Product details
Overview
CY8C28513-24AXI 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 reconfigurable analog/digital blocks. 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 14-bit SAR ADC (142 ksps) for embedded control in industrial sensor interfaces.
For engineers reviewing the CY8C28513-24AXI datasheet, CY8C28513-24AXI pinout, CY8C28513-24AXI application, or CY8C28513-24AXI equivalent, key selection criteria include its 24 MHz M8C core speed, 16 KB flash endurance (50,000 cycles), configurable GPIO drive modes (25 mA sink), on-chip switched-mode pump for 1.5 V operation, and support for capacitive sensing via Type E analog blocks.
Technical Context
The CY8C28513-24AXI implements a fixed-function M8C core with Harvard architecture, internal ±2.5% 24 MHz IMO clock, and optional 32.768 kHz ECO for RTC. Its digital system uses up to 12 programmable 8-bit digital blocks combinable into timers, PWMs, UARTs, SPI, and CRC modules - all routable to any GPIO via global interconnect.
Analog functionality includes up to 12 Type A blocks supporting 14-bit SAR ADC (with sample-and-hold), 9-bit DAC, PGA, and programmable filters, plus up to four Type E blocks enabling capacitive sensing, comparator-based threshold detection, and 10-bit single-slope ADC - all sharing analog input capability across all GPIOs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | M8C 8-bit Harvard architecture, 24 MHz max - enables deterministic real-time control with 4 MIPS throughput |

Pinout & Package
CY8C28513-24AXI is housed in a 44-pin TQFP package (10 mm × 10 mm, 0.8 mm pitch) with exposed thermal pad. Pin assignments follow standard PSoC 1 44-pin layout, supporting six I/O ports (Port 0–Port 5), dedicated reset, VDD/VSS, crystal inputs (XIN/XOUT), and SWD debug interface pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Primary power domain; requires local 100 nF decoupling per VDD pin |
| XIN, XOUT | 32.768 kHz crystal oscillator terminals | Supports precise RTC timing; internal load caps eliminate external components |
| P0[0]–P5[7] | Configurable GPIO | All pins support analog input, interrupt-on-change, and 8 drive modes including open-drain |
| SWDIO, SWCLK | Serial Wire Debug interface | Enables in-circuit programming and full-speed emulation using MiniProg3 |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; compatible with pushbutton or supervisor IC assertion |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C28443-24AXI | Same M8C core and package, but 8 KB flash and no Type E analog blocks | Lacks capacitive sensing capability; limited to simpler analog tasks | Select when CapSense® or high-resolution ADC is not required and cost optimization is critical |
| CY8C29466-24AXI | 24 MHz M8C core, 32 KB flash, 2 KB SRAM, adds USB 1.1 interface | Includes full-speed USB PHY and transceiver - adds host/device connectivity | Choose when USB communication or larger code footprint is needed; requires additional USB layout considerations |
Compared with CY8C28443-24AXI, the CY8C28513-24AXI provides double flash capacity and capacitive sensing support; versus CY8C29466-24AXI, it trades USB capability for lower cost and reduced layout complexity in isolated embedded control roles.

FAQ
What development tools are required to program CY8C28513-24AXI?
PSoC Designer™ (free Windows IDE) is the official toolchain, supporting drag-and-drop peripheral configuration, automatic API generation, and full-speed emulation. Programming requires MiniProg1 or MiniProg3 hardware debuggers connected via SWD interface. No third-party toolchains are officially supported.
Does CY8C28513-24AXI support capacitive sensing out of the box?
Yes - it includes four Type E analog blocks specifically designed for CapSense®. These provide hardware-accelerated baseline tracking, noise filtering, and shield driver outputs. Cypress-provided CapSense_CSD user module in PSoC Designer configures these blocks without custom firmware.
Can CY8C28513-24AXI operate below 3.0 V?
Yes - using the on-chip switched-mode pump (SMP), it supports core operation down to 1.5 V while maintaining full functionality, including ADC and CPU execution. This mode requires enabling the SMP in system configuration and accepting higher quiescent current.
Is there hardware I²C support, and what are its limitations?
CY8C28513-24AXI includes two dedicated hardware I²C resources supporting slave, master, and multi-master modes at up to 400 kHz. Each resource has independent address registers and interrupt flags, but shares the same SCL/SDA pins - simultaneous dual-bus operation is not supported without external multiplexing.
