NXP Semiconductors LPC2210FBD144,551

Overview

LPC2210FBD144,551 from NXP Semiconductors is a 16/32-bit ARM7TDMI-S microcontroller in LQFP144 package, delivering 60 MHz CPU clock, 16 kB on-chip SRAM, eight-channel 10-bit ADC (2.44 µs conversion), and dual 32-bit timers with PWM and capture/compare functions. It serves as the central control unit in industrial PLCs, medical sensor interfaces, and access control panels requiring deterministic real-time response and mixed-signal I/O.

For engineers reviewing the LPC2210FBD144,551 datasheet, LPC2210FBD144,551 pinout, LPC2210FBD144,551 application, or LPC2210FBD144,551 equivalent, key selection criteria include its 144-pin LQFP footprint, 5 V-tolerant GPIO (up to 76 pins), external memory interface supporting four banks up to 16 MB each, and integrated debug via EmbeddedICE-RT and trace support.

Technical Context

The LPC2210FBD144,551 implements the ARM7TDMI-S core with Thumb instruction set for code density optimization-reducing firmware size by >30% with minimal performance penalty. Its memory subsystem includes a configurable external bus controller supporting 8/16/32-bit data width across four independent banks, enabling direct connection to NOR flash, SRAM, or peripheral ASICs.

Real-time capability is reinforced by a Vectored Interrupt Controller (VIC) with programmable priorities and vector addresses, two 32-bit timers (each with four capture and four compare channels), and hardware handshake flow control on UART0/UART1. The device lacks on-chip flash but supports in-system programming via UART0 serial bootloader.

FAQ

What is the maximum operating frequency of the LPC2210FBD144,551?

The LPC2210FBD144,551 operates at a maximum CPU clock frequency of 60 MHz, generated by its on-chip Phase-Locked Loop (PLL) with 100 µs settling time. This frequency is fixed for this variant-unlike the LPC2210/01 and LPC2220, which support 75 MHz. The 60 MHz clock enables deterministic real-time execution with 16.7 ns instruction cycle timing, suitable for industrial control loops and sensor sampling.

Does the LPC2210FBD144,551 include on-chip flash memory?

No, the LPC2210FBD144,551 does not include on-chip flash memory. It is a flashless microcontroller relying on external memory (via its configurable 4-bank interface) or in-system programming through the UART0 serial bootloader. This architecture reduces die cost and allows flexible firmware storage options-including parallel NOR flash or external SPI flash with appropriate interface logic-while retaining full ARM7TDMI-S functionality.

How many analog inputs does the LPC2210FBD144,551 support?

The LPC2210FBD144,551 supports eight analog input channels (AIN0–AIN7) as part of its 10-bit successive approximation ADC. These inputs are mapped to specific GPIO pins (e.g., P0.27–P0.30, P2.30–P2.31, P3.28–P3.29), all 5 V tolerant when configured for analog mode. The ADC achieves 2.44 µs conversion time, enabling aggregate sampling rates exceeding 400 ksps across multiple channels for real-time sensor monitoring.

Is the LPC2210FBD144,551 pin-compatible with the LPC2210FBD144/01?

Yes, the LPC2210FBD144,551 is pin-compatible with the LPC2210FBD144/01-both use the identical LQFP144 (SOT486-1) package with matching pinout and electrical characteristics. However, functional differences exist: the /01 variant adds Fast GPIO, SSP interface, and enhanced UART features (fractional baud, auto-baud), while the LPC2210FBD144,551 omits these to reduce cost and complexity in applications where they are unnecessary.

What debug interfaces are supported by the LPC2210FBD144,551?

The LPC2210FBD144,551 supports JTAG-based debugging via EmbeddedICE-RT and an Embedded Trace Macrocell (ETM), enabling real-time instruction tracing and non-intrusive breakpoints using standard ARM debug tools. Pins TDI, TDO, TCK, TMS, and TRST are dedicated to JTAG, while P1.20–P1.24 provide trace clock and packet signals. This infrastructure allows full visibility into program flow and timing behavior during development and validation of safety-critical firmware.
