Key Parameters

Substitute Part Grouping Explanation

Substitution of the R5F2L387CDFP#30 is determined by strict equivalence across the following critical parameters:

Memory Configuration: Program memory must be 48KB FLASH, EEPROM must be 4K x 8, and RAM must be 6K x 8. These specifications define the functional capacity of the microcontroller and cannot be altered without redesign.

Processor Architecture: The R8C core processor and 16-bit core size establish the instruction set and computational capability. Substitutes must maintain identical processor architecture.

Operating Specifications: Clock speed of 20MHz, supply voltage range of 1.8V to 5.5V, and operating temperature range of -20°C to 85°C must be preserved to ensure functional compatibility within existing circuit designs.

Peripheral Integration: The presence of LCD driver, PWM, watchdog timer, voltage detection, and the specific connectivity options (I2C, LINbus, SIO, SSU, UART/USART) must be maintained.

Package Specification: The 80-LQFP (12x12mm) surface mount package defines the physical footprint and pin configuration. Pin-for-pin compatibility is required.

Compliance Standards: RoHS3 compliance status must be maintained for regulatory and supply chain requirements.

Substitute parts meeting all these criteria are functionally equivalent and can replace the R5F2L387CDFP#30 without circuit modification.

Parameter Comparison

Engineering Selection Recommendations

The R5F2L387CDFP#31 is a direct functional equivalent to the R5F2L387CDFP#30. All electrical, memory, peripheral, and package specifications are identical between the two parts.
