Product details
Overview
The 6116SA15TPG from Renesas Electronics is a 16K-bit (2K × 8) high-speed CMOS static RAM with 15 ns maximum access time, TTL-compatible I/O, and commercial temperature range (0°C to +70°C). It operates at 5.0 V ±10%, supports static asynchronous operation without clocks or refresh, and uses a 24-pin plastic DIP (PTG24) package for legacy board-level integration in embedded controllers and instrumentation.
For engineers reviewing the 6116SA15TPG datasheet, 6116SA15TPG pinout, 6116SA15TPG application, or 6116SA15TPG equivalent, this page delivers verified timing parameters, DC/AC electrical characteristics, standby power behavior, military-grade reliability features, and direct substitution guidance - all aligned to Renesas' July 2020 rebranded specification.
Technical Context
This device implements fully static asynchronous memory architecture with three-state bidirectional data I/Os, independent chip select (CS), output enable (OE), and write enable (WE) controls. Its address decoding logic supports 11-bit addressing (A0–A10) and enables read/write cycles governed by tRC, tAA, tOE, and tWC timing constraints.
It features dual power modes: active operation with ICC1 = 105 mA (max) at 15 ns speed, and TTL-level standby (ISB = 40 mA max) or CMOS-level full standby (ISB1 = 2 mA max) when CS is deasserted. Input leakage (|ILI| ≤ 5 µA) and output leakage (|ILO| ≤ 5 µA) meet commercial-grade CMOS reliability targets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 8-bit (16,384 bits), enabling byte-wide data bus interfacing without external multiplexing |
| Access Time (tAA) | 15 ns max - defines minimum address-to-valid-data delay in read cycles under commercial conditions |
| Supply Voltage | 5.0 V ±10% - compatible with standard TTL/CMOS logic rails; no regulation required beyond ±0.5 V tolerance |
| Operating Temperature | 0°C to +70°C - validated for commercial-grade industrial control panels and test equipment |
| Standby Current (ISB1) | 2 mA max at CMOS-level CS deassertion - enables low-power hold mode during system sleep states |
| I/O Compatibility | TTL-compatible inputs and outputs - eliminates level-shifting circuitry when interfacing with 74LS/74HC families |
| Package Type | 24-pin plastic DIP (PTG24) - supports through-hole prototyping and legacy PCB assembly |
Pinout & Package
Package: 24-pin plastic DIP (PTG24), 300-mil width, through-hole mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit parallel address bus accepting 0–2047 row/column selection for 2K-word space |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit tristate I/O lines shared for read data output and write data input; high-impedance when CS or OE inactive |
| CS | Chip Select | Active-low enable controlling device activation; forces standby mode when HIGH, reducing ICC to ISB/ISB1 levels |
| OE | Output Enable | Active-low control for data output drivers; allows read operations while WE remains HIGH |
| WE | Write Enable | Active-low signal initiating write cycle; latches data on I/O lines when CS and WE are both LOW |
| VCC | Power Supply | +5 V supply rail; decoupling capacitor required near pin per layout best practices |
| GND | Ground Reference | Signal and power ground return path; must be low-impedance and star-connected for noise immunity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS6C1008-15PCN | 15 ns access, 5 V, 2K × 8, 28-pin SOJ - different pinout and package; higher ICC1 (120 mA) | SOJ footprint requires PCB redesign; not drop-in for PTG24 DIP layouts | Select only if migrating to surface-mount and accepting higher active current |
| IS61LV256AL-15KLI | 15 ns, 3.3 V supply, 32K × 8, 28-pin SOIC - incompatible voltage and density; no 5 V support | Requires level shifters and regulator changes; unsuitable for direct 5 V TTL systems | Use only in new 3.3 V designs where increased capacity justifies full redesign |
Compared with AS6C1008-15PCN and IS61LV256AL-15KLI, the 6116SA15TPG offers verified 5 V TTL compatibility, DIP packaging for legacy repair, and lower standby current - making it the sole viable choice for maintaining existing commercial-grade 5 V embedded systems without layout or voltage rail changes.

FAQ
What is the maximum operating frequency supported by the 6116SA15TPG?
The 6116SA15TPG does not operate on a clock; it is an asynchronous SRAM. Its maximum effective bandwidth is determined by its 15 ns access time, supporting read/write cycles up to approximately 66.7 MHz in ideal conditions. Real-world throughput depends on system-level timing margins including tRC (read cycle time), tWC (write cycle time), and bus contention - all specified in the Renesas datasheet Rev. Jul.17.20. The 6116SA15TPG achieves this performance without clocks or refresh circuitry.
Does the 6116SA15TPG support battery backup operation?
No, the 6116SA15TPG is the standard-power SA variant and does not support battery backup. Only the LA version (e.g., 6116LA20TPG) provides 2 V data retention capability. The 6116SA15TPG specifies ISB1 = 2 mA max in full standby but requires VCC ≥ 4.5 V for functional operation and data retention. For battery-backed applications, the 6116SA15TPG must be paired with external power-fail detection and hold circuitry.
Is the 6116SA15TPG pin-compatible with other 6116-series variants?
Yes, all 6116SA and 6116LA variants in the same package type (e.g., PTG24 DIP) share identical pinouts and footprints. The 6116SA15TPG is mechanically and electrically pin-compatible with 6116SA20TPG, 6116LA25TPG, and other PTG24-packaged members. Differences lie solely in speed grade, power profile, and temperature range - allowing drop-in replacement within the same package and grade family.
What are the absolute maximum ratings for VCC and operating temperature of the 6116SA15TPG?
The 6116SA15TPG has an absolute maximum VCC rating of –0.5 V to +7.0 V and an operating temperature range of 0°C to +70°C (commercial grade). Exceeding these limits risks permanent damage. Its recommended operating VCC is 5.0 V ±10% (4.5 V to 5.5 V), and it must remain within the commercial ambient range during functional operation. These values are confirmed in Renesas' Absolute Maximum Ratings table (Rev. Jul.17.20, Table 4).
Can the 6116SA15TPG be used in place of the original IDT6116SA15TPG?
Yes, the 6116SA15TPG is the Renesas-branded continuation of the IDT6116SA15TPG following Renesas' acquisition of IDT. Electrical specifications, pinout, timing, and packaging are identical per the July 2020 rebranded datasheet. Renesas explicitly states "Rebranded as Renesas datasheet" on page 11, confirming full functional and mechanical equivalence - making the 6116SA15TPG a direct, drop-in replacement for legacy IDT-sourced units.
