Overview
CY8C28403-24PVXI from Infineon Technologies (formerly Cypress Semiconductor) is a programmable System-on-Chip (PSoC® 1) integrating an M8C 8-bit Harvard-architecture microcontroller, configurable analog and digital blocks, and 16 KB flash/1 KB SRAM. It operates at up to 24 MHz with 3.0–5.25 V supply, supports rail-to-rail analog peripherals including 14-bit SAR ADC (142 ksps), and targets embedded control applications requiring mixed-signal integration in industrial and consumer systems.
For engineers reviewing the CY8C28403-24PVXI datasheet, CY8C28403-24PVXI pinout, CY8C28403-24PVXI application, or CY8C28403-24PVXI equivalent, key selection criteria include its 24 MHz M8C core speed, 14-bit SAR ADC performance, 25 mA GPIO sink capability, programmable clocking (IMO ±2.5%, ECO support), and PSoC Designer™-based reconfigurable peripheral architecture.
Technical Context
The CY8C28403-24PVXI implements a fixed-function M8C CPU core with Harvard architecture, supporting 8×8 multiply and 32-bit accumulate operations. Its digital system comprises up to 12 programmable 8-bit digital blocks that can be combined into timers, PWMs, UARTs (up to 3 full-duplex), SPI, I²C, and CRC modules - all routable to any GPIO via global interconnect.
The analog system includes up to 12 rail-to-rail PSoC Blocks delivering configurable ADCs (SAR up to 142 ksps, delta-sigma), DACs (up to 9-bit), PGAs, filters, and comparators. It also integrates dual hardware I²C resources (0–400 kHz), on-chip switched-mode pump (SMP) enabling operation down to 1.5 V, and precision internal voltage references.

FAQ
What development tools are required to program the CY8C28403-24PVXI?
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-circuit flashing.
Does the CY8C28403-24PVXI support true hardware PWM with dead-band generation?
Yes - its digital PSoC blocks support 8- and 16-bit PWM with configurable dead-band insertion and kill input, implemented in dedicated hardware without CPU overhead. This enables robust gate-drive signal generation for half-bridge and H-bridge motor drivers.
Can the internal 24 MHz oscillator meet timing requirements for UART communication at 115.2 kbps?
Yes - the internal main oscillator (IMO) has ±2.5% accuracy over voltage and temperature, which is sufficient for UART operation up to 115.2 kbps with standard 16x oversampling. For higher baud rates or tighter tolerance, the 32.768 kHz ECO with PLL-derived clock is recommended.
Is EEPROM emulation supported, and how is it implemented?
Yes - the device supports EEPROM emulation in flash memory using Cypress's Emulated EEPROM User Module. It leverages wear-leveling across designated flash sectors and provides byte-addressable read/write access with 50,000+ endurance cycles, managed transparently by firmware libraries.
