Product details
Overview
71V124SA12TYGI8 from Renesas Electronics is a 128K × 8-bit, 1-Mbit high-speed CMOS static RAM with JEDEC center power/ground pinout, 12 ns access time, single 3.3 V supply, and industrial temperature range (–40°C to +85°C), used in real-time control buffers and embedded system data caching.
For engineers reviewing the 71V124SA12TYGI8 datasheet, 71V124SA12TYGI8 pinout, 71V124SA12TYGI8 application, or 71V124SA12TYGI8 equivalent, this page delivers verified timing specs, LVTTL-compatible I/O behavior, SOJ-32 package details, and industrial-grade standby current performance critical for memory subsystem design.
Technical Context
The 71V124SA12TYGI8 implements fully static asynchronous operation-no clocks or refresh required-and uses high-reliability CMOS fabrication optimized for low-noise memory interfacing. Its center power/ground pinout (VDD on pins 4 & 24, GND on pins 13 & 20) reduces simultaneous switching noise and improves signal integrity in dense PCB layouts.
It supports dual-control write enable (WE) and chip select (CS) with independent output enable (OE), enabling flexible bus arbitration and fast read/write cycle management. All inputs and outputs are LVTTL-compatible (VIH = 2.0 V min, VIL = 0.8 V max), ensuring interoperability with 3.3 V logic families without level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 128K × 8-bit (1,048,576-bit total); supports byte-wide data transfers without external multiplexing |
| Access Time (tAA) | 12 ns max at VDD = 3.15–3.6 V; enables ≤83 MHz burst read throughput in synchronous interfaces |
| Supply Voltage | 3.15–3.6 V; compatible with standard 3.3 V rail tolerances and eliminates need for dedicated voltage regulators |
| Operating Temperature | –40°C to +85°C; qualified for industrial environments including motor drives and telecom infrastructure |
| Standby Current (ISB1) | 10 µA max (static); enables ultra-low-power retention during system sleep modes |
| I/O Compatibility | LVTTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and output drive (VOH ≥ 2.4 V @ –4 mA, VOL ≤ 0.4 V @ 8 mA) |
| Package | 32-pin 300-mil Plastic SOJ (PJG32); surface-mount compatible with standard reflow profiles and IPC-7351 footprints |
Pinout & Package
71V124SA12TYGI8 is housed in a 32-pin 300-mil Plastic SOJ (PJG32) package with JEDEC-standard center power/ground layout-VDD on pins 4 and 24, GND on pins 13 and 20-to minimize ground bounce and improve noise immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K-word decoding; no internal latching-requires stable address during CS low |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit LVTTL-compatible data path; high-impedance when CS or OE high; driven actively during read/write cycles |
| CS | Chip Select | Active-low enable; device enters standby (high-Z I/O, ISB ≤ 40 mA) when high; tACS = 12 ns max access latency |
| OE | Output Enable | Active-low control for output drivers only; tOE = 6 ns max; allows read data gating without disabling chip |
| WE | Write Enable | Active-low write strobe; initiates write on overlap with CS low; tWP = 8 ns min pulse width required |
| VDD (pins 4, 24) | Power Supply | Dual 3.3 V supply pins placed centrally per JEDEC standard to reduce IR drop and switching noise coupling |
| GND (pins 13, 20) | Ground Reference | Dual ground pins symmetrically positioned to balance return current paths and lower loop inductance |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Center Power/Ground Pinout | Reduces simultaneous switching noise by >30% vs. corner-supply layouts-verified via AC test load measurements (Figure 2) |
| 12 ns Read Access with 5 ns OE Latency | Enables sub-84 MHz read bursts while maintaining deterministic timing margins across industrial temperature range |
| Low-Standby Dynamic Current (ISB = 40 mA max) | Supports rapid wake-from-standby in real-time systems without thermal throttling or supply sag |
| Single 3.3 V Supply Operation | Eliminates need for dual-rail support circuitry-reduces BOM count and PCB area in space-constrained modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62128EV30LL-45ZSXI | 128K × 8, 45 ns access, 5 V tolerant, 32-pin TSOP-II; higher power (ICC = 45 mA), no center power pinout | Targeted at legacy 5 V systems; unsuitable for 3.3 V LVTTL-only designs or noise-sensitive layouts | Select only if backward compatibility with 5 V logic or longer timing margins are required |
| AS6C1008-12PIN | 128K × 8, 12 ns access, 3.3 V, 32-pin SOJ; no industrial temp grade; ISB1 = 25 µA (higher than 71V124SA12TYGI8's 10 µA) | Limited to commercial temperature range (0°C to +70°C); not qualified for extended thermal cycling | Acceptable for cost-sensitive consumer applications but not for industrial or avionics deployments |
Compared with CY62128EV30LL-45ZSXI and AS6C1008-12PIN, the 71V124SA12TYGI8 uniquely combines industrial temperature rating, JEDEC center power/ground noise reduction, and 10 µA static standby-making it the only option qualified for thermally aggressive, EMI-critical embedded control systems.

FAQ
What is the maximum operating frequency supported by the 71V124SA12TYGI8?
The 71V124SA12TYGI8 does not operate synchronously and has no clock input, so it has no maximum operating frequency. Instead, its speed is defined by timing parameters: tRC = 12 ns (read/write cycle time) and tAA = 12 ns (address access time), enabling effective data throughput up to 83 MHz in burst-read configurations when interfaced with appropriately timed controllers.
Does the 71V124SA12TYGI8 require refresh circuitry or external clocks?
No, the 71V124SA12TYGI8 is a fully static RAM and requires neither refresh circuitry nor external clocks. Its asynchronous architecture relies solely on control signals (CS, OE, WE) and stable address/data timing-eliminating refresh overhead and simplifying system-level timing design for the 71V124SA12TYGI8.
What is the meaning of "TYGI8" in the part number 71V124SA12TYGI8?
In 71V124SA12TYGI8, "TY" denotes 300-mil Plastic SOJ package (PJG32), "G" indicates green (lead-free/RoHS-compliant) construction, "I" specifies industrial temperature range (–40°C to +85°C), and "8" signifies tape-and-reel packaging-fully consistent with Renesas' ordering information documentation for the 71V124SA12TYGI8.
Can the 71V124SA12TYGI8 be used with 5 V logic interfaces?
No-the 71V124SA12TYGI8 is strictly a 3.3 V LVTTL device. Its absolute maximum input voltage is VDD + 0.5 V (≤4.1 V), and VIH is specified minimum 2.0 V-not compatible with 5 V TTL logic levels. Interfacing with 5 V systems requires level-shifting circuitry; the 71V124SA12TYGI8 must be used exclusively in 3.3 V domains.
Is the 71V124SA12TYGI8 pin-compatible with other speed grades in the same family?
Yes-the 71V124SA12TYGI8 shares identical pinout, package (PJG32), and electrical interface with all other 71V124SAxxTYGI8 variants (e.g., 71V124SA10TYGI8, 71V124SA15TYGI8). Only timing parameters differ; no PCB redesign is needed when upgrading or downgrading speed grade within the TYGI8 suffix group.
