Product details
Overview
MAC7111MAG40 from Freescale Semiconductor is a 32-bit ARM7TDMI-S™ microcontroller designed for automotive embedded control, featuring 256 KB program Flash, 32 KB data Flash, 16 KB SRAM, FlexCAN interface, and operation up to 50 MHz at –40°C to 125°C junction temperature. It integrates eMIOS, DSPI, I²C, eSCI, 10-bit ATD, and supports external bus expansion with 16-bit data/22-bit address bus.
For engineers reviewing the MAC7111MAG40 datasheet, MAC7111MAG40 pinout, MAC7111MAG40 application, or MAC7111MAG40 equivalent, this page delivers verified electrical specs, package mapping (144-pin LQFP), thermal resistance (RθJA = 42°C/W), automotive-grade ESD ratings (HBM: 2 kV), and validated alternative options for engine control unit (ECU), transmission control, and body electronics designs.
Technical Context
The MAC7111MAG40 implements an ARM7TDMI-S core with on-chip PLL enabling system clock scaling up to 50 MHz. Its power architecture includes separate regulated 2.5 V supplies for logic and PLL, plus independent 5 V domains for I/O and analog circuitry (VDDX/VDDA), ensuring noise isolation in mixed-signal automotive environments.
Peripheral integration centers on deterministic real-time control: dual FlexCAN modules (A/B), 16-channel eMIOS for PWM/timing capture, 10-bit ATD with 16 input channels, and configurable DSPI with four chip selects. All GPIO pins support interrupt wake-up from STOP/Pseudo-STOP modes with programmable pulse filtering (3 µs min).

FAQ
What is the maximum operating frequency of the MAC7111MAG40?
The MAC7111MAG40 operates at a maximum system clock frequency of 50 MHz, achieved via its internal PLL. This frequency is fully supported across its specified junction temperature range of –40°C to +125°C and enables deterministic execution of real-time automotive control tasks. The MAC7111MAG40 datasheet confirms this rating under all operating conditions including worst-case voltage (3.15 V) and temperature extremes.
Does the MAC7111MAG40 support external memory expansion?
Yes, the MAC7111MAG40 supports external memory expansion through its 16-bit wide external data bus and 22-bit address bus, as confirmed in the MAC7100 Hardware Specifications document. This capability is explicitly enabled on MAC7111 derivatives and allows connection to external Flash, SRAM, or peripheral ASICs without requiring glue logic in automotive control modules.
What package type is used for the MAC7111MAG40?
The MAC7111MAG40 uses a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch), identified as Case Outline 918–03. This package is thermally optimized for automotive applications with RθJA = 42°C/W on a single-layer board and includes dedicated power/ground pin distribution to maintain signal integrity in noisy environments.
How many CAN interfaces does the MAC7111MAG40 include?
The MAC7111MAG40 integrates two independent FlexCAN modules (labeled CAN_A and CAN_B), each supporting ISO 11898-2 compliant communication up to 1 Mbps. Table 2 of the MAC7100 Hardware Specifications explicitly lists "Yes" for both CAN Modules A and B on the MAC7111 derivative, enabling dual-network gateway functionality.
What is the Flash memory configuration of the MAC7111MAG40?
The MAC7111MAG40 contains 256 KB of program Flash memory and 32 KB of data Flash memory, as documented in Table 2 of the MAC7100 Family Device Derivatives. This split architecture allows separation of executable code from calibration data and runtime variables, supporting field-updatable firmware and adaptive learning algorithms in automotive ECUs.
