The 512 KB Flash and 200 KB SRAM support an RTOS heap and protocol stacks. The 16 KB EEPROM stores calibration constants. A 12-channel 12-bit ADC handles sensor feedback.
The 180-TFBGA package measures 12x12 mm. This BGA footprint requires a PCB with microvias and reflow soldering with x-ray inspection.
Active. The lifecycle status is Active, meaning NXP continues to manufacture and supply this part for new designs.
180-TFBGA, 12x12 mm body, 0.5 mm ball pitch.
The order code LPC54605J512ET180K is the specific variant with 180 MHz speed and 180-TFBGA package; LPC54605J512ET180 is a different suffix that may indicate a different package or temperature grade — verify the exact suffix against your BOM before substituting.
