Product details
Overview
71V124SA15TYG8 from Renesas Electronics is a 128K × 8 (1 Mbit) high-speed CMOS static RAM with JEDEC center-power/ground pinout, 15 ns read/write cycle time, single 3.3 V supply operation, and industrial temperature range (–40°C to +85°C). It serves as fast, asynchronous main or cache memory in embedded controllers, network interface cards, and real-time data acquisition systems.
For engineers reviewing the 71V124SA15TYG8 datasheet, 71V124SA15TYG8 pinout, 71V124SA15TYG8 application, or 71V124SA15TYG8 equivalent, key selection criteria include access time consistency (tAA = tRC = 15 ns), LVTTL-compatible I/O, low-standby current (ISB1 = 10 mA), and TSOP/SOJ package compatibility for space-constrained PCB layouts.
Technical Context
The 71V124SA15TYG8 implements fully static asynchronous logic-no clocks or refresh required-and uses center-aligned VDD/GND pins (pins 16 and 17 in SOJ) to minimize simultaneous switching noise. Its dual-control architecture supports independent chip select (CS) and output enable (OE) for flexible bus timing control.
All inputs and outputs are LVTTL-compatible with VIH(min) = 2.0 V and VIL(max) = 0.8 V at VDD = 3.3 V, and it guarantees tOE ≤ 7 ns and tCLZ ≤ 4 ns under AC load conditions. Standby power is minimized via CS-driven full-static disable (ISB1 = 10 mA, independent of frequency).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 128K × 8-bit (1,048,576 bits); supports byte-wide parallel data interface without external multiplexing |
| Access/Cycle Time | 15 ns (tAA, tRC, tWC); ensures deterministic latency for real-time firmware execution and burst data buffering |
| Supply Voltage | 3.3 V ±10% (3.0–3.6 V); compatible with standard LVTTL logic rails and eliminates need for level shifters |
| Operating Temperature | –40°C to +85°C; qualified for industrial-grade deployment in base stations, motor drives, and factory automation |
| Standby Current | ISB1 = 10 µA (static); enables ultra-low-power sleep modes in battery-backed or energy-sensitive systems |
| I/O Compatibility | LVTTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V); interoperable with FPGA I/O banks, microcontroller GPIOs, and ASIC interfaces |
| Package | 32-pin 300-mil Plastic SOJ (PJG32); surface-mount footprint with gull-wing leads for reflow assembly and thermal reliability |
Pinout & Package
71V124SA15TYG8 is housed in a 32-pin 300-mil Plastic SOJ (PJG32) package with JEDEC-standard center power/ground layout-VDD on pin 16 and GND on pin 17-to suppress ground bounce and improve signal integrity in high-speed buses.
| 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-compliant I/O lines; high-impedance when CS or OE is inactive; supports shared bus arbitration |
| CS | Chip Select | Active-low enable controlling device activation; tACS = 15 ns defines earliest valid data after CS assertion |
| OE | Output Enable | Active-low control for output drivers only; tOE = 7 ns determines read-data validity window relative to OE transition |
| WE | Write Enable | Active-low write strobe; controls data capture on rising edge of WE while CS is low; tWP = 10 ns minimum pulse width |
| VDD | Power Supply | 3.3 V core supply (pin 16); center placement reduces simultaneous switching noise across all I/Os |
| GND | Ground Reference | Signal and power return (pin 17); adjacent to VDD for optimal decoupling and EMI suppression |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Center Power/Ground Pinout | Reduces ground bounce and crosstalk by minimizing current loop area-critical for >50 MHz bus operation |
| Fully Static Asynchronous Operation | Eliminates clock distribution, refresh circuitry, and associated timing constraints-simplifies system design and lowers BOM count |
| Dual Control (CS + OE) | Enables partial bus driving: OE can gate outputs independently of CS, allowing multi-drop bus sharing without full deselection |
| Low-Power Standby Mode | ISB1 = 10 µA static current ensures minimal leakage during idle periods-extends runtime in portable or remote-sensor applications |
| LVTTL-Compatible I/O | Direct interface to 3.3 V FPGAs, ARM Cortex-M MCUs, and Xilinx Zynq PS/PL without level-shifting components |

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, 3.3 V, 32-pin TSOP II; higher latency but wider industrial temp support (–40°C to +105°C) | Suitable for cost-sensitive designs where 15 ns speed is not required but extended temperature margin is critical | Select when thermal derating or long-term reliability at >85°C is prioritized over bandwidth |
| AS6C1008-15TIN | 128K × 8, 15 ns, 3.3 V, 32-pin TSOP II; identical speed but lacks center power/ground pinout and has higher ISB (25 µA) | Acceptable for non-noise-sensitive consumer or lab equipment where board-level decoupling suffices | Choose if footprint compatibility with PHG32 is needed but JEDEC noise reduction is not mandatory |
Compared with CY62128EV30LL-45ZSXI and AS6C1008-15TIN, the 71V124SA15TYG8 uniquely delivers 15 ns performance with JEDEC-optimized pinout and 10 µA static standby-making it optimal for noise-sensitive, latency-critical industrial and avionics memory buffers where both speed and signal integrity are non-negotiable.

FAQ
What is the maximum operating frequency supported by the 71V124SA15TYG8?
The 71V124SA15TYG8 does not operate on a clock; it is an asynchronous SRAM. Its 15 ns cycle time (tRC) corresponds to a maximum effective throughput of approximately 66.7 million operations per second. This timing is guaranteed across the full industrial temperature range (–40°C to +85°C) and 3.0–3.6 V supply, with no clock required for operation.
Does the 71V124SA15TYG8 require refresh circuitry or external clock signals?
No, the 71V124SA15TYG8 uses fully static CMOS memory cells and requires neither refresh cycles nor clock inputs. Its operation is purely address/data/control driven-CS, OE, and WE transitions alone govern read/write behavior. This eliminates timing constraints associated with DRAM controllers and simplifies integration into microcontroller- or FPGA-based systems.
What package type and lead finish does the 71V124SA15TYG8 use?
The 71V124SA15TYG8 is supplied in a 32-pin 300-mil Plastic SOJ (PJG32) package with matte tin (Sn) lead finish. The "8" suffix in the part number explicitly denotes tape-and-reel packaging-standard for automated SMT assembly-and the SOJ form factor supports reliable reflow soldering and thermal cycling performance in industrial environments.
How does the center power/ground pinout improve system performance in the 71V124SA15TYG8?
The 71V124SA15TYG8 places VDD on pin 16 and GND on pin 17-centered within the 32-pin SOJ array-to minimize simultaneous switching output (SSO) noise and reduce ground bounce. This layout lowers inductive coupling between power and signal paths, enabling cleaner signal edges and improved timing margins in high-speed parallel buses-especially critical for systems operating near 66 MHz effective bandwidth.
Is the 71V124SA15TYG8 RoHS-compliant and halogen-free?
Yes, the 71V124SA15TYG8 is a green-part variant (per Renesas ordering nomenclature "G") and complies with RoHS Directive 2011/65/EU and JEDEC JS709E for halogen content. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and meets IPC-4101D/126 requirements for printed board material compatibility.
