Product details
Overview
LPC11U36FBD48/401 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller in LQFP48 package, operating up to 50 MHz with 96 kB flash, 10 kB SRAM (8 kB + 2 kB USB RAM), 4 kB EEPROM, full-speed USB 2.0 device controller, and USART supporting RS-485/smart card modes - deployed in USB audio devices and handheld scanners requiring integrated connectivity and low-power operation.
For engineers reviewing the LPC11U36FBD48/401 datasheet, LPC11U36FBD48/401 pinout, LPC11U36FBD48/401 application, or LPC11U36FBD48/401 equivalent, key selection criteria include USB device stack support in ROM, 4 kB byte-erasable EEPROM, 10-bit 8-channel ADC, I²C Fast-mode Plus (1 Mbit/s), and 40 GPIO pins with configurable pull-up/pull-down and interrupt capability.
Technical Context
The LPC11U36FBD48/401 integrates a dedicated USB PLL for stable 48 MHz USB clock generation independent of the main system PLL, enabling concurrent high-speed USB communication and CPU execution. Its memory subsystem includes separate 2 kB USB RAM block optimized for endpoint FIFO buffering and on-chip EEPROM with API-supported byte-level erase/program operations.
Peripheral routing is managed via IOCON registers per pin, supporting dynamic function assignment including dual-role pins like PIO0_17 (RTS/CT32B0_CAP0/SCLK) and PIO0_6 (USB_CONNECT/SCK0). The NVIC supports up to 32 interrupts with programmable priority, and the WWDT uses a dedicated low-power oscillator for reliable timeout detection during sleep modes.
