Flexcomm module

Voltage translator

Connector / MCU-Link target

Bidirectional voltage translator U22

(74AVC4TD245BQ). It supports a USB-to-UART

bridge between MCU-Link and the target MCU,

by shifting voltage levels of signals between

the two devices from 3.3 V to 3.3/1.9 V and

vice versa. The USB-to-UART bridge can be

disabled (so that the target MCU USART port

can be used for other purposes) by shorting

jumper JP26.

MCU-Link target (LPC55S69). The USB-to-

UART bridge between MCU-Link and the target

MCU can be used for debugging the target

MCU from MCU-Link.

Bidirectional voltage translator U11

(74AVC4TD245BQ). It creates an external

UART connection from USART connector JP3,

by shifting voltage levels of signals between

JP3 and the target MCU from 3.3 V to 3.3/1.9

V and vice versa. Before using this connection,

short jumper JP26 to disable the USB-to-UART

bridge between MCU-Link and the target MCU.

The UART connection is disabled by default. It

can be enabled by opening jumper JP12.

USART connecter JP3. It is a 1x3 pin header

with the following pinout:

•

Pin 1: FC0_RXD

•

Pin 2: FC0_TXD

•

Pin 3: Ground (GND)

JP3 supports an external UART connection

using a USB-to-serial cable. It operates at 3.3 V.
To prevent the board from powering up using

the USB-to-serial cable, power on the board

before connecting the USB-to-serial cable.

FC0

Motor 2 c Arduino socket connector

J122. It allows a UART connection between the

target MCU and board/module attached to the

socket, using its pin 2 (RXD) and pin 4 (TXD).

FC2

mikroBUS socket connector J8. It allows a

UART connection between the target MCU and

click board plugged into the mikroBUS socket,

using its pin 3 (RX) and pin 4 (TX).

Table 12. LPCXpresso55S36 USART connections

2.5 I2C interface

The target MCU has an I2C module, which can be accessed using its Flexcomm

modules 0-7. In the LPCXpresso55S36 board, the I2C module is accessed using

Flexcomm modules 1, 3, and 7 of the target MCU.
The figure below shows the I2C diagram of the LPCXpresso55S36 board.
