Tri-core architecture — what the 204 MHz means for the BOM
The LPC4370FET256E: Operating temperature spans -40°C to 85°C. Supply range is 2.2 V to 3.6 V. Connectivity includes CANbus, Ethernet, USB, I²C, SPI, UART/USART, and an external bus interface (EBI/EMI) — enough protocol support to serve as a fieldbus gateway or a data concentrator between a PLC backplane and a higher-level network. The internal oscillator and brown-out detect reset reduce external component count on the board.
Package and integration notes
Housed in a 256-LBGA (17x17 mm) package — surface-mount only, no through-hole option. The 1.0 mm ball pitch is manageable with standard SMT assembly; no via-in-pad required unless the board density demands it. The 164 I/O lines fan out across the BGA, so route the EBI/EMI address and data buses with matched trace lengths if using parallel NOR Flash at speed. The internal POR and brown-out detect eliminate the need for an external supervisor IC in most designs.
