Product details
Overview
6116LA25SOGI8 from Renesas Electronics is a 16K-bit (2K × 8) low-power CMOS static RAM with 25ns access time, industrial temperature range (–40°C to +85°C), TTL-compatible I/O, and 2V data retention capability. It operates at 5.0V ±10%, consumes ≤85mA active current and only 0.1µA in full standby mode, and is used in battery-backed memory subsystems for embedded controllers and instrumentation.
For engineers reviewing the 6116LA25SOGI8 datasheet, 6116LA25SOGI8 pinout, 6116LA25SOGI8 application, or 6116LA25SOGI8 equivalent, key selection criteria include industrial-grade reliability, ultra-low standby power for extended battery life, guaranteed 25ns read cycle timing, SOIC-24 gull-wing packaging for high-density PCB layouts, and compatibility with legacy 6116-family address/data bus architectures.
Technical Context
The 6116LA25SOGI8 implements fully static asynchronous operation-no clocks or refresh required-and uses CMOS technology to eliminate alpha-particle soft errors. Its control logic supports three distinct operational modes: standby (CS HIGH), read (CS & OE LOW, WE HIGH), and write (CS & WE LOW).
It features dual standby power states: TTL-level standby (ISB = 40mA max) and CMOS-level full standby (ISB1 = 0.1µA typ), enabling system-level power optimization. Data retention at 2.0V is validated across the full industrial temperature range, with tCDR = 0ns and ICCDR ≤ 30µA at 3.0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 8-bit (16,384 bits), byte-wide parallel interface |
| Access Time (tAA) | 25ns max - guarantees deterministic read latency for real-time control loops |
| Supply Voltage | 5.0V ±10% - compatible with standard TTL/CMOS logic rails |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments without derating |
| Standby Current (ISB1) | 0.1µA typical at VCC = 5.5V - enables multi-year battery backup in portable systems |
| Data Retention Voltage | 2.0V min - maintains stored data during brown-out or main power loss |
| I/O Compatibility | TTL input thresholds (VIH = 2.2V, VIL = 0.8V) and output drive (VOH = 2.4V, VOL = 0.4V) |
Pinout & Package
6116LA25SOGI8 is housed in a 24-pin gull-wing SOIC (PSG24) package, 300-mil body width, RoHS-compliant and green-certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit address bus for 2K-word selection; latched on CS transition |
| 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; drives device into full standby (ISB1) when HIGH |
| OE | Output Enable | Active-low control for read data output; does not affect write operations |
| WE | Write Enable | Active-low signal initiating write cycle; overlaps with CS for valid write window |
| VCC | Power Supply | +5V supply pin; decoupling required within 10mm of pin per layout guidelines |

FAQ
What is the maximum operating frequency supported by the 6116LA25SOGI8?
The 6116LA25SOGI8 does not operate on a clock; it is an asynchronous SRAM. Its maximum effective throughput is governed by the 25ns access time (tAA), yielding a theoretical maximum read cycle rate of 40 MHz (1/25ns). Real-world sustained bandwidth depends on system bus protocol overhead and address setup/hold timing compliance.
Does the 6116LA25SOGI8 require external refresh circuitry?
No, the 6116LA25SOGI8 is a fully static RAM and requires no clocks or refresh cycles. Data remains valid indefinitely as long as VCC stays within specification and CS remains asserted during active use. This eliminates refresh controller design complexity and timing uncertainty in safety-critical systems.
Can the 6116LA25SOGI8 retain data when VCC drops below 5V?
Yes-the 6116LA25SOGI8 is explicitly rated for data retention down to 2.0V (VDR = 2.0V), making it suitable for battery-backup operation. At 2.0V, typical retention current is 30µA; full standby (ISB1) resumes only when CS rises above VHC (≈4.3V at VCC = 5.5V), ensuring clean retention entry/exit.
Is the 6116LA25SOGI8 pin-compatible with other 6116-series variants?
Yes-6116LA25SOGI8 shares identical 24-pin SOIC (PSG24) pinout and signal definitions with all IDT/Renesas 6116SA/LA family members, including 6116SA25SOGI8 and 6116LA20SOGI8. Functionally identical control timing and electrical specs allow direct substitution where speed and temperature grades align.
What is the meaning of the 'I8' suffix in 6116LA25SOGI8?
The 'I8' suffix denotes Industrial temperature grade (–40°C to +85°C) and tape-and-reel packaging (8mm carrier tape, 1000 units/reel). This distinguishes it from tube-packaged variants (e.g., 6116LA25SOGI) and commercial-grade parts (e.g., 6116LA25SOG), ensuring consistent automated assembly and environmental qualification.
