The 200 KB SRAM is split across both cores — enough for a modest control algorithm and a CANopen or Modbus stack without external memory for many designs. The 118 I/O in a 180-TFBGA 12×12 mm package packs a lot of signal routing into a compact footprint — plan for a four-layer PCB to route the EBI/EMI and CANbus traces cleanly. ## 204 MHz — where the speed matters The Cortex-M4 runs at 204 MHz. The Cortex-M0 handles deterministic tasks like PWM update or UART byte streaming without jitter from the M4's cache misses. ## ROMless — plan for external code storage This part has no internal Flash — program memory type is ROMless. All firmware must reside in external NOR Flash or SRAM accessed through the EBI/EMI interface. That adds a serial or parallel Flash IC to the BOM and requires careful layout of the memory bus for signal integrity at 204 MHz. The trade-off is flexibility: you can size the external memory to the application and update firmware in the field without pre-programming the MCU. Product status is Active — NXP continues to manufacture and support the LPC43S20FET180K.","metaTitle":"NXP LPC43S20FET180K ARM Cortex-M4/M0 MCU, 204 MHz","metaDescription":"NXP LPC43S20FET180K dual-core ARM Cortex-M4/M0 MCU at 204 MHz, 200 KB SRAM, 118 I/O, -40°C to 85°C, 180-TFBGA.
