FAQ
What is the flash memory capacity and endurance rating of the M30855FJGP#U5?
The M30855FJGP#U5 contains 320 KB of on-chip flash memory. Its program/erase endurance is rated at 100 cycles across the entire memory space. Programming can be performed at either 3.3 V ±0.3 V or 5.0 V ±0.5 V, supporting flexible system-level voltage design. This flash configuration is consistent across all F-version M32C/85 devices with 'J' ROM code.
Does the M30855FJGP#U5 support CAN FD or only classical CAN 2.0B?
The M30855FJGP#U5 supports only CAN 2.0B (ISO 11898-1), not CAN FD. Its dual CAN modules implement full mailbox-based message objects, acceptance filtering, and error confinement per the 2.0B specification. CAN FD frame format, bit rate switching, and extended data length are not supported in the M32C/85 hardware architecture.
What is the maximum operating frequency and corresponding instruction cycle time for the M30855FJGP#U5?
The M30855FJGP#U5 achieves a minimum instruction execution time of 31.3 ns when operating at 32 MHz BCLK with VCC1 = 4.2–5.5 V. At 24 MHz BCLK and VCC1 = 3.0–5.5 V, the minimum cycle time is 41.7 ns. These values are measured under specified voltage and temperature conditions and reflect the performance of the M32C/80 CPU core.
How many analog input channels does the M30855FJGP#U5 support, and what is the resolution?
The M30855FJGP#U5 integrates a single 10-bit successive-approximation A/D converter with 26 input channels. This count applies specifically to the 100-pin package variant (e.g., M30855FJGP#U5); the 144-pin version supports up to 34 channels. All channels share the same AVcc/AVss reference domain and support software-triggered or timer-triggered conversions.
Is the M30855FJGP#U5 pin-compatible with other members of the M32C/85 family?
The M30855FJGP#U5 is pin-compatible with other 100-pin LQFP variants in the M32C/85 family, including M30853FJGP#U5 (256 KB flash) and M30857FJGP#U5 (512 KB flash), provided identical package type (PLQP0100KB-A) and revision level. Pin functions, electrical characteristics, and timing parameters remain consistent across these flash-density variants.
