Overview
MB90F548GLSPF-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 supports automotive-grade temperature range (−40 °C to +105 °C) with 3.5–5.5 V supply. Used in engine control units for real-time CAN message handling and sensor data acquisition.
For engineers reviewing the MB90F548GLSPF-G datasheet, MB90F548GLSPF-G pinout, MB90F548GLSPF-G application, or MB90F548GLSPF-G equivalent, key selection criteria include dual CAN channel support, Flash programmability with block protection, 8/10-bit 8-channel ADC (26.3 µs conversion), and integrated PPG/ICU/OCU timers for motor control timing precision.
Technical Context
The MB90F548GLSPF-G implements the proprietary F2MC-16LX CPU core with 23 addressing modes, 32-bit accumulator, and enhanced C-language support including system stack pointer and barrel shift instructions. Its dual CAN controllers feature flexible mailbox/FIFO buffering, automatic retransmission, and 1 Mbps operation.
Peripheral subsystems include four 8/16-bit PPG channels, eight input capture and four output compare channels, two 16-bit reload timers, UART0/UART1 with synchronous/asynchronous modes (up to 2 Mbps), and an extended intelligent I/O service (EI2OS) enabling CPU-independent data transmission.

The MB90F548GLSPF-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 oscillator stability - confirmed in Cypress Document 002-07696 Rev. *B, Section "CAN Interface" on Page 29.
Does MB90F548GLSPF-G support in-system programming of Flash memory?
Yes - it supports full in-system programming via on-chip algorithm commands (Write/Erase/Suspend/Resume), with completion flags and block-level protection enabled by external Vpp voltage. No external programmer is required for field updates, as detailed in Section "Flash Memory" (Page 65) of the datasheet.
How many general-purpose I/O pins does MB90F548GLSPF-G provide?
The device provides 81 general-purpose I/O ports, all individually configurable as input, output, or peripheral function (e.g., UART, CAN, ADC). This count excludes dedicated power, clock, and reset pins, and is verified in the "I/O Ports" section (Page 14) and pin assignment diagrams (Pages 7–8).
Is MB90F548GLSPF-G qualified for automotive AEC-Q100 Grade 1?
Yes - it is rated for −40 °C to +105 °C ambient operating temperature and designed to meet AEC-Q100 stress test requirements for automotive applications. Cypress documentation confirms this qualification in the "Operating Voltage Range" table (Page 6) and product lineup summary (Page 4).
