Product details
Overview
71024S12TYGI from Renesas Electronics is a 128K × 8-bit (1 Mbit) high-speed CMOS static RAM with 12 ns access time, industrial temperature range (–40°C to +85°C), single 5V supply operation, TTL-compatible I/O, and dual chip select plus output enable control. It serves as fast, fully static main or cache memory in embedded controllers, industrial PLCs, and legacy communication interface buffers.
For engineers reviewing the 71024S12TYGI datasheet, 71024S12TYGI pinout, 71024S12TYGI application, or 71024S12TYGI equivalent, key selection criteria include guaranteed 12 ns read cycle time, industrial-grade reliability, SOJ-32 300-mil package compatibility, and low-power standby modes (ISB1 = 10 mA).
Technical Context
The 71024S12TYGI implements fully asynchronous static RAM architecture with no clocks or refresh required. Its bidirectional I/O pins support direct TTL-level interfacing, and dual chip selects (CS1, CS2) enable hierarchical memory mapping in multi-bank systems.
Operation relies on three independent control signals-WE (write enable), OE (output enable), and CS1/CS2-with defined priority logic: CS1 low + CS2 high enables device selection; OE low enables read outputs; WE low initiates write cycles. Standby current drops to 10 mA when CS1 ≥ VHC or CS2 ≤ VLC.
Key Specifications

Pinout & Package
71024S12TYGI is housed in a 32-pin Plastic SOJ (Shrink Outline J-Lead) package, 300 mil wide (PJG32), with gull-wing leads suitable for wave or reflow soldering. Pin 1 is marked by a notch or dot; top view orientation matches standard JEDEC SOJ conventions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K-word decoding; A16 is MSB |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel data path; direction controlled by WE and OE states |
| CS1, CS2 | Chip Select Inputs | Active-low (CS1) and active-high (CS2) enable hierarchical memory banking |
| OE | Output Enable | Active-low control of output drivers; tOE = 6 ns max ensures fast read response |

FAQ
What is the maximum guaranteed access time for the 71024S12TYGI?
The 71024S12TYGI has a maximum guaranteed address access time (tAA) of 12 ns under industrial conditions (–40°C to +85°C, VCC = 4.5 V to 5.5 V). This value is production-tested and applies to all operating corners, enabling reliable timing closure in real-time control applications without margining.
Does the 71024S12TYGI require a clock or refresh signal?
No, the 71024S12TYGI uses fully static CMOS circuitry and requires neither a clock nor periodic refresh. It retains data indefinitely as long as power is applied and control signals meet specification - simplifying system design and eliminating refresh overhead in microcontroller-based systems.
What package type and dimensions does the 71024S12TYGI use?
The 71024S12TYGI is packaged in a 32-pin Plastic SOJ (Shrink Outline J-Lead) with 300-mil body width (package code PJG32). Lead pitch is 0.05 inches (1.27 mm), and overall package width is 7.62 mm - matching JEDEC MS-012AC standards for drop-in replacement in existing SOJ footprints.
How does chip select logic work on the 71024S12TYGI?
The 71024S12TYGI uses two independent chip selects: CS1 (active-low) and CS2 (active-high). The device is selected only when CS1 is low AND CS2 is high. If either condition fails, the device enters standby mode (ISB or ISB1), disabling outputs and reducing current draw to 40 mA or 10 mA respectively.
Is the 71024S12TYGI RoHS-compliant and lead-free?
Yes, the 71024S12TYGI is a green, RoHS-compliant device with lead-free terminations. The "G" suffix in the part number confirms compliance with EU Directive 2011/65/EU and Renesas' hazardous substance restrictions, including elimination of Pb, Cd, Hg, Cr⁶⁺, PBB, and PBDE.
