Product details

1 MB Flash and 136K RAM — firmware budget

1 MB of Flash is enough for a full Ethernet/IP or Modbus TCP stack plus application code, without squeezing into a smaller bank. The 136K x 8 RAM supports multiple packet buffers and a decent heap for dynamic allocation. If your design runs a GUI on an external display, the EBI/EMI interface maps the frame buffer off-chip without stealing internal RAM.

Connectivity and peripherals — one chip, many buses

The motor control PWM and QEI inputs are wired for servo or BLDC drive feedback.

Frequently asked questions
