Product details
Overview
LPC2220FET144/G from NXP Semiconductors is a 16/32-bit ARM7TDMI-S microcontroller in TFBGA144 package, featuring 64 kB on-chip SRAM, 75 MHz CPU clock via programmable PLL, eight-channel 10-bit ADC (2.44 µs conversion), and dual 32-bit timers with PWM, RTC, and watchdog - deployed in industrial control, medical systems, and access control gateways.
For engineers reviewing the LPC2220FET144/G datasheet, LPC2220FET144/G pinout, LPC2220FET144/G application, or LPC2220FET144/G equivalent, key selection criteria include its 64 kB RAM capacity, TFBGA144 footprint compatibility, 5 V-tolerant GPIO count (up to 76 pins), fast GPIO toggle performance (3.5× baseline), and dual UARTs with hardware flow control and fractional baud rate generation.
Technical Context
The LPC2220FET144/G implements an ARM7TDMI-S core with Thumb instruction set support for 30 % code size reduction without significant performance loss. Its memory subsystem includes a configurable external bus interface supporting four banks (up to 16 MB each, 8/16/32-bit data width) and dedicated ADC result registers to reduce interrupt overhead.
Real-time debug capability is enabled via EmbeddedICE-RT and Embedded Trace interfaces, while peripheral integration includes Fast I²C (400 kbit/s), two SPIs (one replaceable by SSP), two UARTs with auto-bauding, and vectored interrupt controller (VIC) with configurable priorities and vector addresses.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM7-based microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC2210FBD144 | 16 kB SRAM, LQFP144 package, no fast GPIO or SSP; max 60 MHz clock. | Limited memory headroom for RTOS or large protocol stacks; lacks TFBGA space savings and thermal performance. | Select only for cost-sensitive, low-complexity designs where 16 kB RAM suffices and PCB layout favors LQFP. |
| LPC2220FBD144 | Identical electrical specs and feature set, but LQFP144 package instead of TFBGA144. | No change in functionality; differs only in mechanical footprint, thermal resistance, and board assembly process. | Choose when TFBGA reflow capability is unavailable or when legacy LQFP tooling must be retained. |
Compared with LPC2210FBD144, the LPC2220FET144/G offers 4× more RAM and higher clock speed for demanding firmware; versus LPC2220FBD144, it delivers superior thermal dissipation and smaller PCB area in space-constrained embedded gateways.

FAQ
What is the maximum operating frequency of the LPC2220FET144/G?
The LPC2220FET144/G achieves a maximum CPU clock of 75 MHz using its on-chip programmable Phase-Locked Loop (PLL), which has a 100 µs settling time. This frequency is confirmed in the official NXP LPC2210/2220 datasheet Rev. 06 and applies specifically to the LPC2220FET144/G variant, distinguishing it from the 60 MHz LPC2210.
Does the LPC2220FET144/G include on-chip flash memory?
No, the LPC2220FET144/G is a flashless microcontroller. It contains 64 kB of on-chip static RAM but relies on external memory (e.g., NOR flash via its configurable external bus interface) for program storage. This architecture allows flexible firmware updates and larger code footprints than on-chip flash-limited devices.
How many analog inputs does the LPC2220FET144/G support, and what is their voltage tolerance?
The LPC2220FET144/G supports eight 10-bit analog inputs (AIN0–AIN7), with conversion time as low as 2.44 µs. All ADC input pins are 5 V tolerant when configured for analog use, and the analog section is electrically isolated from the digital I/O domain to maintain accuracy.
What debug interfaces are supported by the LPC2220FET144/G?
The LPC2220FET144/G supports EmbeddedICE-RT and Embedded Trace interfaces for real-time debugging and instruction execution tracing. These interfaces use standard JTAG signals (TCK, TMS, TDI, TDO, TRST) plus trace-specific pins (TRACEPKT[3:0], TRACESYNC, TRACECLK) to enable non-intrusive firmware analysis without halting execution.
Is the LPC2220FET144/G pin-compatible with other LPC22xx variants?
The LPC2220FET144/G shares identical electrical functionality and pin definitions with the LPC2220FBD144, but uses a TFBGA144 package instead of LQFP144 - meaning ball-to-land mapping matches functionally but not mechanically. It is not pin-compatible with LPC2210 variants due to differences in RAM size, fast GPIO implementation, and SSP availability.
