FAQ
What is the maximum operating frequency of the LPC2102FHN48,551?
The LPC2102FHN48,551 supports a maximum CPU clock frequency of 70 MHz, achieved via its on-chip programmable PLL with input range of 10 MHz to 25 MHz and 100 µs settling time. This enables high-performance real-time processing while maintaining compatibility with standard crystal oscillators. The 128-bit memory interface and accelerator architecture ensure full-speed execution from flash memory at this clock rate.
Does the LPC2102FHN48,551 support in-system programming (ISP)?
Yes, the LPC2102FHN48,551 includes an on-chip bootloader that supports in-system programming via UART. It allows full chip or sector erase in 100 ms and programming of 256 bytes in 1 ms. This capability enables field firmware updates and eliminates the need for external programming hardware during development or deployment of the LPC2102FHN48,551.
How many analog inputs does the 10-bit ADC in the LPC2102FHN48,551 support?
The LPC2102FHN48,551 integrates a single 10-bit successive approximation ADC with eight analog input channels (AD0.0 to AD0.7). Each channel has a dedicated result register to minimize interrupt overhead, and conversion time is as low as 2.44 µs per channel. Input voltage range is 0 V to 3.3 V, referenced to the VDDA supply.
What power-saving modes are available on the LPC2102FHN48,551?
The LPC2102FHN48,551 supports Idle mode, Power-down mode (with RTC active), and Deep power-down mode (Revision A and higher). In Deep power-down, the device can retain RTC operation and optionally retain SRAM contents. Wake-up is supported via external interrupt or RTC alarm, making it suitable for battery-powered applications requiring ultra-low standby current.
Is the LPC2102FHN48,551 pin-compatible with other members of the LPC2101/02/03 family?
Yes, the LPC2102FHN48,551 is pin-compatible with LPC2101FHN48 and LPC2103FHN48 in the same HVQFN48 package (SOT619-7), sharing identical pin configuration, electrical characteristics, and peripheral mapping. Firmware developed for one variant can run on another with only flash/RAM size adjustments - no PCB or schematic changes are required when upgrading within this package family.
