Product details
Overview
CY8CLED16-28PVXIT from Cypress Semiconductor Corporation is a programmable System-on-Chip (PSoC) LED controller optimized for high-brightness (HB) LED lighting systems. It integrates an M8C 8-bit Harvard-architecture processor (24 MHz), supports up to 16 independent LED channels with 8–32-bit PWM resolution per channel, features PrISM™ modulation technology for EMI reduction and flicker suppression, and operates from 3.0–5.25 V (or down to 1.0 V via on-chip switch-mode pump). It is deployed in architectural lighting, LCD backlighting, and large-format signage requiring precise color and intensity control.
For engineers reviewing the CY8CLED16-28PVXIT datasheet, CY8CLED16-28PVXIT pinout, CY8CLED16-28PVXIT application, or CY8CLED16-28PVXIT equivalent, key selection criteria include per-channel PWM resolution configurability, integrated analog sensing (up to 8 GPIO with analog input), PrISM-based EMI-compliant dimming, and support for temperature/optical/binning compensation in closed-loop LED control systems.
Technical Context
The CY8CLED16-28PVXIT implements a dedicated HB LED control architecture built around Cypress's PSoC platform. Its digital system includes 16 configurable digital PSoC blocks enabling 8–32-bit PrISM modulators, PWMs with dead-band, timers, UARTs (up to 4), and SPI/I²C peripherals - all routable to any GPIO. The analog system comprises 12 rail-to-rail analog blocks supporting up to 14-bit ADCs, 9-bit DACs, programmable gain amplifiers, and comparators for real-time sensor feedback.
It employs PrISM™ (Precision Illumination Signal Modulation) as its core dimming methodology - a proprietary spread-spectrum PWM technique that shifts energy away from low-frequency harmonics to reduce radiated EMI and eliminate perceptible low-frequency blinking. The device also integrates a switch-mode pump (SMP) enabling operation from single-cell 1.2 V batteries, and supports industrial temperature range (–40 °C to +85 °C) with robust LVD and POR circuitry.

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-TR | Fixed-function 28-channel LED driver with I²C interface; no MCU, no PrISM, no analog sensing. | Limited to basic constant-current dimming; lacks closed-loop compensation, firmware customization, or DMX support. | Select when cost-sensitive, high-volume, fixed-feature LED arrays require minimal BOM count and no firmware development. |
| STM32F072CBT6 | ARM Cortex-M0 MCU with 12-bit ADC, 16-bit timers, and no native PrISM; requires external MOSFET drivers and analog front-end. | Requires additional components for LED current control and EMI mitigation; longer design cycle for custom PrISM-equivalent firmware. | Select when existing STM32 ecosystem, RTOS integration, or mixed-signal control beyond lighting is required. |
Compared with IS31FL3728-QFLS4-TR and STM32F072CBT6, the CY8CLED16-28PVXIT delivers integrated PrISM modulation, on-die analog sensing, and lighting-specific firmware libraries - reducing bill-of-materials, PCB area, and time-to-market for intelligent HB LED systems requiring flicker-free, thermally stable illumination.

FAQ
Does CY8CLED16-28PVXIT support I²C communication?
Yes. The device includes a dedicated I²C slave and multi-master module supporting 100 kHz and 400 kHz modes. It can act as an I²C slave for host microcontroller control or as a multi-master to interface with external sensors, EEPROMs, or other I²C peripherals without CPU intervention.
What is the maximum LED channel count supported in hardware?
The CY8CLED16-28PVXIT supports up to 16 independent LED channels in hardware, each configurable with PrISM or standard PWM output. All 16 channels can operate simultaneously at 8-bit resolution, or fewer channels at higher resolutions (e.g., 8 channels at 16-bit, 4 at 32-bit) depending on resource allocation in PSoC Designer.
Can the device operate from a single 1.2 V alkaline cell?
Yes. Its integrated switch-mode pump (SMP) boosts 1.0–1.2 V input to internal regulated rails, enabling full functionality-including 24 MHz CPU operation and PrISM modulation-from a single AA/AAA cell. This eliminates need for external DC-DC converters in portable LED lighting designs.
Is optical feedback implemented in hardware or firmware?
Optical feedback is implemented in firmware using the device's configurable analog blocks: up to 8 GPIO pins support analog input, and the onboard 14-bit ADC (with programmable gain amplifier) digitizes photodiode or ambient light sensor signals. PSoC Designer provides pre-verified "Optical Feedback" user modules for closed-loop intensity control without custom analog design.
