That core speed puts it in the upper tier of Cortex-M3 parts — enough headroom to run a real-time control loop alongside a TCP/IP stack without stalling the scheduler. The 1 MB Flash can hold a full application plus a fallback bootloader for field updates; the 136 KB RAM supports moderate buffering for Ethernet frames or CAN message queues. The 164 general-purpose I/O lines, combined with the internal oscillator and brown-out detection, reduce external component count in a motor-drive or PLC I/O module. Rated for -40°C to 105°C ambient, the LPC18S57JET256E operates from a 2.2 V to 3.6 V supply range. The 256-LBGA package (17x17 mm) requires careful PCB layout for BGA routing.","metaTitle":"LPC18S57JET256E ARM Cortex-M3 MCU, 180MHz, 1MB Flash, -40 to 105°C","metaDescription":"LPC18S57JET256E from NXP: 32-bit ARM Cortex-M3 MCU at 180MHz with 1MB Flash, 136K x 8 RAM, CAN/Ethernet/USB, -40 to 105°C.
