Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R5F21262SYFP#V2 is determined by strict alignment of the following critical parameters:

• Core processor architecture (R8C)
• Core size (16-Bit)
• Operating frequency (20MHz)
• Program memory capacity (8KB FLASH)
• RAM capacity (512 x 8)
• Supply voltage range (2.2V ~ 5.5V)
• Data converter specifications (A/D 12x10b)
• I/O count (25 pins)
• Connectivity interfaces (I2C, LINbus, SIO, SSU, UART/USART)
• Package type (32-LQFP 7x7)
• Operating temperature range (-20°C ~ 85°C)

The R5F21272SNFP#V2 qualifies as a substitute part based on matching all core electrical and mechanical parameters. The primary distinction is the addition of 2K x 8 EEPROM in the substitute part, which represents an enhancement rather than a functional deviation.

Parameter Comparison

Engineering Selection Recommendations

The R5F21272SNFP#V2 is suitable as a substitute for the R5F21262SYFP#V2 based on the following factors:

• Both parts maintain identical core electrical specifications, including processor architecture, clock frequency, memory capacity, and I/O configuration
• The R5F21272SNFP#V2 carries Active product status, ensuring continued availability and manufacturing support, whereas the main part is classified as Obsolete
• Both parts comply with ROHS3 and maintain equivalent moisture sensitivity ratings
• The addition of 2K x 8 EEPROM in the substitute part provides enhanced functionality without altering the core microcontroller operation
• Identical packaging (32-LQFP 7x7) ensures mechanical compatibility with existing PCB layouts
• Both parts operate within the same voltage supply range and temperature specifications

Frequently Asked Questions (FAQ)

Q: Can the R5F21272SNFP#V2 directly replace the R5F21262SYFP#V2 in existing designs?

A: Yes. Both parts share identical core processor architecture, clock speed, program memory capacity, RAM, I/O count, connectivity interfaces, and package specifications. The primary difference is the addition of 2K x 8 EEPROM in the substitute part, which does not affect compatibility with designs that do not utilize this feature.

Q: What is the significance of the EEPROM addition in the R5F21272SNFP#V2?

A: The R5F21272SNFP#V2 includes 2K x 8 bytes of EEPROM, whereas the R5F21262SYFP#V2 does not. This provides additional non-volatile storage capacity for applications requiring persistent data retention. Designs not utilizing EEPROM functionality are unaffected by this difference.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 32-LQFP (7x7mm) package, ensuring identical PCB footprint and pin layout compatibility.

Q: Why is the main part classified as Obsolete?

A: The R5F21262SYFP#V2 is listed as Obsolete, indicating that Renesas Electronics Corporation has discontinued active manufacturing and support. The R5F21272SNFP#V2 maintains Active status, making it the recommended choice for new designs and ongoing system support.

Q: Do both parts comply with the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, with identical moisture sensitivity levels (MSL 3, 168 hours).
