Product details
Overview
6116SA15SOG8 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 temperature operation (–40°C to +85°C). It features static asynchronous operation-no clocks or refresh required-and low-power standby mode activated by chip select (CS), enabling system-level power savings in embedded controllers and data acquisition systems.
For engineers reviewing the 6116SA15SOG8 datasheet, 6116SA15SOG8 pinout, 6116SA15SOG8 application, or 6116SA15SOG8 equivalent, key selection criteria include guaranteed 15 ns read cycle time at 5.0 V ±10%, CMOS-level standby current of 2 mA (ICC2), SOIC-24 gull-wing packaging, and compatibility with legacy 6116-family board layouts requiring 2K × 8 SRAM with TTL signaling.
Technical Context
The 6116SA15SOG8 implements fully static asynchronous memory architecture with independent address decoding, I/O control, and TTL-compatible input thresholds (VIH = 2.2 V min, VIL = 0.8 V max). Its operation relies solely on CS, OE, and WE control signals-no clock or refresh circuitry is integrated.
It supports two distinct power modes: active operation with ICC1 = 105 mA (max) at f = 0 and full standby with ISB1 = 2 mA (max) when CS > VHC and inputs held at valid logic levels. Data retention capability is not supported-this is the SA (standard power) variant, not the LA (low-power/battery-retention) version.
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 at VCC = 4.5–5.5 V, TA = –40°C to +85°C - enables 66.7 MHz burst read throughput |
| Supply Voltage | 5.0 V ±10% (4.5–5.5 V) - compatible with standard TTL/CMOS 5 V systems |
| Operating Current (ICC1) | 105 mA max - defines worst-case active power draw for thermal design |
| Standby Current (ISB1) | 2 mA max at CMOS-level CS deassertion - enables low-quiescent power sleep states |
| I/O Compatibility | TTL-input and TTL-output - direct interfacing with 74LS/74F logic without level shifters |
| Temperature Range | –40°C to +85°C - qualified for industrial environments including motor drives and PLCs |
Pinout & Package
6116SA15SOG8 is housed in a 24-pin SOIC (gull-wing) package (package code PSG24), 300-mil body width, JEDEC MS-012AC compliant. Pin pitch is 1.27 mm; package footprint matches industry-standard 24-lead SOIC layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit address bus selecting one of 2K memory locations |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit parallel data path; high-impedance when CS or OE inactive |
| CS | Chip Select | Active-low enable; forces device into standby (ISB1 = 2 mA) when HIGH |
| OE | Output Enable | Active-low control for data output drivers; does not affect write operations |
| WE | Write Enable | Active-low signal initiating write cycle; latches data on falling edge with CS LOW |
| VCC | Power Supply | +5 V supply pin; must be decoupled locally per high-speed SRAM layout guidelines |
| GND | Ground Reference | Signal and power return; requires low-inductance connection to minimize noise |
Key Features
| Feature | Design Value |
|---|---|
| 15 ns maximum access time | Enables real-time response in microcontroller-based instrumentation where sub-20 ns memory latency is critical |
| Static asynchronous operation | Eliminates need for external refresh circuitry or clock generation-reduces BOM count and layout complexity |
| TTL-compatible I/O | Direct interface with legacy 74-series logic and microprocessor buses without translation components |
| Industrial temperature range (–40°C to +85°C) | Validated operation across extended ambient conditions typical of factory automation and outdoor electronics |

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 - same speed and organization but manufactured by Alliance Memory | Qualified for commercial temp only (0°C to +70°C); lacks industrial grade rating | Select when cost sensitivity outweighs extended temperature requirement and board requalification is feasible |
| IS61LV256AL-15TI | 15 ns access, 32K × 8 (256 Kbit), 3.3 V core - higher density and lower voltage, not pin-compatible | Requires level translation for 5 V systems; larger memory map changes firmware addressing | Choose only if migrating to 3.3 V architecture and needing >2K capacity; not a drop-in replacement |
Compared with AS6C1008-15TIN, 6116SA15SOG8 offers verified industrial temperature support and Renesas' long-term supply commitment; versus IS61LV256AL-15TI, it provides true 5 V TTL compatibility and legacy pinout fidelity at the cost of lower density.

FAQ
What is the maximum operating frequency supported by the 6116SA15SOG8?
The 6116SA15SOG8 does not operate on a clock; its performance is defined by access and cycle times. With a 15 ns maximum access time (tAA) and 25 ns read cycle time (tRC), it supports effective burst read rates up to 40 MHz. System-level throughput depends on bus protocol overhead, not an internal clock domain.
Does the 6116SA15SOG8 support battery backup or data retention mode?
No, the 6116SA15SOG8 is the SA (standard power) variant and does not support battery backup or low-voltage data retention. That functionality is exclusive to LA-series parts like 6116LA20SOG8. The 6116SA15SOG8 requires continuous 5 V supply for data integrity.
Is the 6116SA15SOG8 pin-compatible with older 6116-series SRAMs from IDT or other manufacturers?
Yes, the 6116SA15SOG8 maintains full pin-to-pin and functional compatibility with the original IDT6116SA family and second-source 6116 SRAMs in SOIC-24 packages. Address, data, and control pin assignments match JEDEC-standard 24-pin SRAM layouts.
What are the DC input voltage thresholds for reliable operation of the 6116SA15SOG8?
The 6116SA15SOG8 specifies VIH ≥ 2.2 V (min) and VIL ≤ 0.8 V (max) at VCC = 4.5–5.5 V. These TTL-compatible thresholds ensure robust interfacing with 74LS, 74F, and microcontroller GPIOs without external biasing or Schmitt triggers.
Can the 6116SA15SOG8 be used in a 3.3 V system?
No-the 6116SA15SOG8 is strictly a 5 V device with absolute maximum VCC of 5.5 V and minimum operating VCC of 4.5 V. Applying 3.3 V will result in undefined behavior, failed reads/writes, and potential data corruption. Use 3.3 V–compatible SRAMs such as IS61LV256AL for lower-voltage designs.
