Product details
Overview
LPC2102FBD48,151 from NXP Semiconductors is a 32-bit ARM7TDMI-S microcontroller in LQFP48 package with 16 kB flash, 4 kB SRAM, 10-bit 8-channel ADC, dual UARTs (one with full modem control), two Fast I²C buses (400 kbit/s), SPI/SSP, and 32 fast 5 V-tolerant GPIO pins. It operates at up to 70 MHz via on-chip PLL and targets compact industrial control, protocol conversion, and medical sensor interfaces.
For engineers reviewing the LPC2102FBD48,151 datasheet, LPC2102FBD48,151 pinout, LPC2102FBD48,151 application, or LPC2102FBD48,151 equivalent, key selection factors include its 70 MHz ARM7 performance with Thumb/ARM mode flexibility, 5 V-tolerant I/O across 31 pins, integrated RTC with independent power, ISP/IAP capability for field firmware updates, and support for real-time debugging via EmbeddedICE-RT.
Technical Context
The LPC2102FBD48,151 implements an ARM7TDMI-S core with dual instruction sets (32-bit ARM and 16-bit Thumb), enabling up to 30 % higher interrupt service performance in ARM mode versus Thumb. Its 128-bit wide memory interface and accelerator architecture sustain full-speed 70 MHz execution from on-chip flash.
It integrates a vectored interrupt controller (VIC) supporting configurable priorities across FIQ, 16 vectored IRQs, and non-vectored IRQs; a pin connect block enabling dynamic peripheral-to-pin mapping; and accelerated GPIO with byte-addressable registers, mask registers, and single-instruction port writes - all optimized for deterministic real-time I/O handling.

FAQ
What is the maximum operating frequency of the LPC2102FBD48,151?
The LPC2102FBD48,151 achieves a maximum CPU clock frequency of 70 MHz using its on-chip programmable PLL, which accepts input frequencies from 10 MHz to 25 MHz and settles in 100 µs. This frequency is sustained across the full −40 °C to +85 °C industrial temperature range with appropriate decoupling and power supply stability.
Does the LPC2102FBD48,151 support in-system programming (ISP)?
Yes, the LPC2102FBD48,151 includes an on-chip bootloader that enables in-system programming via UART0. It supports single-sector or full-chip erase in 100 ms and programming of 256 bytes in 1 ms, allowing field firmware updates without removing the device from the PCB.
How many analog inputs does the 10-bit ADC in the LPC2102FBD48,151 support?
The LPC2102FBD48,151 integrates a single 10-bit successive approximation ADC with eight analog input channels (AD0.0 through AD0.7), each mapped to dedicated GPIO pins (P0.22 through P0.26 and P0.10–P0.12). Each channel has its own result register to reduce interrupt overhead during burst conversions.
Is the LPC2102FBD48,151 pin-compatible with other members of the LPC2101/02/03 family in LQFP48 package?
Yes, the LPC2102FBD48,151 is fully pin-compatible with LPC2101FBD48 and LPC2103FBD48 in the LQFP48 package (SOT313-2). All share identical pin functions, electrical characteristics, and peripheral register mapping - only flash (8/16/32 kB) and SRAM (2/4/8 kB) capacities differ.
What debug interface does the LPC2102FBD48,151 provide?
The LPC2102FBD48,151 features an EmbeddedICE-RT debug interface compliant with ARM JTAG standard, supporting real-time debugging via TRST/TMS/TCK/TDI/TDO pins.
