Product details
Overview
71016S15YGI8 from Renesas Electronics is a 64K × 16-bit (1 Mbit) high-speed CMOS static RAM with 15 ns access time, TTL-compatible I/O, single 5V supply operation, and separate upper/lower byte enable for embedded memory subsystems in industrial controllers and legacy computing systems.
For engineers reviewing the 71016S15YGI8 datasheet, 71016S15YGI8 pinout, 71016S15YGI8 application, or 71016S15YGI8 equivalent, this device supports asynchronous word/byte read/write operations with fast chip select and output enable timing, low standby current (50 mA max at industrial temp), and JEDEC-standard 44-pin SOJ packaging for drop-in replacement in legacy SRAM-based designs.
Technical Context
The 71016S15YGI8 implements fully static asynchronous logic with no clocks or refresh required. Its architecture includes independent BHE/BLE controls enabling byte-level writes without disturbing adjacent data, and bidirectional TTL-compatible I/O buffers supporting direct interfacing to 5V microprocessor buses.
It operates across –40°C to +85°C (industrial grade), uses CMOS process technology for low power, and features three distinct standby modes-TTL-level (ISB = 50 mA), CMOS-level (ISB1 = 10 mA), and deselected high-impedance-with VCC = 5.0 V ±10%.

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXIT | 512K × 16-bit, 45 ns access, 3.3V core (with 5V-tolerant I/O), TSOP-44 | Higher density but slower speed; requires 3.3V supply with level-tolerant I/O | Select when upgrading capacity is prioritized over speed and existing 5V-only infrastructure must be preserved |
| AS6C1008-15TIN | 128K × 8-bit, 15 ns access, 5V-only, SOJ-32 | 8-bit bus width, smaller density, different pin count and byte-enable scheme | Choose only if board redesign accommodates 32-pin footprint and 8-bit data path reconfiguration |
Compared with CY62167EV30LL-45ZSXIT and AS6C1008-15TIN, the 71016S15YGI8 uniquely delivers 16-bit-wide 64K organization, true 5V-only operation, and SOJ-44 pinout-making it the sole drop-in replacement for legacy designs requiring exact electrical, timing, and mechanical compatibility.

FAQ
What is the operating temperature range for the 71016S15YGI8?
The 71016S15YGI8 is rated for industrial temperature operation from –40°C to +85°C. This specification is validated per Renesas' industrial qualification standards and applies to all AC and DC parameters in the datasheet, including access time (tAA ≤ 15 ns), standby current (ISB ≤ 50 mA), and input/output voltage thresholds. The "I" suffix in the part number explicitly denotes this industrial grade.
Does the 71016S15YGI8 require a refresh circuit or clock signal?
No, the 71016S15YGI8 uses fully static CMOS memory cells and requires no refresh cycles or clock input. It operates asynchronously using only CS, OE, WE, BHE, and BLE control signals. This eliminates timing-critical refresh overhead and simplifies integration into microcontroller, FPGA, or discrete logic-based memory subsystems-exactly as implemented in the original IDT-designed 71016 family now rebranded by Renesas.
What package type and pin count does the 71016S15YGI8 use?
71016S15YGI8 uses a 44-pin Plastic SOJ (PBG44) package with gull-wing leads, conforming to JEDEC MO-050AC. The "Y" in the part number indicates SOJ, "G" denotes green (RoHS-compliant) finish, "I" specifies industrial temperature, and "8" signifies tape-and-reel packaging. Pinout matches industry-standard 44-pin SOJ SRAM footprints, enabling direct PCB replacement.
Can the 71016S15YGI8 interface directly with a 5V microprocessor bus?
Yes, the 71016S15YGI8 features fully TTL-compatible inputs and outputs, with VIH(min) = 2.2 V and VOL(max) = 0.4 V at IOL = 8 mA-all specified at VCC = 4.5 V to 5.5 V. This allows direct connection to 5V microprocessors such as the Intel 80C186, Motorola 68000 derivatives, and Zilog Z180 without level-shifting circuitry, preserving signal integrity and reducing BOM cost.
What is the difference between BHE and BLE on the 71016S15YGI8?
BHE (Bus High Enable) and BLE (Bus Low Enable) are independent active-low byte-select controls on the 71016S15YGI8. BHE gates I/O8–I/O15 (high byte), while BLE gates I/O0–I/O7 (low byte). When both are low, a full 16-bit word is written or read; when only one is low, only its corresponding byte is accessed-enabling precise partial-word updates essential in real-time control and protocol stack implementations without disturbing adjacent data.
