Maxim's collection of peripheral modules for FPGAs

-July 02, 2012

Dave Sackett, Manager of field applications told us that Maxim Integrated Products, Inc. is announcing a collection of 15 peripheral modules.

The collection includes functionality for data conversion, a digital potentiometer, real-time clock, light sensor, clock oscillator, thermal interface, communication transceivers, digital isolation, GPIO expansion, LED interface, and relay drivers. See Figure 1.

Maxim recognized that peripheral modules are becoming popular for circuit prototyping. This collection supports a wide variety of commonly used analog and mixed-signal functions. The modules are supported by example software and FPGA configuration files for three popular FPGA platforms. Straightforward example programs written in C demonstrate each module so the user is prototyping quickly for fast time to market.

Software drivers are partitioned and well documented. Designers can easily cut & paste drivers into their program.

Maxim’s Analog Essentials collection of peripheral modules complements Avnet’s  Spartan®-6 LX9 MicroBoard and upcoming ZedBoard, both of which incorporate several Pmod™-compatible expansion connectors. See Figure 4.

The good news regarding flexibility is that Maxim’s peripheral modules are also adaptable to other FPGA and microprocessor boards implementing PmodTM compatible expansion ports.

Availability and Pricing:

Modules supported by software for Avnet LX-9, Digilent Nexys™ 3 and Avnet ZEDBoard.

Modules operate at -40°C to +85°C.

Pricing for the entire collection of 15 modules is $89.95. Each module can be purchased individually—contact http://www.maxim-ic.com/ for unit pricing.
