Board User Manual
The FRDM-MCXE31B board is a design and evaluation platform based on the NXP MCX E31B microcontroller (MCU). The MCX E31B MCU is based on an Arm Cortex-M7 core, running at speeds of up to 160 MHz with a 2.95 V–5.5 V supply.
The FRDM-MCXE31B board includes:
- One MCX E31B device
- 64 Mbit external serial flash (Winbond)
- FXLS8974CFR3 I2C accelerometer sensor
- NMH1000 I2C magnetic switch
- Three TJA1057BTK CAN PHYs
- Ethernet PHY
- RGB LED
- Push buttons
- MCU-Link debug probe circuit
The board is compatible with Arduino shield modules, Pmod boards, and mikroBUS.
For debugging, the board uses an onboard (OB) debug probe, MCU-Link OB, based on the NXP LPC55S16 MCU.
In this document, the MCX E31B is referred to as the target MCU, and the LPC55S16 as the debug MCU.
This document provides detailed information about the FRDM-MCXE31B board interfaces, accelerometer, power supplies, clocks, connectors, jumpers, push buttons, LEDs, and the MCU-Link OB debug probe.
