ICE40LP1K-CB121

The ICE40LP1K-CB121 is a low-power, non-volatile Field Programmable Gate Array (FPGA) IC from the iCE40 LP family. It provides 1,280 logic elements, approximately 64 Kbits of embedded RAM, and up to 92 programmable I/O in a compact 121-CSBGA (6×6 mm) surface-mount package.

Designed for industrial-grade applications, the device targets low-cost, high-volume consumer and system designs that demand low standby power, flexible I/O, on-chip memory, and embedded configuration options.

Key Features

• Core Logic — 1,280 logic elements suitable for small to mid-density programmable logic tasks and glue‑logic integration.
• Embedded Memory — Approximately 64 Kbits of on-chip RAM for buffering, small data tables, and state storage.
• I/O Versatility — 92 programmable I/O pins with family-level support for LVCMOS (3.3/2.5/1.8), LVDS25E, subLVDS and programmable pull-up modes.
• Low-Power Operation — Built on an advanced low-power process with family-documented ultra-low standby currents (example: as low as 21 μA standby power for the family).
• Clocking — On-chip PLL resources available for the LP1K device to support system clocking needs.
• LED Drivers — High-current LED drivers on the iCE40 family suitable for driving three discrete LEDs or a single RGB LED.
• Configuration Options — SRAM-based configuration with support for internal non-volatile configuration memory (NVCM) or standard SPI configuration methods (family capability).
• Package & Mounting — 121-VFBGA / 121-CSBGA (6×6 mm) surface-mount package, enabling compact PCB integration.
• Supply & Temperature — Operates from a core supply of 1.14 V to 1.26 V and rated for industrial temperature range of −40 °C to 100 °C.
• Compliance — RoHS compliant.

Typical Applications

• Portable and Battery-Powered Devices — Low standby current and small package size make it suitable for energy-sensitive portable modules and wearables.
• Consumer Electronics — On-chip LED drivers and flexible I/O support user-interface control, indicator LEDs, and simple display timing functions.
• IoT and Sensor Hubs — Embedded RAM and configurable I/O enable sensor aggregation, preprocessing, and interface bridging in compact designs.
• Industrial Controls — Industrial temperature rating and compact footprint allow deployment in control and monitoring modules exposed to wider temperature ranges.

Unique Advantages

• Compact, PCB-Friendly Package: 121-CSBGA (6×6 mm) provides a small footprint for space-constrained designs.
