Product details
Overview
6116SA20SOG8 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 operation (–40°C to +85°C). It features static asynchronous operation (no clock or refresh), low-power standby mode (40 mA typical ICC2), and 24-pin SOIC packaging - used in legacy embedded controllers, instrumentation buffers, and real-time data acquisition systems where deterministic timing and nonvolatile backup compatibility are required.
For engineers reviewing the 6116SA20SOG8 datasheet, 6116SA20SOG8 pinout, 6116SA20SOG8 application, or 6116SA20SOG8 equivalent, this page delivers verified specifications including AC/DC timing parameters, standby current behavior, TTL-level interface compliance, package dimensions, and direct alternatives for drop-in replacement or power-optimized redesign.
Technical Context
The 6116SA20SOG8 implements fully static memory architecture with asynchronous read/write control via independent CS, WE, and OE inputs. Its address decoding supports 11-bit addressing (A0–A10) for 2K-word selection, and I/O bidirectionality is managed through three-state output drivers controlled by chip select and output enable logic.
It operates at VCC = 5.0 V ±10%, with guaranteed VIH ≥ 2.2 V and VIL ≤ 0.8 V, ensuring robust noise margin against TTL logic families. Standby current drops to 40 mA (ICC2) under active cycling and further to 2 mA (ISB1) in full CMOS-level standby when CS > VHC and inputs held valid.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 8-bit (16,384 bits), enabling byte-wide data bus interfacing without external multiplexing |
| Access Time (tAA) | 20 ns max (commercial grade), defining minimum address-to-data-valid delay in read cycles |
| Supply Voltage | 5.0 V ±10%, compatible with standard TTL/CMOS 5V system rails and legacy power domains |

Pinout & Package
6116SA20SOG8 is housed in a 24-pin Small Outline Integrated Circuit (SOIC) package with 300-mil body width and gull-wing leads (JEDEC MS-012AC). Pin pitch is 0.050 inch (1.27 mm), and lead finish is lead-free per RoHS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| WE | Write Enable | Active-low signal initiating write cycle; combined with CS LOW to define write window per timing diagram |
| OE | Output Enable | Active-low control for output drivers only; does not affect write operations or internal memory state |
| VCC | Power Supply | +5 V supply rail; decoupling capacitor (0.1 µF) required within 1 cm of pin for stable AC operation |

FAQ
What is the maximum access time specified for the 6116SA20SOG8?
The 6116SA20SOG8 has a maximum access time (tAA) of 20 ns under commercial temperature conditions (0°C to +70°C) and VCC = 5.0 V ±10%. This value is guaranteed across all operating voltages and temperatures within its industrial grade specification (–40°C to +85°C), as confirmed in Renesas' AC Electrical Characteristics table on page 6 of the July 2020 datasheet. The 6116SA20SOG8 maintains this timing without derating in industrial environments.
Does the 6116SA20SOG8 require a refresh clock or external timing circuitry?
No, the 6116SA20SOG8 is a fully static RAM and requires no refresh clock or external timing signals. Its internal circuitry sustains data indefinitely as long as power is applied and CS remains active (LOW). This eliminates the need for refresh controllers, simplifying system design and guaranteeing consistent read/write latency - a key advantage over DRAM in real-time embedded applications using the 6116SA20SOG8.
What package type and pin count does the 6116SA20SOG8 use?
The 6116SA20SOG8 uses a 24-pin Small Outline Integrated Circuit (SOIC) package with gull-wing leads (package code PSG24), 300-mil body width, and 1.27 mm pitch. This matches JEDEC MS-012AC mechanical dimensions and is compatible with standard surface-mount reflow profiles. The pinout is identical across all 24-pin variants of the IDT6116SA/LA family, including the 6116SA20SOG8.
Is the 6116SA20SOG8 compliant with RoHS and green manufacturing standards?
Yes, the 6116SA20SOG8 is a green, RoHS-compliant device per EU Directive 2011/65/EU, as documented in Renesas' July 2020 datasheet revision. It features lead-free terminations and halogen-free molding compound. The "G" suffix in the part number explicitly denotes green packaging, and the device carries no restricted substances above threshold limits - critical for medical and industrial certifications requiring the 6116SA20SOG8.
Can the 6116SA20SOG8 interface directly with TTL logic families?
Yes, the 6116SA20SOG8 features fully TTL-compatible inputs and outputs: VIH(min) = 2.2 V, VIL(max) = 0.8 V, VOH(min) = 2.4 V (at IOH = –4 mA), and VOL(max) = 0.4 V (at IOL = 8 mA). These values meet or exceed standard 74LS and 74F logic thresholds, allowing direct connection without level shifters - a verified design feature confirmed in the DC Electrical Characteristics tables (pages 3–4) of the 6116SA20SOG8 datasheet.
