Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Renesas RL78/F13 | Lower Flash (64KB same), but 32-pin QFN vs. 64-pin QFP; no integrated CAN controller | Requires external CAN transceiver and additional level-shifting circuitry | Preferred for space-constrained non-CAN nodes where cost-per-mm² dominates |
| NXP S9KEAZ128AMLH | ARM Cortex-M0+ core, 128KB Flash, 16KB RAM; CAN 2.0B supported but only 16 message objects | Lacks hardware windowed watchdog and AEC-Q100 Grade 2 qualification | Suitable for lower-risk cabin applications where ASIL-B compliance is not required |
Compared with RL78/F13 and S9KEAZ128AMLH, the MB90F462APF-G-SPE1 delivers higher CAN message buffer depth, integrated voltage regulation, and full AEC-Q100 Grade 2 qualification-making it optimal for under-hood body control where thermal robustness and bus reliability are critical.

FAQ
Does MB90F462APF-G-SPE1 support JTAG debugging?
Yes, the MB90F462APF-G-SPE1 supports JTAG-based on-chip debugging via dedicated TCK/TMS/TDI/TDO pins. Debug access enables real-time register inspection, breakpoint setting, and flash programming verification without halting peripheral operation.
What is the maximum ADC sampling rate achievable with all 16 channels enabled?
With all 16 channels scanned sequentially in burst mode, the MB90F462APF-G-SPE1 achieves a maximum effective sampling rate of 80 kSPS. This assumes 10-bit resolution, internal reference, and 1.25 µs per conversion including channel switching overhead.
Is the CAN controller compatible with ISO 11898-2 physical layer?
No-the MB90F462APF-G-SPE1 contains only the CAN protocol controller (ISO 11898-1). An external ISO 11898-2 compliant transceiver (e.g., Infineon TLE6250) is required for physical layer signaling on the CAN bus.
Can the on-chip voltage regulator power external 3.3V peripherals?
No-the internal 3.3V regulator supplies only the MCU's core logic and analog blocks. Its output is not accessible externally; external 3.3V peripherals must be powered from a separate regulated source to avoid loading-induced voltage droop.
