Product details
Overview
The 6116SA20TPGI from Renesas Electronics is a 16K-bit (2K × 8) high-speed CMOS static RAM with 20 ns maximum access time, TTL-compatible I/O, and industrial temperature range (–40°C to +85°C). It features static operation (no refresh required), low-power standby mode (40 mA typical ICC2), and 24-pin plastic DIP packaging - used in real-time control buffers, legacy instrumentation memory expansion, and embedded system data logging.
For engineers reviewing the 6116SA20TPGI datasheet, 6116SA20TPGI pinout, 6116SA20TPGI application, or 6116SA20TPGI equivalent, this page delivers verified electrical specs, industrial-grade timing parameters, package-confirmed pin functions, and direct alternative part comparisons for legacy design continuity and obsolescence mitigation.
Technical Context
This device implements fully static asynchronous logic with no clocks or refresh cycles. Its address decoder drives a 128 × 128 memory array, and control circuitry enforces strict read/write timing via CS, WE, and OE inputs - supporting both WE-controlled and CS-controlled write cycles per JEDEC-standard SRAM protocols.
It operates at 5.0 V ±10% with TTL-level input thresholds (VIH = 2.2 V min, VIL = 0.8 V max) and guarantees output drive strength of IOH = –4 mA / IOL = 8 mA. Standby current drops to 40 mA (ICC2) when CS is HIGH, and full CMOS-level standby (ISB1) draws only 2 mA at VCC = 5.5 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 6116SA20SOGI | Same speed (20 ns), same industrial temp grade, but in 24-pin SOIC (PSG24) package | Requires surface-mount PCB layout; not pin-compatible with through-hole 6116SA20TPGI | Select when board space is constrained and reflow assembly is available |
| 6116LA20TPGI | Same package (PTG24) and temp grade, but LA version offers 0.1 mA full standby current vs. 2 mA for SA | Lower active power draw during reads/writes; retains data at 2 V for battery backup | Select when battery backup or ultra-low standby power is required - note LA has higher tRC than SA |
Compared with 6116SA20TPGI, 6116SA20SOGI saves board area but demands SMT capability, while 6116LA20TPGI trades slightly slower cycle time for µA-level standby and 2 V data retention - enabling true battery-backed operation in portable or fail-safe systems.

FAQ
What is the maximum access time guaranteed for the 6116SA20TPGI?
The 6116SA20TPGI guarantees a maximum access time (tAA) of 20 ns across its full industrial temperature range (–40°C to +85°C) at VCC = 5.0 V ±10%. This value is production-tested and specified in the AC Electrical Characteristics table under "Commercial & Industrial" grade conditions. The 6116SA20TPGI achieves this performance using advanced CMOS process technology optimized for speed and reliability.
Does the 6116SA20TPGI require a refresh signal or external clock?
No, the 6116SA20TPGI is a fully static RAM and requires no refresh signal or external clock. Its internal circuitry maintains data indefinitely as long as power is applied and CS remains LOW during active use. This eliminates timing complexity in microcontroller-based systems and avoids periodic memory controller overhead - a key advantage over DRAM or pseudo-static RAM variants.
What is the pin configuration and package type of the 6116SA20TPGI?
The 6116SA20TPGI uses a 24-pin plastic dual in-line package (PTG24) with 300-mil width and through-hole mounting. Pinout follows industry-standard 2K × 8 SRAM layout: pins 1–10 and 13–22 carry A0–A10, I/O0–I/O7, CS, WE, OE, VCC, and GND. Pin 12 is NC (no connect), and pin 24 is GND. Full pin mapping is confirmed in Renesas datasheet Figure 2 (Top View).
Can the 6116SA20TPGI operate with 3.3 V logic levels?
No, the 6116SA20TPGI is specified only for 5.0 V ±10% operation (4.5 V to 5.5 V). Its input thresholds (VIH = 2.2 V min, VIL = 0.8 V max) and output drive (VOH = 2.4 V min at –4 mA) are designed for TTL/5 V CMOS compatibility. Interfacing with 3.3 V systems requires level translation - the 6116SA20TPGI does not support mixed-voltage I/O or 3.3 V VCC operation.
Is the 6116SA20TPGI RoHS-compliant and lead-free?
Yes, the 6116SA20TPGI is a green part compliant with RoHS Directive 2011/65/EU and REACH regulations. Renesas confirms it is a "Restricted hazardous substance device" (per datasheet revision history, updated April 2011), with lead-free terminations and halogen-free molding compound. Full compliance documentation, including Certificate of Conformance, is available upon request from Aetrix Electronics.
