XC2C64A-7QFG48I Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic device that sits between discrete glue logic and FPGAs in the programmable logic hierarchy (CPLD -> PLD -> programmable logic -> digital IC -> semiconductor). CoolRunner-II devices implement logic in function blocks based on PLA (Programmable Logic Array) sub-blocks with macrocell flip-flops, providing deterministic timing that simplifies design sign-off in glue-logic applications.
Key features of the XC2C64A-7QFG48I include 64 macrocells organized as 4 logic blocks of 16 macrocells, 33 usable I/O pins (out of 37 total), 1.5K usable gates, a pin-to-pin delay of 4.6 ns at industrial temperature range, and DataGATE technology for per-pin input signal blocking to reduce dynamic power. The 0.18 µm CMOS process enables 1.8V core operation with I/O tolerance to 3.3V signals, simplifying interfacing with legacy 3.3V peripherals.
The architecture combines a deterministic timing model with low-power 1.8V operation, making this CPLD well-suited for portable and battery-powered designs. The internal 1.8V VCCINT and I/O banked VCCIO supply rails permit mixed-voltage signaling without external level shifters, while the four global clock networks and per-macrocell OE controls give designers flexible clocking and bus-management options.
Typical applications include portable/battery-powered consumer electronics where low quiescent current matters, industrial control I/O expansion and bus bridging (I2C, SPI, UART glue logic), and telecom infrastructure glue logic interfacing 3.3V peripherals to 1.8V processors. Designers also deploy this part in medical handheld devices and white goods motor control boards.
When designing with this device, ensure the JTAG chain length and TDO load remain within specifications if multiple CoolRunner-II parts share one chain. The DataGATE feature can be disabled per pin to preserve dynamic behavior on critical paths; verify per-pin signal integrity when chaining long busses.

Typical Applications
XC2C64A-7QFG48I is suitable for 6 applications: Portable Consumer Electronics, Industrial I/O Expansion & Bus Bridging, Telecom Infrastructure Glue Logic, Medical Handheld Devices, White Goods Motor Control, Aerospace and Drone Flight Controllers.
Portable Consumer Electronics
The XC2C64A-7QFG48I fits portable consumer electronics because of its 1.8V core operation and typical 15 µA quiescent current. With 64 macrocells and 33 usable I/O, the device provides ample capacity for power-management sequencing, LED/PWM generation, and user-interface glue logic. The DataGATE feature selectively blocks switching on inactive input pins, reducing dynamic power consumption by up to 50% in typical designs.
Recommended
Industrial I/O Expansion & Bus Bridging
The XC2C64A-7QFG48I is ideal for industrial I/O expansion and bus-bridging applications that interface a 1.8V host processor with legacy 3.3V peripherals. Its VCCIO bank supports 1.5V, 1.8V, 2.5V, and 3.3V signaling, eliminating external level shifters. The 4.6 ns pin-to-pin delay supports SPI, I2C, and UART bridging up to 159 MHz system frequency, while JTAG-based ISP enables field firmware updates in deployed equipment.
Recommended
Telecom Infrastructure Glue Logic
In telecom infrastructure, the XC2C64A-7QFG48I serves as deterministic glue logic between ASICs, FPGAs, and backplane transceivers. The CoolRunner-II architecture provides predictable timing that simplifies design sign-off, while non-volatile flash configuration ensures instant-on behavior critical for hot-swap and redundant systems. The 33 usable I/O pins cover typical board-management functions like watchdog strobing, status-LED multiplexing, and reset distribution.
Recommended
Medical Handheld Devices
Medical handheld devices benefit from the XC2C64A-7QFG48I's combination of low quiescent current (~15 µA), industrial temperature range (-40C to +85C), and small 48-pin QFN footprint. The device handles signal-routing logic between the host MCU and sensor front-ends, while its 1.8V core minimizes overall system power. Non-volatile flash storage ensures instant-on start, important for clinician-facing diagnostic equipment that cannot tolerate boot delays.
Recommended
White Goods Motor Control
The XC2C64A-7QFG48I fits white-goods motor-control boards as glue logic between the host MCU and gate drivers, sensors, and user-interface peripherals. Its deterministic 4.6 ns timing suits real-time control loops, and the wide VCCIO range (1.5-3.3V) simplifies interfacing with mixed-voltage subsystems. Industrial temperature grade and QFN thermal performance support continuous operation near motor hot-spots.
Recommended
Aerospace and Drone Flight Controllers
In drone flight controllers, the XC2C64A-7QFG48I provides fast deterministic glue logic for sensor aggregation and protocol translation. Its 4.6 ns propagation delay handles high-rate SPI sensor reads (gyros, accelerometers) and PWM generation for ESC control. The small 48-pin QFN footprint and low power consumption support weight-sensitive and battery-constrained airframes.

Key Differentiators
- Lowest-power 48-pin QFN CPLD in CoolRunner-II family (vs XC2C64A-7QFG48C)
- Same die/package as commercial variant, with industrial temperature validation (vs XC2C64A-7VQG48I)
- Reduced thermal footprint in QFG vs VQFP package (vs XC2C64A-7VQG44I)
Design Notes
Estimated: The XC2C64A-7QFG48I requires two supply rails - VCCINT (1.8V) for the core and VCCIO (1.5V to 3.3V) for I/O banks. Decoupling requires a 0.1 µF ceramic capacitor placed within 5 mm of each VCCINT pin, and a 1 µF bulk capacitor on each VCCIO bank. Power-on reset requires VCCINT to ramp monotonically to 1.8V in less than 1 ms; use a supervisor IC such as TPS3106K33DBVR to enforce this if the upstream rail has unknown behavior.
The 48-pin QFG/QFN package has an exposed thermal pad (pin 48) that must be soldered to a 0.5 mm × 0.5 mm land area on the PCB for both thermal and electrical performance. The thermal pad should be connected to a ground plane via 9 thermal vias in a 3×3 grid. Without proper soldering to the EP, the device may exhibit elevated junction temperatures and degraded I/O performance.
The DataGATE feature must be explicitly disabled (default OFF in most designs) for pins that need transparent input behavior - leaving it enabled by default can block legitimate input transitions on unused pins. JTAG chain isolation requires 4.7 kΩ pull-ups on TDI and TMS to prevent spurious entry into programming mode during power-up. Always use Xilinx iMPACT or Vivado 6.x legacy tools for programming, as newer Vivado releases may not include CoolRunner-II support.
