Product details

Overview

CY8CLED02-16SXI from Cypress Semiconductor is a programmable System-on-Chip (PSoC®) HB LED controller with M8C 8-bit Harvard-architecture processor (24 MHz), 4 KB flash, 256 Bytes SRAM, and support for two independent LED channels using PrISM™ modulation. It operates from 3.0 V to 5.25 V (or down to 1.0 V via on-chip switch-mode pump), features 8–32-bit dimming resolution per channel, and integrates analog peripherals including 10-bit ADCs and PGAs. Used in LCD backlighting and architectural lighting systems requiring binning compensation and temperature feedback.

For engineers reviewing the CY8CLED02-16SXI datasheet, CY8CLED02-16SXI pinout, CY8CLED02-16SXI application, or CY8CLED02-16SXI equivalent, this page provides verified technical context, validated pin functions, confirmed PrISM-based EMI reduction capability, real-world dimming resolution ranges, and documented integration of optical/thermal feedback loops - all critical for intelligent HB LED system design.

Technical Context

The CY8CLED02-16SXI implements a configurable digital system built around four digital PSoC blocks, each supporting 8–32-bit PrISM, PWM, timers, UART, SPI, and I²C (master/slave/multi-master). These blocks route signals flexibly across 16 GPIO pins via global digital interconnect busses.

Its analog subsystem comprises four Type E analog blocks (2 CT + 2 SC), enabling 10-bit ADCs, comparators with 1.3 V reference, and PGA-based signal conditioning - all programmable to support closed-loop LED current regulation using temperature or optical feedback inputs.

Key Specifications

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	Fixed-function 8-channel LED driver with I²C interface; no embedded processor or PrISM; 8-bit PWM only	Lacks programmability, temperature/optical feedback, and binning compensation - suitable only for static, non-adaptive LED arrays	Select when cost-sensitive, low-complexity designs require only basic dimming without closed-loop control
STM32F072CBT6	ARM Cortex-M0 MCU (48 MHz), 128 KB flash, no native PrISM; requires external LED driver ICs and analog front-end	Higher processing headroom but adds component count, layout complexity, and firmware development effort for LED-specific functions	Select when system requires additional peripherals (USB, CAN) beyond LED control, and engineering bandwidth exists for full custom driver stack

Compared with IS31FL3728-QFLS4 and STM32F072CBT6, the CY8CLED02-16SXI delivers integrated PrISM modulation, on-die analog sensing, and pre-validated lighting algorithms - reducing time-to-market for adaptive HB LED systems by eliminating external signal conditioning and custom PWM timing logic.

FAQ

What is the maximum LED channel count supported by CY8CLED02-16SXI?

The CY8CLED02-16SXI supports exactly two independent LED channels, as confirmed in Table 1 (EZ-Color Device Characteristics) of its datasheet (Doc #001-13704 Rev. *G). Each channel supports configurable PrISM or PWM output with 8–32-bit resolution, and both channels can be driven simultaneously with independent dimming profiles and feedback paths.

Does CY8CLED02-16SXI include an internal voltage regulator for analog blocks?

Yes - it integrates a 1.3 V internal voltage reference used by ADCs, DACs, and comparators, as stated in the "Additional System Resources" section (page 4) and confirmed in the "Electrical Specifications" table (page 15). This reference is stable across temperature and supply voltage, eliminating need for external precision references in closed-loop LED current control.

Can CY8CLED02-16SXI operate from a single 1.2 V alkaline or NiMH cell?

Yes - its on-chip switch-mode pump (SMP) boosts 1.0–1.2 V input to internal operating rails (3.0–5.25 V), enabling direct single-cell battery operation. This is explicitly specified in the "Features" list and "Operating Voltage" section (page 14), and validated by the absolute minimum supply rating of 1.0 V under SMP-enabled mode.

Is ISSP supported for firmware updates in the field?

Yes - In-System Serial Programming (ISSP) is fully supported via two-wire interface (clock and data), allowing firmware updates without device removal. This is documented in the "Flexible on-chip memory" feature list and detailed in the "Development Tools" section (page 6), with hardware support provided by standard Cypress programmers like MiniProg3.
