Product details
Overview
The 6116SA25SOG from Renesas Electronics is a 16K-bit (2K × 8) high-speed CMOS static RAM with 25ns maximum access time, TTL-compatible I/O, and industrial-grade temperature operation (–40°C to +85°C). It features low-power standby mode (40mA typical ICC2), full static operation (no refresh required), and is packaged in a 24-pin SOIC (PSG24) for high-density PCB layouts. It serves as main memory or buffer storage in legacy industrial controllers and embedded instrumentation.
For engineers reviewing the 6116SA25SOG datasheet, 6116SA25SOG pinout, 6116SA25SOG application, or 6116SA25SOG equivalent, key selection criteria include guaranteed 25ns read cycle time across commercial/industrial grades, CMOS-level standby current (2mA), TTL-compatible voltage thresholds (VIH = 2.2V min), and SOIC packaging compatibility with legacy 6116 footprint designs.
Technical Context
This device implements a fully static asynchronous architecture with no clocks or refresh circuitry. Its address decoder drives a 128 × 128 memory array, and control logic interprets CS, OE, and WE to manage read/write cycles and high-impedance I/O states. The chip select (CS) input enables automatic transition to low-power standby when deasserted.
It operates at 5.0V ±10% supply with TTL-compatible input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V) and delivers VOH ≥ 2.4V at –4mA and VOL ≤ 0.4V at 8mA. Data retention capability is not supported - only the LA variant offers 2V battery backup; the SA variant is standard-power only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16,384 bits (2K × 8), supporting byte-wide data bus interfacing without external demultiplexing. |
| Access Time | 25ns max (commercial & industrial grades), enabling reliable operation up to ~33 MHz system clock domains. |
| Supply Voltage | 4.5V–5.5V, compatible with standard 5V TTL/CMOS logic rails and legacy power supplies. |
| Standby Current | 40mA max (ISB), reducing system power during idle periods without requiring external power gating. |
| I/O Compatibility | TTL-compatible inputs and outputs, eliminating level-shifter requirements in mixed-logic systems. |
| Operating Temp | –40°C to +85°C (industrial grade), validated for use in factory automation and outdoor telemetry hardware. |
| Package | 24-pin SOIC (PSG24), gull-wing lead form with 0.6-inch body width, suitable for automated SMT assembly. |
Pinout & Package
6116SA25SOG is housed in a 24-pin Small Outline Integrated Circuit (SOIC) package with gull-wing leads (package code PSG24), 300-mil body width, and JEDEC MS-012AC compliant dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit address bus accepting 0–2047 to select one of 2K memory locations. |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit parallel interface supporting simultaneous read or write of one byte per cycle. |
| CS | Chip Select | Active-low enable: asserts memory access when LOW; forces high-impedance I/O and standby mode when HIGH. |
| WE | Write Enable | Active-low control: initiates write when LOW and CS is LOW; ignored during read cycles. |
| OE | Output Enable | Active-low control: enables output drivers during read; must be LOW for valid DATAOUT. |
| VCC | Power Supply | +5V supply pin; decoupling capacitor placement near this pin is critical for noise immunity. |
| GND | Ground Reference | 0V return path; requires low-inductance connection to minimize ground bounce during I/O transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Static Operation | No clocks or refresh cycles required - simplifies timing design and eliminates DRAM controller overhead. |
| TTL-Compatible I/O | Direct interface with 74LS/74HC logic families without level shifters or pull-up resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS6C1008-25ZIN | 25ns access, 5V, 2K × 8, SOIC-24, but uses advanced low-power CMOS (0.5µA ISB1 vs. 2mA for 6116SA25SOG). | Lower standby current suits battery-backed systems; lacks MIL-STD-883 qualified variants. | Select for ultra-low-power industrial edge nodes where data retention isn't required but sleep-mode current matters. |
| CY62167EV30LL-45ZSXIT | 45ns access, 3V/5V tolerant, SOIC-28, higher density (2M × 8), but slower and incompatible pinout. | Requires PCB redesign; suited for upgrade paths where speed penalty is acceptable for density gain. | Choose only if migrating legacy designs to higher capacity and can revise layout and timing margins. |
Compared with AS6C1008-25ZIN, the 6116SA25SOG offers higher standby current but broader temperature validation and direct legacy footprint compatibility; versus CY62167EV30LL-45ZSXIT, it provides faster access and pinout continuity at lower density - ideal for maintenance of installed base systems.

FAQ
What is the maximum operating temperature range for the 6116SA25SOG?
6116SA25SOG is rated for industrial temperature operation from –40°C to +85°C. This specification is validated per Renesas' datasheet revision Jul.17.20 and applies to all 6116SA25SOG orderable variants in SOIC packaging. It does not support military-grade (–55°C to +125°C) operation - that requires SD24 or CD24 ceramic DIP packages with "M" suffix.
Does the 6116SA25SOG support battery backup data retention?
No, the 6116SA25SOG does not support battery backup data retention. That feature is exclusive to the LA variant (e.g., 6116LA25SOG). The "SA" designation indicates Standard Power, and its data retention capability is not characterized - only the LA version guarantees 2V retention voltage and sub-1µA retention current.
Is the 6116SA25SOG pin-compatible with other 6116-series SRAMs?
Yes, the 6116SA25SOG shares identical pinout and function mapping with all 24-pin 6116-family devices including 6116SA15SOG, 6116SA20SOG, and 6116LA25SOG. All use the same PSG24 SOIC package and adhere to the standard 6116 pin configuration: A0–A10, I/O0–I/O7, CS, WE, OE, VCC, GND.
What is the minimum supply voltage required for reliable operation of the 6116SA25SOG?
The 6116SA25SOG requires a minimum supply voltage of 4.5V for guaranteed operation across its specified temperature range. Per DC Electrical Characteristics table (3089 tbl 06), VCC min is 4.5V at 5.0V nominal, and performance parameters like access time and output drive are only assured within 4.5V–5.5V. Operation below 4.5V may result in timing violations or data corruption.
Can the 6116SA25SOG be used in new designs despite its legacy status?
Yes, the 6116SA25SOG remains actively supported by Renesas and is suitable for new designs targeting long-lifecycle industrial equipment. While newer low-voltage SRAMs exist, this part is explicitly maintained for backward compatibility, with documented green (RoHS-compliant) status and ongoing production per ordering information tables in the Jul.17.20 datasheet.
