MB90F548GPF-G from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with dual FULL-CAN interfaces (CAN 2.0A/B), 128 KB Flash ROM, 4 KB RAM, and 100-pin LQFP package. It operates at up to 16 MHz system clock (via on-chip PLL ×4), delivers 62.5 ns minimum instruction execution time, and targets automotive body control modules requiring CAN-based distributed networking and real-time I/O management.
For engineers reviewing the MB90F548GPF-G datasheet, MB90F548GPF-G pinout, MB90F548GPF-G application, or MB90F548GPF-G equivalent, key selection criteria include dual-CAN channel support, Flash programmability with block protection, 8/10-bit 8-channel ADC with 26.3 µs conversion, and integrated 16-bit I/O timer with 8-input capture/4-output compare channels.
Technical Context
The MB90F548GPF-G implements the proprietary F2MC-16LX CPU core with 23 addressing modes, 32-bit accumulator for extended precision arithmetic, and enhanced C-language support via system stack pointer and barrel shift instructions. Its interrupt subsystem supports 8 priority levels and 34 sources, including delayed-interrupt generation for task switching.
Dual FULL-CAN controllers provide flexible mailbox/FIFO message buffering, automatic retransmission, remote frame response, and acceptance filtering with full-bit compare/mask options. The external bus interface supports up to 16 Mbytes address space with selectable 8-/16-bit data width and hardware handshaking (HRQ/HAK/RDY).

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, single CAN FD channel, 1 MB Flash, 125 °C rating | Higher performance and CAN FD support but lacks dual classical CAN and requires external CAN transceivers | Select when migrating to CAN FD or requiring >16 MHz deterministic processing; not drop-in compatible |
| MC9S12XEQ512 | 16-bit HCS12X core, single CAN 2.0B, 512 KB Flash, no embedded PLL | Legacy toolchain support and mature automotive qualification but no dual CAN or Flash block protection | Select for brownfield designs with existing S12X software; requires external clock multiplier for >8 MHz operation |
Compared with RH850/F1L and MC9S12XEQ512, the MB90F548GPF-G uniquely balances dual classical CAN integration, Flash security features, and deterministic 16-bit real-time I/O - making it optimal for cost-sensitive, CAN-centric body electronics where CAN FD migration is not yet required.

FAQ
What is the maximum CAN bit rate supported by MB90F548GPF-G?
The MB90F548GPF-G supports CAN communication up to 1 Mbps, compliant with ISO 11898-1 (CAN 2.0A/B). This maximum rate is achievable with proper bus termination, transceiver selection, and timing configuration of the CAN controller's baud rate prescaler and segment registers.
Does MB90F548GPF-G include hardware support for Flash memory write protection?
Yes - MB90F548GPF-G provides hardware-assisted Flash block protection activated by applying an external programming voltage (Vpp) to the MD0–MD2 pins during write/erase operations. This prevents accidental overwrites and enables secure boot code partitioning.
Can the 16-bit I/O timer operate independently of CPU execution?
Yes - the 16-bit I/O timer supports autonomous operation: input capture timestamps external events without CPU polling, and output compare generates PWM or periodic interrupts based on free-run timer matches, all managed by dedicated hardware state machines.
Is the MB90F548GPF-G qualified for automotive AEC-Q100 Grade 2?
Yes - MB90F548GPF-G is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C), with validated electrical characteristics, ESD immunity (≥2 kV HBM), and reliability testing per JEDEC standards, as documented in Cypress datasheet 002-07696 Rev. *B.
