Product details
Overview
CY8C28403-24PVXIT from Infineon Technologies (formerly Cypress Semiconductor) is a programmable System-on-Chip (PSoC® 1) integrating an M8C 8-bit Harvard-architecture CPU, 16 KB flash, 1 KB SRAM, up to 12 digital PSoC blocks, and up to 16 analog PSoC blocks - all operating at up to 24 MHz with 3.0–5.25 V supply. It supports rail-to-rail analog functions including 14-bit SAR ADC (142 ksps), programmable gain amplifiers, and capacitive sensing, deployed in industrial control HMI and sensor interface modules.
For engineers reviewing the CY8C28403-24PVXIT datasheet, CY8C28403-24PVXIT pinout, CY8C28403-24PVXIT application, or CY8C28403-24PVXIT equivalent, key selection criteria include verified 24 MHz M8C core timing, 14-bit ADC sample rate, analog block configurability, GPIO drive strength (25 mA sink), and I²C master/slave support up to 400 kHz - all confirmed in Infineon's Rev. *Q datasheet (001-48111).
Technical Context
The device implements a fixed-function yet reconfigurable architecture where digital and analog resources are interconnected via global digital/analog buses, enabling custom peripheral synthesis without external components. Its M8C core executes instructions at up to 24 MHz with 8×8 multiply and 32-bit accumulate capability, while internal clocks include ±2.5% accurate 24/48 MHz IMO and optional 32.768 kHz ECO for RTC-grade timing.
Analog subsystems support simultaneous operation of multiple ADC configurations (SAR + delta-sigma), programmable filters, comparators with DAC references, and dual-channel capacitive sensing - all mapped to configurable GPIOs with analog input capability and 30 mA analog output drive. Digital peripherals include up to three full-duplex UARTs, six half-duplex UARTs, and two hardware I²C resources supporting slave/master/multi-master modes.

Use Value: Integrates CapSense®, 14-bit ADC, and 16-bit PWM in one die - reduces component count by ≥7 parts versus discrete MCU + touch controller + ADC solution. | Use Scenario: Battery-powered environmental monitor measuring temperature, humidity, and ambient light with wireless data upload. IC Role / Device Role / Timing Role: Performs analog front-end conditioning, sensor digitization, low-power sleep/wake scheduling, and I²C communication with external transceiver. Use Value: On-chip 1.5 V SMP enables operation down to single-cell Li-ion voltage; 1 KB SRAM retains calibration data during deep sleep. |
| Motor Control Interface | Legacy Bus Bridge |
Use Scenario: Compact add-on board converting analog setpoints and encoder feedback into PWM motor drive signals for DC brush motors. IC Role / Device Role / Timing Role: Executes closed-loop PID using 24 MHz M8C core, generates synchronized PWM outputs with dead-band, and reads quadrature encoder inputs via digital blocks. Use Value: Configurable digital blocks implement 32-bit counters and phase-correct PWM - avoids FPGA or dual-IC solutions for cost-sensitive OEMs. | Use Scenario: Protocol translator between 5 V RS-232 serial port and I²C-based sensor cluster in building automation gateway. IC Role / Device Role / Timing Role: Implements UART-to-I²C bridge firmware with hardware UART and dual I²C masters, handling address translation and packet framing. Use Value: Two independent hardware I²C resources allow concurrent access to multiple sensor sub-buses - eliminates software bit-banging latency and timing jitter. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C28423-24PVXIT | Same package and core, but reduced analog block count (12 vs. 16) and no delta-sigma ADC support. | Suitable for simpler analog tasks like basic ADC + CapSense only - not for multi-ADC concurrent acquisition. | Select when design uses ≤12 analog blocks and does not require synchronized delta-sigma conversion. |
| CY8C29466-24PVXI | Higher resource count: 32 KB flash, 2 KB SRAM, 24 digital + 24 analog blocks; same 24 MHz M8C core. | Targets complex mixed-signal applications requiring larger code footprint and more parallel peripherals. | Choose for designs needing >16 KB flash or >16 analog blocks - e.g., multi-channel data loggers with FFT processing. |
Compared with CY8C28423-24PVXIT and CY8C29466-24PVXI, the CY8C28403-24PVXIT provides optimal balance of analog flexibility (16 blocks, 14-bit SAR + delta-sigma) and cost for mid-tier industrial interfaces - offering full feature parity with CY8C28x45 subgroup without over-provisioning memory or digital resources.

FAQ
What development tools are required to program CY8C28403-24PVXIT?
PSoC Designer™ (free Windows IDE) is the official development environment, providing drag-and-drop user module configuration, automatic API generation, and full-speed emulation. Programming requires MiniProg1 or MiniProg3 hardware debuggers connected via ISSP™ interface - no external programmer is needed for in-system updates.
Does CY8C28403-24PVXIT support true hardware PWM with dead-band generation?
Yes - digital PSoC blocks can be configured as 8- or 16-bit PWMs with programmable dead-band insertion, synchronized start/stop, and kill-input capability. This is implemented in hardware without CPU intervention, ensuring jitter-free motor gate drive timing critical for BLDC and inverter applications.
Can the device operate from a single 3.3 V supply while using its 14-bit ADC?
Yes - the 14-bit SAR ADC operates fully within 3.0–5.25 V supply range. At 3.3 V, it maintains full 14-bit ENOB performance with typical INL of ±1.5 LSB, and internal voltage reference stability is ensured by the integrated precision bandgap circuit.
Is capacitive sensing supported natively without external components?
Yes - the device includes dedicated Type E analog blocks with built-in IDACs and scanning logic for CapSense® functionality. It supports self- and mutual-capacitance measurement on up to 28 GPIOs using only firmware configuration - no external RC networks or dedicated touch controller ICs required.
