Product details
Overview
MB90F543GSPF-GS-BI24 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with Flash ROM, dual FULL-CAN interfaces (CAN 2.0A/B), 128 KB Flash, 6 KB RAM, and QFP-100 package - designed for automotive body control modules requiring real-time CAN communication, deterministic interrupt response, and in-field firmware updates.
For engineers reviewing the MB90F543GSPF-GS-BI24 datasheet, MB90F543GSPF-GS-BI24 pinout, MB90F543GSPF-GS-BI24 application, or MB90F543GSPF-GS-BI24 equivalent, key selection criteria include dual-CAN channel support, 62.5 ns minimum instruction execution time at 16 MHz system clock, 8/10-bit 8-channel ADC with 26.3 µs conversion, and Flash block protection via external programming voltage.
Technical Context
This microcontroller implements the proprietary F2MC-16LX CPU core with 23 addressing modes, 32-bit accumulator for extended precision arithmetic, and enhanced C-language support including system stack pointer and barrel shift instructions. Its dual FULL-CAN controllers provide 16 configurable message buffers per channel with flexible mailbox/FIFO mixing and automatic retransmission on error.
The peripheral subsystem integrates eight 16-bit PPG timers, four 16-bit output compare channels, eight 16-bit input capture channels, two 16-bit reload timers, and dual UARTs (SCI) supporting up to 2 Mbps synchronous transfer - all synchronized to a programmable PLL-derived system clock (1×–4× or ÷2 of crystal input).

FAQ
What is the maximum CAN bit rate supported by MB90F543GSPF-GS-BI24?
The device supports CAN communication up to 1 Mbps per channel, compliant with ISO 11898-1 (CAN 2.0A/B). This maximum rate assumes proper termination, cable length ≤40 m, and use of recommended CAN transceivers such as TJA1042 or SN65HVD230. Bit timing registers allow fine-tuning for network-specific propagation delays.
Does MB90F543GSPF-GS-BI24 support in-system programming of Flash memory?
Yes - it supports full in-system programming via on-chip Flash algorithm commands (Write, Erase, Erase-Suspend, Resume), with completion flags and block-level protection controlled by external VPP voltage. No external programmer is needed; updates can be performed through UART or CAN using customer-defined bootloader code.
How many general-purpose I/O pins are available on the QFP-100 package?
The QFP-100 package provides 81 general-purpose I/O ports, all individually configurable as input, output, or peripheral function (e.g., UART, CAN, timer, ADC). Each port supports bit-wise direction control and schmitt-trigger input thresholds, enabling direct connection to noisy automotive sensors without external conditioning.
Is the MB90F543GSPF-GS-BI24 qualified for automotive AEC-Q100 Grade 1?
Yes - it is qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C ambient), with guaranteed operation from −40 °C to +105 °C junction temperature. The qualification includes HTOL, TC, UHAST, and ESD testing per Rev. D requirements, and the device carries full PPAP documentation for Tier 1 automotive suppliers.
