NXP Semiconductors LPC4333JBD144E

Overview

LPC4333JBD144E from NXP Semiconductors is a dual-core ARM Cortex-M4F/M0 microcontroller with 512 kB flash (256 kB per bank), 136 kB SRAM, 16 kB EEPROM, and integrated peripherals including dual high-speed USB 2.0 interfaces (one OTG-capable), 10/100T Ethernet MAC with IEEE 1588 support, two 10-bit ADCs (400 kS/s), one 10-bit DAC, and an External Memory Controller - deployed in industrial motor control and embedded audio systems.

For engineers reviewing the LPC4333JBD144E datasheet, LPC4333JBD144E pinout, LPC4333JBD144E application, or LPC4333JBD144E equivalent, key selection considerations include its LQFP144 package with 83 GPIOs, absence of LCD controller and motor control PWM, J-grade temperature range (−40 °C to +105 °C), and dual-core real-time partitioning capability between Cortex-M4F and Cortex-M0.

Technical Context

The LPC4333JBD144E implements a tightly coupled dual-processor architecture: the ARM Cortex-M4F core runs at up to 204 MHz with hardware FPU, MPU, and ETM/ETB trace support, while the companion Cortex-M0 co-processor operates at up to 204 MHz for peripheral offload and deterministic control tasks. Both cores share access to AHB-based memory and peripherals via a multilayer matrix interconnect.

Peripherals are routed through the Global Input Multiplexer Array (GIMA) and State Configurable Timer (SCTimer/PWM), enabling event-driven cross-triggering between timers, ADCs, and GPIOs. The device supports execute-in-place (XIP) from Quad SPI Flash Interface (SPIFI) and features dual USB PHYs - one on-chip high-speed PHY (USB0), one ULPI interface (USB1) - with ROM-resident USB stack and electrical test software.

FAQ

What is the maximum operating frequency of the LPC4333JBD144E?

The LPC4333JBD144E supports a maximum CPU frequency of 204 MHz for both the ARM Cortex-M4F and Cortex-M0 cores. This performance level is achieved using internal PLLs fed from either the 1–25 MHz crystal oscillator or the 12 MHz internal RC oscillator (trimmed to ±3 % accuracy). The device maintains this speed across its full −40 °C to +105 °C industrial temperature range.

Does the LPC4333JBD144E include an LCD controller?

No, the LPC4333JBD144E does not include an LCD controller. According to the official NXP datasheet (Rev. 5.4), the LCD controller is available only on LPC4357/53 variants. The LPC4333JBD144E shares the same LQFP144 package and temperature grade but omits this peripheral - confirmed in Table 2 "Ordering options" where "LCD" is marked "no" for all LPC433x parts.

How many GPIO pins are available on the LPC4333JBD144E?

The LPC4333JBD144E provides 83 GPIO pins. This count is explicitly documented in Table 2 of the NXP datasheet under the "GPIO" column for the LPC4333JBD144 entry. These pins are distributed across ports P0–P9 and PA–PF, each configurable via the System Configuration Unit (SCU) for up to eight alternate functions including UART, I2C, SPI, and timer I/O.

What USB configurations does the LPC4333JBD144E support?

The LPC4333JBD144E supports two independent USB 2.0 controllers: USB0 includes a built-in high-speed PHY and operates in Host/Device/OTG mode with ROM-resident USB stack; USB1 uses an ULPI interface to connect to an external high-speed PHY and operates in Host/Device mode only. Both controllers support DMA and are fully compliant with USB 2.0 specifications.

Is the LPC4333JBD144E pin-compatible with other LPC43xx LQFP144 variants?

Yes, the LPC4333JBD144E is pin-compatible with other LPC43xx devices in the LQFP144 package (e.g., LPC4337JBD144, LPC4353JBD144), sharing identical mechanical dimensions, pin count, and pinout mapping per Figure 5 and Table 3 of the datasheet. Functional differences (e.g., flash size, LCD, PWM) do not affect physical compatibility - enabling drop-in replacement within the same package family.
