Product details
Overview
LPC2220FET144/G from NXP Semiconductors is a 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), dual 32-bit timers with PWM and capture, and dual UARTs with fractional baud rate generation - deployed in industrial control and medical systems requiring deterministic real-time I/O.
For engineers reviewing the LPC2220FET144/G datasheet, LPC2220FET144/G pinout, LPC2220FET144/G application, or LPC2220FET144/G equivalent, key selection criteria include 5 V-tolerant GPIO count (up to 76 pins), external memory interface (4 banks, up to 16 MB each), Fast GPIO capability, and integrated trace/debug support for embedded firmware development.
Technical Context
The LPC2220FET144/G implements ARM7TDMI-S core with Thumb instruction set for 30 % code size reduction versus ARM mode, while maintaining near-native performance. Its memory subsystem includes configurable external bus interface supporting 8/16/32-bit data width across four independent banks.
Real-time peripherals include two 32-bit timers (each with four capture/compare channels), RTC, watchdog, and an 8-channel 10-bit ADC with dedicated result registers to minimize interrupt latency. Serial connectivity comprises two UARTs (16C550-compatible), Fast I²C (400 kbit/s), two SPIs, and one SSP - all accessible via multiplexed GPIO pins managed by Pin Connect Block.

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 Phase-Locked Loop (PLL). This frequency is programmable with a 100 µs settling time and supported across the full industrial temperature range (−40 °C to +85 °C). The LPC2220FET144/G maintains this performance while delivering deterministic interrupt response and real-time peripheral timing.
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 no internal flash memory. Firmware must be loaded externally via the serial bootloader (using UART0) or executed from external memory mapped into the 4-bank external memory interface. This architecture allows flexible code storage options including NOR flash or EEPROM.
How many analog inputs does the LPC2220FET144/G support?
The LPC2220FET144/G integrates an 8-channel 10-bit successive approximation ADC. Analog inputs AIN0 through AIN7 are assigned to specific GPIO pins (e.g., P0.27, P0.28, P2.30, P2.31, P3.28, P3.29), all 5 V tolerant when configured for analog use. Each channel supports conversion times as low as 2.44 µs, and dedicated result registers reduce interrupt servicing overhead.
Is the LPC2220FET144/G pin-compatible with the LPC2210 series?
The LPC2220FET144/G shares identical pin functions and ball allocation with the LPC2210/01 family in TFBGA144 packaging, but differs in memory size (64 kB vs. 16 kB) and enabled features (Fast GPIO, SSP, enhanced UARTs). While electrical and mechanical pinout matches, firmware and PCB layout must account for functional differences - especially ADC result register usage and memory map configuration.
What debug interfaces are supported by the LPC2220FET144/G?
The LPC2220FET144/G supports JTAG (TRST/TCK/TMS/TDI/TDO) via dedicated pins and includes EmbeddedICE-RT for real-time debugging. It also provides full Embedded Trace Interface with dedicated trace port pins (TRACEPKT0–3, TRACESYNC, TRACECLK, TRACECLK) for non-intrusive instruction-level tracing - essential for optimizing timing-critical firmware and diagnosing race conditions in the LPC2220FET144/G.
