ICE40UL640-CM36AI

The ICE40UL640-CM36AI is an industrial‑grade iCE40 UltraLite™ Field Programmable Gate Array (FPGA) featuring 640 logic elements and approximately 57,344 bits of embedded RAM. It provides a compact, surface‑mount solution in a 36‑VFBGA (36‑ucBGA, 2.5 mm × 2.5 mm) package with 26 user I/Os.

Built around the iCE40 UltraLite family architecture, the device targets ultra‑low power, small‑form‑factor designs and includes on‑chip oscillators, hardened LED/IR driver logic, on‑chip configuration options, and low standby current for always‑on sensor and interface management applications.

Key Features

• Logic Capacity 640 logic elements providing compact programmable logic; device organization also lists 80 CLBs for architectural partitioning.
• Embedded Memory Approximately 56 kbits of on‑chip Block RAM (57,344 bits) for buffering, state storage, and small data structures.
• I/O and Package 26 programmable I/O pins in a 36‑VFBGA package (supplier package: 36‑ucBGA, 2.5 mm × 2.5 mm), optimized for small footprint surface‑mount applications.
• Ultra‑Low Power Operation Designed on a low‑power process with typical standby current around 35 μA (≈42 μW), supporting always‑on use cases.
• On‑Chip Clocking Two internal oscillators (10 kHz LFOSC and 48 MHz HFOSC) plus a PLL and multiple low‑skew global clock resources for flexible clocking schemes.
• Hardened Peripherals Integrated RGB PWM logic with 24 mA current sinks, hardened TX/RX pulse logic for IR, a 400 mA IR driver (combinable to 500 mA), and a 100 mA barcode emulator driver.
• Interfaces and Configuration Optional FIFO‑mode I²C interface up to 1 MHz and flexible configuration via standard SPI or internal Nonvolatile Configuration Memory (NVCM).
• Operating Range Supply voltage 1.14 V to 1.26 V and operating temperature range −40 °C to 100 °C for industrial environments.
• Mounting Surface‑mount device suitable for automated assembly in compact systems.

Typical Applications

• Mobile and Handheld Interfaces Always‑on sensor management, service LED control, and simple protocol bridging where low standby power and small size are required.
• IoT and Sensor Hubs Local aggregation and preprocessing of sensor data using on‑chip memory and low‑frequency oscillator for ultra‑low power monitoring.
• IR Remote and Barcode Emulation Direct IR LED drive and barcode emulator outputs enable compact implementations of remote control and barcode scanning interfaces.
• RGB Indicator and Lighting Control Hardened RGB PWM with selectable sink currents for driving status or indicator LEDs without external MOSFETs or buffers.

Unique Advantages

• Highly integrated I/O drivers: Built‑in RGB, IR and barcode drivers reduce external component count and simplify BOMs for LED and IR applications.
• Small footprint packaging: 36‑ball ucBGA (2.5 mm × 2.5 mm) enables high‑density board layouts and compact product designs.
• Low standby power: Typical standby current around 35 μA supports always‑on functions while minimizing power draw.
• Flexible configuration options: Standard SPI programming or internal NVCM provides design flexibility for different manufacturing and field update workflows.
• Designed for industrial environments: −40 °C to 100 °C operating range and surface‑mount package suitable for rugged embedded systems.
• Embedded memory and clocking: On‑chip Block RAM and dual oscillators allow compact implementations without relying on extensive external resources.
