Product details
Overview
6116SA15SOG from Renesas Electronics is a 16K-bit (2K × 8) high-speed CMOS static RAM with 15 ns maximum access time, TTL-compatible I/O, and industrial-grade SOIC-24 packaging. It operates at 5.0 V ±10%, supports standby power mode via chip select, and delivers reliable non-refresh operation in commercial temperature range (0°C to +70°C). Used in legacy embedded controllers and instrumentation where deterministic timing and low system-level power are critical.
For engineers reviewing the 6116SA15SOG datasheet, 6116SA15SOG pinout, 6116SA15SOG application, or 6116SA15SOG equivalent, this page provides verified electrical specs, functional timing behavior, package footprint details, real-world use cases, and validated alternative parts for design continuity and supply assurance.
Technical Context
The 6116SA15SOG implements fully static asynchronous logic with no clocks or refresh cycles required. Its address decoding and I/O control circuitry enable single-cycle read/write operations using independent CS, OE, and WE signals - supporting both CS-controlled and WE-controlled write protocols per JEDEC-standard SRAM timing conventions.
It features dual power modes: active operation with ICC1 = 105 mA (max) at f = 0 and full standby (CMOS-level CS deassertion) drawing only 2 mA (max), enabling significant board-level power savings. Input leakage is ≤5 µA, output leakage ≤2 µA, and data retention is not supported - distinguishing it from LA-series variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 8-bit (16,384 bits), byte-wide parallel interface |
| Access Time (tAA) | 15 ns max - guarantees worst-case read latency under commercial conditions (VCC = 4.5–5.5 V, TA = 0°C to +70°C) |
| Supply Voltage | 5.0 V ±10% - compatible with standard TTL/CMOS logic rails; no regulation required beyond ±0.5 V tolerance |
| Operating Current (ICC1) | 105 mA max - defines peak dynamic supply draw during continuous read/write at zero frequency |
| Standby Current (ISB1) | 2 mA max - achieved only when CS > VHC (CMOS-high threshold), enabling ultra-low quiescent power in sleep states |
| I/O Compatibility | TTL-compatible inputs and outputs - interfaces directly with 74LS/74ALS without level-shifting |
| Temperature Range | Commercial: 0°C to +70°C - validated across full voltage and timing spec range per Renesas datasheet Rev. Jul.17.20 |
Pinout & Package
6116SA15SOG is supplied in a 24-pin gull-wing SOIC (PSG24) package, 300-mil body width, with standard 0.050″ lead pitch and JEDEC MS-012AC outline. Pin 1 is marked by beveled corner or dot; pin numbering follows counterclockwise convention from top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit address bus selecting one of 2K memory locations; latched on CS or WE transition depending on cycle type |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel data path; high-impedance when CS HIGH or during write setup/hold windows |
| CS | Chip Select | Active-low enable; drives device into standby (ISB1 = 2 mA) when HIGH, enables memory access when LOW |
| OE | Output Enable | Active-low control for read data assertion; must be LOW during valid read cycles, HIGH during writes to avoid bus contention |
| WE | Write Enable | Active-low signal initiating write; combined with CS LOW to define write window per tWC and tAW timing constraints |
| VCC | Power Supply | +5 V ±10% main supply; decoupling capacitor (0.1 µF) recommended adjacent to pin |
| GND | Ground Reference | Signal and power return; requires low-inductance connection to minimize noise coupling into sensitive I/O paths |
Key Features
| Feature | Design Value |
|---|---|
| No refresh required | Enables deterministic real-time systems without hidden CPU overhead or DRAM controller complexity |
| 15 ns access time | Supports CPU bus cycles up to ~66 MHz in zero-wait-state configurations with proper address setup |
| TTL-compatible I/O | Eliminates need for external level translators when interfacing with legacy microcontrollers (e.g., Z80, 8085, 68000) |
| CMOS process with low soft-error rate | Reduces single-event upsets in radiation-prone environments such as aerospace avionics or industrial PLCs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS6C1008-15TIN | 15 ns access, 2K × 8, 5 V, SOIC-24, but rated for industrial temp (–40°C to +85°C) | Supports wider ambient range; suitable for upgraded designs requiring extended thermal margin | Select when operating environment exceeds +70°C or long-term reliability at temperature extremes is required |
| IS61LV256AL-15TI | 15 ns, 32K × 8 (256 Kbit), 3.3 V core, SOIC-28 - not pin-compatible; requires voltage translation and layout change | Higher density and lower voltage; intended for modern 3.3 V systems with space-constrained layouts | Choose only if migrating to 3.3 V architecture and redesigning PCB footprint and power delivery |
Compared with AS6C1008-15TIN, 6116SA15SOG offers identical speed and pinout but lacks industrial temperature qualification; compared with IS61LV256AL-15TI, it uses 5 V logic and occupies smaller SOIC-24 footprint, making it preferable for legacy 5 V board refreshes without voltage rail changes.

FAQ
What is the maximum operating temperature for the 6116SA15SOG?
The 6116SA15SOG is specified for commercial temperature range only: 0°C to +70°C. This is confirmed in the Renesas datasheet Rev. Jul.17.20 under "Recommended Operating Temperature and Supply Voltage" and "Orderable Part Information", where "C" grade denotes commercial grade. Operation outside this range may result in timing violations or increased leakage current. The 6116SA15SOG does not support industrial or military temperature grades.
Does the 6116SA15SOG support battery backup or data retention mode?
No, the 6116SA15SOG does not support battery backup or low-voltage data retention. That capability is exclusive to the LA-series variants (e.g., 6116LA20SOG), which specify 2 V data retention voltage and microamp-level retention current. The 6116SA15SOG datasheet contains no data retention characteristics - its ISB1 standby current drops to 2 mA only when CS is driven above VHC, not at reduced VCC.
Is the 6116SA15SOG pin-compatible with other 6116-series variants?
Yes, all 6116SA/LA variants in SOIC-24 (PSG24) packaging share identical pinout and footprint, including 6116SA15SOG, 6116SA20SOG, and 6116LA25SOGI. This allows speed- or power-grade upgrades without PCB revision. However, LA variants require attention to VCC derating for retention mode - the 6116SA15SOG itself operates strictly at 5.0 V ±10% with no low-VCC operation.
What is the minimum write pulse width (tWP) required for reliable operation of the 6116SA15SOG?
The minimum write pulse width (tWP) for the 6116SA15SOG is 15 ns, as specified in the AC Electrical Characteristics table for 15 ns speed grade under "Write Cycle No. 1 (WE Controlled Timing)". This value is guaranteed across the commercial temperature range and 5.0 V ±10% supply. Shorter pulses risk incomplete write cycles and data corruption, especially under worst-case voltage and temperature corners.
Can the 6116SA15SOG be used with a 3.3 V microcontroller interface?
No - the 6116SA15SOG is a 5 V-only device with TTL-compatible thresholds (VIH = 2.2 V min, VIL = 0.8 V max) and absolute maximum VTERM of +7.0 V. Direct connection to 3.3 V logic risks violating input voltage limits and causing excessive input leakage or latch-up. Level translation (e.g., TXB0108 or discrete MOSFET buffers) is mandatory for safe interoperability with 3.3 V systems.
