UART and SPI in the same chip?
(1/1)
kahlenberg:
Hi,
Is there any FTDI chip that handles UART and SPI in one chip?
I need UART and SPI in my project and I don't want to employ two chips.
FTDI Community:
Hello,
Yes, please consider our FT2232H (2 channel) or FT4232H (4 channel) ICs.
So you could have one channel for UART and the other for SPI.
Note the SPI is a master only.
By default the channel is UART, so the other channel would need to be configured for SPI
See FTDI MPSSE Basics.
See our existing MPSSE Example projects:
https://www.ftdichip.com/Support/SoftwareExamples/MPSSE.htm
There are two options to use I2C/SPI modes with the MPSSE engine:
a. Use LibMPSSE libraries. Example code is provided with the download. Please note that there is a beta version of LibMPSSE: libMPSSE__0_6_Beta.zip.
b. Use D2XX drivers direct. Example code is shown at SPI. AN_108 Command Processor For MPSSE and MCU Host Bus Emulation Modes provides the necessary information.
We have hardware available for test and evaluation:
FT2232H Mini-Module
FT2232H-56 Mini-Module
The FT2232H-56 Mini-Module is easier to power by just using a jumper. The other module requires some external connections.
Best Regards,
