Product details
Overview
The 6116SA25TPGI from Renesas Electronics is a 16K-bit (2K × 8) high-speed CMOS static RAM with 25ns maximum access time, industrial temperature range (–40°C to +85°C), TTL-compatible I/O, and 5V ±10% supply operation. It features automatic standby mode on chip select high, low-power operation (40mA active, 40mA standby for SA version), and plastic 24-pin DIP packaging - used in embedded controllers, data acquisition systems, and legacy industrial PLCs requiring non-refresh volatile memory.
For engineers reviewing the 6116SA25TPGI datasheet, 6116SA25TPGI pinout, 6116SA25TPGI application, or 6116SA25TPGI equivalent, key selection considerations include verified 25ns read cycle timing (tRC), industrial-grade reliability under sustained thermal stress, DC leakage current ≤5µA at VCC max, and compatibility with legacy 5V TTL bus architectures without level translation.
Technical Context
This device implements fully static asynchronous logic with no clocks or refresh required. Its address decoder drives a 128×128 memory array, and control circuitry enforces strict timing for CS/WE/OE coordination during read and write cycles - including tWC (write cycle time) of 25ns and tAA (address access time) of 25ns.
Input and output buffers are designed for direct TTL interfacing (VIH = 2.2V min, VOL = 0.4V max at 8mA), and the standby power mode reduces ICC2 to 40mA when CS is high. The SA variant uses standard power CMOS process, distinguishing it from LA's sub-1µW retention capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16,384 bits (2K × 8 organization) - supports byte-wide data buses without external multiplexing |
| Access Time | 25ns max (tAA and tRC) - enables reliable operation in 40MHz bus systems with setup/hold margin |
| Supply Voltage | 5.0V ±10% - compatible with standard 5V TTL logic rails; no external regulation required |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including factory automation and motor control cabinets |
| Power Consumption | ICC1 = 100mA max (active), ISB = 40mA max (TTL-level standby) - enables thermal management in dense PCB layouts |
| I/O Compatibility | TTL-input and TTL-output levels - eliminates need for level shifters in legacy 5V microcontroller interfaces |
| Package | 24-pin plastic DIP (PTG24, 300-mil width) - supports through-hole assembly and socket-based prototyping |
Pinout & Package
Package: 24-pin plastic dual in-line package (PTG24), 300-mil width, through-hole mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit address bus supporting 2K-word addressing; latched internally on CS/WE transitions |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit TTL-compatible data path; high-impedance state when CS high or OE/WE inactive |
| CS | Chip Select | Active-low enable; forces device into standby (ISB = 40mA) when high, enabling system-level power gating |
| WE | Write Enable | Active-low control for write cycles; must overlap low CS to initiate valid write (tWP = 25ns min) |
| OE | Output Enable | Active-low control for read output drivers; decouples data bus when high to prevent contention |
| VCC | Power Supply | +5V ±10% main supply; powers core logic and I/O buffers simultaneously |
| GND | Ground Reference | Common return for all internal circuits and I/O; requires low-inductance connection for noise immunity |
Key Features
| Feature | Design Value |

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, 2K × 8, 5V, industrial temp, but uses different pinout (SOIC only) and has higher ISB (50mA vs 40mA) | Requires PCB redesign for SOIC footprint; not drop-in for PTG24 DIP layout | Select if board space is constrained and SOIC assembly is already standardized |
| IS61LV25616AL-25MLI | 25ns, 256K × 16, 3.3V core - incompatible voltage and density; requires level translation and bus width adaptation | Suitable only for 3.3V systems with wider data paths; not a functional substitute without redesign | Consider only for new designs migrating to 3.3V architecture with increased memory depth needs |
Compared with AS6C1008-25ZIN and IS61LV25616AL-25MLI, the 6116SA25TPGI offers verified through-hole DIP compatibility, exact 5V TTL signaling, and industrial qualification without voltage translation - making it the sole option for maintaining legacy 5V DIP-based systems with unchanged layout and BOM.

FAQ
What is the maximum operating frequency supported by the 6116SA25TPGI?
The 6116SA25TPGI does not operate on a clock signal - it is a fully static RAM. Its maximum usable bus frequency is determined by its 25ns read cycle time (tRC), supporting up to 40MHz asynchronous operation when interfaced with controllers that meet setup/hold timing. No internal oscillator or clock input exists; timing is governed solely by external address and control signal edges.
Does the 6116SA25TPGI require refresh circuitry or external clock signals?
No, the 6116SA25TPGI requires neither refresh circuitry nor external clocks. As a static RAM, it retains data indefinitely as long as power is applied and CS remains low during access. This eliminates refresh overhead and timing complexity found in DRAM, making it ideal for simple microcontroller systems and real-time control applications where deterministic latency is essential.
Is the 6116SA25TPGI pin-compatible with other 6116-series variants such as the LA version or military-grade models?
Yes, the 6116SA25TPGI shares identical pinout and function mapping with all 6116SA/LA variants in the same package type (PTG24), including 6116LA25TPGI. Differences lie in power consumption (LA offers µW-level retention), timing margins, and temperature grading - but address, data, and control pin assignments are fully consistent across SA/LA and commercial/industrial/military versions in 24-pin DIP.
What is the data retention capability of the 6116SA25TPGI during power loss?
The 6116SA25TPGI does not support low-voltage data retention. Unlike the LA variant, which guarantees data hold at 2V, the SA version requires full 5V ±10% supply for reliable operation. Below VCC min (4.5V), data integrity is not assured - retention functionality is exclusive to LA-grade parts and is not implemented in the 6116SA25TPGI.
Can the 6116SA25TPGI be used in place of older IDT-branded 6116SRAMs?
Yes, the 6116SA25TPGI is the Renesas rebranded successor to the IDT6116SA25TPGI, with identical electrical specifications, timing, pinout, and packaging. Renesas acquired IDT's memory business and maintains full backward compatibility - no design changes, layout modifications, or firmware updates are needed when substituting IDT-labeled units with current Renesas 6116SA25TPGI stock.
