Product details
Overview
LPC4333FET256 from NXP Semiconductors is a dual-core ARM Cortex-M4F/M0 microcontroller with 512 kB flash (256 kB per bank), 136 kB SRAM, Ethernet MAC, two high-speed USB interfaces (one OTG-capable), and a motor control PWM subsystem - deployed in industrial motor drives and power management systems requiring deterministic real-time processing.
For engineers reviewing the LPC4333FET256 datasheet, LPC4333FET256 pinout, LPC4333FET256 application, or LPC4333FET256 equivalent, key selection criteria include dual-core task partitioning (M4 for signal processing, M0 for peripheral offload), LBGA256 package compatibility with EMC and thermal constraints, IEEE 1588 time-stamping support for synchronized automation networks, and 164 GPIOs with GIMA crossbar routing for flexible I/O mapping.
Technical Context
The LPC4333FET256 integrates an ARM Cortex-M4F core (r0p1) running up to 204 MHz with hardware FPU, MPU, and NVIC, alongside a companion Cortex-M0 coprocessor (r0p0) operating at the same frequency for autonomous peripheral handling. Its memory subsystem includes dual-bank flash with accelerator, 16 kB EEPROM, and multiple SRAM blocks with independent power-down capability.
Peripherals are organized across AHB multilayer matrix and APB bridges: the State Configurable Timer (SCTimer/PWM) enables complex waveform generation; Global Input Multiplexer Array (GIMA) routes signals between timers, ADCs, and SCT; and dual USB controllers feature on-chip PHYs (HS USB0 with integrated HS PHY, HS USB1 with ULPI interface).

FAQ
What is the maximum operating frequency of the LPC4333FET256?
The LPC4333FET256 features two ARM cores: the Cortex-M4F operates at up to 204 MHz with hardware floating-point unit, and the Cortex-M0 coprocessor also runs at up to 204 MHz. Both cores derive clock from independent PLLs, allowing simultaneous full-speed operation without contention. This dual-frequency capability is confirmed in Section 2.1 of the NXP LPC435X_3X_2X_1X datasheet Rev. 5.4.
Does the LPC4333FET256 support IEEE 1588 Precision Time Protocol?
Yes, the LPC4333FET256 Ethernet MAC includes full IEEE 1588-2008 v2 hardware timestamping support, enabling sub-microsecond synchronization accuracy for industrial automation networks. The timestamp engine captures transmit/receive packet timestamps in hardware, and the RTC alarm timer can trigger time-critical actions - both capabilities are documented in the Ethernet chapter of the LPC435X_3X_2X_1X datasheet.
How many GPIO pins does the LPC4333FET256 provide in the LBGA256 package?
The LPC4333FET256 in LBGA256 package provides 164 GPIO pins, mapped across ports P0–P9 and PA–PF. Each pin supports up to eight configurable functions via the System Configuration Unit (SCU), including GPIO, peripheral signals (e.g., ENET, USB, ADC), and event inputs for the SCTimer or GIMA. This count is explicitly listed in Table 2 of the datasheet under "GPIO" column for LPC4333FET256.
What is the flash memory configuration of the LPC4333FET256?
The LPC4333FET256 contains 512 kB of on-chip flash memory, organized as two independent 256 kB banks (Bank A and Bank B). This dual-bank structure enables background programming and live firmware updates without halting execution - a key feature for fail-safe industrial applications. The configuration is verified in Table 2 ("Ordering options") of the NXP datasheet Rev. 5.4.
Is the LPC4333FET256 pin-compatible with other LPC43xx variants in LBGA256?
Yes, all LPC43xx parts in LBGA256 package - including LPC4333FET256, LPC4337FET256, LPC4353FET256, and LPC4357FET256 - share identical pinout and ball assignment per NXP's SOT740-2 mechanical specification. Functional differences (e.g., LCD presence, PWM availability) are implemented via internal mask options, not pin remapping - confirmed in Section 6.1 ("Pinning") and Table 2 of the datasheet.
