ICE40LP640-CM81

The ICE40LP640-CM81 is an ultra-low-power iCE40™ LP series Field Programmable Gate Array (FPGA) provided in an 81-ball chip-scale BGA package. It delivers 640 logic elements, 32 Kbits of on-chip RAM, and up to 63 programmable I/O, making it suitable for compact, low-power digital logic and interface tasks.

Designed as part of the LP Series optimized for low power and mobile-targeted applications, this device combines a small footprint, an integrated phase-locked loop (PLL), and industrial-grade operating range to serve mobile, display, and industrial embedded applications.

Key Features

• Core Logic  640 logic elements (LUT + flip-flop) for implementing combinational and sequential logic functions.
• Embedded Memory  32 Kbits (32,768 bits) of on-chip RAM organized as RAM4K blocks for small FIFO, buffer, and lookup storage.
• I/O  Up to 63 programmable I/O pins to support a variety of peripheral interfaces and signal routing.
• Integrated PLL  Includes a Phase-Locked Loop with family capability up to 533 MHz output for clock multiplication/division useful in display, SerDes, and memory interfaces.
• Low-Power Operation  Part of the LP ultra-low-power family with typical core standby current of 35 µA at 0 kHz (family characteristic) and a low core supply range of 1.14 V to 1.26 V.
• Package & Mounting  81-ball chip-scale BGA (81-VFBGA / supplier package 81-UCBGA, 4×4 mm footprint, 0.4 mm pitch) for compact surface-mount mounting.
• Industrial Temperature Grade  Rated for operation from –40 °C to 100 °C to meet extended-environment requirements.
• Reprogrammable & Tool Support  Reprogrammable device supported by the iCEcube2 development flow with VHDL and Verilog synthesis, place-and-route, and IP core libraries (family tooling referenced in datasheet).
• Compliance  RoHS compliant.

Typical Applications

• Mobile and Handheld Devices  Low-power, small-footprint FPGA functions for mobile convergence and handheld logic where energy and board area are constrained.
• Display and Video Interfaces  Clock multiplication and interface logic for display and HD video image pathways using the integrated PLL and programmable I/O.
• SerDes and Memory Interfaces  Clocking and protocol bridging for memory and serial interfaces enabled by PLL-based clocking and flexible I/O.
• Industrial Embedded Logic  Compact, industrial-grade programmable logic for sensor interfacing, control logic, and protocol conversion across –40 °C to 100 °C.

Unique Advantages

• Ultra-low-power architecture: The LP-series design and low core supply range (1.14 V–1.26 V) provide low standby and operating currents for power-sensitive designs.
• Integrated clock management: On-chip PLL capability (family support up to 533 MHz) reduces the need for external clock synthesis components.
• Compact, board-friendly package: 4×4 mm 81-ball chip-scale BGA enables space-constrained PCB layouts while delivering up to 63 I/O.
• Industrial temperature rating: –40 °C to 100 °C operation supports robust operation in extended-environment applications.
• Ready development ecosystem: Support for iCEcube2 with VHDL/Verilog synthesis and IP libraries accelerates design implementation and verification.
• RoHS compliant: Complies with RoHS environmental requirements.
