Product details

Overview

CY8CLED02-8SXI 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, 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 (24 MHz), 4 KB flash, 256 B SRAM, and configurable digital/analog PSoC blocks for lighting control in architectural and signage applications.

For engineers reviewing the CY8CLED02-8SXI datasheet, CY8CLED02-8SXI pinout, CY8CLED02-8SXI application, or CY8CLED02-8SXI equivalent, key selection criteria include PrISM-based EMI-reduced LED drive capability, binning/temperature/optical feedback support, dual-channel independent dimming resolution, and integration of UART/SPI/I²C plus analog peripherals (ADC/DAC/PGA) within a single 28-pin SOIC package.

Technical Context

The CY8CLED02-8SXI implements a dedicated PrISM™ (Precise Illumination Signal Modulation) engine for low-EMI, flicker-free HB LED current control-distinct from standard PWM-by dynamically varying switching frequency and duty cycle while maintaining constant average current. Its M8C core executes lighting-specific firmware in conjunction with four digital PSoC blocks (configurable as timers, PWMs, UART, SPI) and four analog PSoC blocks (supporting up to 10-bit ADC, 9-bit DAC, PGA, comparators).

Digital and analog resources are routed flexibly via global interconnect busses to 16 GPIO pins, enabling simultaneous implementation of LED control, temperature sensing, optical feedback processing, and I²C-based system communication-all without external components. The device supports in-system serial programming (ISSP) and partial flash updates for field firmware adaptation in deployed lighting systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar HB LED controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLC5940IPWP	16-channel 12-bit PWM driver with dot-correction; no MCU core, no PrISM, no analog sensing	Fixed-function LED driver only-requires external microcontroller for closed-loop feedback	Select when high channel count and simple PWM suffices; not suitable for PrISM EMI reduction or thermal compensation
IS31FL3728-QFLS4	28-channel matrix LED driver with built-in gamma correction and auto-breathing; no programmable CPU or analog peripherals	Designed for LED matrix displays-not optimized for high-current HB LED string control or sensor integration	Select for compact LED signage with preprogrammed effects; lacks real-time optical feedback or ISSP capability

Compared with TLC5940IPWP and IS31FL3728-QFLS4, CY8CLED02-8SXI uniquely combines programmable PrISM dimming, on-die analog sensing, and MCU-based closed-loop control in a single chip-enabling adaptive lighting without external controllers or signal conditioning circuitry.

FAQ

What is PrISM™ modulation and how does it differ from standard PWM?

PrISM™ (Precise Illumination Signal Modulation) is Cypress's proprietary dimming technique that varies both frequency and duty cycle dynamically to maintain constant average current while eliminating low-frequency flicker and reducing radiated EMI by spreading energy across a wider spectrum. Unlike fixed-frequency PWM, PrISM avoids harmonic peaks and enables compliance with FCC Class B emissions limits without external filtering components.

Does CY8CLED02-8SXI support closed-loop optical feedback?

Yes-CY8CLED02-8SXI supports closed-loop optical feedback via its configurable analog input channels (up to 8), integrated PGA, and 10-bit ADC. It can directly interface with photodiodes or ambient light sensors to measure luminance and adjust LED drive current in real time, enabling consistent brightness under varying ambient conditions or LED aging.

Can the device operate from a single 1.2 V battery cell?

Yes-the integrated switch-mode pump (SMP) boosts a 1.0–1.2 V input to the required 3.0–5.25 V operating rail, enabling direct use with single-cell Li-ion or NiMH batteries. This eliminates the need for external DC-DC converters in portable lighting and flash applications.

Is in-system programming supported without a JTAG interface?

Yes-CY8CLED02-8SXI supports In-System Serial Programming (ISSP) using only two wires (clock and data), allowing firmware updates in the final product without JTAG headers or dedicated debug connectors. This simplifies field upgrades and reduces PCB footprint versus JTAG-based solutions.
