Product details
Overview
The 6116LA20TPG from Renesas Electronics is a 16K-bit (2K × 8) low-power CMOS static RAM with 20 ns access time, TTL-compatible I/O, and battery-backed data retention at 2 V. It operates across commercial temperature range (0°C to +70°C), uses asynchronous static architecture requiring no clocks or refresh, and is packaged in a 24-pin 300-mil plastic DIP for legacy embedded memory applications.
For engineers reviewing the 6116LA20TPG datasheet, 6116LA20TPG pinout, 6116LA20TPG application, or 6116LA20TPG equivalent, key selection criteria include its 20 ns read cycle time, 1 µW–4 µW standby power in battery-retention mode, 2 V data retention voltage, industrial-grade reliability via CMOS soft-error immunity, and compatibility with legacy 5 V TTL bus systems.
Technical Context
This device implements a fully static asynchronous memory array (128 × 128) with address decoding, I/O control, and TTL-level input/output buffers. Its chip-select–driven standby mode reduces ICC2 current to ≤35 mA during active operation and ISB to ≤0.1 mA under full CMOS-level standby (CS > VHC).
The 6116LA20TPG supports two distinct write timing modes - WE-controlled and CS-controlled - with guaranteed tWC (write cycle time) of 20 ns and tWP (write pulse width) of 15 ns. Data retention is validated down to 2.0 V across all temperature grades, exclusive to the LA variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

FAQ
What is the maximum guaranteed access time for the 6116LA20TPG?
The 6116LA20TPG has a maximum guaranteed 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 specified in the AC Electrical Characteristics table of the Renesas datasheet revision Jul.17.20. The 6116LA20TPG achieves this performance using advanced CMOS process technology optimized for speed and low power.
Does the 6116LA20TPG support battery backup operation, and what voltage is required?
Yes, the 6116LA20TPG supports battery backup operation with a minimum data retention voltage of 2.0 V - a feature exclusive to the LA version. At this voltage, typical retention current is ≤0.5 µA across all temperatures. This capability is confirmed in the Data Retention Characteristics table (Table 10) of the official Renesas datasheet for the 6116LA20TPG.
What package type and pin count does the 6116LA20TPG use?
The 6116LA20TPG uses a 24-pin 300-mil plastic dual in-line package (PDIP), identified by package code PTG24 per Renesas ordering information. It features through-hole mounting, standard 0.1-inch pin pitch, and is mechanically and electrically compatible with legacy 2114/6116 socket footprints. This is explicitly listed in the Orderable Part Information table on page 11 of the datasheet.
Is the 6116LA20TPG TTL-compatible, and how does that affect system integration?
Yes, the 6116LA20TPG has TTL-compatible inputs and outputs - VIH = 2.2 V min, VIL = 0.8 V max, VOL = 0.4 V max, VOH = 2.4 V min - enabling direct connection to 5 V microprocessors like Z80, 8085, and 68000 without level shifters. This compatibility is documented in the DC Electrical Characteristics tables (Tables 6–7) and confirms seamless integration into legacy bus architectures.
What is the standby current consumption of the 6116LA20TPG in full CMOS-level standby mode?
In full CMOS-level standby mode (CS > VHC, VIN < VLC or VIN > VHC), the 6116LA20TPG draws ≤0.1 mA of supply current (ISB1) at VCC = 5.5 V and TA = +25°C. This ultra-low value is specified in Table 8 of the Renesas datasheet and enables multi-year data retention on small lithium coin cells - a defining characteristic of the LA variant.
