• MSL Rating: 3 (168 Hours) (identical moisture sensitivity level)
• Operating Temperature Range: -40°C ~ 105°C (TA) (identical thermal operating window)
• Mounting Type: Surface Mount (same mounting technology)

Functional Differences Permitted in Substitution:

• Core Architecture: 16-Bit (upgraded from 8-Bit)
• Processing Speed: 24MHz (upgraded from 10MHz)
• Program Memory: 8KB FLASH (upgraded from 4KB)
• RAM: 768 x 8 (upgraded from 384 x 8)
• EEPROM: 2K x 8 (added feature)
• Data Converters: A/D 6x8/12b (enhanced from 5x10b)
• I/O Count: 11 (increased from 9)
• Connectivity: CSI, I2C, UART/USART (added interfaces)
• Package: 20-LSSOP (different from 16-SSOP)
• Voltage Supply: 1.6V ~ 3.6V (narrower range than 2.7V ~ 5.5V)

Parameter Comparison

Engineering Selection Recommendations

Selection between UPD78F0750MA-FAA-AX and R5F11768GSP#30 is determined by application memory and processing requirements:

UPD78F0750MA-FAA-AX Selection Criteria:

• Applications requiring 4KB program memory capacity are sufficient
• 10MHz processing speed meets application timing requirements
• 9 I/O pins satisfy interface requirements
• 16-SSOP package footprint is compatible with PCB layout constraints
• Supply voltage range 2.7V ~ 5.5V accommodates power supply design
• PWM peripheral availability is required

R5F11768GSP#30 Selection Criteria:

• Applications requiring 8KB program memory capacity
• 24MHz processing speed is necessary for performance requirements
• 11 I/O pins are required for expanded interface connectivity
• 20-LSSOP package footprint is compatible with PCB layout constraints
• Supply voltage range 1.6V ~ 3.6V is compatible with power supply design
• EEPROM storage and enhanced data converter resolution are required
• CSI, I2C, UART/USART connectivity is necessary

Both parts maintain Active product status, ROHS3 compliance, identical MSL ratings, and identical operating temperature ranges. Package differences (16-SSOP versus 20-LSSOP) require PCB redesign consideration.

Frequently Asked Questions (FAQ)

Q: Can R5F11768GSP#30 directly replace UPD78F0750MA-FAA-AX without firmware modification?

A: Direct replacement requires firmware evaluation. The R5F11768GSP#30 operates at 24MHz versus 10MHz, uses 16-Bit architecture versus 8-Bit, and features different peripheral configurations. Timing-dependent code and peripheral initialization routines require validation. Package differences (16-SSOP to 20-LSSOP) necessitate PCB redesign.

Q: What are the voltage supply compatibility considerations?

A: UPD78F0750MA-FAA-AX operates at 2.7V ~ 5.5V. R5F11768GSP#30 operates at 1.6V ~ 3.6V. Applications using supply voltages above 3.6V cannot use R5F11768GSP#30. Applications using supply voltages below 2.7V cannot use UPD78F0750MA-FAA-AX.

Q: Are the package dimensions compatible for PCB layout?

A: Both packages maintain 0.173" (4.40mm) width. UPD78F0750MA-FAA-AX uses 16-SSOP configuration. R5F11768GSP#30 uses 20-LSSOP configuration. Pin count and footprint differ, requiring PCB layout modification.

Q: Do both parts meet the same environmental compliance standards?

A: Both parts are ROHS3 Compliant with MSL Rating 3 (168 Hours) and identical operating temperature range -40°C ~ 105°C (TA). R5F11768GSP#30 carries REACH Affected status while UPD78F0750MA-FAA-AX carries REACH Unaffected status.

Q: What peripheral differences affect application design?

A: UPD78F0750MA-FAA-AX includes PWM peripheral. R5F11768GSP#30 does not list PWM but includes CSI, I2C, and UART/USART connectivity. Application requirements for PWM functionality or serial communication interfaces determine part selection.

Q: Is the increased memory in R5F11768GSP#30 backward compatible?

A: Increased program memory (8KB versus 4KB), RAM (768 x 8 versus 384 x 8), and added EEPROM (2K x 8) provide expanded capacity. Firmware designed for 4KB memory operates within 8KB capacity. However, architectural differences (8-Bit versus 16-Bit) and peripheral variations require code validation.
