Substitute Part Grouping Explanation

The MC56F84786VLK qualifies as a parametric equivalent to the PC56F84786VLK based on identical electrical and mechanical specifications across all critical substitution parameters:

• Identical core processor (56800EX) and architecture (32-bit single-core)
• Matching clock speed (100MHz)
• Identical memory configuration (256KB FLASH, 2K x 8 EEPROM, 32K x 8 RAM)
• Identical I/O count (68 pins)
• Identical package specification (80-LQFP, 12x12mm)
• Identical voltage supply range (3V ~ 3.6V)
• Identical operating temperature range (-40°C ~ 105°C)
• Matching connectivity interfaces (CANbus, I2C, LINbus, SCI, SPI)
• Identical peripheral feature set (Brown-out Detect/Reset, DMA, LVD, POR, PWM, WDT)
• Identical data converter specifications (A/D 16x12b, 10x16b; D/A 1x12b)

The primary distinction is product status: PC56F84786VLK is Obsolete, while MC56F84786VLK is Active.

Parameter Comparison

Engineering Selection Recommendations

The MC56F84786VLK is the direct parametric equivalent for PC56F84786VLK replacement. Selection of MC56F84786VLK is supported by:

• Full electrical and mechanical parameter alignment with the obsolete part
• Active product status ensuring ongoing availability and manufacturing support
• Identical RoHS3 compliance and REACH status
• Matching regulatory classifications (ECCN, HTSUS)
• Equivalent moisture sensitivity level and handling requirements

For designs currently using PC56F84786VLK, transition to MC56F84786VLK requires no circuit modifications, firmware changes, or PCB layout alterations. The packaging difference (Tray vs. standard packaging) affects only procurement and handling procedures, not functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can MC56F84786VLK directly replace PC56F84786VLK in existing designs?

A: Yes. All electrical specifications, pin configurations, memory organization, and peripheral features are identical. No circuit redesign is required.

Q: What is the difference between PC56F84786VLK and MC56F84786VLK?

A: The primary difference is product status. PC56F84786VLK is Obsolete, while MC56F84786VLK is Active. MC56F84786VLK is supplied in Tray packaging. All functional and electrical parameters are identical.

Q: Are there any compatibility concerns with the 80-LQFP package?

A: No. Both parts use the identical 80-LQFP (12x12mm) package specification. PCB footprints, soldering procedures, and thermal management requirements are unchanged.

Q: Do the RoHS and REACH compliance statuses differ?

A: No. Both parts maintain ROHS3 compliance and REACH Unaffected status with identical moisture sensitivity levels (MSL 3, 168 hours).

Q: Is firmware compatibility guaranteed?

A: Yes. Identical core processor architecture (56800EX), clock speed (100MHz), and memory configuration ensure complete firmware compatibility without recompilation or modification.

Q: What supply voltage range applies to both parts?

A: Both parts operate within the identical 3V to 3.6V supply range. Power supply design and decoupling requirements remain unchanged.
