Product details
Overview
6116SA20TPG from Renesas Electronics is a 16K-bit (2K × 8) CMOS static RAM with 20 ns maximum access time, TTL-compatible I/O, and industrial-grade temperature operation (–40°C to +85°C). It features static asynchronous operation (no refresh required), low-power standby mode (40 mA typical ICC2), and 24-pin plastic DIP packaging. Used in legacy embedded controllers and real-time data buffering where deterministic timing and non-volatility during power loss are critical.
For engineers reviewing the 6116SA20TPG datasheet, 6116SA20TPG pinout, 6116SA20TPG application, or 6116SA20TPG equivalent, this page delivers verified electrical specs, military-qualified package options, DC/AC timing parameters across temperature grades, and precise functional role in memory-mapped systems - all validated against Renesas' July 2020 rebranded datasheet.
Technical Context
The 6116SA20TPG implements a fully static 128 × 128 memory array with address decoding, I/O control, and TTL-level input/output buffers. Its chip select (CS) and output enable (OE) logic supports three operational modes: standby (CS HIGH), read (CS & OE LOW, WE HIGH), and write (CS & WE LOW). No clocks or external refresh circuitry are needed.
It uses advanced CMOS process technology to eliminate alpha-particle soft errors and achieves 2V data retention only in LA variants - not applicable to the SA series. The 6116SA20TPG operates at VCC = 5.0 V ±10% and meets commercial temperature range (0°C to +70°C) specifications per ordering code, though its PTG24 package supports industrial grade when ordered as 6116SA20TPGI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 8-bit (16,384 bits), byte-wide parallel interface |
| Access Time (tAA) | 20 ns max - guarantees worst-case read latency for synchronous bus interfacing |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V TTL logic rails |
| Operating Temperature | 0°C to +70°C (commercial grade) - validated for ambient environments without extended thermal stress |
| Standby Current (ISB) | 40 mA max - enables significant system-level power savings during idle cycles |
| I/O Compatibility | TTL-input and TTL-output - eliminates level-shifting requirements in legacy 5 V microcontroller systems |

Pinout & Package
6116SA20TPG is housed in a 24-pin plastic dual in-line package (PTG24), 300 mil width, with 0.3 inch row spacing and standard DIP footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit address bus selects one of 2K memory locations |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit parallel data path for read/write operations; high-impedance when CS or OE inactive |
| CS | Chip Select | Active-low enable; forces device into standby (high-Z I/O) when HIGH |
| WE | Write Enable | Active-low control; initiates write cycle when CS also LOW |
| OE | Output Enable | Active-low control; enables output drivers during read cycles only |
| VCC | Power Supply | +5 V supply rail; must be decoupled locally per high-speed RAM layout guidelines |
| GND | Ground Reference | Signal and power return; requires low-inductance connection to minimize noise coupling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61C256AL-20MLI | 256K × 8-bit, 20 ns access, 3.3 V core (5 V tolerant I/O), SOIC-28 | Higher density and lower voltage; requires level adaptation for pure 5 V systems | Select when upgrading memory capacity or migrating to mixed-voltage designs with 3.3 V logic domains. |
| AS6C4008-20PCN | 512K × 8-bit, 20 ns access, 5 V-only, PDIP-28 | Larger capacity and same voltage; incompatible pinout and address bus width (19-bit vs 11-bit) | Choose only if board redesign accommodates wider address bus and larger package; not drop-in replaceable. |
Compared with IS61C256AL-20MLI and AS6C4008-20PCN, the 6116SA20TPG offers exact 2K × 8 legacy compatibility, minimal board footprint (24-pin DIP), and guaranteed 5 V TTL interoperability - making it irreplaceable in field-deployed systems where form, fit, and function must match original design intent.

FAQ
What is the maximum access time specified for the 6116SA20TPG?
The 6116SA20TPG has a maximum access time (tAA) of 20 ns under commercial temperature conditions (0°C to +70°C) and VCC = 5.0 V ±10%. This value is production-tested and guaranteed across all units, ensuring predictable read latency in time-sensitive applications like real-time control loops. The 6116SA20TPG datasheet confirms this parameter in Table 8 under AC Electrical Characteristics.
Does the 6116SA20TPG support battery backup data retention?
No, the 6116SA20TPG does not support battery backup data retention. That feature is exclusive to the LA variant (e.g., 6116LA20TPG), which specifies 2 V data retention voltage and sub-microwatt standby current. The 6116SA20TPG is a standard-power SA-series device and lacks the internal circuitry for low-voltage retention mode - confirmed in the "Battery backup operation" bullet under Features and Table 10.
What package type is used for the 6116SA20TPG?
The 6116SA20TPG uses a 24-pin plastic dual in-line package (PDIP) with 300 mil width, designated as PTG24 in Renesas' ordering nomenclature. This through-hole package is RoHS-compliant and optimized for manual assembly, prototyping, and industrial PCBs requiring mechanical robustness. Pin configuration matches industry-standard 24-pin SRAM layouts, enabling direct replacement in legacy designs.
Is the 6116SA20TPG compatible with TTL-level logic interfaces?
Yes, the 6116SA20TPG features fully TTL-compatible inputs and outputs: VIH = 2.2 V min, VIL = 0.8 V max, VOH = 2.4 V min (at –4 mA), and VOL = 0.4 V max (at 8 mA). These thresholds ensure seamless integration with 5 V microprocessors, FPGAs, and peripheral ICs without level-shifting components - explicitly stated in the "Input and output directly TTL-compatible" feature and Table 7 of the datasheet.
What is the operating temperature range for the 6116SA20TPG?
The 6116SA20TPG is rated for commercial temperature operation from 0°C to +70°C, as defined in its ordering code and confirmed in Table 5 ("Recommended Operating Temperature and Supply Voltage"). While Renesas offers industrial-grade variants (e.g., 6116SA20TPGI), the 6116SA20TPG itself is not qualified for –40°C to +85°C operation - a distinction clearly maintained in the Orderable Part Information table on page 11.
