NXP Semiconductors LPC2210FBD144/01,5

Overview

LPC2210FBD144/01 from NXP Semiconductors is a 16/32-bit ARM7TDMI-S microcontroller in LQFP144 package, operating at up to 75 MHz with 16 kB on-chip SRAM, eight-channel 10-bit ADC (2.44 µs conversion), and dual 32-bit timers with PWM outputs. It serves as a main system controller in industrial control panels requiring real-time interrupt response, analog sensor interfacing, and external memory expansion.

For engineers reviewing the LPC2210FBD144/01 datasheet, LPC2210FBD144/01 pinout, LPC2210FBD144/01 application, or LPC2210FBD144/01 equivalent, key selection criteria include its 75 MHz CPU clock, Fast GPIO capability (3.5× faster toggling), dedicated ADC result registers, fractional baud rate UARTs, and 5 V-tolerant I/O pins supporting mixed-voltage system integration.

Technical Context

The LPC2210FBD144/01 implements the ARM7TDMI-S core with Thumb instruction set support for code density optimization, enabling up to 30 % smaller firmware footprint without significant performance loss. Its memory subsystem includes a configurable external bus interface supporting four banks (up to 16 MB each) with 8/16/32-bit data width and byte-lane select signals (BLS0–BLS3).

Real-time debug is enabled via EmbeddedICE-RT and embedded trace interfaces, while peripheral control uses a Vectored Interrupt Controller (VIC) with programmable priorities and vector addresses. The device integrates two UARTs with hardware handshake, Fast I²C (400 kbit/s), two SPIs (one replaceable by SSP), RTC, watchdog, and a 6-channel PWM unit with capture/compare functionality.

FAQ

What is the maximum operating frequency of the LPC2210FBD144/01?

The LPC2210FBD144/01 operates at a maximum CPU clock frequency of 75 MHz, achieved via its programmable on-chip Phase-Locked Loop (PLL) with 100 µs settling time. This frequency applies specifically to the /01 variant; standard LPC2210 is limited to 60 MHz. The PLL accepts input clocks from 1 MHz to 25 MHz crystals or oscillators.

Does the LPC2210FBD144/01 support in-system programming?

Yes, the LPC2210FBD144/01 supports in-system programming via its UART0 serial bootloader. This allows firmware updates without removing the device from the PCB. The bootloader activates automatically on reset when specific pin states (e.g., P0.14 low during RESET) are detected, enabling field upgrades and manufacturing programming.

How many ADC channels does the LPC2210FBD144/01 have, and what is their resolution?

The LPC2210FBD144/01 integrates an eight-channel 10-bit successive approximation register (SAR) ADC with a minimum conversion time of 2.44 µs. Channels AIN0–AIN7 are mapped to dedicated pins including P0.27–P0.30, P2.30–P2.31, and P3.28–P3.29. Each channel supports independent sampling and features dedicated result registers to minimize interrupt latency.

Is the LPC2210FBD144/01 pin-compatible with other LPC22xx devices?

Yes, the LPC2210FBD144/01 is pin-compatible with LPC2210FBD144 and LPC2220FBD144 in the LQFP144 package (SOT486-1). All share identical pinouts, power domains, and peripheral mappings. Functional differences-such as 75 MHz clock, Fast GPIO, and dedicated ADC registers-are enabled by internal configuration and do not affect physical layout or PCB design.

What debug interfaces are supported by the LPC2210FBD144/01?

The LPC2210FBD144/01 supports JTAG-based debugging via TRST, TCK, TMS, TDO, and TDI pins (P1.31, P1.29, P1.30, P1.27, P1.28), plus EmbeddedICE-RT and embedded trace modules. These enable real-time instruction tracing, non-intrusive breakpoints, and on-chip RealMonitor software integration-critical for validating real-time behavior in industrial control firmware.
