Product details
Overview
71V124SA10YG8 from Renesas Electronics is a 128K × 8 (1 Mbit), 3.3 V CMOS static RAM with 10 ns access time, JEDEC center-power/ground pinout, LVTTL-compatible I/O, and industrial-grade operation (–40°C to +85°C) in 32-pin 400-mil SOJ package. It serves as high-speed asynchronous memory in embedded controllers, network packet buffers, and real-time data acquisition systems.
For engineers reviewing the 71V124SA10YG8 datasheet, 71V124SA10YG8 pinout, 71V124SA10YG8 application, or 71V124SA10YG8 equivalent, key selection criteria include guaranteed 10 ns tAA and tRC timing, low-impedance output enable (tOE ≤ 5 ns), standby current of 10 mA max, and compatibility with 3.3 V LVTTL logic families in noise-sensitive board layouts.
Technical Context
The 71V124SA10YG8 implements fully static asynchronous architecture-no clocks, no refresh required-and uses center-aligned VDD/GND pins (pins 16 & 17) to minimize simultaneous switching noise. Its dual control scheme supports both CS-controlled and OE-controlled read cycles, with independent WE gating for write operations.
All inputs meet LVTTL voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and outputs drive ±4 mA/±8 mA loads while maintaining VOL ≤ 0.4 V and VOH ≥ 2.4 V at VDD = 3.15 V. Dynamic ICC is 145 mA max at fMAX, with ISB1 static standby current fixed at 10 µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 128K × 8-bit (1,048,576 bits), byte-wide asynchronous SRAM |

Pinout & Package
32-pin plastic SOJ (PBG32) package with 400-mil body width and gull-wing leads. JEDEC-compliant center-power/ground layout reduces ground bounce and improves signal integrity in high-speed parallel buses.

|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K-word decoding; TTL-compatible thresholds |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit LVTTL I/O with 3-state control via OE/CS; supports shared bus topology |
| CS | Chip Select | Active-low enable; controls device selection and dynamic current draw (ICC/ISB) |
| OE | Output Enable | Active-low; gates output drivers independently of CS for flexible bus timing |
| WE | Write Enable | Active-low; initiates write cycle when CS is active; defines tWP and tDW timing windows |
| VDD | Power Supply | Pin 16 - center-positioned for reduced supply noise coupling into adjacent signals |
| GND | Ground | Pin 17 - adjacent to VDD per JEDEC pinout; minimizes loop inductance for clean return path |

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-10ZSXI | 128K × 8, 3.3 V, 10 ns, TSOP-32; higher ICC (160 mA), no center-power pinout | Lacks noise-reduction pinout; requires additional decoupling in EMI-critical avionics | Prefer when TSOP footprint is mandatory and board-level noise mitigation is already implemented |
| AS6C1008-10TIN | 128K × 8, 3.3 V, 10 ns, SOJ-32; 55 mA ICC, but only commercial temp (0°C to +70°C) | Not rated for industrial ambient; unsuitable for extended outdoor or under-hood use | Select only for cost-sensitive commercial equipment with controlled thermal environments |
Compared with CY62128EV30LL-10ZSXI and AS6C1008-10TIN, the 71V124SA10YG8 uniquely combines industrial temperature qualification, JEDEC center-power pinout for noise immunity, and 10 ns timing in the same 400-mil SOJ package-enabling drop-in replacement where reliability and signal integrity are co-prioritized.

FAQ
What is the maximum operating frequency supported by the 71V124SA10YG8?
The 71V124SA10YG8 is an asynchronous SRAM with no internal clock; its effective maximum interface rate is determined by tRC = 10 ns, supporting up to 100 MHz burst transfers when interfaced with appropriately timed control logic. It does not require clocking or synchronization circuits.
Does the 71V124SA10YG8 require external refresh circuitry?
No, the 71V124SA10YG8 is a fully static CMOS SRAM and requires no refresh cycles, clocks, or periodic access to retain data. This eliminates refresh overhead in microcontroller or FPGA-based systems and simplifies timing design.
Is the 71V124SA10YG8 pin-compatible with other speed grades in the same package?
Yes, all 71V124SA variants-including 71V124SA10YG8, 71V124SA12YG8, and 71V124SA15YG8-share identical 32-pin PBG32 SOJ pinouts and electrical interfaces; only access timing parameters differ, allowing direct substitution where timing margins permit.
What is the meaning of "Green" in the 71V124SA10YG8 ordering code?
The "G" suffix in 71V124SA10YG8 indicates compliance with RoHS Directive 2011/65/EU and Renesas' green manufacturing standards: lead-free terminations, halogen-free molding compound, and absence of intentionally added antimony, beryllium, cobalt, or nickel in excess of regulatory thresholds.
Can the 71V124SA10YG8 operate reliably at VDD = 3.0 V?
No-the 71V124SA10YG8 is specified for VDD = 3.15 V to 3.6 V only. Operation at 3.0 V falls outside guaranteed specifications; DC parameters like VIH (min. 2.0 V) and tAA (10 ns) are not validated below 3.15 V, and functional failure may occur.
