Product details
Overview
71V124SA15TYGI8 from Renesas Electronics is a 128K × 8-bit (1 Mbit), 3.3 V CMOS static RAM with 15 ns read/write cycle time, JEDEC center-power/ground pinout, LVTTL-compatible I/O, and industrial temperature support (–40°C to +85°C). It operates fully asynchronously without clocks or refresh, enabling use in real-time control buffers and legacy bus interfaces.
For engineers reviewing the 71V124SA15TYGI8 datasheet, 71V124SA15TYGI8 pinout, 71V124SA15TYGI8 application, or 71V124SA15TYGI8 equivalent, key selection criteria include its 15 ns access time, TSOP/SOJ package compatibility, industrial-grade reliability, low standby current (10 mA max), and center-GND noise-reduction layout.
Technical Context
The 71V124SA15TYGI8 implements a fully static asynchronous memory architecture with independent chip select (CS) and output enable (OE) controls, supporting both CS- and WE-controlled write timing modes. Its bidirectional 8-bit data bus (I/O0–I/O7) and 17-bit address bus (A0–A16) interface directly with LVTTL logic without level translation.
Designed for noise-sensitive systems, it uses JEDEC-standard center power/ground pin placement (VDD on Pin 25 & 28, GND on Pin 14 & 20) to minimize simultaneous switching noise. The device guarantees tAA = 15 ns, tRC = 15 ns, and tWC = 15 ns across –40°C to +85°C with single 3.3 V supply operation.
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) | 15 ns max at VDD = 3.15–3.6 V and TA = –40°C to +85°C; determines minimum address-to-data valid delay in read cycles |
| Read Cycle Time (tRC) | 15 ns max; defines shortest interval between successive read operations on same address |
| Supply Voltage | 3.15 V to 3.6 V; compatible with standard 3.3 V LVTTL rails; no 5 V tolerance |

| I/O0–I/O7 | Bidirectional Data Bus | 8-bit tristatable data path; direction controlled by WE and OE; LVTTL-compatible voltage levels |
| CS | Chip Select | Active-low enable; places device in active or high-Z state; used with OE for partial-cycle gating |
| OE | Output Enable | Active-low control for output drivers only; allows read data to appear without deselecting chip |
| WE | Write Enable | Active-low write strobe; latches data on I/O bus when CS is low; supports WE- or CS-controlled timing |
| VDD (Pins 25, 28) | Power Supply | 3.3 V core supply; dual pins reduce IR drop and improve decoupling effectiveness |
| GND (Pins 14, 20) | Ground Reference | Return path for all signals; dual pins minimize ground bounce in high-speed switching |

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-45ZSXI | 128K × 8-bit, 45 ns access, 2.5 V/3.3 V dual-supply; SOJ-32 package; no center-GND pinout | Slower timing limits use in sub-20 ns bus cycles; wider voltage range adds flexibility in mixed-rail designs | Select when lower cost and broader supply tolerance outweigh speed and noise-performance requirements |

FAQ
What is the maximum guaranteed access time for the 71V124SA15TYGI8 under industrial temperature conditions?
The 71V124SA15TYGI8 guarantees tAA ≤ 15 ns and tRC ≤ 15 ns across the full industrial temperature range of –40°C to +85°C at VDD = 3.15 V to 3.6 V. This specification is production-tested per Renesas datasheet Table 08 and applies to both read and write cycle timing under worst-case voltage and temperature conditions.
Does the 71V124SA15TYGI8 require a refresh circuit or clock signal to retain data?
No, the 71V124SA15TYGI8 is a fully static RAM and requires no refresh cycles or clock inputs. Data retention relies solely on stable DC power; as long as VDD remains within 3.15–3.6 V and temperature stays within –40°C to +85°C, stored bits persist indefinitely without external timing signals.
Which package type and footprint does the 71V124SA15TYGI8 use?
The 71V124SA15TYGI8 uses a 32-pin plastic SOJ (Small Outline J-lead) package with 300-mil body width (PJG32). Its pinout follows JEDEC standard MO-089AB, featuring center-placed VDD (Pins 25, 28) and GND (Pins 14, 20) for reduced switching noise.
Can the 71V124SA15TYGI8 operate with a 5 V interface?
No, the 71V124SA15TYGI8 is strictly a 3.3 V device. Its absolute maximum input voltage is VDD + 0.5 V (≤ 4.1 V), and VIH min is 2.0 V - incompatible with standard 5 V TTL logic levels. Interfacing with 5 V systems requires level translation circuitry.
What is the standby current consumption of the 71V124SA15TYGI8 in full deselected mode?
In full standby mode (CS = VIH, no address or data activity), the 71V124SA15TYGI8 draws ISB1 ≤ 10 µA maximum at VDD = 3.6 V and TA = +85°C. This static current enables ultra-low-power retention in battery-backed or energy-constrained applications without sacrificing wake-up responsiveness.
