Key Features

• Core Density  224 logic elements (≈4,500 gates) for implementing small- to mid-scale programmable logic functions.
• On‑Chip Memory  46,064 bits of embedded RAM (approximately 0.046 Mbits) to support local data buffering, state storage, and small lookup tables.
• I/O Count  Up to 70 general-purpose I/O pins, enabling multiple peripheral interfaces and system glue logic integration.
• Power Supply  Operates from a 4.5 V to 5.5 V supply range suitable for standard TTL/legacy 5 V systems.
• Package & Mounting  84-LCC (J-Lead) / 84-PLCC package (29.31 × 29.31 mm) with surface-mount mounting for compact PCB implementations.
• Industrial Temperature Grade  Rated for −40 °C to 85 °C operation for use in industrial temperature environments.
• Regulatory  RoHS compliant for use in lead-free manufacturing processes.

Typical Applications

• Industrial Control Logic  Implement control state machines, interface bridging, and custom timing logic using 224 logic elements and local RAM.
• Embedded System Glue  Provide programmable glue between processors and peripherals with up to 70 I/O pins and on-chip memory for buffering.
• Prototyping and Development  Evaluate and prototype small digital functions or proof-of-concept designs within a compact PLCC package.
• Legacy 5V Systems  Integrate into existing 4.5 V–5.5 V voltage domains where surface-mount packaging and industrial temperature range are required.

Unique Advantages

• Right‑sized Logic Density: 224 logic elements and ≈4,500 gates provide a balance between capability and board-level cost for small- to mid-scale designs.
• Integrated Memory: 46,064 bits of on-chip RAM reduces external memory requirements for buffering and small LUTs, simplifying PCB design.
• Flexible I/O Count: 70 I/O pins enable interfacing to many peripherals without immediate need for external port expanders.
• Industrial Temperature Support: −40 °C to 85 °C rating ensures reliable operation across standard industrial environments.
• Surface‑Mount PLCC Packaging: 84-LCC (J-lead) with a 29.31 × 29.31 mm footprint supports compact layouts and automated assembly.
• RoHS Compliance: Conforms to lead-free manufacturing processes for regulated product lines.
