The NXP LPC4317JET100E is a 32-bit dual-core microcontroller built around an ARM Cortex-M4 and a Cortex-M0, clocked at 204 MHz.
204 MHz dual-core — what it buys you
The Cortex-M4 handles the main control loop and DSP-style math at 204 MHz, while the Cortex-M0 runs housekeeping tasks without stealing cycles from the M4.
Memory and storage budget
1 MB of Flash is sized for a full communication stack (CANopen, TCP/IP offload, or a small file system) plus the application firmware. The 16 KB EEPROM block stores calibration constants, node IDs, and fault logs without needing an external serial EEPROM — one fewer BOM line. 136 KB of RAM (organized as 136K x 8) supports moderate-sized data buffers for Ethernet or image capture from a parallel camera sensor via the EBI.
That means it remains in the current portfolio with no announced last-time-buy or discontinuation window.
