Product details
Overview
6116SA20SOG from Renesas Electronics is a 16K-bit (2K × 8) high-speed CMOS static RAM with 20 ns maximum access time, TTL-compatible I/O, and industrial-grade temperature operation (–40°C to +85°C). It features low-power standby mode (40 mA typical ICC2), full static operation (no refresh required), and is packaged in 24-pin SOIC for high-density PCB layouts. Used in legacy embedded controllers and real-time data buffering where deterministic timing and non-volatility during power loss are critical.
For engineers reviewing the 6116SA20SOG datasheet, 6116SA20SOG pinout, 6116SA20SOG application, or 6116SA20SOG equivalent, this page delivers verified electrical specs, functional timing behavior, package-validated pin roles, and direct alternative part comparisons - all grounded in Renesas' official 6116SA/LA datasheet (Rev. Jul.17.20).
Technical Context
The 6116SA20SOG implements fully static asynchronous architecture with no clocks or refresh cycles. Its address decoder drives a 128 × 128 memory array, and control logic responds to independent CS, OE, and WE signals to manage read/write/standby states. Input and output buffers are designed for direct TTL-level interfacing without level-shifting.
It supports two distinct power modes: active operation (ICC1 = 100 mA max at VCC = 5.5 V) and TTL-level standby (ISB = 40 mA max), plus CMOS-level deep standby (ISB1 = 2 mA max). Data retention is not supported - only the LA variant offers 2V battery backup; the SA variant is strictly active-only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 8-bit (16,384 bits), byte-wide parallel interface |
| Access Time (tAA) | 20 ns max - guarantees data valid within 20 ns after address stabilization under commercial conditions |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V TTL logic rails |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments without derating |
| Standby Current (ISB) | 40 mA max - reduces system power when CS is deasserted (TTL-level input threshold) |
| Input/Output Compatibility | TTL-compatible - VIH = 2.2 V min, VIL = 0.8 V max, eliminates need for external level translators |
| Package | 24-pin SOIC (PSG24), gull-wing lead form, 300-mil width - surface-mountable with JEDEC MS-012AC footprint |
Pinout & Package
6116SA20SOG is supplied in a 24-pin Small Outline Integrated Circuit (SOIC) package with gull-wing leads (package code PSG24), 300-mil body width, compliant with JEDEC MS-012AC. Pin numbering follows standard SOIC top-view convention, with Pin 1 marked by notch or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit address bus selecting one of 2048 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 (ISB) when HIGH |
| WE | Write Enable | Active-low control; initiates write cycle when CS and WE both LOW |
| OE | Output Enable | Active-low control; enables output drivers only during read cycles |
| VCC | Power Supply | +5 V supply pin; must be decoupled locally per high-speed RAM layout guidelines |
| GND | Ground Reference | Signal and power return; requires low-inductance connection to minimize noise coupling |

Use Scenario: Real-time I/O scanning in programmable logic controllers where sensor data must be captured and held between scan cycles without CPU intervention. IC Role / Device Role / Timing Role: Byte-wide static RAM providing deterministic 20 ns read/write access for dual-port-like burst transfers via shared address/data bus. Use Value: Eliminates need for refresh arbitration logic and ensures data coherency across multiple interrupt service routines operating on the same memory block. |
Use Scenario: Adding external RAM to 8-bit microcontrollers (e.g., Intel 8051, Zilog Z8) with limited on-chip memory for firmware stack or temporary variable storage. IC Role / Device Role / Timing Role: Asynchronous parallel memory mapped at fixed address range; controlled via discrete CS, OE, and WE lines from MCU address decode logic. Use Value: Enables execution of larger control algorithms without modifying core MCU architecture - leverages existing 5 V TTL bus timing margins. |
| Avionics Maintenance Terminal | Test Equipment Firmware Cache |
|
Use Scenario: Portable diagnostic tools used in aircraft maintenance requiring reliable short-term data logging during ground checks under wide ambient temperature swings. IC Role / Device Role / Timing Role: Non-refreshing memory buffer storing flight parameter snapshots prior to upload; operates across –40°C to +85°C without thermal derating. Use Value: Guarantees consistent 20 ns access latency regardless of cabin temperature - avoids timing violations during cold-soak or hot-soak testing. |
Use Scenario: Automated test equipment (ATE) storing calibration coefficients and test pattern sequences in volatile memory between power cycles. IC Role / Device Role / Timing Role: High-speed SRAM acting as fast-access cache for FPGA-based pattern generators, minimizing wait states during vector streaming. Use Value: Reduces pattern generation latency by 15–20 ns per memory fetch compared to slower alternatives - directly improves test throughput. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS6C1008-20TIN | 20 ns access, 5 V, 2K × 8, 24-pin SOIC - identical speed and organization but uses advanced low-power CMOS (0.5 µA ISB1) | Supports deeper sleep (0.5 µA vs. 2 mA) but lacks MIL-STD-883 qualification; not rated for extended industrial temp extremes | Select for ultra-low-power portable instruments where standby current dominates battery life - verify thermal derating above +70°C. |
| IS61LV256AL-20TI | 20 ns access, 3.3 V only, 32K × 8 (256 Kbit), 28-pin SOIC - higher density and lower voltage, but incompatible VCC and pinout | Requires level translation and board redesign; suited for 3.3 V systems upgrading from 6116-class devices | Choose only when migrating to 3.3 V architecture and needing >2× memory capacity - not drop-in replaceable. |
Compared with AS6C1008-20TIN and IS61LV256AL-20TI, the 6116SA20SOG provides guaranteed industrial temperature operation and TTL-level compatibility without voltage translation, making it uniquely suitable for maintaining legacy 5 V designs under harsh environmental conditions - despite higher standby current than modern alternatives.

FAQ
What is the maximum operating temperature range for the 6116SA20SOG?
The 6116SA20SOG is rated for industrial temperature operation from –40°C to +85°C. This specification is confirmed in Renesas' official datasheet (Rev. Jul.17.20), Table "Recommended Operating Temperature and Supply Voltage", where the "Industrial" grade explicitly lists that range. It is not qualified for military (–55°C to +125°C) or extended commercial (0°C to +70°C only) grades.
Does the 6116SA20SOG support battery backup or data retention mode?
No, the 6116SA20SOG does not support battery backup or low-voltage data retention. Only the LA variant (e.g., 6116LA20SOG) specifies 2 V data retention capability and microamp-level retention current. The SA variant - including 6116SA20SOG - is designed for active-only operation and enters full standby (ISB = 40 mA) when CS is HIGH, with no retention functionality.
Is the 6116SA20SOG pin-compatible with other 2K × 8 SRAMs like the HM6116 or CY6116?
Yes, the 6116SA20SOG maintains functional pin compatibility with industry-standard 24-pin 2K × 8 SRAMs including HM6116 and CY6116. Pin assignments for A0–A10, I/O0–I/O7, CS, WE, OE, VCC, and GND match the JEDEC-standard 24-pin DIP/SOIC layout. However, timing parameters (e.g., tAA, tWC) and DC characteristics (e.g., ISB, VIH) differ - verify timing margins in your design.
What package type is used for the 6116SA20SOG, and what is its lead count?
The 6116SA20SOG uses a 24-pin Small Outline Integrated Circuit (SOIC) package with gull-wing leads, designated PSG24 in Renesas' ordering information. It has exactly 24 terminals: 11 address inputs, 8 bidirectional data lines, 3 control signals (CS, WE, OE), plus VCC and GND - matching the standard 2K × 8 SRAM pinout.
Can the 6116SA20SOG operate reliably at 4.5 V supply voltage?
Yes, the 6116SA20SOG is fully specified to operate at VCC = 4.5 V minimum, as stated in the "DC Electrical Characteristics" table (VCC Min. = 4.5 V). All AC and DC parameters - including 20 ns access time, VIH/VIL thresholds, and ISB current - are guaranteed across the full 4.5 V to 5.5 V range, enabling robust operation even under brown-out conditions.
