Product details

Memory map and field-update strategy

256 KB of Flash leaves room for a USB-DFU bootloader plus a full application image. The 4 KB EEPROM block stores calibration coefficients or configuration tokens without wearing the Flash — useful for metering or sensor-trim data that changes infrequently. 36 KB of SRAM is enough for a USB buffer pool and a modest RTOS heap; if your design queues large Ethernet frames or double-buffers a display, budget external SRAM or trim the stack.

Active lifecycle status, ROHS3 compliant. No last-time-buy or NRND notices. Base product number LPC11 covers the family; no successor or direct second source listed by NXP.

Frequently asked questions

What is LPC11U68JBD100K's listed speed (50 MHz) on this component line?

The LPC11U68JBD100K is rated for a 50 MHz core speed. At that clock, the Cortex-M0+ executes single-cycle multiply and delivers enough throughput for USB full-speed packet handling and real-time control loops without stalling the bus.

What compliance documentation does this brand provide for LPC11U68JBD100K?

The LPC11U68JBD100K is ROHS3 compliant. NXP provides the standard RoHS and REACH declarations; no UL or IEC certification is listed in the component record.
