Product details
Overview
The 6116SA35SOG from Renesas Electronics is a 16K-bit (2K × 8) high-speed CMOS static RAM with 35ns maximum access time, TTL-compatible I/O, and industrial temperature support (–40°C to +85°C). It features low-power standby mode (40mA typical ICC2), full static operation (no refresh required), and is packaged in 24-pin SOIC (PSG24) for high-density PCB layouts. Used in legacy industrial controllers and embedded systems requiring nonvolatile data retention via external battery backup.
For engineers reviewing the 6116SA35SOG datasheet, 6116SA35SOG pinout, 6116SA35SOG application, or 6116SA35SOG equivalent, key selection criteria include verified 35ns read cycle time (tRC), CS-controlled standby current (ISB = 40mA max), industrial-grade operating temperature range, and compatibility with 5V ±10% supply and TTL-level logic interfaces.
Technical Context
This device implements fully static asynchronous memory architecture with no clocks or refresh circuitry. Address decoding is performed by internal 128×128 memory array control, and data I/O is bidirectional with three-state outputs enabled by OE and controlled by CS/WE logic states.
It supports two primary operational modes: active read/write (CS = LOW, WE/OE configured per Truth Table) and TTL-level standby (CS = HIGH, ISB ≤ 40mA). The 6116SA35SOG does not support battery-backed data retention - that capability is exclusive to LA-series variants (e.g., 6116LA35SOG).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16,384 bits (2K × 8 organization), enabling byte-wide data bus interfacing without external multiplexing. |
| Access Time (tAA) | 35ns max (industrial grade), defining minimum address-to-valid-data delay in read cycles. |
| Supply Voltage | 5.0V ±10%, compatible with standard TTL and early microprocessor bus voltage tolerances. |
| Operating Temperature | –40°C to +85°C, qualified for industrial environments including factory automation and instrumentation. |
| Standby Current (ISB) | 40mA max (TTL-level CS HIGH), enabling system-level power savings during idle periods. |
| I/O Compatibility | TTL-input and TTL-output compatible (VIH = 2.2V min, VOH = 2.4V min at –4mA), ensuring direct interface with 74LS/ALS logic families. |
| Package | 24-pin SOIC (PSG24, gull-wing), 300-mil width, supporting surface-mount assembly and board density optimization. |
Pinout & Package
24-pin SOIC (PSG24) package with gull-wing leads, 300-mil body width, JEDEC MS-012AC compliant.
| 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 | Bidirectional Data Bus | 8-bit parallel data path; direction controlled by WE and OE signals per truth table. |
| CS | Chip Select | Active-low enable; when HIGH, forces outputs to high-impedance and enters standby mode. |
| WE | Write Enable | Active-low control signal determining write (LOW) vs. read (HIGH) operation during CS = LOW. |
| OE | Output Enable | Active-low gate for output drivers; must be LOW for valid read data on I/O lines. |
| VCC | Power Supply | +5V ±10% main supply; powers core logic and I/O buffers. |
| GND | Ground Reference | Signal and power return plane; decoupling capacitor placement critical near this pin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 6116SA25SOG | 25ns max access time (10ns faster), same package, voltage, and temperature rating. | Suitable where tighter timing margins are required in high-speed CPU bus interfaces. | Select when system timing budget allows margin for future speed upgrades or clock frequency increases. |
| 6116LA35SOG | Same 35ns speed but LA variant offers 2V data retention and <1µA ISB1 in full CMOS standby. | Required only if battery-backed data hold during main power loss is mandatory. | Choose only if data retention during AC failure is a functional requirement - 6116SA35SOG lacks this feature. |
Compared with 6116SA25SOG, the 6116SA35SOG trades 10ns speed for broader availability and lower cost in industrial-qualified SOIC; compared with 6116LA35SOG, it omits battery-retention circuitry, reducing complexity and cost where backup is unnecessary.

FAQ
What is the maximum access time specified for the 6116SA35SOG?
The 6116SA35SOG has a maximum access time (tAA) of 35ns across its rated industrial temperature range (–40°C to +85°C) at VCC = 5.0V ±10%. This value is guaranteed per the AC Electrical Characteristics table and applies to address-to-valid-output timing in read cycles with CS and OE asserted.
Does the 6116SA35SOG support battery-backed data retention?
No, the 6116SA35SOG does not support battery-backed data retention. That capability is exclusive to the LA-series variants (e.g., 6116LA35SOG), which specify 2V data retention voltage and sub-microwatt standby current. The 6116SA35SOG is a standard-power SA variant with ISB = 40mA max in TTL-level standby mode.
What package type is used for the 6116SA35SOG?
The 6116SA35SOG uses a 24-pin SOIC package with gull-wing leads (package code PSG24), 300-mil body width, and JEDEC MS-012AC compliance. It is lead-free and RoHS-compliant per Renesas' Green Parts initiative.
Is the 6116SA35SOG compatible with TTL-level logic interfaces?
Yes, the 6116SA35SOG features fully TTL-compatible inputs and outputs: VIH(min) = 2.2V, VIL(max) = 0.8V, VOH(min) = 2.4V at –4mA, and VOL(max) = 0.4V at 8mA. This allows direct connection to 74LS, 74ALS, and other 5V TTL families without level shifters.
What is the operating temperature range for the 6116SA35SOG?
The 6116SA35SOG is rated for industrial temperature operation from –40°C to +85°C. This is confirmed in the Recommended Operating Conditions table and supported by qualification testing per industry standards for industrial-grade components.
