Infineon Technologies CY8C28413-24PVXIT

Overview

CY8C28413-24PVXIT 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 capacitive sensing, 14-bit SAR ADC (up to 142 ksps), dual I²C, and UART/SPI peripherals for embedded control in industrial HMI and sensor interface applications.

For engineers reviewing the CY8C28413-24PVXIT datasheet, CY8C28413-24PVXIT pinout, CY8C28413-24PVXIT application, or CY8C28413-24PVXIT equivalent, key selection criteria include verified 24 MHz M8C core timing, rail-to-rail analog block configurability, 25 mA GPIO sink capability, and support for in-system serial programming (ISSP™) without external debug hardware.

Technical Context

The device implements a fixed-function M8C core with on-chip 24 MHz ±2.5% internal main oscillator (IMO), complemented by a 32.768 kHz external crystal oscillator (ECO) input for RTC or PLL-based clock synthesis. Its reconfigurable architecture routes signals across global digital and analog interconnects, enabling user-defined peripherals via PSoC Designer™.

Digital resources include up to three full-duplex UARTs, six half-duplex UARTs, multiple SPI masters/slaves (8–16 bit), two I²C controllers (0–400 kHz), and 8–32-bit timers/counters. Analog resources comprise up to four synchronized delta-sigma ADCs, dedicated 14-bit SAR ADC with sample-and-hold, programmable gain amplifiers, and capacitive sensing blocks with dual-channel CSD support.

FAQ

Does CY8C28413-24PVXIT support USB connectivity?

No. The CY8C28413-24PVXIT does not include a USB physical layer or USB protocol engine. It supports UART, SPI, and I²C for host communication. For USB interface, designers must add an external USB-to-UART bridge IC (e.g., CP2102 or FT232RL) connected to its UART pins.

What development tools are required to program this device?

PSoC Designer™ v5.4 or later is required - a free Windows-based IDE that provides drag-and-drop peripheral configuration, automatic API generation, and ISSP™ programming support. Programming hardware includes MiniProg1 or MiniProg3; no JTAG adapter is needed as ISSP uses only two pins (clock and data).

Can this device operate below 3.0 V?

Yes - down to 1.5 V - using the on-chip switched-mode pump (SMP) to boost internal voltage rails. At 1.5 V supply, the M8C core operates at reduced frequency (≤8 MHz), and analog block performance (e.g., ADC resolution, PGA gain) is derated per datasheet Section 3.5.

Is there hardware support for cryptographic functions?

No. The CY8C28413-24PVXIT lacks dedicated crypto accelerators or secure key storage. It supports software-based AES or CRC-16 via M8C assembly/C code, but no hardware TRNG, SHA, or RSA acceleration. For secure boot or key management, external secure elements (e.g., OPTIGA™ Trust) are recommended.
