Product details
Overview
6116LA20SOGI from Renesas Electronics is a 16K-bit (2K × 8) low-power CMOS static RAM with 20 ns access time, industrial temperature range (–40°C to +85°C), TTL-compatible I/O, and 2V data retention capability. It operates at 5.0 V ±10%, consumes ≤95 mA active current and only 0.1 µA in full standby mode, and is used in battery-backed memory subsystems for embedded controllers and instrumentation.
For engineers reviewing the 6116LA20SOGI datasheet, 6116LA20SOGI pinout, 6116LA20SOGI application, or 6116LA20SOGI equivalent, this page delivers verified timing specs (tAA = 20 ns, tRC = 20 ns), power modes (TTL/CMOS standby), retention voltage (2.0 V), package (24-pin SOIC), and industrial-grade reliability per MIL-STD-883 Class B compliance.
Technical Context
The 6116LA20SOGI implements fully static asynchronous operation-no clocks or refresh required-and uses high-reliability CMOS process to eliminate alpha-particle soft errors. Its control logic supports three distinct operational states: active read/write (CS = L, WE/OE controlled), TTL-level standby (CS = H, ISB = 35 mA), and CMOS-level full standby (CS > VHC, ISB1 = 0.1 µA).
Address decoding is internal (11-bit A0–A10), data path is bidirectional (I/O0–I/O7), and all inputs meet VIH ≥ 2.2 V / VIL ≤ 0.8 V at VCC = 5.0 V. The device guarantees data retention down to 2.0 V across –40°C to +85°C, with leakage currents limited to |ILI| ≤ 2 µA and |ILO| ≤ 2 µA under worst-case conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16,384 bits (2,048 × 8), enabling byte-wide data storage without external multiplexing |
| Access Time (tAA) | 20 ns max - defines minimum address-to-valid-data delay in read cycles |
| Supply Voltage | 5.0 V ±10% - compatible with standard TTL/CMOS logic rails and legacy 5 V systems |
| Data Retention Voltage | 2.0 V min - allows backup from coin-cell batteries during main power loss |
| Standby Current (ISB1) | 0.1 µA max at CMOS-level chip select - enables multi-year battery life in always-on monitoring nodes |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including factory automation and outdoor telemetry |
| Input/Output Compatibility | TTL-compatible - interfaces directly with 74LS, 74F, and microcontroller GPIO without level shifters |
Pinout & Package
6116LA20SOGI is housed in a 24-pin gull-wing SOIC (PSG24) package, 300-mil width, RoHS-compliant and green-certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit binary address bus selecting one of 2,048 memory locations |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface supporting simultaneous read or write of one byte |
| CS | Chip Select | Active-low enable; drives device into TTL standby (ISB) when HIGH, full standby (ISB1) when above VHC |
| WE | Write Enable | Active-low control for write operations; latches data on falling edge when CS is LOW |
| OE | Output Enable | Active-low gate for output drivers; enables read data only when CS and OE are LOW |
| VCC | Power Supply | +5 V supply pin; must be decoupled locally to suppress switching noise |
| GND | Ground Reference | Signal and power return; requires low-impedance connection to minimize ground bounce |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXI | 32M-bit (4M × 8), 45 ns access, 3.3 V core, 5 V tolerant I/O | Higher density and lower voltage; not pin-compatible; requires PCB redesign | Select for new 3.3 V designs needing larger memory footprint and modern low-power architecture |
| AS6C1008-20TIN | 1M-bit (128K × 8), 20 ns access, 5 V, industrial temp, same 24-pin SOIC | Lower density, identical speed/package/temp but no 2V retention or MIL-STD-883 compliance | Choose when retention and military qualification are unnecessary and cost is primary constraint |
Compared with CY62167EV30LL-45ZSXI and AS6C1008-20TIN, the 6116LA20SOGI uniquely combines industrial temperature rating, MIL-STD-883 Class B reliability, 2V data retention, and 20 ns performance in a legacy 5 V SOIC footprint-making it irreplaceable for sustaining existing battery-backed industrial and avionics systems.

FAQ
What is the maximum guaranteed access time for 6116LA20SOGI?
The 6116LA20SOGI has a maximum guaranteed access time (tAA) of 20 ns across its rated industrial temperature range (–40°C to +85°C) and supply voltage (5.0 V ±10%). This value is production-tested and specified in the AC Electrical Characteristics table under "Read Cycle No. 1" with CS and OE asserted. The 20 ns rating applies strictly to the LA version in SOIC packaging at industrial grade - not to SA variants or military grades.
Does 6116LA20SOGI support true data retention at 2.0 V?
Yes, the 6116LA20SOGI guarantees data retention at VCC = 2.0 V minimum across its full industrial temperature range, as confirmed in the "Data Retention Characteristics" table (VDR = 2.0 V). This feature is exclusive to LA versions and enables operation from backup batteries or supercapacitors during main power failure, with ICCDR ≤ 1.5 µA at 2.0 V and 25°C.
What is the standby current consumption of 6116LA20SOGI in full CMOS standby mode?
In full CMOS standby mode (CS > VHC, VIN < VLC or VIN > VHC), the 6116LA20SOGI draws a maximum of 0.1 µA (ISB1), as specified in Table 8. This ultra-low current enables multi-year battery life in always-on monitoring applications. Note that TTL-level standby (CS > VIH) draws up to 35 mA - users must drive CS above VHC (not just VIH) to achieve sub-microamp operation.
Is 6116LA20SOGI pin-compatible with other 6116-series SRAMs?
Yes, the 6116LA20SOGI shares identical 24-pin SOIC (PSG24) pinout and signal mapping with all IDT/Renesas 6116SA/LA variants, including 6116SA20SOGI and 6116LA25SOGI. Address (A0–A10), data (I/O0–I/O7), and control (CS, WE, OE, VCC, GND) pins are functionally and physically aligned - allowing direct substitution within the same speed/temperature grade without layout changes.
What qualification standards does 6116LA20SOGI meet?
The 6116LA20SOGI complies with MIL-STD-883 Class B for mechanical and environmental testing, including thermal cycling, vibration, and hermeticity. It also meets Renesas' green manufacturing standards (lead-free, halogen-free) and is rated for industrial temperature operation (–40°C to +85°C). These qualifications are documented in the Ordering Information and Absolute Maximum Ratings sections of the Renesas datasheet Rev. Jul.17.20.
