Infineon Technologies CY8C28413-24PVXI

Overview

CY8C28413-24PVXI from Infineon Technologies (formerly Cypress Semiconductor) is a programmable System-on-Chip (PSoC® 1) featuring an M8C 8-bit Harvard architecture CPU running at up to 24 MHz, 16 KB flash, 1 KB SRAM, and configurable analog/digital blocks for mixed-signal embedded control. It operates from 3.0 V to 5.25 V across –40 °C to +85 °C and integrates dual I²C, up to three UARTs, and rail-to-rail analog resources including SAR ADCs (up to 142 ksps) - deployed in industrial sensor nodes and motor control interfaces.

For engineers reviewing the CY8C28413-24PVXI datasheet, CY8C28413-24PVXI pinout, CY8C28413-24PVXI application, or CY8C28413-24PVXI equivalent, key selection criteria include its 24 MHz M8C core speed, 16 KB flash endurance (50,000 erase/write cycles), 25 mA GPIO sink capability, integrated switched-mode pump for 1.5 V operation, and support for capacitive sensing via dedicated analog blocks.

Technical Context

This PSoC 1 device implements a fixed-function M8C core with on-chip IMO (±2.5% accuracy at 24/48 MHz), ILO (32 kHz), and optional ECO (32.768 kHz) for RTC or PLL-based clock synthesis. Its digital system uses up to 12 reconfigurable 8-bit blocks to construct timers, PWMs, UARTs, SPI, and CRC modules routed via global interconnects to any GPIO.

The analog subsystem includes up to 12 Type-2 (rail-to-rail) and four Type-E (capacitive sensing) blocks, enabling simultaneous high-resolution SAR ADC conversion (14-bit, sample-and-hold), programmable gain amplification, comparator-based threshold detection, and delta-sigma ADC synchronization - all configurable without external components.

FAQ

What development tools are required to program CY8C28413-24PVXI?

PSoC Designer™ (free Windows IDE) is the official development environment, supporting drag-and-drop peripheral configuration, automatic API generation, and full-speed emulation. Programming requires MiniProg1 or MiniProg3 via SWD/ISSP interface. No third-party toolchains are supported - all compilation, debugging, and flash operations are handled exclusively within PSoC Designer.

Does CY8C28413-24PVXI support capacitive touch sensing?

Yes - it includes four dedicated Type-E analog blocks optimized for CapSense® functionality, enabling robust self- and mutual-capacitance sensing with built-in IDACs, shield drivers, and noise filtering. These blocks operate independently of the M8C core and support automatic baseline calibration and low-power wake-on-touch modes.

Can CY8C28413-24PVXI operate below 3.0 V?

Yes - using the on-chip switched-mode pump (SMP), it can operate down to 1.5 V from a single supply. The SMP generates an internal regulated 1.5 V rail that powers the analog and digital subsystems, enabling extended battery life in portable applications without external DC-DC converters.

Is the 24 MHz internal oscillator accurate enough for UART communication?

Yes - the ±2.5% tolerance of the 24 MHz IMO is sufficient for standard UART baud rates (e.g., 9600, 19200, 115200) when using oversampling and error-correcting framing. For higher-precision serial links (e.g., USB CDC or synchronous protocols), the optional 32.768 kHz ECO with PLL is recommended to generate a stable 24 MHz clock with <0.1% drift.
