FTDI Chip has introduced a series of easy-to-utilise modules to facilitate the evaluation, development and subsequent implementation of its 32-bit FT90X Super-Bridge microcontrollers (MCU). Optimised for use in home security, industrial control, home/building automation systems, data logging and embedded multimedia, the MM900EVxA module range comprises four different units.
The MM900EV2A and MM900EV3A incorporate 1,3 Mpixel camera modules, capable of capturing images from VGA (up to 30 fps) to SXGA (up to 15 fps) resolution in front-facing and rear-facing configurations respectively. Each module also has a built-in audio codec with microphone input pins, a 3,5 mm stereo headphone jack, a stereo speaker output header, DC power socket, 2 x RGB LEDs, reset switch and a real-time clock with coin cell battery support. An RJ45 connector allows 10/100 Mbps Ethernet data transfer and extra memory capacity can be made available via the Micro SD card socket.
The standard USB-A port (which provides the USB hosting) is complemented by a Micro-B USB port (which serves as a USB device port and a power source connection). A 40-way expansion connector enables access to the IC’s complete complement of I/O, while a Micro-MaTch 2x5 female socket facilitates the debugging/downloading process. An additional 2 x 8-pin, 2,54 mm pitch connector and 16-pin, 0,5 mm pitch FFC/FPC connector permit interfacing with FT800/FT810 EVE display modules.
Presenting engineers with more streamlined versions of the MM900EVxA platform are the MM900EV1A and MM900EV-LITE. The MM900EV1A offers exactly the same functionality as the MM900EV2A and MM900EV3A but excluding the camera unit, and is aimed primarily at bridging functions.
The MM900EV-LITE is optimised for HMI and embedded display applications. It dispenses with the need for Ethernet connectivity, audio codec and the USB Host, but instead has a supplementary I/O connector (so that these functions can be added on if required). This I/O connector provides connection to UART, PWM, ADC, DAC, SPI, I2C, CAN bus and camera interface.
All four modules are backed up by a comprehensive tool chain which allows engineers to get through the development phases without complications. The device firmware upgrade (DFU) interface on each module provides for direct loading of code without the need for any programming hardware.
The UMFTPD2A is designed to accompany FTDI Chip’s MM900EVxA and MM900EV-LITE modules. Through this, in addition to programming and firmware upload tasks, engineers can embark upon comprehensive debugging of their FT90X-based systems. It features an FT4232HL Hi-Speed USB 2.0 to multipurpose UART/MPSSE converter IC. As well as MPSSE and UART options, Bit-Bang connectivity is also included.
Based on the combination of proprietary processor topology and an ingenuous shadow RAM element, FT90X Super-Bridge MCU devices can differentiate themselves from conventional generic microcontrollers. They can achieve zero wait state operation at speeds of 100 MHz. This makes them highly suited to data intense applications, such as data bridging between a camera and an Ethernet connection or sensors and SD storage (for machine vision, building access and surveillance purposes).
