The LPC4327JBD144E pairs an ARM Cortex-M4 for number-crunching and DSP with a Cortex-M0 for housekeeping or real-time I/O. At 204 MHz, the M4 handles motor-control FOC loops or audio processing while the M0 manages CANbus traffic and GPIO toggling without stealing cycles. That split keeps deterministic response on the fieldbus side even when the main core is busy with a floating-point filter.
Memory map and peripheral set
1 MB of Flash and 136 KB of SRAM give this part room for a full protocol stack plus a moderate application image — think a CANopen node with a web server or a USB-hosted data logger. The 16 KB EEPROM emulation block holds calibration constants or boot counters without wearing the main Flash. The 8-channel 10-bit ADC and single 10-bit DAC cover basic analog sensing and setpoint output.
Operating temperature range is -40 to 105 °C. Supply voltage range is 2.2 to 3.6 V.
NXP lists this part as Active.
