It integrates a USB full-speed device controller alongside I²C, SPI, SSP, UART/USART, and Microwire serial interfaces, plus an 8-channel 10-bit ADC. The part is rated for the industrial temperature range of -40°C to 85°C and operates from a 2 V to 3.6 V supply. It comes in a 48-LQFP (7×7 mm) surface-mount package with 42 general-purpose I/O lines. ## 72 MHz Cortex-M3 — throughput for USB and control loops The 72 MHz core clock on this Cortex-M3 delivers enough headroom for single-cycle multiply and bit-banding operations typical in USB polling loops and sensor-fusion algorithms. The 16 KB Flash and 4 KB RAM limit firmware to compact, single-purpose applications — think USB-to-serial bridges, keypad controllers, or simple data loggers — not multitasking RTOS stacks. The 42 I/O lines include USB D+/D−, multiple serial ports, and ADC inputs.","metaTitle":"NXP LPC1342FBD48151 ARM Cortex-M3 MCU, 72 MHz, 16 KB Flash, 48-LQFP","metaDescription":"NXP LPC1342FBD48151 32-bit ARM Cortex-M3 MCU, 72 MHz, 16 KB Flash, 4 KB RAM, USB full-speed, 42 I/O, 8×10-bit ADC, -40°C to 85°C, 48-LQFP.
