  Ultimate Bridging Solutions with New 8-Bit and 32-Bit MCUs

As part of FTDI Chip's continuing ethos of 'Design Made Easy'  two new microcontrollers (MCUs) have now been introduced, which have been developed with key functionality to enhance system performance and operational efficiency.

Based upon FTDI Chip's new FT32, high performance 32-bit RISC core, the FT90x series provides a plethora of connectivity options, making it the ideal choice for advanced technology bridging solutions. By executing instructions from shadow RAM, rather than flash memory, the FT90x can operate at true Zero Wait States (0WS) up to 100MHz and 310 DMIPS performance. Using the industry standard GCC compiler, together with the Eclipse IDE, allows the FT90x to utilise a wide variety of third-party and open source software.

For price sensitive customers looking for a proven CPU architecture and a mature toolchain, the FT51A, based on an 8051-compatible core, gives 48MIPS processing power. The FT51A integrates a Low/Full speed USB hub and provides a downstream port, allowing multiple devices to be cascaded or combined with other USB devices. In addition to standard 8051 functions, the FT51A includes multiple ADCs facilitating analog measurement applications along with a fully configurable USB Device Controller, analogous to the FTDI Chip FT12 series.
