FAQ
What is the maximum operating frequency and supply voltage range for the M30879FKAGP#U3?
The M30879FKAGP#U3 operates at up to 32 MHz with VCC1 between 4.2 V and 5.5 V, or at 24 MHz with VCC1 between 3.0 V and 5.5 V. VCC2 must be set between 3.0 V and VCC1. These ranges are defined in Renesas REJ03B0127-0151 Rev.1.51 Section 1.1.2 and validated for the PLQP0100KB-A package used by M30879FKAGP#U3.
Does the M30879FKAGP#U3 support dual CAN 2.0B interfaces, and how are they implemented?
Yes, the M30879FKAGP#U3 implements two fully independent CAN 2.0B modules (CAN0 and CAN1), each with 16 message slots, identifier masking, and automatic retransmission. Pins CAN0IN/CAN0OUT (P8_3/P8_2) and CAN1IN/CAN1OUT (P9_5/P9_6) are physically separate and concurrently active - confirmed in Table 1.4 and Figure 1.2 of the M32C/87 Group datasheet for M32C/87A variants.
What package type and pin count does the M30879FKAGP#U3 use?
The M30879FKAGP#U3 uses a 100-pin LQFP package designated PLQP0100KB-A (14 × 14 mm, 0.5 mm pitch), as specified in Table 1.6 and Figure 1.4 of Renesas REJ03B0127-0151 Rev.1.51. This is distinct from the 144-pin variant used by M3087BFKAGP and confirms full pin compatibility within the M32C/87A 100-pin family.
How much on-chip RAM and flash memory does the M30879FKAGP#U3 include?
The M30879FKAGP#U3 integrates 31 KB of on-chip RAM and 768 KB of flash program memory plus an additional 4 KB of dedicated data flash memory - all accessible without external memory interface. This configuration is explicitly listed in Table 1.6 under "M32C/87 Group (2)" for part number M30879FKAGP in the Renesas documentation.
Is the M30879FKAGP#U3 pin-compatible with other M32C/87A variants like M30879FLAGP?
No - M30879FKAGP#U3 (100-pin LQFP) is not pin-compatible with M30879FLAGP (also 100-pin LQFP but with 1 MB flash). While both share the PLQP0100KB-A package and identical pinout, differences in flash size and internal memory mapping require validation of boot vector, interrupt vector table, and peripheral register initialization - making them functionally compatible but not guaranteed drop-in replacements without firmware review.
