Product details
Overview
6116SA25SOGI8 from Renesas Electronics is a 16K-bit (2K × 8) high-speed CMOS static RAM with 25ns maximum access time, industrial temperature range (–40°C to +85°C), TTL-compatible I/O, and 24-pin SOIC packaging. It operates at 5.0V ±10%, supports standby power mode via chip select, and is used in embedded controllers, instrumentation, and legacy industrial systems requiring non-refreshed memory.
For engineers reviewing the 6116SA25SOGI8 datasheet, 6116SA25SOGI8 pinout, 6116SA25SOGI8 application, or 6116SA25SOGI8 equivalent, key selection criteria include guaranteed 25ns read cycle time, industrial-grade reliability, SOIC-24 footprint compatibility, low standby current (2mA typical), and direct TTL-level interfacing without level-shifting.
Technical Context
This device implements fully static asynchronous operation-no clocks or refresh cycles required-and uses CMOS technology to eliminate alpha-particle soft errors. Its control logic relies on three active-low signals: CS (chip select), WE (write enable), and OE (output enable), enabling precise read/write timing control across multiple access modes including read, write, and high-impedance standby.
The memory array is organized as 128 × 128 bits with integrated address decoder and I/O control circuitry. Input leakage current is ≤5µA (industrial grade), output drive capability is ±4mA/±8mA, and data retention voltage is not applicable (LA version only), confirming this is the standard-power SA variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16,384 bits (2K × 8), supporting byte-wide data bus interfaces without external multiplexing. |
| Access Time | 25ns max (industrial temp), defining minimum time between address valid and stable data output during read cycles. |
| Supply Voltage | 5.0V ±10% (4.5V–5.5V), compatible with legacy 5V TTL logic families and eliminating need for voltage regulators. |
| Operating Temperature | –40°C to +85°C, validated for use in industrial control panels, motor drives, and factory automation equipment. |
| Standby Current | 2mA max (ISB1, CMOS-level CS), enabling significant system-level power savings when deselected. |
| I/O Compatibility | TTL-compatible inputs and outputs, allowing direct connection to 74LS/74HC logic without interface buffers. |
| Package | 24-pin SOIC (PSG24), gull-wing lead form with 0.600-inch width, suitable for automated PCB assembly and space-constrained layouts. |
Pinout & Package
6116SA25SOGI8 is housed in a 24-pin Small Outline Integrated Circuit (SOIC) package with gull-wing leads (package code PSG24), 0.600-inch body width, and JEDEC MS-012AC compliant dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit address bus accepting binary values to select one of 2048 memory locations. |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit parallel interface handling both read data output and write data input under OE/WE control. |
| CS | Chip Select | Active-low enable that places device in standby (high-Z I/O) when deasserted, reducing system power. |
| WE | Write Enable | Active-low signal initiating write cycle; combined with CS LOW to latch data into selected location. |
| OE | Output Enable | Active-low control for read operations; enables output drivers only when CS and OE are both LOW. |
| VCC | Power Supply | +5V supply pin requiring local 0.1µF ceramic decoupling to suppress switching noise. |
| GND | Ground Reference | Signal and power ground return path; must be connected to low-impedance system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Static Operation | No clock or refresh circuitry required-simplifies system design and eliminates dynamic power overhead and timing constraints. |
| TTL Compatibility | Direct interface with standard 5V TTL logic families avoids level-shifter components and reduces BOM count. |
| Low Standby Power | 2mA max ISB1 current at CMOS-level CS deassertion enables energy-efficient idle states in battery-backed or fanless systems. |
| Industrial Temp Rating | Validated operation from –40°C to +85°C ensures reliability in harsh environments like factory floors and outdoor enclosures. |
| Soft-Error Immunity | CMOS process minimizes alpha-particle-induced bit flips-critical for long-term data integrity in unattended systems. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS6C1008-25ZIN | 25ns access, 2K × 8, 5V, SOIC-24, but rated –40°C to +85°C with 3mA ISB1 vs. 2mA for 6116SA25SOGI8. | Same industrial temperature and package; slightly higher standby current may impact ultra-low-power designs. | Select if AS6C1008-25ZIN offers better distributor availability or longer production lifecycle. |
| IS61LV25616AL-25MLI | 25ns, 256K × 16, 3.3V-only, TSSOP-44-larger density, different voltage, incompatible pinout and bus width. | Not drop-in; requires PCB redesign, level translation, and firmware adaptation for 16-bit wide access. | Choose only when migrating to higher-density, lower-voltage architecture with full system redesign. |
Compared with AS6C1008-25ZIN, 6116SA25SOGI8 offers lower standby current and proven field reliability in legacy 5V systems; versus IS61LV25616AL-25MLI, it provides true pin-compatible replacement for existing 2K × 8, 5V designs without layout or voltage rail changes.

FAQ
What is the maximum operating frequency supported by the 6116SA25SOGI8?
The 6116SA25SOGI8 does not operate on a clock; it is an asynchronous SRAM. Its 25ns access time corresponds to a maximum effective cycle rate of ~40 MHz in read-only continuous addressing, but actual system throughput depends on bus protocol, CS/OE/WE timing margins, and controller interface design. The device guarantees tRC (read cycle time) ≤25ns across the full industrial temperature range.
Does the 6116SA25SOGI8 support battery backup operation?
No, the 6116SA25SOGI8 is the standard-power SA variant and does not support battery backup data retention. Battery backup capability (2V VDR, µW-level retention current) is exclusive to LA-series parts such as 6116LA25SOGI8. Using 6116SA25SOGI8 in battery-retention circuits will result in data loss below VCC = 4.5V.
Is the 6116SA25SOGI8 pin-compatible with other 24-pin SOIC SRAMs like the HM6116 or CY62167?
No-while all are 2K × 8 SRAMs in 24-pin SOIC, pinouts differ significantly. The 6116SA25SOGI8 follows the industry-standard 6116 pinout (A0–A10, I/O0–I/O7, CS, WE, OE, VCC, GND), whereas HM6116 uses different pin assignments for WE/OE, and CY62167 is a 32K × 8 device with incompatible address/data mapping. Always verify pinout against the 6116SA25SOGI8 datasheet before substitution.
What is the meaning of 'SOGI8' in the part number 6116SA25SOGI8?
In 6116SA25SOGI8, 'SO' denotes Small Outline package, 'G' indicates gull-wing leads, 'I' specifies Industrial temperature grade (–40°C to +85°C), and '8' signifies tape-and-reel packaging (8mm carrier tape, 2000 units per reel). This distinguishes it from tube-packaged variants like 6116SA25SOGI.
Can the 6116SA25SOGI8 be used in new designs given its legacy status?
Yes-the 6116SA25SOGI8 remains actively manufactured and supported by Renesas for legacy system maintenance and long-lifecycle industrial applications. While newer low-voltage or higher-density alternatives exist, 6116SA25SOGI8 is appropriate for designs requiring 5V TTL compatibility, proven reliability, and unchanged PCB footprints. Aetrix Electronics provides full lifecycle coordination for sustained supply.
