Product details
Overview
LPC11A14FBD48/301 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller in LQFP48 package, operating at up to 50 MHz with 32 kB flash, 8 kB SRAM, and 4 kB EEPROM. It integrates a 10-bit ADC (8 channels), 10-bit DAC, analog comparator, temperature sensor, and dual SSP controllers - used in industrial control, remote monitoring, and precision instrumentation where mixed-signal integration and low-power operation are critical.
For engineers reviewing the LPC11A14FBD48/301 datasheet, LPC11A14FBD48/301 pinout, LPC11A14FBD48/301 application, or LPC11A14FBD48/301 equivalent, key selection factors include its 42 GPIO count, I²C Fast-mode Plus (1 Mbit/s), RS-485 USART support, configurable glitch filters (10 ns/50 ns), and SWD debug interface - all validated for LQFP48 layout compatibility and industrial temperature range (−40 °C to +85 °C).
Technical Context
The LPC11A14FBD48/301 implements an ARM Cortex-M0 core with NVIC and system tick timer, paired with a flexible clock system including 1–25 MHz crystal oscillator, 12 MHz ±1% IRC, and programmable PLL for CPU frequency scaling. Its memory subsystem includes boot ROM (16 kB), ISP/IAP capability, and byte-erasable EEPROM.
Analog/mixed-signal configuration is software-driven: the 10-bit ADC supports 8-channel multiplexing with trigger inputs ATRG0/ATRG1; the 10-bit DAC features flexible conversion triggering; and the analog comparator offers programmable reference voltage and multiple input options (ACMP_I1–I5) with dedicated output (ACMP_O).
