Product details
Overview
LPC2106FHN48 from NXP Semiconductors is a 32-bit ARM7TDMI-S microcontroller with 128 kB on-chip flash, 64 kB SRAM, 60 MHz max CPU clock, 32 GPIO pins (5 V tolerant), and dual UARTs with fractional baud rate generators - deployed in industrial control systems requiring compact footprint and low-power operation.
For engineers reviewing the LPC2106FHN48 datasheet, LPC2106FHN48 pinout, LPC2106FHN48 application, or LPC2106FHN48 equivalent, key selection criteria include HVQFN48 thermal performance, -40 °C to +85 °C operating range, 1.8 V core / 3.3 V I/O dual supply, embedded trace support, and Fast GPIO capability enabling 3.5× faster pin toggling than legacy variants.
Technical Context
The LPC2106FHN48 implements the ARM7TDMI-S RISC core with Thumb instruction set for 30 % code size reduction and near-32-bit performance. Its memory subsystem uses a 128-bit-wide interface and accelerator to sustain full 60 MHz execution speed from flash.
Peripheral integration includes two 32-bit timers (7 capture/compare channels), a 6-channel PWM unit, Real-Time Clock, Watchdog, Vectored Interrupt Controller (16 vectored IRQ slots), and dual UARTs with hardware handshake flow control - all accessible via multiplexed GPIO through the Pin Connect Block.
Key Specifications

|---|---|
| CPU Core | ARM7TDMI-S 32-bit RISC processor with Thumb mode support for optimized code density |
| Max Clock Speed | 60 MHz via on-chip PLL (100 µs settling time); enables real-time deterministic response |
| Flash Memory | 128 kB ISP/IAP flash with 100,000 erase/write cycles and 20-year data retention |
| SRAM | 64 kB on-chip static RAM accessible as 8/16/32-bit; supports fast interrupt handling and buffer-intensive protocols |
| GPIO | 32 × 5 V tolerant I/O pins in HVQFN48 package; Fast GPIO mode enables 3.5× higher toggle rate vs standard mode |
| Serial Interfaces | 2 × UART (16C550 compatible, fractional baud, autobaud, hardware flow control), I²C (400 kbit/s), SPI/SSP |
| Power Supply | Dual-rail: 1.65–1.95 V (1.8 V ±8.3 %) for core, 3.0–3.6 V (3.3 V ±10 %) for I/O with 5 V tolerant pads |

FAQ
What is the maximum operating temperature range for the LPC2106FHN48?
The LPC2106FHN48 is rated for industrial temperature operation from −40 °C to +85 °C. This range is confirmed in Table 2 of the official NXP datasheet and applies specifically to the /00 and /01 suffix variants - including the base LPC2106FHN48. The HVQFN48 package's thermal enhancement supports reliable operation at the upper limit under sustained 60 MHz operation.
Does the LPC2106FHN48 support in-application programming (IAP)?
Yes, the LPC2106FHN48 supports In-Application Programming (IAP) via its on-chip bootloader. It allows the running application to erase and reprogram flash memory sectors without halting execution - enabling field firmware updates and dynamic parameter storage. Flash programming takes 1 ms per 512 B line, and sector erase completes in 400 ms.
How many UART interfaces does the LPC2106FHN48 include, and what advanced features do they offer?
The LPC2106FHN48 includes two UART interfaces (UART0 and UART1). Both feature fractional baud rate generators, hardware handshake flow control (RTS/CTS), autobaud detection, and full 16C550 register compatibility. These capabilities enable robust communication with legacy modems, industrial sensors, and protocol converters across variable clock sources.
Is the LPC2106FHN48 pin-compatible with other members of the LPC210x family?
Yes - the LPC2106FHN48 shares identical pin configuration with all LPC2104/2105/2106 HVQFN48 variants (including /00 and /01 suffixes), as confirmed in Figure 3 and Section 5.1 of the datasheet. However, it is not pin-compatible with LQFP48 variants of other family members due to differing pin numbering conventions despite identical signal mapping.
What debug and trace capabilities are integrated into the LPC2106FHN48?
The LPC2106FHN48 integrates EmbeddedICE-RT for breakpoint/watchpoint debugging and an Embedded Trace Macrocell (ETM) for non-intrusive real-time instruction trace. It supports both primary and secondary JTAG pin groups (selected via DBGSEL), and includes dedicated trace signals (TRACECLK, TRACESYNC, TRACEPKT0–3) for high-fidelity firmware analysis without affecting runtime performance.
