Product details
Overview
CY8CLED16-28PVXI from Cypress Semiconductor is a programmable System-on-Chip (PSoC) HB LED controller with M8C 8-bit Harvard-architecture CPU running at up to 24 MHz, supporting 16 independent LED channels with 8–32-bit dimming resolution per channel, PrISM™ modulation for EMI reduction, and integrated analog/digital peripherals including 14-bit ADCs and 9-bit DACs. It targets intelligent high-brightness LED lighting systems requiring binning compensation, temperature feedback, and optical closed-loop control.
For engineers reviewing the CY8CLED16-28PVXI datasheet, CY8CLED16-28PVXI pinout, CY8CLED16-28PVXI application, or CY8CLED16-28PVXI equivalent, key selection criteria include configurable LED channel count, PrISM-based flicker suppression, on-chip switch-mode pump for 1.0 V operation, rail-to-rail analog block flexibility, and PSoC Designer™ toolchain integration for lighting-specific firmware development.
Technical Context
The device implements a mixed-signal PSoC architecture with 16 digital and 12 analog configurable blocks, enabling user-defined peripherals such as PrISM modulators, PWMs with dead-band, Delta-Sigma ADCs, and programmable gain amplifiers-all routable to any GPIO. Clocking includes 24 MHz IMO (±2.5%), 32 kHz ILO, and optional 32.768 kHz ECO with PLL for crystal-accurate timing.
PrISM™ technology replaces conventional PWM by dithering LED current at high frequency while preserving perceived brightness and color fidelity-reducing low-frequency flicker and radiated EMI without external filtering. The on-chip switch-mode pump enables operation down to 1.0 V supply, supporting single-cell battery-powered LED drivers.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS31FL3731-QFLS4-TR | Fixed-function 18-channel LED driver with I²C interface; no MCU, no PrISM, no analog ADC/DAC | Limited to basic PWM dimming; lacks temperature/optical feedback processing and firmware customization | Select when cost-sensitive, low-complexity LED matrix control is required without closed-loop adaptation |
| STM32F072CBT6 | ARM Cortex-M0 MCU with 12-bit ADC, no integrated PrISM, no dedicated LED driver hardware | Requires external MOSFET drivers and custom firmware for LED control; higher BOM and development effort | Select when existing STM32 ecosystem use, RTOS integration, or non-LED peripherals (USB, CAN) dominate system requirements |

FAQ
What is PrISM™ modulation and how does it differ from standard PWM?
PrISM™ (Precise Illumination Signal Modulation) is Cypress's proprietary LED dimming technique that dithers current at high frequency while maintaining constant average current-eliminating visible flicker and reducing EMI without external filters. Unlike PWM, which switches full current at low frequencies (100–2000 Hz), PrISM operates above 20 MHz and preserves color point stability under varying thermal conditions.
Does CY8CLED16-28PVXI support closed-loop optical feedback?
Yes. The device integrates up to four 14-bit ADCs and programmable comparators that accept photodiode or ambient light sensor signals. Combined with PSoC Designer's lighting firmware libraries, it enables real-time luminance regulation by dynamically adjusting PrISM duty cycle based on optical feedback-without external microcontroller intervention.
Can CY8CLED16-28PVXI operate from a single 1.2 V alkaline cell?
Yes. Its integrated switch-mode pump (SMP) boosts 1.0–1.2 V input to regulated 3.3 V for internal circuitry, enabling operation from one AA/AAA cell. The SMP drives an external inductor and capacitor; typical efficiency exceeds 85% at 10 mA load, supporting battery-powered flashlights and portable signage.
Is PSoC Designer software still supported for CY8CLED16 development?
Yes. Cypress provides legacy PSoC Designer v5.4 SP4 with full CY8CLED16 device support, including EZ-Color lighting modules, PrISM configuration wizards, and binning compensation templates. Infineon maintains archived downloads and application notes for continued development, though new designs are encouraged to evaluate PSoC 4/6 alternatives.
