Product details
Overview
71024S20TYGI from Renesas Electronics is a 128K × 8-bit (1 Mbit) high-speed CMOS static RAM with industrial temperature support (–40°C to +85°C), 20 ns read/write cycle time, TTL-compatible I/O, and dual chip select plus output enable control. It operates from a single 5.0 V ±0.5 V supply and is used in real-time data buffering for industrial controllers and legacy embedded systems requiring asynchronous, no-refresh memory.
For engineers reviewing the 71024S20TYGI datasheet, 71024S20TYGI pinout, 71024S20TYGI application, or 71024S20TYGI equivalent, key selection criteria include access time consistency (tAA = tRC = 20 ns), low standby current (ISB1 = 10 mA), SOJ-32 package compatibility, and industrial-grade reliability without refresh circuitry.
Technical Context
The 71024S20TYGI implements fully static asynchronous architecture-no clocks, no refresh cycles-enabling deterministic timing across its full address space (A0–A16). Its bidirectional I/O pins interface directly with TTL logic, and dual chip selects (CS1, CS2) allow hierarchical memory mapping in multi-bank systems.
Output enable (OE) provides sub-8 ns output valid delay (tOE ≤ 8 ns), while write enable (WE) controls data latching during overlapping CS1/CS2 activation. Power management includes two standby modes: ISB (TTL-level deselect, 40 mA) and ISB1 (CMOS-level full standby, 10 mA).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62128EV30LL-70ZSXI | 512K × 8-bit (4 Mbit), 70 ns access, 3.3 V supply only; SOJ-32 pinout differs (VCC/GND placement) | Higher density but slower speed and incompatible voltage; unsuitable for 5 V legacy backplanes | Select only if migrating to 3.3 V systems and requiring >1 Mbit capacity |
| AS6C1008-20TIN | 128K × 8-bit, 20 ns, 5 V, SOJ-32-but uses single CS (no CS2), lacks ISB1 mode (min ISB = 25 mA) | Reduced power management flexibility; no hierarchical chip select for banked addressing | Acceptable for simple single-bank designs where ISB1 savings are not required |
Compared with CY62128EV30LL-70ZSXI and AS6C1008-20TIN, the 71024S20TYGI uniquely delivers 20 ns performance at 5 V with dual CS architecture and 10 mA ISB1-making it the only drop-in solution for industrial 5 V systems requiring both speed and low-power standby.

FAQ
What is the operating voltage range for the 71024S20TYGI?
The 71024S20TYGI operates from a single 5.0 V supply with a specified range of 4.5 V to 5.5 V. This 5 V tolerance ensures compatibility with legacy TTL-based systems and eliminates the need for additional voltage regulation in existing industrial designs using the 71024S20TYGI.
Does the 71024S20TYGI require a clock or refresh signal?
No, the 71024S20TYGI uses fully static CMOS circuitry and requires neither a clock nor periodic refresh cycles. This architecture simplifies system timing design and guarantees data retention as long as power and temperature remain within specification-critical for the 71024S20TYGI's use in safety-critical industrial controllers.
What is the meaning of "TY" in the 71024S20TYGI part number?
In the 71024S20TYGI ordering code, "TY" denotes the 300-mil Plastic SOJ package (PJG32) with tube packaging. The "I" suffix confirms industrial temperature grade (–40°C to +85°C), and "G" indicates RoHS-compliant green material. This full designation uniquely identifies the 71024S20TYGI variant.
How does the dual chip select (CS1/CS2) function on the 71024S20TYGI?
The 71024S20TYGI uses CS1 (active-low) and CS2 (active-high) together to enable the device: CS1 must be LOW and CS2 HIGH for normal operation. This dual-signal scheme prevents spurious activation and supports hierarchical memory decoding-essential for reliable operation in complex backplane systems using the 71024S20TYGI.
Is the 71024S20TYGI pin-compatible with other IDT71024 speed grades?
Yes, all IDT71024 variants-including 71024S12TYGI, 71024S15TYGI, and 71024S20TYGI-share identical 32-pin PJG32 SOJ pinouts and electrical interfaces. This allows direct speed-grade substitution in the same PCB layout, provided timing margins accommodate the selected 71024S20TYGI access time.
