UART and SPI in the same chip?
« on: September 19, 2018, 01:23:12 PM »

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.

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,
