ARM7TDMI-S at 50 MHz — what the core means for your control loop
The MAC7131VVF50R2 is a 32-bit ARM7TDMI-S microcontroller from the MAC71xx family, clocked at 50 MHz with 512 KB of Flash program memory and 32K x 8 of both RAM and EEPROM.
The supply voltage is 2.35 V to 2.75 V.
The 32K x 8 RAM is adequate for data buffers and stack, but heavy use of the CAN or EBI may require careful memory budgeting. The integrated DMA controller offloads data transfers from the CPU, which helps at 50 MHz when handling multiple communication channels simultaneously.
The part is RoHS non-compliant — verify your exemption or accept the lead-bearing finish if your application allows it. For BOM planning, this is a stable line without imminent obsolescence risk.
