Product details
Overview
CY8CLED04-68LFXI from Cypress Semiconductor is a programmable System-on-Chip (PSoC®) HB LED controller with PrISM™ modulation, supporting up to four independent LED channels at 8–32-bit resolution per channel, integrated 16 KB flash/1 KB SRAM, and full-speed USB 2.0 (12 Mbps) with no external crystal required. It delivers intelligent dimming for architectural lighting, LCD backlighting, and camera flash systems with binning compensation, temperature feedback, and optical feedback.
For engineers reviewing the CY8CLED04-68LFXI datasheet, CY8CLED04-68LFXI pinout, CY8CLED04-68LFXI application, or CY8CLED04-68LFXI equivalent, key selection criteria include PrISM™ EMI reduction capability, configurable analog/digital PSoC blocks, 68-pin TQFP package compatibility, and support for CapSense®, motor control, and battery charging co-integration.
Technical Context
The device integrates an M8C 8-bit Harvard-architecture CPU running up to 68 MHz with 20 interrupt vectors, paired with dual clock domains: a self-tuning 24 MHz IMO (±0.25% for USB) and a 32 kHz ILO for low-power operation. Its digital system comprises four configurable 8-bit PSoC blocks enabling user-defined peripherals including PrISM™ modulators, PWMs, UARTs, SPI/I²C masters/slaves, and CRC generators.
The analog system includes six rail-to-rail configurable analog blocks supporting up to two 14-bit ADCs, two 9-bit DACs, PGAs (gain up to 48×), comparators (16 thresholds), and high-current analog outputs (30 mA). All analog resources connect via a flexible analog mux bus supporting simultaneous dual-channel processing and capacitive sensing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar HB LED controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8CLED16-68LFXI | 16-channel LED control (vs. 4), same PrISM™, 32 KB flash, identical 68-pin TQFP package | Targets larger LED arrays (e.g., stadium lighting); higher channel count increases firmware complexity and power consumption | Select when >4 independent dimming channels are required; pin-compatible but requires revalidation of analog resource allocation |
| CY8C5868LTI-LP097 | PSoC 5LP ARM Cortex-M3 core, 256 KB flash, 64 KB SRAM, no PrISM™, supports UDB-based LED PWM only | Lacks native PrISM™ EMI suppression; requires custom firmware for flicker mitigation and lacks EZ-Color lighting-specific drivers | Choose for mixed-signal applications needing higher compute performance and USB HID support, not for EMI-sensitive LED installations |

FAQ
Does CY8CLED04-68LFXI require an external crystal for USB operation?
No. The device uses a self-tuning internal main oscillator (IMO) that achieves ±0.25% accuracy over temperature and voltage, meeting USB 2.0 full-speed timing requirements without external crystals or oscillators. Only two 27 Ω series resistors on the USB_DP/DM lines are required for compliance.
Can CY8CLED04-68LFXI support capacitive touch sensing alongside LED control?
Yes. Its analog multiplexer system and six configurable analog blocks enable concurrent CapSense® operation-using CT/SC blocks for delta-sigma capacitive measurement-while simultaneously driving up to four LED channels via PrISM™, with shared GPIO and interrupt resources managed in PSoC Designer.
What is the maximum resolution achievable per LED channel with PrISM™ modulation?
Each of the four LED channels supports configurable resolution from 8 bits to 32 bits. At 32-bit resolution, PrISM™ delivers >96 dB dynamic range and sub-1% duty-cycle granularity, enabling ultra-smooth dimming curves and precise color mixing in high-end architectural and display applications.
Is in-system programming supported, and what interface options are available?
Yes. In-system serial programming (ISSP) is supported via SWD or USB using PSoC Programmer. Partial flash updates allow field firmware revisions without erasing protected bootloader or calibration data. USB-based programming eliminates need for external debug probes in production environments.
