Product details
Overview
71024S20TYGI8 from Renesas Electronics is a 128K × 8-bit (1 Mbit) high-speed CMOS static RAM with industrial temperature range (–40°C to +85°C), 20 ns access time, TTL-compatible I/O, and dual chip select plus output enable control. It operates from a single 5.0 V ±10% supply and requires no refresh or clocking.
For engineers reviewing the 71024S20TYGI8 datasheet, 71024S20TYGI8 pinout, 71024S20TYGI8 application, or 71024S20TYGI8 equivalent, key selection criteria include industrial-grade timing consistency, SOJ-32 package compatibility, low standby current (ISB1 = 10 mA), and bidirectional TTL-level data bus interfacing in legacy memory subsystems.
Technical Context
The 71024S20TYGI8 implements fully static asynchronous logic with no internal clocks or refresh cycles. Its address access time (tAA ≤ 20 ns) and read cycle time (tRC = 20 ns) are guaranteed across the full industrial temperature range under VCC = 5.0 V ±10%.
It features two independent chip selects (CS1, CS2) and a dedicated output enable (OE), enabling flexible memory banking and bus sharing. All I/O pins support bidirectional TTL-compatible signaling with VOH ≥ 2.4 V (IOH = –4 mA) and VOL ≤ 0.4 V (IOL = 8 mA).

FAQ
What is the operating temperature range specified for the 71024S20TYGI8?
The 71024S20TYGI8 is rated for industrial operation from –40°C to +85°C. This range is guaranteed across all AC and DC electrical specifications in the datasheet, including access time (tAA ≤ 20 ns), standby current (ISB1 = 10 mA), and I/O voltage thresholds. The "I" suffix in the part number explicitly denotes industrial temperature grade.
Does the 71024S20TYGI8 require a refresh circuit or clock signal?
No, the 71024S20TYGI8 is a fully static RAM and requires neither refresh cycles nor clock inputs. Its asynchronous design uses only address, data, and control signals (CS1, CS2, OE, WE) for operation. This eliminates timing complexity associated with DRAM controllers and makes it ideal for simple microcontroller or FPGA-based memory interfaces.
What package type and pin count does the 71024S20TYGI8 use?
The 71024S20TYGI8 uses a 32-pin Plastic Small Outline J-Lead (SOJ) package, 300 mil wide, designated PJG32. This JEDEC-standard surface-mount package has gull-wing leads and is compatible with reflow soldering processes. Pin 1 is identified by a notch or dot on the package body per datasheet drawing 2964 drw 02.
How does the dual chip select (CS1/CS2) architecture of the 71024S20TYGI8 improve system design?
The 71024S20TYGI8's CS1 (active-low) and CS2 (active-high) inputs enable hierarchical memory decoding without external logic gates. For example, CS2 can be tied to a higher-order address bit while CS1 connects to a bank-select signal - allowing clean separation of memory regions. This reduces gate count and routing complexity in multi-SRAM systems compared to single-CS alternatives.
What is the maximum output drive capability of the 71024S20TYGI8 I/O pins?
The 71024S20TYGI8 I/O pins deliver VOH ≥ 2.4 V at IOH = –4 mA and sink VOL ≤ 0.4 V at IOL = 8 mA under VCC = 4.5 V minimum, confirming full TTL compatibility. These values are guaranteed across the industrial temperature range and allow direct interfacing with standard 5 V microcontrollers, FPGAs, and peripheral ICs without external buffers or level translators.
