Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
RH850/F1L	32-bit RXv2 core, 1.5 MB Flash, single CAN FD channel, integrated CAN transceiver driver	Higher performance for complex motor control; lacks dual classical CAN required for legacy vehicle architectures	Choose when migrating to CAN FD and requiring >200 DMIPS; not drop-in for existing MB90F546G designs
TC1766	TriCore 32-bit CPU, 2 MB Flash, dual CAN FD, embedded Ethernet MAC, no Flash block protection	Targeted at high-end powertrain ECUs; higher cost and complexity than body-control requirements	Prefer for new designs needing Ethernet connectivity; unsuitable where cost-sensitive dual-CAN 2.0B is sufficient

FAQ

What is the maximum baud rate supported by the CAN interfaces on MB90F546GSPF-G-ER?

The dual CAN controllers support bit rates up to 1 Mbps per channel, compliant with ISO 11898-1 V2.0A/B specifications. Baud rate configuration is achieved via programmable bit timing registers (BTR0/BTR1), allowing precise tuning for network topology and oscillator tolerance. No external transceiver is required for physical layer interfacing.

Does MB90F546GSPF-G-ER support in-system programming of its Flash memory?

Yes, the device supports full in-system programming via its on-chip Flash algorithm, including Write, Erase, Erase-Suspend, and Erase-Resume commands. Programming is initiated through dedicated command registers, and completion is signaled by a status flag. Block protection requires application of external Vpp voltage during write/erase operations.

How many general-purpose I/O pins does MB90F546GSPF-G-ER provide?

The microcontroller provides 81 general-purpose I/O ports, all individually configurable as input, output, or peripheral function (e.g., UART, CAN, ADC). Each port supports push-pull drive strength and Schmitt-trigger input thresholds, with bit-wise direction control via dedicated data direction registers (DDR).

What low-power modes are available on MB90F546GSPF-G-ER?

Five low-power modes are implemented: Sleep (CPU clock stopped), Stop (oscillation halted), CPU Intermittent Operation (periodic wake-up), Watch (sub-clock active only), and Hardware Stand-by (minimal current draw with external interrupt wake-up). The 32 kHz sub-clock remains functional in Watch mode for RTC or periodic CAN wake-up events.
