Product details
Overview
LPC2101FBD48,151 from NXP Semiconductors is a 16-bit/32-bit ARM7TDMI-S microcontroller in LQFP48 package with 8 kB flash, 2 kB SRAM, 10-bit 8-channel ADC (2.44 µs conversion), dual UARTs (16C550-compatible), and two Fast I²C buses (400 kbit/s), designed for compact industrial control and protocol converter applications.
For engineers reviewing the LPC2101FBD48,151 datasheet, LPC2101FBD48,151 pinout, LPC2101FBD48,151 application, or LPC2101FBD48,151 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and confirmed alternative parts - all aligned to the official NXP LPC2101/02/03 Rev. 04 datasheet.
Technical Context
The LPC2101FBD48,151 implements an ARM7TDMI-S core with dual instruction sets (32-bit ARM and 16-bit Thumb), enabling up to 30% higher interrupt performance in ARM mode versus Thumb while retaining code density advantages. Its 128-bit memory interface and accelerator support 70 MHz CPU operation from a programmable on-chip PLL (10–25 MHz input, 100 µs settling).
Peripheral integration includes a vectored interrupt controller with configurable priorities, accelerated GPIO (ARM local bus mapping, byte-addressable registers), and a dedicated 10-bit ADC with per-channel result registers to minimize interrupt overhead - all optimized for deterministic real-time response in embedded gateways and medical sensor interfaces.

FAQ
What is the maximum operating frequency of the LPC2101FBD48,151?
The LPC2101FBD48,151 achieves a maximum CPU clock speed of 70 MHz using its on-chip 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, enabling deterministic real-time execution in time-critical applications such as motor control and sensor fusion.
Does the LPC2101FBD48,151 support in-system programming (ISP)?
Yes, the LPC2101FBD48,151 supports full in-system programming via its UART0 interface using the on-chip bootloader. It allows sector-by-sector or full-chip flash erase (100 ms) and 256-byte programming (1 ms), enabling field firmware updates without removing the device from the PCB - a key capability for deployed industrial and medical equipment.
How many analog inputs does the ADC in the LPC2101FBD48,151 support?
The LPC2101FBD48,151 integrates a single 10-bit successive approximation ADC with eight analog input channels (AD0.0 to AD0.7), each mapped to dedicated GPIO pins (P0.22–P0.26 and P0.10–P0.12). Each channel has its own result register to eliminate interrupt service routine overhead during burst conversions.
Is the LPC2101FBD48,151 pin-compatible with other members of the LPC2100 family?
Yes, the LPC2101FBD48,151 shares identical LQFP48 pinout and electrical characteristics with LPC2102FBD48 and LPC2103FBD48. All three devices use the SOT313-2 package, same voltage rails (VDD(3V3), VDDA, VSSA, VDD(1V8)), and fully compatible peripheral register maps - enabling drop-in memory upgrades without layout changes.
What power-saving modes are available on the LPC2101FBD48,151?
The LPC2101FBD48,151 offers Idle mode, Power-down mode (with RTC active), and Deep power-down mode (Revision A+). In Deep power-down, SRAM and RTC can be retained using VBAT, achieving sub-1 µA current draw. Wake-up is supported via external interrupts (EINT0–EINT2) or RTC alarm, making it ideal for battery-powered remote sensors.
