Product details
Overview
LPC43S30FET100K from NXP Semiconductors is a dual-core ARM Cortex-M4/M0 microcontroller for secure embedded control, operating at up to 204 MHz with 264 kB SRAM, integrated AES encryption engine, Ethernet MAC (RMII/MII), and dual high-speed USB interfaces (USB0 host/device/OTG + USB1 host/device). It targets industrial gateways requiring real-time processing, secure boot, and network connectivity.
For engineers reviewing the LPC43S30FET100K datasheet, LPC43S30FET100K pinout, LPC43S30FET100K application, or LPC43S30FET100K equivalent, key selection considerations include its TFBGA100 package (100-ball, 9 × 9 × 0.7 mm), absence of LCD controller, limited 4-channel ADC support, and USB1 interface restricted to full-speed PHY with no ULPI option - critical for USB peripheral integration planning.
Technical Context
The LPC43S30FET100K integrates an ARM Cortex-M4 core with hardware FPU and MPU alongside a companion Cortex-M0 coprocessor, enabling asymmetric task partitioning - e.g., M4 handles Ethernet/USB protocol stacks while M0 manages low-latency I/O or sensor preprocessing. Both cores share access to 264 kB SRAM across multiple banks, two of which support independent power-down.
Its clock system includes three PLLs: one for CPU operation up to 204 MHz, a dedicated USB PLL, and a configurable audio PLL. The device supports IEEE 1588-2008 v2 time stamping via its Ethernet MAC and features a ROM-based API for AES boot image decryption with DMA acceleration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC43S30FBD144 | LQFP144 package (20 × 20 mm); 83 GPIOs; retains LCD controller and full 8-channel ADC support | Better suited for HMI designs requiring local display driving and higher analog channel count | Select when board layout accommodates larger footprint and display interface is required - not pin-compatible with TFBGA100 |
| LPC43S20FET180 | TFBGA180 package (180-ball); reduced 200 kB SRAM; no Ethernet or LCD; USB1 disabled | Targeted at cost-sensitive, non-networked control applications with lower memory needs | Choose for simplified connectivity requirements where Ethernet and dual USB are unnecessary - different ball count and routing |
Compared with LPC43S30FET100K, the LPC43S30FBD144 offers expanded I/O and display capability at the cost of size, while the LPC43S20FET180 sacrifices networking and memory for lower BOM cost - neither is pin-compatible, requiring PCB redesign for migration.

FAQ
What is the maximum operating frequency of the LPC43S30FET100K?
The LPC43S30FET100K operates at a maximum CPU frequency of 204 MHz for both its ARM Cortex-M4 and Cortex-M0 cores. This frequency is achieved using the on-chip PLLs and is supported across the full industrial temperature range (-40°C to +85°C) with proper power supply regulation and thermal management.
Does the LPC43S30FET100K include on-chip flash memory?
No, the LPC43S30FET100K is a flashless microcontroller. It relies entirely on external memory or on-chip SRAM for program execution. It includes 264 kB of SRAM and 64 kB of ROM containing boot code and peripheral drivers, but no internal flash storage for user firmware.
How many ADC channels does the LPC43S30FET100K support?
The LPC43S30FET100K integrates two 10-bit ADCs (ADC0 and ADC1) with a combined total of 8 input channels. As confirmed in Table 2 of the datasheet, this applies specifically to the TFBGA100 variant - unlike higher-pin-count packages, it does not support more than 4 channels per ADC.
Is the LCD controller available on the LPC43S30FET100K?
No, the LCD controller is not available on the LPC43S30FET100K. According to Table 2 in the NXP datasheet Rev. 1.3, the "LCD" column shows "no" for all TFBGA100 variants, including LPC43S30FET100K. This omission reduces die size and power consumption for applications that do not require local display driving.
What USB interfaces are implemented on the LPC43S30FET100K?
The LPC43S30FET100K implements USB0 as a high-speed host/device/OTG interface with an on-chip high-speed PHY, and USB1 as a full-speed host/device interface with an on-chip full-speed PHY - no ULPI interface is available on USB1 for external high-speed PHY attachment.
