Product details
Overview
6116LA15SOGI8 from Renesas Electronics is a 16K-bit (2K × 8) low-power CMOS static RAM with 15 ns access time, industrial temperature range (–40°C to +85°C), TTL-compatible I/O, and battery backup data retention at 2V. It operates without clocks or refresh and supports standby power mode via chip select control - used in embedded controllers, instrumentation, and legacy industrial systems requiring nonvolatile SRAM hold.
For engineers reviewing the 6116LA15SOGI8 datasheet, 6116LA15SOGI8 pinout, 6116LA15SOGI8 application, or 6116LA15SOGI8 equivalent, key selection criteria include guaranteed 15 ns read cycle time, 0.1 µA full-standby current, 2V data retention capability, SOIC-24 package compatibility, and industrial-grade reliability per MIL-STD-883 Class B compliance for critical timing and memory retention use cases.
Technical Context
The 6116LA15SOGI8 implements fully static asynchronous operation using high-reliability CMOS technology, eliminating alpha-particle soft-error susceptibility. Its address decoder and I/O control circuitry enable direct TTL-level interfacing without level-shifting.
Chip select (CS) drives automatic entry into TTL-level standby (ISB = 35 mA max) or CMOS-level full-standby (ISB1 = 0.1 µA typ) modes. Data retention at 2V is exclusive to the LA variant and validated across –40°C to +85°C, with tCDR = 0 ns and ICCDR ≤ 30 µA.
Key Specifications

|---|---|---|
| A0–A10 | Address Inputs | 11-bit address bus accepting 0–2047 for 2K-word addressing |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit TTL-compatible data path; high-impedance when CS or OE inactive |
| CS | Chip Select | Active-low enable; asserts full standby (ISB1) when driven above VHC (≈4.3 V) |
| OE | Output Enable | Active-low control for output drivers; allows read-only access while CS remains active |
| WE | Write Enable | Active-low write strobe; initiates write cycle on falling edge concurrent with CS low |
| VCC | Power Supply | +5 V supply input; decoupling capacitor required within 10 mm of pin |
| GND | Ground Reference | Signal and power return; must be connected to low-impedance ground plane |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV256AL-15KLI | 3.3 V supply only; 15 ns access; 256K × 8 organization; LVTTL I/O | Requires voltage translation in 5 V systems; larger capacity suits firmware caching but increases cost per bit | Select when migrating to 3.3 V platforms or needing >16K memory depth |
| AS6C4008-15PCN | 5 V supply; 15 ns access; 512K × 8; commercial temp only (0°C to +70°C); no 2V retention | Lacks industrial temp rating and battery backup - unsuitable for unregulated or battery-backed systems | Choose for cost-sensitive 5 V consumer applications where extended temperature and retention are not required |
Compared with IS61LV256AL-15KLI and AS6C4008-15PCN, the 6116LA15SOGI8 uniquely delivers 2V data retention, industrial temperature support, and pin-compatible SOIC-24 packaging in a legacy 5V ecosystem - making it irreplaceable for maintaining existing designs requiring robust, low-power SRAM hold.

FAQ
What is the maximum guaranteed access time for the 6116LA15SOGI8?
The 6116LA15SOGI8 has a maximum guaranteed access time of 15 ns across its full industrial temperature range (–40°C to +85°C) and supply voltage (4.5 V to 5.5 V). This value is production-tested and specified in the AC Electrical Characteristics table under tAA and tRC parameters for the LA variant at 25 ns speed grade - confirming deterministic timing behavior for synchronous bus interfacing.
Does the 6116LA15SOGI8 support true battery backup operation?
Yes, the 6116LA15SOGI8 supports true battery backup operation with guaranteed data retention at 2.0 V minimum supply voltage. The LA version consumes ≤30 µA during retention (ICCDR), enabling multi-year hold on primary lithium cells. This function is exclusive to LA-series parts and verified across –40°C to +85°C per the Data Retention Characteristics table.
Is the 6116LA15SOGI8 pin-compatible with other 6116 variants?
Yes, the 6116LA15SOGI8 shares identical 24-pin SOIC pinout and signal definitions with all IDT/Renesas 6116SA/LA family members, including 6116SA15SOGI8 and 6116LA25SOGI8. Address, data, control, and power pins match exactly - allowing direct substitution where timing and temperature requirements align.
What is the full-standby current specification for the 6116LA15SOGI8?
The full-standby current (ISB1) for the 6116LA15SOGI8 is 0.1 µA typical and 0.9 µA maximum at VCC = 5.5 V, when CS is driven above VHC (≈4.3 V) and all inputs are held at valid CMOS levels. This ultra-low current enables decade-scale battery backup in always-on monitoring systems without compromising data integrity.
Which temperature grades are supported by the 6116LA15SOGI8?
The 6116LA15SOGI8 is rated for industrial temperature operation from –40°C to +85°C, as indicated by the "I" suffix in its orderable part number. It is not rated for commercial (0°C to +70°C) or military (–55°C to +125°C) grades - this specific variant is qualified exclusively for industrial applications per the Orderable Part Information table.
