Product details
Overview
MB90F543GSPF-GS-9003 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with dual FULL-CAN interfaces (CAN V2.0A/B), 128 KB Flash ROM, 6 KB RAM, and 81 general-purpose I/O ports. It operates at up to 16 MHz system clock (via on-chip PLL ×4), achieves 62.5 ns minimum instruction execution time, and targets automotive body control modules requiring CAN-based distributed sensing and actuation.
For engineers reviewing the MB90F543GSPF-GS-9003 datasheet, MB90F543GSPF-GS-9003 pinout, MB90F543GSPF-GS-9003 application, or MB90F543GSPF-GS-9003 equivalent, key selection criteria include dual-CAN timing determinism, Flash reprogrammability in-circuit, 10-bit A/D conversion with 26.3 µs per channel, and support for external bus expansion up to 16 Mbytes.
Technical Context
The MB90F543GSPF-GS-9003 implements the proprietary F2MC-16LX CPU core with 32-bit accumulator, 23 addressing modes, and enhanced C-language support including system stack pointer and barrel shift instructions. Its interrupt subsystem delivers 8 priority levels and 34 interrupt sources, including dedicated CAN message buffers and EI2OS-triggered service requests.
It integrates two independent FULL-CAN controllers compliant with ISO 11898-1:2003, each supporting flexible mailbox/FIFO mixing, automatic retransmission, remote frame response, and programmable acceptance filtering (full-bit compare/mask or dual partial masks). The peripheral set includes 8/10-bit 8-channel A/D converter, four 8/16-bit PPG timers, dual 16-bit reload timers, and UART0/UART1 with synchronous/asynchronous modes up to 2 Mbps.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-CAN microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144 | ARM Cortex-M4F core, single CAN FD channel, 512 KB Flash, 64 KB RAM, AEC-Q100 Grade 1 | Supports CAN FD (5 Mbps) but lacks second native CAN; requires software CAN stacking for dual-node routing | Preferred when CAN FD bandwidth or ASIL-B functional safety certification is mandatory |
| Renesas RL78/F14 | RL78 core, single CAN 2.0B channel, 256 KB Flash, 32 KB RAM, −40 °C to +125 °C | No dual-CAN hardware; relies on time-sliced CAN sharing; lower interrupt latency but reduced concurrent message throughput | Selected for cost-sensitive, single-bus applications where external CAN controller offload is acceptable |

FAQ
Does MB90F543GSPF-GS-9003 support CAN FD?
No. MB90F543GSPF-GS-9003 implements FULL-CAN compliant with ISO 11898-1:2003 (CAN V2.0A/B), supporting up to 1 Mbps classical CAN only. It does not include CAN FD physical layer or protocol enhancements such as flexible data-rate or extended payload length.
What is the maximum external bus clock frequency supported?
The external bus interface supports up to 16 MHz system clock (fsys) with wait-state configuration. Access timing is defined by RDY signal assertion and WRH/WRL strobes; maximum sustained throughput depends on external memory access latency and wait-state settings per Cypress Document 002-07696 Section 4.3.
Can the 32 kHz sub-clock be used for RTC functionality?
Yes. The 32 kHz sub-clock is explicitly designated for low-power operation and can drive a software-implemented real-time counter. While no dedicated RTC peripheral is integrated, the 16-bit free-run timer and interrupt-on-overflow capability allow accurate timekeeping with <1 ppm drift when paired with a precision 32.768 kHz crystal on X0/X1.
Is the Flash memory capable of EEPROM-like byte-write operations?
No. Flash programming requires page/sector erase before write; the smallest erasable unit is a block (size unspecified in public documentation). Byte-level updates must be managed in RAM with shadow copy and block rewrite-no hardware EEPROM emulation or wear-leveling engine is present.
