Product details
Overview
6116LA25SOG from Renesas Electronics is a 16K-bit (2K × 8) low-power CMOS static RAM with 25ns maximum access time, TTL-compatible I/O, and battery backup data retention down to 2V. It operates across commercial temperature range (0°C to +70°C), uses no refresh or clocks, and is packaged in 24-pin SOIC for high-density board layouts-ideal for legacy embedded controllers and memory-buffered instrumentation.
For engineers reviewing the 6116LA25SOG datasheet, 6116LA25SOG pinout, 6116LA25SOG application, or 6116LA25SOG equivalent, key selection criteria include standby current (≤0.1mA at CMOS-level chip select), data retention capability at 2V, industrial-grade SOIC packaging compatibility, and verified 25ns read/write timing under VCC = 5.0V ±10%.
Technical Context
This device implements fully static asynchronous operation using high-reliability CMOS technology, eliminating alpha-particle soft-error susceptibility. Its control logic supports three distinct operational modes-standby (CS HIGH), read (CS & OE LOW, WE HIGH), and write (CS & WE LOW)-with bidirectional I/O pins and TTL-level input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V).
Timing behavior is defined by guaranteed AC parameters including tRC = 25ns (read cycle time), tWC = 25ns (write cycle time), and tCDR = 0ns (chip deselect to data retention entry). The LA variant's ultra-low ISB1 (full standby current) of 0.1mA enables extended battery-backed operation without external power management circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS6C1008-25ZIN | 25ns access, 5V-only, 2.5V data retention not supported | Lacks battery backup capability; higher ISB (2µA vs. 0.1µA) | Select when full 5V operation is guaranteed and backup retention is unnecessary |
| IS61LV25616AL-25MLI | 3.3V core, 25ns, 2.2V data retention, 44-pin TSOP | Lower voltage, larger package, higher density (512K×16) | Select for modern 3.3V systems requiring higher capacity and smaller pitch than SOIC allows |

FAQ
What is the maximum operating temperature range for the 6116LA25SOG?
The 6116LA25SOG is rated for commercial temperature operation from 0°C to +70°C. It is not specified for industrial (–40°C to +85°C) or military (–55°C to +125°C) ranges-those grades require different orderable part numbers such as 6116LA25SOGI or 6116LA25TDB. Always verify ambient thermal conditions against this grade's specification before deployment.
Does the 6116LA25SOG require external refresh circuitry?
No, the 6116LA25SOG is a fully static RAM and requires no clocks or refresh cycles. Its internal CMOS latches retain data indefinitely as long as VCC remains within specification and CS is asserted appropriately. This eliminates timing-critical refresh overhead in microcontroller or FPGA-based systems.
What is the minimum supply voltage needed to retain data in the 6116LA25SOG?
The 6116LA25SOG guarantees data retention down to 2.0V (VDR = 2.0V), as confirmed in the Data Retention Characteristics table. At this voltage, typical retention current is 0.5µA, enabling multi-year operation from a single CR2032 coin cell-provided all other inputs (CS, A0–A10, etc.) are held at valid logic levels.
Can the 6116LA25SOG be used with 3.3V microcontrollers?
The 6116LA25SOG is strictly a 5V device: its VIH minimum is 2.2V and VIL maximum is 0.8V, but VCC must be 5.0V ±10%. Direct connection to 3.3V logic risks violating input voltage limits and may cause undefined behavior. Level-shifting circuitry is required for interoperability with 3.3V controllers.
What package type does the 6116LA25SOG use, and is it RoHS-compliant?
The 6116LA25SOG uses a 24-pin SOIC package with gull-wing leads (JEDEC MS-012AC, package code PSG24). Per Renesas' ordering information and "Green" designation in the datasheet revision history, this part is RoHS-compliant and restricted-substance-free, meeting lead-free soldering requirements for modern assembly processes.
