Understanding Complex Programmable Logic Devices
Complex programmable logic devices sit between programmable array logic and field-programmable gate arrays in terms of complexity, featuring programmable logic blocks and a non-volatile memory architecture. CPLDs excel in applications requiring instant-on capability, deterministic timing, and lower complexity logic functions such as signal interfacing, control functions, and glue logic in embedded systems.
For engineers designing systems where reliability and boot time matter, CPLDs offer lower signal propagation delay compared to FPGAs and consume less power during static operation. This makes them particularly valuable in battery-powered applications and systems requiring immediate operational readiness after power-up.
Featured CPLD Solutions Available Through TRX Electronics
Microchip ATF1504AS-7JX44
The ATF1504AS-7JX44 represents Microchip's high-performance CPLD offering with 64 macrocells and 7 ns maximum pin-to-pin delay. This device comes in a 44-lead PLCC package, providing flexibility for designs requiring moderate logic density with fast timing performance. The EEPROM-based non-volatile configuration storage ensures instant-on operation without external memory requirements.
Configurable macrocells function as registered or combinatorial logic, making this device suitable for control logic, state machines, and interface bridging applications. The compact PLCC package enables board space optimisation in space-constrained designs.

The EPM570T100A5N from Altera's MAX II family delivers enhanced logic density with 570 logic elements in a compact footprint. This device provides 100-pin TQFP packaging with industrial temperature range support, making it suitable for demanding environmental conditions. Non-volatile Flash memory technology enables instant-on operation whilst MultiVolt I/O support facilitates interfacing with different voltage standards.
The MAX II architecture uses Logic Array Blocks interconnected through a Programmable Interconnect Array, enabling flexible routing for implementing complex functions. Hot-socketing capability allows boards to be inserted or removed from live backplanes without damaging the device, valuable for maintenance scenarios in industrial equipment.
Industrial and Consumer Applications
Industrial Automation and Control
CPLDs serve as integral components in Programmable Logic Controllers, enabling implementation of custom logic, safety interlocks, and communication interfaces to interact with various sensors and actuators. Factory automation systems benefit from CPLDs' ability to handle real-time control requirements whilst supporting PLCs, robotics controllers, and process automation units.
Devices with moderate macrocell counts find application in motor control interfaces, sensor signal conditioning, and programmable timers. The instant-on characteristic ensures production equipment becomes operational immediately upon power restoration.
Automotive Electronics
In automotive applications, CPLDs are deployed in engine control units for fuel injection timing control, safety systems including airbag deployment and antilock braking systems, and advanced driver assistance systems. Automotive implementations include infotainment systems, body electronics, and dashboard logic modules, where instant-on capability ensures immediate system availability upon vehicle start-up.
Industrial temperature range specifications and robust I/O capabilities make certain CPLD families suitable for harsh automotive environments where temperature extremes and electrical noise present challenges.
Telecommunications and Consumer Electronics
CPLDs implement high-speed serial interfaces such as PCIe, USB, and Gigabit Ethernet for telecommunications equipment. The deterministic timing characteristics make them suitable for applications where predictable latency matters for maintaining signal integrity. Fast pin-to-pin delays enable high-speed data path implementations for protocol conversion and interface bridging.
In consumer electronics, CPLDs handle interface management for display panels and audio processing whilst serving in set-top boxes, home automation systems, and gaming consoles. The compact size and re-programmability make them attractive for space-constrained products where manufacturers value the ability to update logic functions during development.

Frequently Asked Questions
What distinguishes CPLDs from FPGAs for my application?
CPLDs offer lower signal propagation delay and instant-on operation with non-volatile configuration storage, making them suitable for applications requiring fast response times and immediate availability after power-up. FPGAs provide greater logic capacity for more complex designs but typically require external configuration memory. CPLDs excel in control logic, interface bridging, and applications where deterministic timing matters most.
