Substitute Part Grouping Explanation

Substitution for the AT91SAM9263B-CU is determined by strict equivalence across the following critical parameters:

• Core processor architecture: ARM926EJ-S
• Processing speed: 200MHz
• Bus width: 32-Bit, single core configuration
• Memory controller support: SDRAM and SRAM
• Peripheral integration: LCD controller, 10/100Mbps Ethernet, dual USB 2.0, CAN, I2C, SPI, UART/USART
• Package specification: 324-TFBGA (15x15)
• Voltage I/O compatibility: 1.8V through 3.3V
• Operating temperature range: -40°C to 85°C
• Compliance certifications: ROHS3, REACH Unaffected

The AT91SAM9263B-CU-100 is identified as a direct substitute based on identical electrical specifications, peripheral feature set, package form factor, and compliance status. The primary distinction is packaging format (Tray versus unspecified for the main part).

Parameter Comparison

Engineering Selection Recommendations

Both the AT91SAM9263B-CU and AT91SAM9263B-CU-100 are classified as obsolete products. Selection between these parts should be based on:

• Packaging format requirements: AT91SAM9263B-CU-100 is supplied in Tray packaging, which may be preferred for automated assembly or bulk procurement workflows.
• Inventory availability: Current stock levels differ between variants; procurement decisions should account for lead times and supply chain considerations.
• Compliance requirements: Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory standards.
• Thermal and electrical specifications: Both variants support identical operating temperature ranges (-40°C to 85°C) and voltage I/O levels (1.8V to 3.3V), ensuring functional interchangeability in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Are AT91SAM9263B-CU and AT91SAM9263B-CU-100 electrically interchangeable?

A: Yes. Both parts feature identical core processor architecture (ARM926EJ-S), clock speed (200MHz), memory controllers (SDRAM/SRAM), peripheral interfaces, voltage specifications, and operating temperature range. They are electrically equivalent and functionally interchangeable in circuit applications.

Q: What is the difference between AT91SAM9263B-CU and AT91SAM9263B-CU-100?

A: The primary difference is packaging format. AT91SAM9263B-CU-100 is supplied in Tray packaging, while the base part number does not specify a packaging format. All electrical and functional specifications are identical.

Q: Can I use AT91SAM9263B-CU-100 as a direct replacement in PCB assembly?

A: Yes. The 324-TFBGA (15x15) package footprint is identical for both parts. PCB layout, solder reflow profiles, and assembly procedures remain unchanged. Verify packaging format compatibility with your assembly process requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance status and REACH Unaffected designation. Moisture Sensitivity Level (MSL) is 3 (168 Hours) for both variants, requiring identical handling and storage protocols.

Q: Why is the AT91SAM9263B-CU marked as obsolete?

A: Product status reflects Microchip Technology's lifecycle classification. Obsolete designation indicates the part is no longer in active production. Existing inventory remains available for procurement; however, long-term availability cannot be guaranteed. Design teams should evaluate migration to current-generation microprocessor alternatives for new product development.
