Product details
Overview
CY8CLED02-24LFXI from Cypress Semiconductor is a programmable System-on-Chip (PSoC®) LED controller optimized for high-brightness (HB) LED dimming with PrISM™ modulation, supporting 2 independent LED channels at 8–32-bit resolution per channel, operating from 3.0 V to 5.25 V (or down to 1.0 V via on-chip switch-mode pump), and rated for –40 °C to +85 °C industrial temperature range. It integrates an M8C 8-bit Harvard-architecture processor (up to 24 MHz), 4 KB flash, 256 Bytes SRAM, and configurable digital/analog PSoC blocks for lighting-specific signal conditioning and control.
For engineers reviewing the CY8CLED02-24LFXI datasheet, CY8CLED02-24LFXI pinout, CY8CLED02-24LFXI application, or CY8CLED02-24LFXI equivalent, this device serves as a fully integrated HB LED controller with embedded binning compensation, optical/temperature feedback support, DMX512 interface capability, and in-system serial programming (ISSP) for field firmware updates in architectural lighting and LCD backlight systems.
Technical Context
The CY8CLED02-24LFXI implements a dual-channel PrISM™ modulator for EMI-reduced, low-flicker LED drive, paired with four digital PSoC blocks enabling configurable 8–32-bit PWMs, timers, UART, SPI, and I²C peripherals. Its analog system includes four Type E analog blocks supporting up to 10-bit ADCs, comparators, and 1.3 V internal reference.
It features a flexible GPIO architecture with 25 mA sink / 10 mA source drive strength, programmable pull-up/pull-down/high-Z/open-drain modes, interrupt capability on all pins, and up to 12 analog inputs - all routed via global digital/analog interconnects decoupled from fixed peripheral mapping.

Equivalent & Alternatives
The following parts are listed as comparable options for similar HB LED controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS31FL3728-QFLS4 | 8-channel constant-current LED driver with I²C interface; no MCU core or PrISM™; fixed 8-bit PWM resolution | Lacks programmability, optical/temperature feedback, and binning compensation; suited for static multi-color signage only | Select when cost-sensitive, fixed-function 8-channel drive is sufficient and closed-loop control is unnecessary |
| STM32F072CBT6 | ARM Cortex-M0 MCU with 128 KB flash, 16 KB RAM, and advanced timers; requires external LED driver ICs and PrISM-like firmware implementation | Higher BOM count and development effort; supports broader system integration beyond lighting (e.g., motor + battery charging) | Select when multi-function system consolidation (e.g., LED + charging + sensing) justifies added software complexity and external components |
Compared with IS31FL3728-QFLS4 and STM32F072CBT6, CY8CLED02-24LFXI uniquely integrates PrISM™ modulation, binning compensation, and lighting-specific analog peripherals into a single chip-reducing component count, eliminating flicker-related certification risks, and enabling field-upgradable lighting algorithms without hardware change.

FAQ
Does CY8CLED02-24LFXI support DMX512 protocol natively?
No, it does not include a dedicated DMX512 transceiver, but its UART and configurable digital blocks enable robust DMX512 slave implementation via firmware - validated in Cypress Application Note AN2297. The device provides full UART framing, break detection, and slot timing control required for compliance with ANSI E1.11.
What is the maximum continuous LED current the device can drive directly?
CY8CLED02-24LFXI does not integrate high-side or low-side power switches; it drives external MOSFETs or LED driver ICs. Its GPIO pins support up to 25 mA sink per pin, intended for gate control or logic-level signaling - not direct LED current sourcing/sinking.
Can the PrISM™ modulation be disabled to use standard PWM instead?
Yes. PrISM™ is implemented as a configurable user module in PSoC Designer™; designers may select standard center-aligned or edge-aligned 8–32-bit PWM instead. However, disabling PrISM™ forfeits its EMI reduction and flicker elimination benefits - confirmed in Electrical Specifications section of datasheet Rev. *G, page 22.
Is there factory-programmed firmware included with CY8CLED02-24LFXI?
No. The device ships with blank flash memory. Production units require programming via ISSP using PSoC Programmer or third-party tools. Cypress provides reference firmware examples (e.g., binning-compensated dimmer, DMX slave) in the PSoC Solutions Library, but no bootloader or application code is preloaded.
