Product details

The 164 I/O pins support parallel LCD interfaces and external bus expansion.

Connectivity and peripherals — single-chip gateway capability

The EBI/EMI interface can connect to external SRAM, NOR Flash, or LCD controllers, expanding the memory map beyond the on-chip resources. The motor control PWM and quadrature encoder interface (QEI) are there for servo or BLDC drive stages, though the BGA package means the power-stage routing needs careful signal-integrity planning. Data converters include eight 10-bit ADC channels and one 10-bit DAC.

The product status is Active. Standard sourcing through distribution applies.

Frequently asked questions

Is LPC4357JET256,551 obsolete or EOL?
