Substitute Part Grouping Explanation

Substitution of the XC2364B40F80LABKXUMA1 is determined by strict equivalence across the following critical parameters:

Core Processor Architecture: C166SV2 (identical processor core required)
Memory Configuration: 320KB FLASH and 34KB RAM (exact capacity match)
Operating Frequency: 80MHz (clock speed equivalence)
Voltage Supply Range: 3V ~ 5.5V (power supply compatibility)
I/O Count: 76 pins (functional pin count)
Connectivity Interfaces: CANbus, EBI/EMI, I2C, LINbus, SPI, SSC, UART/USART, USI (peripheral feature set)
Package Type: 100-LQFP Exposed Pad (physical form factor)
Mounting Technology: Surface Mount (assembly compatibility)

The XC2365B40F80LRABKXUMA1 meets all substitution criteria as a direct equivalent within the XC23xxB microcontroller family.

Compliance Enhancement: The substitute part is ROHS3 compliant, meeting current environmental and regulatory requirements.
Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, suitable for automated assembly processes, whereas the original part is supplied in bulk packaging.
Inventory Availability: The substitute part has higher current inventory (3025 Pcs) compared to the original (828 Pcs).

Frequently Asked Questions (FAQ)

Q: Are the XC2364B40F80LABKXUMA1 and XC2365B40F80LRABKXUMA1 pin-compatible?

A: Yes. Both devices use the 100-LQFP Exposed Pad package with identical pin assignments, I/O count (76 pins), and electrical characteristics. Direct PCB-level substitution is supported without layout modifications.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging format. The XC2364B40F80LABKXUMA1 is obsolete and supplied in bulk; the XC2365B40F80LRABKXUMA1 is Last Time Buy status and supplied in Tape & Reel format. All functional specifications are identical.

Q: Can I use the XC2365B40F80LRABKXUMA1 in existing designs using the XC2364B40F80LABKXUMA1?

A: Yes. The substitute part is functionally equivalent across all electrical, memory, and peripheral parameters. No firmware, software, or circuit modifications are required for direct substitution.

Q: What does Last Time Buy status mean for the XC2365B40F80LRABKXUMA1?

A: Last Time Buy indicates that Infineon will continue to supply this part for a limited period before discontinuation. This provides a defined window for procurement and design transition planning.

Q: Is the XC2365B40F80LRABKXUMA1 ROHS compliant?

A: Yes. The XC2365B40F80LRABKXUMA1 is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The original XC2364B40F80LABKXUMA1 compliance status is not specified in available documentation.
