Key Features
- 64 macrocells with 4 configurable logic array blocks (LABs) for state-machine and glue-logic implementation
- 100 MHz maximum operating frequency supports real-time I/O multiplexing and bus arbitration in industrial systems
- JTAG in-system programmable (ISP) interface enables field reconfiguration without circuit board rework or device replacement
Applications
The EPM7064AETC44-10N serves as a bridge logic controller in legacy industrial automation systems, SCADA remote terminal units (RTUs), and embedded measurement equipment requiring flexible state-machine logic without microcontroller overhead. Its 36 I/O pins enable direct interfacing with analog multiplexers, relay driver arrays, and sensor conditioning circuits in -40°C to +85°C factory floor environments. The JTAG ISP capability allows field technicians to reprogram control sequences via laptop without removing the CPLD or disrupting the deployed system, reducing maintenance downtime from 4 hours to 15 minutes and minimizing spare parts inventory for critical infrastructure.

Frequently Asked Questions
How many logic cells and I/O pins does the EPM7064AETC44-10N provide for industrial state-machine design?
The EPM7064AETC44-10N integrates 64 macrocells organized into 4 logic array blocks (LABs), delivering approximately 600 equivalent NAND gates of logic density with 36 configurable I/O pins and 4 dedicated inputs. In an industrial traffic signal controller requiring 8 independent 4-state machines (red-yellow-green-flashing), each state machine consumes 8-12 macrocells, leaving 10 macrocells for I/O multiplexing and cross-module communication logic—sufficient for 2 concurrent systems with full timing flexibility.
What advantage does the EPM7064AETC44-10N's 100 MHz operating frequency provide for real-time PLC analog multiplexing?
The EPM7064AETC44-10N's 100 MHz clock enables sub-microsecond state transitions and 10 nanosecond signal propagation delays, allowing a 16-channel analog multiplexer to sequence through all channels in 1.6 microseconds at 100 kHz sample rate. This timing budget accommodates 8-bit ADC settling time (1 µs) plus signal routing delays, enabling simultaneous 10-channel monitoring at 10 kHz bandwidth per channel in compact TQFP-44 footprint (12 mm × 12 mm × 1.4 mm) without external timing controllers or FPGA overkill.
Can the EPM7064AETC44-10N replace discrete logic ICs in legacy RS-485 serial gateway cards for factory retrofit?
Yes. The EPM7064AETC44-10N's 64 macrocells replace approximately 8-12 discrete 74HC-series logic ICs (AND/OR/multiplexer gates), consolidating a 4-layer RS-485 interface adapter onto a single 44-pin package. Its JTAG ISP programmability allows field repair technicians to reprogram the protocol layer (Modbus RTU, Profibus-DP, or legacy Detroit Diesel gateway formats) on-site without component substitution, reducing spares inventory from 6 card variants to 1 universal card and shortening field repair time from 3 days to 30 minutes.
