Overview
CY8C28513-24AXIT 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 and 16 analog PSoC blocks, and configurable GPIOs - designed for embedded control with mixed-signal integration in industrial sensor interfaces and motor control subsystems.
For engineers reviewing the CY8C28513-24AXIT datasheet, CY8C28513-24AXIT pinout, CY8C28513-24AXIT application, or CY8C28513-24AXIT equivalent, key selection criteria include its 24 MHz max CPU speed, ±2.5% internal main oscillator accuracy, 3.0–5.25 V operating voltage range, industrial temperature support (–40 °C to +85 °C), and reconfigurable analog/digital peripheral architecture.
Technical Context
The device implements a fixed-function M8C core with Harvard architecture, supporting 8×8 multiply and 32-bit accumulate operations. Clocking includes a factory-trimmed 24 MHz internal main oscillator (IMO), optional 32.768 kHz crystal input for RTC/PLL-derived clocks, and a low-power internal low-speed oscillator (ILO) for sleep/wake timing.
Analog resources comprise up to 12 rail-to-rail PSoC Blocks delivering ADCs (up to 14-bit, 142 ksps SAR), DACs (up to 9-bit), PGAs, filters, and comparators; plus up to four Type-E blocks for capacitive sensing and 10-bit single-slope ADCs. Digital blocks support UARTs (3 full-duplex, 6 half-duplex), SPI, I²C (2 hardware masters/slaves), PWMs, timers, and CRC/PRS modules.

FAQ
What development tools are required to program CY8C28513-24AXIT?
PSoC Designer™ (free Windows IDE) is the official toolchain, providing drag-and-drop peripheral configuration, automatic API generation, and full-speed emulation via MiniProg1/MiniProg3 programmers. It supports ISSP programming through dedicated pins or I²C interface, and includes device-specific simulation models for analog blocks and timing analysis.
Does CY8C28513-24AXIT support capacitive sensing out of the box?
Yes - it includes four Type-E analog blocks optimized for CapSense® functionality, with built-in hardware support for mutual- and self-capacitance measurement, shield driver outputs, and baseline tracking. Cypress-provided CapSense CSD v2.0 firmware library enables button/slider/gesture detection with <5% false-touch rate under typical EMI conditions.
Can CY8C28513-24AXIT operate below 3.0 V?
Yes - using the on-chip Switched Mode Pump (SMP), it supports operation down to 1.5 V at reduced clock speeds. The SMP boosts internal voltage rails to maintain analog block performance and flash programming integrity, enabling battery-powered designs with alkaline or Li-ion cells without external regulators.
Is there hardware I²C support, and what are its operational limits?
Yes - two independent hardware I²C modules support standard-mode (100 kHz) and fast-mode (400 kHz) operation, with programmable clock stretching, 7- or 10-bit addressing, and multi-master arbitration. Each module handles both master and slave roles simultaneously, with dedicated FIFOs preventing bus lockup during high-traffic sensor polling.
