A customer's equipment used an operator control panel employing Denso D880 illuminated LCD keyswitches. The equipment was becoming unusable because these keyswitches were failing. They were obsolete and even reclaimed devices could not be obtained. Our solution was a redesign of the electronic modules containing them, based around SMARTSWITCHTM devices (IS-15 series) from NKK. Using an Actel A42MX series FPGA and modern ICs instead of the MSI, PALs and discrete devices used in the original design also had a beneficial impact on the power consumption of the replacenent module. The reduced size allowed the adoption of a single PCB in place of the stacked PCB construction employed previously. ASIC Solutions supplies assembled and tested modules through the OEM to the end users of the equipment.
