architecture supports both chip-select–driven and output-enable–driven read cycles, enabling flexible bus arbitration in multi-master systems.
All 8 bidirectional I/O lines (I/O0–I/O7) operate at TTL voltage levels with guaranteed VOH ≥ 2.4 V at –4 mA and VOL ≤ 0.4 V at 8 mA under worst-case VDD = 3.0 V. Standby current is 20 mA (ISB1) in full static mode, and dynamic operating current is 180 mA at fMAX under commercial temperature conditions.

| VSS | Ground | Signal and power ground reference; center-placed adjacent to VDD per JEDEC standard |
| NC | No Connect | Pins 2, 3, 23, 24, 25, 26, 27, 32 - electrically isolated; must remain unconnected |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62148EV30LL-10ZSXI | 512K × 8, 10 ns, 3.3 V, 44-pin TSOP; lower ISB1 (15 mA) but higher tCHZ (8 ns) | Better standby efficiency in battery-backed systems; slower output disable may limit bus turnaround in high-frequency burst reads | Select when lowest static power dominates over bus release timing constraints |
| AS6C4008-10TIN | 512K × 8, 10 ns, 3.3 V, 44-pin TSOP; wider VDD range (2.7–3.6 V), higher input capacitance (10 pF) | Enhanced supply tolerance suits brown-out-prone automotive power domains; added input loading affects high-speed trace routing | Select when system-level VDD regulation margin is insufficient for strict 3.0–3.6 V spec of 71V424S10PHG8 |
Compared with CY62148EV30LL-10ZSXI and AS6C4008-10TIN, the 71V424S10PHG8 offers tighter tCHZ (7 ns) and JEDEC-optimized pinout for noise-sensitive applications, while maintaining industry-standard timing compatibility and commercial-temperature reliability for cost-sensitive embedded designs.

FAQ
What is the maximum clock frequency supported by the 71V424S10PHG8?
The 71V424S10PHG8 is an asynchronous SRAM and does not use a clock signal. Its maximum operational speed is defined by timing parameters: 10 ns read cycle time (tRC) and 10 ns address access time (tAA), enabling reliable interface with microprocessors or FPGAs operating up to 100 MHz bus frequencies under appropriate setup/hold conditions.
Does the 71V424S10PHG8 require refresh circuitry?
No, the 71V424S10PHG8 is a fully static RAM and requires no refresh cycles. Its CMOS latch-based memory cells retain data indefinitely as long as VDD remains within specification and CS is asserted during active access - a key advantage over DRAM in deterministic real-time systems.
What is the meaning of "PHG8" in the part number 71V424S10PHG8?
In 71V424S10PHG8, "PHG" denotes the 44-pin TSOP Type II package (PHG44), and "8" indicates tape-and-reel packaging format per JEDEC standards. The "S" identifies the standard power variant, and "10" specifies the 10 ns speed grade - all confirmed in Renesas' official ordering information tables.
Can the 71V424S10PHG8 operate at 2.5 V?
No. The 71V424S10PHG8 is specified only for 3.3 V operation, with absolute minimum VDD = 3.0 V and maximum = 3.6 V. Operation below 3.0 V violates DC operating conditions and risks data corruption, timing violations, or failure to drive TTL-compatible outputs reliably.
Is the 71V424S10PHG8 pin-compatible with the 71V424L10PHG8?
Yes - both 71V424S10PHG8 and 71V424L10PHG8 share identical 44-pin TSOP (PHG44) packaging, pinout, and functional interface. The sole difference is power profile: "S" denotes standard power (180 mA ICC), while "L" denotes low power (165 mA ICC); no PCB changes are required for substitution in most thermal- and timing-margin-sufficient designs.
