Infineon Technologies MB90F549GSPMC-G

Overview

MB90F549GSPMC-G from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with dual FULL-CAN interfaces (CAN V2.0A/B), 256 KB Flash ROM, 6 KB RAM, and QFP-100 package - designed for automotive body control modules requiring real-time CAN communication, deterministic interrupt response (34 sources, 8 priority levels), and mixed-signal integration including 8-channel 10-bit A/D conversion (26.3 µs/channel) and programmable pulse generation.

For engineers reviewing the MB90F549GSPMC-G datasheet, MB90F549GSPMC-G pinout, MB90F549GSPMC-G application, or MB90F549GSPMC-G equivalent, key selection criteria include dual-CAN channel support, Flash-based field-upgradability, 16 MHz max system clock (62.5 ns min instruction time), 81 general-purpose I/O pins, and integrated 16-bit timers with input capture/output compare functionality.

Technical Context

The MB90F549GSPMC-G 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 dual CAN controllers operate independently at up to 1 Mbps with flexible mailbox/FIFO buffering and automatic retransmission on error.

Peripheral subsystems include four 8/16-bit PPG timers, two 16-bit reload timers, one 16-bit free-run timer, eight input capture channels, four output compare channels, full-duplex UART0/UART1 (SCI), and an extended I/O serial interface supporting MSB/LSB-start and internal/external clock synchronization.

Key Specifications

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) designs high-reliability microcontrollers and analog ICs for automotive, industrial, and IoT applications, emphasizing functional safety and long-term supply stability.

The MB90540G/545G series was developed specifically for automotive body electronics and industrial control systems requiring dual CAN 2.0B interfaces, Flash-based field update capability, and robust mixed-signal peripheral integration under extended temperature ranges (−40 °C to +105 °C).

FAQ

What is the maximum operating frequency and corresponding instruction timing for MB90F549GSPMC-G?

The MB90F549GSPMC-G achieves a maximum system clock of 16 MHz using its on-chip PLL (×4 multiplication from a 4 MHz crystal). At this frequency and VCC = 5.0 V, the minimum instruction execution time is 62.5 ns. This timing is confirmed in the official datasheet (Document No. 002-07696 Rev. *B, Page 4) and applies to all core instructions including multiply/divide and bit manipulation operations.

Does MB90F549GSPMC-G support CAN FD or only classical CAN 2.0?

MB90F549GSPMC-G supports only classical CAN 2.0A and 2.0B protocols - not CAN FD. Its dual CAN controllers comply fully with ISO 11898-1:2003, offering message rates up to 1 Mbps, flexible mailbox/FIFO buffering, and automatic retransmission on error. CAN FD features such as variable bit rate and extended data length are absent per the product lineup documentation (Page 5, "FULL-CAN interfaces" section).

How many A/D converter channels does MB90F549GSPMC-G provide, and what are their resolution and timing specs?

MB90F549GSPMC-G integrates an 8-channel successive-approximation A/D converter with selectable 8-bit or 10-bit resolution. Each conversion completes in 26.3 µs when triggered externally, and all channels share common reference pins (AVRH/AVRL). The converter supports simultaneous sampling only in software-controlled sequence mode - no hardware-triggered parallel acquisition is implemented.

Is MB90F549GSPMC-G pin-compatible with other members of the MB90540G/545G series?

Yes - MB90F549GSPMC-G shares identical QFP-100 pinout and electrical characteristics with MB90F543G(S), MB90F546G(S), MB90F548G(S), and MB90F548GL(S) variants. Differences are limited to internal Flash size (256 KB vs. 128 KB), RAM capacity (6 KB vs. 4/8 KB), and clock system configuration (two-clock vs. one-clock), all managed via fuse settings and software initialization - not pin assignment.
