Overview
MAC7131MVF40 from Freescale Semiconductor is a 32-bit ARM7TDMI-S™ microcontroller designed for automotive embedded control, featuring 1 MB program Flash, 32 KB data Flash, 48 KB RAM, FlexCAN interface, and operation up to 50 MHz at –40°C to 125°C junction temperature. It integrates eDMA, eMIOS, dual DSPI, dual eSCI, I²C, 10-bit ATD with 16 channels, and supports external 16-bit bus expansion.
For engineers reviewing the MAC7131MVF40 datasheet, MAC7131MVF40 pinout, MAC7131MVF40 application, or MAC7131MVF40 equivalent, this page delivers verified electrical specs, package mapping (144-pin LQFP), thermal resistance data (RθJA = 42°C/W), automotive-grade ESD ratings (HBM: 2 kV), and validated alternative parts for scalable automotive MCU selection.
Technical Context
The MAC7131MVF40 implements an ARM7TDMI-S™ core with 32-bit internal data paths between CPU, eDMA, memory, and peripherals. It uses a PLL to scale system clock up to 50 MHz while maintaining compatibility across the MAC7100 family's pin-compatible derivatives.
It supports dual FlexCAN modules (A/B), dual DSPI controllers with four chip selects, dual eSCI interfaces, and a 10-bit ATD module with 16 input channels - all sharing bidirectional GPIO pins with interrupt capability for wake-up from low-power modes including STOP and Pseudo STOP.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAC7141MVF40 | Same 144-pin LQFP package and core, but adds 208-pin BGA option and enhanced external bus (22 address/16 data lines vs. 16/16 on MAC7131) | Required when external memory expansion beyond 1 MB Flash is needed (e.g., map-based navigation storage) | Select MAC7141MVF40 only if external SDRAM or NOR flash interface is mandatory; otherwise MAC7131MVF40 offers optimal cost/performance balance. |
| S912XDP512J1MALR | 16-bit S12X core (not ARM7), 512 KB Flash, 32 KB RAM, same 144-pin LQFP, AEC-Q100 Grade 1, but lacks eDMA and has single CAN | Suitable for legacy S12X migration paths or cost-sensitive non-safety-critical body modules where ARM7 toolchain adoption is not required | Choose S912XDP512J1MALR only for brownfield designs constrained by S12X software investment; MAC7131MVF40 provides superior throughput and peripheral integration for new development. |

FAQ
What is the maximum operating frequency of the MAC7131MVF40?
The MAC7131MVF40 operates at a maximum system clock frequency of 50 MHz, achieved via its integrated PLL. This frequency is fully supported across its full operating temperature range of –40°C to +125°C junction temperature, enabling deterministic real-time execution for automotive control loops. The MAC7131MVF40 achieves this while maintaining full functionality of all on-chip peripherals including dual FlexCAN, DSPI, and ATD modules.
Does the MAC7131MVF40 include an internal voltage regulator?
Yes, the MAC7131MVF40 includes an internal voltage regulator that generates the 2.5 V digital core supply (VDD2.5) and 2.5 V PLL supply (VDDPLL) from the main I/O supply (VDDX = 3.15–5.5 V). This allows single-rail 5 V system design. The regulator supports Full Performance, Reduced Power, and Shutdown modes - with output voltages tightly regulated at 2.45–2.75 V in active modes, as specified in the MAC7100 Hardware Specifications Rev. 1.2.
What package type and pin count does the MAC7131MVF40 use?
The MAC7131MVF40 is packaged in a 144-pin LQFP (20 mm × 20 mm, 0.5 mm pitch, case outline 918–03), with 112 usable general-purpose I/O pins. This matches the pinout of other MAC7100 family members like MAC7141MVF40, enabling hardware scalability. Pin assignments are documented in Section 4.8 ("MAC7131 Pin Diagram") of the MAC7100 Hardware Specifications Rev. 1.2.
Is the MAC7131MVF40 qualified for automotive applications?
Yes, the MAC7131MVF40 is AEC-Q100 Grade 1 qualified for automotive use, with guaranteed operation from –40°C to +125°C junction temperature. It features HBM ESD immunity of ±2000 V, latch-up immunity of ±200 mA at 27°C, and is designed to meet stringent automotive reliability and longevity requirements - making it suitable for powertrain, chassis, and body control applications.
How many CAN interfaces does the MAC7131MVF40 support?
The MAC7131MVF40 integrates two independent FlexCAN 2.0B modules (CAN_A and CAN_B), each supporting full CAN protocol compliance including identifier masking, message buffering, and error handling. Both modules operate concurrently and can be configured for different bit rates - enabling segregated communication domains such as powertrain CAN and chassis CAN within a single ECU.
