Product details
Overview
6116LA20SOGI8 from Renesas Electronics is a 16K-bit (2K × 8) low-power CMOS static RAM with 20 ns access time, industrial temperature range (–40°C to +85°C), 5 V supply, and SOIC-24 package. It supports TTL-compatible I/O, battery backup data retention at 2 V, and automatic standby mode when chip select is high - used in embedded controllers, instrumentation, and legacy industrial memory subsystems.
For engineers reviewing the 6116LA20SOGI8 datasheet, 6116LA20SOGI8 pinout, 6116LA20SOGI8 application, or 6116LA20SOGI8 equivalent, key selection criteria include guaranteed 20 ns read cycle time across industrial temperatures, sub-1 µA full-standby current, 2 V data retention capability, and SOIC-24 footprint compatibility with legacy 6116 designs requiring extended thermal reliability.
Technical Context
This device implements fully static asynchronous operation with no clocks or refresh required. Its control logic uses CS/WE/OE three-state decoding to manage read, write, and high-impedance modes - enabling direct interface with microcontrollers and bus-based systems without external timing generation.
The LA variant integrates optimized CMOS design for ultra-low standby power: ISB1 = 0.1 mA (typ.) at CMOS-level chip deselect, and ICCDR ≤ 0.5 µA (typ.) during 2 V battery retention. All inputs meet TTL voltage thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V) and exhibit ≤ 8 pF input capacitance.
Key Specifications

|---|---|
| Memory Organization | 2K × 8-bit (16,384 bits), byte-wide parallel interface |
| Access Time (tAA) | 20 ns max at VCC = 5.0 V ±10%, TA = –40°C to +85°C - ensures deterministic timing in real-time control loops |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V logic rails and tolerant of board-level ripple |
| Data Retention Voltage | 2.0 V min - enables long-term data hold using coin-cell or backup battery without regulator |
| Full Standby Current (ISB1) | 0.1 mA typ. at VCC = 5.5 V, CMOS-level CS deassertion - reduces system sleep power by >95% vs SA variant |

FAQ
What is the maximum guaranteed access time for 6116LA20SOGI8 across its full industrial temperature range?
The 6116LA20SOGI8 has a maximum guaranteed access time (tAA) of 20 ns at VCC = 5.0 V ±10% and TA = –40°C to +85°C. This value is production-tested and specified in the AC Electrical Characteristics table under industrial grade conditions - ensuring deterministic timing for real-time firmware execution without margining.
Does 6116LA20SOGI8 support true battery backup operation, and what voltage range is validated?
Yes, the 6116LA20SOGI8 supports true battery backup: data retention is guaranteed down to VCC = 2.0 V, with ICCDR ≤ 0.5 µA (typ.) at that voltage. This is exclusive to the LA version and verified per the Data Retention Characteristics table - enabling reliable long-term storage using standard 2–3 V coin cells without external regulators.
Is 6116LA20SOGI8 pin-compatible with other 6116 variants such as 6116SA20SOGI8?
Yes, 6116LA20SOGI8 is pin-compatible with all 6116SA/LA variants in the same SOIC-24 (PSG24) package, including 6116SA20SOGI8. The pinout, footprint, and signal definitions match exactly - only electrical parameters (e.g., ISB1, ICCDR, tAA consistency over temperature) differ between SA and LA versions.
What is the full-standby current (ISB1) specification for 6116LA20SOGI8, and how is it triggered?
The full-standby current ISB1 for 6116LA20SOGI8 is 0.1 mA (typ.) and 0.9 mA (max) at VCC = 5.5 V, TA = +25°C. It is triggered when CS is driven above VHC (VCC – 0.2 V), and all inputs are held below VLC (0.2 V) or above VHC - placing the device in deepest power-down mode with I/O in high-Z and internal circuitry minimized.
Can 6116LA20SOGI8 be used in new designs, or is it obsolete?
The 6116LA20SOGI8 remains actively supported by Renesas for legacy and sustaining engineering use. While not recommended for *new* high-volume consumer designs due to density limitations, it is fully qualified for industrial, medical, and aerospace applications where long-term supply, proven reliability, and backward compatibility are prioritized over cutting-edge specs.
