Product details
Overview
71V124SA10PHG8 from Renesas Electronics is a 128K × 8-bit, 1 Mbit high-speed CMOS static RAM with 10 ns access time, JEDEC center-power/ground pinout, LVTTL-compatible I/O, and single 3.3 V supply operation. It serves as main or cache memory in embedded controllers, network interface cards, and real-time data buffering systems requiring deterministic asynchronous read/write timing.
For engineers reviewing the 71V124SA10PHG8 datasheet, 71V124SA10PHG8 pinout, 71V124SA10PHG8 application, or 71V124SA10PHG8 equivalent, key selection criteria include tAA ≤ 10 ns, tRC = 10 ns, industrial-grade thermal stability (–40°C to +85°C), TSOP-32 package compatibility, and low-standby current (ISB1 = 10 mA) under full deselect.
Technical Context
The 71V124SA10PHG8 implements fully static asynchronous circuitry-no clocks or refresh cycles required-and uses dual-control logic with independent Chip Select (CS) and Output Enable (OE) for flexible bus arbitration. Its center-power/ground pinout (VDD on pins 4 & 24, GND on pins 13 & 20) minimizes simultaneous switching noise in high-density PCB layouts.
Read operations support two timing modes: CS-controlled (tACS = 10 ns) and OE-controlled (tOE = 5 ns), while write cycles are governed by WE-active overlap with CS (tWP = 7 ns min). All I/Os meet LVTTL voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and drive ±4 mA/±8 mA loads at VOH/ VOL specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 128K × 8-bit (1,048,576 bits), byte-wide parallel interface |
| Access Time (tAA) | 10 ns maximum - guarantees address-to-data valid latency for 100 MHz burst-read timing budgets |

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 |
|---|---|---|---|
| CY62128EV30LL-10ZSXI | 128K × 8-bit, 10 ns, 3.3 V, SOIC-32 package; lacks center-power pinout and has higher ISB (25 µA) | Preferred where board space permits wider SOIC footprint and noise margin exceeds 15 dB | Select when legacy SOIC layout reuse is prioritized over TSOP density and lowest standby power |
| AS6C1008-10TIN | 128K × 8-bit, 10 ns, 3.3 V, TSOP-32; lower ICC (120 mA) but no industrial temp rating (0°C to +70°C only) | Suitable for commercial-grade consumer electronics with tighter thermal envelopes | Choose for cost-sensitive designs where extended temperature operation is not required |

FAQ
What is the operating temperature range for the 71V124SA10PHG8?
The 71V124SA10PHG8 is rated for commercial temperature operation from 0°C to +70°C. This grade is explicitly confirmed in the Renesas ordering information table for part number 71V124SA10PHG8, which lists "C" under Temp. Grade. Industrial variants (e.g., 71V124SA10PHGI8) exist but are distinct orderables.
Does the 71V124SA10PHG8 require a refresh circuit or clock signal?
No, the 71V124SA10PHG8 uses fully static CMOS memory cells and asynchronous control logic-no clock, timer, or periodic refresh circuitry is needed. Its operation depends solely on address, CS, OE, and WE timing, as confirmed in the Functional Block Diagram and Truth Table sections of the Renesas datasheet.
What package type and pin count does the 71V124SA10PHG8 use?
The 71V124SA10PHG8 uses a 32-pin Type II TSOP package with PHG32 footprint. This is unambiguously specified in the Ordering Information section, where "PHG" maps to TSOP Type II and "32" denotes pin count; the pin configuration diagram (Figure 2) confirms all 32 terminals including dual VDD and dual GND placements.
Can the 71V124SA10PHG8 be used with 5 V logic interfaces?
No-the 71V124SA10PHG8 is strictly a 3.3 V LVTTL device with VIH(max) = VDD + 0.3 V and absolute maximum VIN of VDD + 0.5 V. Applying 5 V signals violates Absolute Maximum Ratings and risks permanent damage, as stated in Table 2 (Absolute Maximum Ratings) of the Renesas datasheet.
What is the minimum write pulse width (tWP) specification for the 71V124SA10PHG8?
The minimum write pulse width (tWP) for the 71V124SA10PHG8 is 7 ns, as specified in the AC Electrical Characteristics table (Table 8) under WRITE CYCLE parameters for the 71V124SA10 speed grade. This value is guaranteed across the full commercial temperature range and supply voltage (3.15–3.6 V).
