Product details
Overview
IDT71016S12YGI8 from Integrated Device Technology is a 64K × 16-bit (1 Mbit) high-speed CMOS static RAM with 12 ns access time, TTL-compatible I/O, single 5 V supply operation, and industrial temperature range (–40°C to +85°C). It features separate upper/lower byte enables, output enable with 7 ns latency, and low-power standby modes - deployed in real-time industrial controllers requiring deterministic memory access.
For engineers reviewing the IDT71016S12YGI8 datasheet, IDT71016S12YGI8 pinout, IDT71016S12YGI8 application, or IDT71016S12YGI8 equivalent, key selection criteria include byte-selectable 16-bit data width, SOJ-44 package compatibility, 12 ns read cycle timing, and industrial-grade reliability without refresh circuitry.
Technical Context
The IDT71016S12YGI8 implements fully static asynchronous architecture with no clocks or refresh required. Its dual-byte enable (BHE/BLE), independent chip select (CS), output enable (OE), and write enable (WE) support flexible bus interfacing in 16-bit microprocessor systems.
All inputs meet TTL voltage thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V), outputs drive ±4 mA/±8 mA loads, and bidirectional I/O buffers ensure clean signal integrity during read/write transitions with guaranteed tOHZ ≤ 6 ns and tCLZ ≤ 4 ns at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576 bits); supports full-word or byte-aligned access without external logic |

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, 3.3 V supply only | Requires level-shifting for 5 V systems; larger density but slower speed | Select only if migrating to 3.3 V architecture and higher capacity is prioritized over latency |
| AS6C1008-12ZIN | 128K × 8-bit, 12 ns access, 5 V supply, SOJ-32 | Narrower 8-bit bus; different pin count and byte-enable scheme | Choose when redesigning for 8-bit microcontrollers or constrained board area favors smaller SOJ-32 footprint |
Compared with CY62167EV30LL-45ZSXIT and AS6C1008-12ZIN, the IDT71016S12YGI8 uniquely delivers 12 ns 16-bit access at 5 V in SOJ-44 - preserving legacy 5 V bus timing and pinout compatibility where byte-selectable width is essential.

FAQ
What is the operating voltage range for IDT71016S12YGI8?
IDT71016S12YGI8 operates from 4.5 V to 5.5 V DC. This 5 V nominal supply range ensures full compatibility with legacy TTL and CMOS logic families, and all DC and AC specifications - including 12 ns access time and 10 µA standby current - are guaranteed across this voltage window at industrial temperatures.
Does IDT71016S12YGI8 require a clock or refresh signal?
No, IDT71016S12YGI8 uses fully static asynchronous circuitry and requires neither a clock nor periodic refresh. Data retention is indefinite as long as power is applied and the device remains within its specified voltage and temperature limits - simplifying system design for microcontroller-based applications where timing resources are constrained.
What package type is used for IDT71016S12YGI8?
IDT71016S12YGI8 is packaged in a 44-pin Plastic SOJ (SO44-1), 400-mil width, lead-free (G suffix), with industrial temperature qualification. Its pinout matches JEDEC standard SOJ-44 layouts, enabling drop-in replacement in existing designs using compatible 44-pin SOJ footprints.
How does byte enable functionality work on IDT71016S12YGI8?
IDT71016S12YGI8 provides independent BHE (high byte enable) and BLE (low byte enable) inputs to selectively activate I/O8–I/O15 or I/O0–I/O7 during read/write cycles. When only one byte enable is active, the opposite byte remains in high-impedance state - allowing 8-bit access on a 16-bit bus without external demultiplexing logic.
Is IDT71016S12YGI8 suitable for automotive applications?
IDT71016S12YGI8 is rated for industrial temperature (–40°C to +85°C) and meets relevant reliability standards, but it is not AEC-Q100 qualified. For automotive applications requiring formal qualification, designers should consult Renesas' post-acquisition documentation or consider purpose-qualified alternatives - though IDT71016S12YGI8 has been deployed in non-safety-critical automotive subsystems such as infotainment memory buffers.
