For engineers reviewing the LPC2106FBD48/01 datasheet, LPC2106FBD48/01 pinout, LPC2106FBD48/01 application, or LPC2106FBD48/01 equivalent, key selection criteria include its −40 °C to +85 °C industrial temperature range, 5 V tolerant I/Os, Fast GPIO capability, on-chip trace support, and ISP/IAP flash programming via bootloader.
Technical Context
The LPC2106FBD48/01 implements an ARM7TDMI-S core with Thumb instruction set for code density optimization, coupled with a 128-bit wide memory interface enabling full 32-bit execution at 60 MHz. Its Vectored Interrupt Controller supports configurable priorities across 16 vectored IRQ channels and FIQ/IRQ classification.
It integrates two 32-bit timers (7 capture/compare channels), a 6-channel PWM unit, Real-Time Clock, Watchdog, Fast I²C-bus (400 kbit/s), SPI/SSP controller, and dual UARTs with hardware handshake flow control-enabling real-time deterministic response in embedded control loops and serial protocol bridging.

|---|---|---|---|
| LPC2106FBD48 | No /01 suffix; same flash (128 kB), RAM (64 kB), package (LQFP48), and temperature range (−40 °C to +85 °C). | Identical functional capability; /01 variant includes minor silicon revisions improving trace signal integrity and JTAG reliability. | Select LPC2106FBD48/01 when trace debugging or production programming stability is critical; otherwise LPC2106FBD48 is functionally interchangeable. |

FAQ
What is the maximum operating frequency of the LPC2106FBD48/01?
The LPC2106FBD48/01 supports a maximum CPU clock frequency of 60 MHz, achieved via its on-chip programmable Phase-Locked Loop (PLL) with 100 µs settling time. This frequency is validated across the full −40 °C to +85 °C industrial temperature range and requires proper decoupling of both VDD(1V8) and VDD(3V3) supplies per NXP's layout guidelines.
Does the LPC2106FBD48/01 support in-system programming (ISP)?
Yes, the LPC2106FBD48/01 supports In-System Programming via its built-in bootloader, enabling flash updates over UART0 without requiring a dedicated programmer. The bootloader occupies the first 8 kB of flash, leaving 120 kB available for user code; programming speed is 1 ms per 512-byte line, and sector erasure takes 400 ms.
How many UART interfaces does the LPC2106FBD48/01 include, and what advanced features do they offer?
The LPC2106FBD48/01 includes two UART interfaces (UART0 and UART1). Both support fractional baud rate generation, autobaud detection, and hardware handshake flow control (CTS/RTS/DSR/DTR/DCD/RI). UART1 additionally supports modem status interrupts and end-of-autobaud signaling-critical for reliable soft modem and legacy serial device integration.
What is the purpose of the /01 suffix in LPC2106FBD48/01?
The /01 suffix in LPC2106FBD48/01 denotes a specific silicon revision that improves trace signal integrity and JTAG interface reliability compared to earlier versions like LPC2106FBD48/00. It retains identical electrical specifications, memory configuration (128 kB flash, 64 kB SRAM), package, and temperature range-but adds enhanced robustness for production programming and real-time trace debugging.
Can the LPC2106FBD48/01 operate with a 5 V external peripheral interface?
Yes, the LPC2106FBD48/01 features 32 GPIO pins rated for 5 V tolerance with TTL input thresholds and hysteresis, allowing direct connection to 5 V logic peripherals without level shifters. However, its I/O power supply (VDD(3V3)) must remain within 3.0–3.6 V, and all 5 V signals must be applied only to designated GPIO pins-not to VDD(3V3) or other power rails.
