The P82C605F is a microcontroller peripheral chip manufactured by CHIPS. Below are the factual specifications, descriptions, and features:

Manufacturer:

• CHIPS (formerly Chips and Technologies)

Part Number:

• P82C605F

Description:

• The P82C605F is a Dual Programmable Interrupt Controller (PIC) designed for use in microprocessor-based systems.
• It provides interrupt management capabilities for systems requiring multiple interrupt sources.
• Compatible with Intel’s 8259A PIC architecture but with enhanced features.

Key Features:

1. Dual Interrupt Controller Configuration:

• Combines two independent 8259A-compatible interrupt controllers in a single chip.
• Supports Master-Slave operation for expanded interrupt handling.

2. Interrupt Handling:

• Manages up to 16 interrupt levels (when configured in cascaded mode).
• Supports edge-triggered and level-triggered interrupt inputs.

3. Programmable Priority Modes:

• Fully nested mode (default priority order).
• Rotating priority mode (equal priority handling).
• Special mask mode (selective masking of interrupts).

4. Cascading Support:

• Can be cascaded with additional P82C605F or 8259A-compatible controllers.

5. Compatibility:

• Fully compatible with Intel 8259A architecture.
• Works with x86-based systems and other microprocessors.

6. Package:

• Available in a PLCC (Plastic Leaded Chip Carrier) package.

7. Operating Voltage:

• Typically operates at 5V.

8. Applications:

• Used in PC/AT-compatible systems, embedded controllers, and industrial automation.

Notes:

• The P82C605F is an older IC and may be considered obsolete in modern designs.
• Replacement or equivalent parts may be required for current applications.
