80 MHz Cortex-M3 – processing headroom for control and comms
At 80 MHz, the ARM Cortex-M3 core delivers enough throughput to handle a real-time control loop (e.g., a motor FOC or a CAN gateway) alongside protocol stacks for USB and multiple UART/SPI interfaces.
With 64 KB of program Flash and 24 KB of SRAM, this MCU fits firmware images that include a RTOS kernel, a USB stack, and a CANopen or Modbus application layer, but leaves little room for large lookup tables or over-the-air update staging. The 24 KB RAM is shared between stack, heap, and DMA buffers – a design that streams data over USB or CAN will need to budget the buffer pool carefully.
Peripheral set – CAN, USB, and industrial serial interfaces
This makes the part a natural fit for an industrial sensor hub, a motor encoder interface, or a CAN-to-USB gateway. The 16-channel 10-bit ADC (A/D 16x10b) provides enough analog inputs for monitoring multiple sensor signals without an external mux.
Temperature grade and package – industrial deployment in a BGA
The 1.08 V to 1.32 V core supply means a dedicated low-voltage regulator is needed; the I/O bank runs from a separate 3.3 V rail, so level translation is not required for 3.3 V peripherals.
Sourcing reality for an obsolete MCU
Availability and pricing are confirmed only at the time of an RFQ – there is no fixed stock or lead-time number. Buyers should expect to quote against a specific quantity and target date, and to verify date codes and handling history upon receipt.
