Product details
Overview
LPC2102FBD48,118 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 (including full modem interface), 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 embedded control applications requiring real-time interrupt response and low power.
For engineers reviewing the LPC2102FBD48,118 datasheet, LPC2102FBD48,118 pinout, LPC2102FBD48,118 application, or LPC2102FBD48,118 equivalent, key selection considerations include its 70 MHz ARM7 execution speed, 8 analog input channels with 2.44 µs conversion time, vectored interrupt controller with configurable priorities, ISP/IAP capability for field firmware updates, and support for deep power-down mode with RTC retention (Revision A+).
Technical Context
The LPC2102FBD48,118 implements an ARM7TDMI-S core with dual instruction sets (32-bit ARM and 16-bit Thumb), enabling performance-critical code to run in ARM mode (up to 30% faster than Thumb) while retaining high code density where needed. Its 128-bit wide memory interface and accelerator architecture sustain full-speed 70 MHz operation from on-chip flash.
Peripheral integration includes a vectored interrupt controller (VIC) supporting FIQ, 16 vectored IRQs, and non-vectored IRQs; dual UARTs with fractional baud rate generators and 16-byte FIFOs; and a single 10-bit successive approximation ADC with dedicated result registers per channel to minimize interrupt overhead.

FAQ
What is the maximum operating frequency of the LPC2102FBD48,118?
The LPC2102FBD48,118 achieves a maximum CPU clock frequency of 70 MHz using its on-chip programmable PLL, which accepts an input crystal frequency between 10 MHz and 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 LPC2102FBD48,118 support in-system programming (ISP)?
Yes, the LPC2102FBD48,118 supports full in-system programming via its on-chip bootloader. It allows erasing of individual flash sectors or the entire chip in 100 ms and programming 256 bytes in 1 ms, enabling field firmware updates without removing the device from the target board.
How many analog inputs does the LPC2102FBD48,118 ADC support, and what is its resolution?
The LPC2102FBD48,118 integrates a single 10-bit successive approximation ADC with eight analog input channels (AD0.0–AD0.7). Each channel has a dedicated result register to reduce interrupt overhead, and conversion time is as low as 2.44 µs per sample across the 0 V to 3.3 V measurement range.
What power-saving modes are available on the LPC2102FBD48,118?
The LPC2102FBD48,118 supports Idle mode, Power-down mode (with RTC active), and Deep power-down mode (available in Revision A and higher). In Deep power-down, SRAM and/or RTC can be retained, and wake-up is supported via external interrupt or RTC alarm - enabling ultra-low-power operation for battery-backed applications.
Is the LPC2102FBD48,118 pin-compatible with other members of the LPC210x family?
Yes, the LPC2102FBD48,118 in LQFP48 package shares identical pinout and electrical characteristics with LPC2101FBD48 and LPC2103FBD48. All three devices use the same SOT313-2 footprint, allowing hardware design reuse across memory variants without layout modification.
