FAQ
What is the operating temperature range for the LPC2106FHN48/01?
The LPC2106FHN48/01 is rated for industrial operation from −40 °C to +85 °C. This range is confirmed in Table 2 of the official NXP datasheet and applies specifically to all /01-suffixed variants including LPC2106FHN48/01. The device maintains full specification compliance - including 60 MHz CPU operation, flash programming, and peripheral functionality - across this entire range.
Does the LPC2106FHN48/01 support in-system programming (ISP)?
Yes, the LPC2106FHN48/01 supports In-System Programming via its UART0 interface using the on-chip bootloader. Flash programming takes 1 ms per 512-byte line, and sector or full-chip erase completes in 400 ms. This capability is inherent to the LPC2106 part number and is fully functional in the LPC2106FHN48/01 variant, enabling field firmware updates without removing the device from the PCB.
How many UART interfaces does the LPC2106FHN48/01 include, and what advanced features do they offer?
The LPC2106FHN48/01 includes two UART interfaces (UART0 and UART1). Both support fractional baud rate generation, hardware auto-bauding, and full handshake flow control (RTS/CTS/DSR/DTR/DCD/RI) implemented entirely in hardware - eliminating CPU polling overhead. These features are explicitly documented for LPC2104/2105/2106/01 devices and apply directly to the LPC2106FHN48/01.
What debug and trace capabilities are integrated into the LPC2106FHN48/01?
The LPC2106FHN48/01 integrates EmbeddedICE-RT for real-time breakpoint and watchpoint debugging, plus an Embedded Trace Macrocell (ETM) supporting non-intrusive instruction trace. Trace signals include TRACECLK, TRACESYNC, and four TRACEPKT lines - all accessible on dedicated HVQFN48 pins (P0.22, P0.26, P0.27–P0.30). This trace capability is confirmed for LPC2106/01 devices and functions identically in the LPC2106FHN48/01 package.
Is the LPC2106FHN48/01 pin-compatible with other LPC2106 variants such as LPC2106FBD48/01?
No - the LPC2106FHN48/01 uses an HVQFN48 package (SOT619-1), while LPC2106FBD48/01 uses LQFP48 (SOT313-2). Although both have 48 terminals and identical pin functions, their physical layouts differ: HVQFN48 has perimeter pads with no leads, whereas LQFP48 has gull-wing leads. PCB layout, soldering profile, and thermal design must be adapted accordingly; they are not drop-in replacements.
