ICE40LP1K-CM121

The ICE40LP1K-CM121 is an iCE40™ LP series Field Programmable Gate Array (FPGA) in a 121-VFBGA / csBGA package targeted at low-power, highly integrated embedded designs. It combines 1,280 logic elements with approximately 65 Kbits of embedded RAM and up to 95 I/O pins, providing a compact, low-power programmable fabric suitable for industrial and consumer system applications.

This device is built for ultra-low power operation and flexible I/O and clocking options, making it well suited for functions such as interface bridging, sensor aggregation, LED control and compact control logic in constrained power and space envelopes.

Key Features

• Logic Capacity — 1,280 logic elements (LUT + flip-flop) for implementing glue logic, protocol bridges and compact state machines.
• Embedded Memory — Approximately 65 Kbits of on-chip RAM (sysMEM) to support local buffering, small FIFOs and lookup tables.
• I/O Flexibility — Up to 95 programmable I/O pins with support for a wide range of signaling options from the iCE40 family.
• Ultra Low Power — Built on a 40 nm low-power process with standby currents as low as 21 μA (family data), enabling energy-conscious designs.
• Programmable I/O Buffer — sysIO™ buffer options and programmable pull-up modes for adaptable interfacing and input conditioning.
• Clocking — Eight low-skew global clock resources and support for up to two analog PLLs (family capability) for flexible clock management.
• High-Current LED Drivers — Three high-current drivers suitable for driving multiple LEDs or an RGB LED (family feature available on LP devices).
• Configuration Options — SRAM-based configuration with support for standard SPI and internal nonvolatile configuration memory (NVCM) as provided by the iCE40 family.
• Package and Mounting — 121-VFBGA (csBGA) surface-mount package, supplier device package 121-UCBGA (5×5 mm), compact for space-constrained PCBs.
• Supply and Temperature — Operates from a 1.14 V to 1.26 V supply and in an industrial temperature range of −40 °C to 100 °C.
• RoHS Compliant — Manufactured to meet RoHS environmental requirements.

Typical Applications

• Consumer and Portable Devices — Low-power programmable logic for sensor aggregation, protocol bridging and compact control tasks in battery-sensitive devices.
• LED and Display Control — Direct drive capability for RGB or multi-LED indicators using the on-chip high-current LED drivers.
• Industrial Control and Instrumentation — Industrial-grade operating range and flexible I/O for control logic, interface translation and status monitoring.
• Board-Level Glue and Protocol Conversion — Implement custom protocol bridges, timing adapters and small state machines to reduce BOM and simplify designs.

Unique Advantages

• Low-power operation: Family-level standby currents as low as 21 μA and a 40 nm low-power process help extend battery life and reduce thermal load.
• Compact, integrated solution: Combines logic, embedded RAM and programmable I/O in a single 121-VFBGA package to reduce board space and BOM count.
• Flexible interfacing: Up to 95 I/Os and programmable sysIO™ buffers allow adaptation to a variety of signaling standards without external translator ICs.
• On-chip resources for timing: Multiple global clock resources and available PLLs support disciplined clock distribution and simple SERDES or DDR register use cases.
• Industrial temperature range: Qualified for −40 °C to 100 °C operation to support deployed industrial systems.
• Nonvolatile configuration options: Support for internal NVCM and standard SPI configuration simplifies system start-up and field updates.
