Product details
Overview
LPC11E36FHN33/501 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller in HVQFN33 package, operating up to 50 MHz with 96 kB flash, 12 kB SRAM, 4 kB EEPROM, 10-bit ADC (8 channels), and 28 GPIO pins. It integrates one USART with RS-485/smart card support, two SSP interfaces, one Fast-mode Plus I²C-bus (1 Mbit/s), four timers, and power management for industrial control and handheld scanners.
For engineers reviewing the LPC11E36FHN33/501 datasheet, LPC11E36FHN33/501 pinout, LPC11E36FHN33/501 application, or LPC11E36FHN33/501 equivalent, key selection criteria include its HVQFN33 thermal-enhanced footprint, 28 GPIO count, 96 kB flash/12 kB SRAM memory partitioning, I²C Fast-mode Plus compliance, and support for Deep power-down wake-up via dedicated WAKEUP pin.
Technical Context
The LPC11E36FHN33/501 implements an ARM Cortex-M0 core with NVIC and system tick timer, paired with a programmable PLL for CPU clock generation from either internal 12 MHz IRC or external 1–25 MHz crystal oscillator. Its peripheral bus architecture uses AHB-Lite to APB bridges for low-latency access to UART, SSP, I²C, and timer peripherals.
Power management includes four reduced-power modes (Sleep, Deep-sleep, Power-down, Deep power-down) controlled by an integrated PMU, with wake-up sources including reset, selectable GPIO, watchdog interrupt, and a dedicated WAKEUP pin - critical for battery-powered portable instrumentation and medical sensors.

FAQ
What is the maximum operating frequency of the LPC11E36FHN33/501?
The LPC11E36FHN33/501 operates at a maximum CPU frequency of 50 MHz, achieved using its integrated PLL with either the internal 12 MHz IRC oscillator or an external 1–25 MHz crystal. This frequency is fully supported across the specified industrial temperature range (−40 °C to +85 °C) and 1.8–3.6 V supply voltage.
Does the LPC11E36FHN33/501 include on-chip EEPROM, and what are its key characteristics?
Yes, the LPC11E36FHN33/501 includes 4 kB of on-chip EEPROM that is byte-erasable and byte-programmable, with API support in boot ROM. This eliminates the need for external non-volatile memory in applications requiring infrequent parameter storage, such as calibration data or device configuration, while maintaining data integrity across power cycles.
How many GPIO pins does the LPC11E36FHN33/501 provide, and what advanced I/O features are supported?
The LPC11E36FHN33/501 provides 28 general-purpose I/O pins in its HVQFN33 package. Each pin supports configurable pull-up/pull-down resistors, repeater mode, and true open-drain operation. Eight pins can serve as edge- or level-sensitive interrupt sources, and two GPIO grouped interrupt modules allow pattern-matching logic for complex wake-up conditions.
Can the LPC11E36FHN33/501 enter ultra-low-power states, and how is wake-up managed?
Yes, the LPC11E36FHN33/501 supports four reduced-power modes, including Deep power-down. Wake-up from Deep power-down is enabled exclusively via the dedicated WAKEUP pin (PIO0_16), which responds to a 50 ns LOW-going pulse. External pull-up is required on this pin for reliable operation - a design requirement confirmed in the official NXP datasheet Rev. 2.3.
What serial communication interfaces are integrated into the LPC11E36FHN33/501?
The LPC11E36FHN33/501 integrates one USART (with RS-485/EIA-485, synchronous mode, and ISO 7816 smart card support), two SSP controllers (SPI/SSI compatible), and one I²C-bus interface compliant with Fast-mode Plus (1 Mbit/s). These interfaces share GPIO pins and are fully configurable via IOCON registers for flexible system integration.
