Product details
Overview
CY8C5247AXI-051 from Infineon Technologies (acquired Cypress Semiconductor) is a programmable system-on-chip (PSoC® 5) integrating a 32-bit ARM Cortex-M3 CPU, 256 KB flash, 64 KB SRAM, 2 KB EEPROM, 12-bit 700 ksps SAR ADC, and 24 universal digital blocks (UDBs). It operates from 2.7 V to 5.5 V, supports USB 2.0 Full-Speed, CapSense®, and LCD direct drive, and targets embedded control with mixed-signal acquisition in industrial HMI and sensor fusion systems.
For engineers reviewing the CY8C5247AXI-051 datasheet, CY8C5247AXI-051 pinout, CY8C5247AXI-051 application, or CY8C5247AXI-051 equivalent, key selection criteria include its 60 GPIO + 8 SIO + 2 USBIO I/O architecture, configurable analog/digital routing via DSI, low-power hibernate mode (300 nA), and UDB-based peripheral synthesis capability.
Technical Context
The device implements a tightly coupled ARM Cortex-M3 core with 128-byte cache, PHUB-based DMA controller supporting 24 channels and chained descriptors, and nested vectored interrupt controller (NVIC) enabling sub-12-cycle interrupt latency. Its digital subsystem relies on 24 UDBs-each combining PLD logic and state machines-to synthesize peripherals like UART, SPI, I²C, PWM, PRS, and CRC without fixed-function hardware.
Analog signal path flexibility is enabled by a shared analog interconnect bus routing any GPIO to SAR ADC inputs, comparators, DAC outputs, or CapSense® sensors. The 1.024 V ±1% internal reference ensures stable ADC/DAC performance across –40 °C to +85 °C, while dual-domain I/O (VDDIOx) allows mixed-voltage interface operation up to 5.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3, 40 MHz max - enables deterministic real-time control with Thumb-2 instruction set and NVIC for low-latency interrupt handling. |
| Flash Memory | 256 KB, 100K write cycles, 20-year retention - supports field-upgradable firmware and secure bootloader storage. |
| SAR ADC | 12-bit, 700 ksps, ±1 LSB INL - suitable for high-fidelity sensor data acquisition including thermocouples and ultrasonic signals. |
| DAC Output | 8-bit IDAC (5.5 Msps) or VDAC (1 Msps) - provides fast analog stimulus generation routable to any GPIO. |
| Low-Power Modes | Hibernate: 300 nA with RAM retention; Sleep: 2 µA - extends battery life in portable and energy-harvested systems. |
| I/O Count | 60 GPIO + 8 SIO + 2 USBIO - supports multi-channel CapSense® touch, LCD segment driving (46×16), and isolated I²C bus interfacing. |
| Clock Sources | IMO (3–24 MHz), XOSC (4–25 MHz), PLL (up to 40 MHz), 32.768 kHz WCO - enables precise timing for RTC, USB, and synchronous serial protocols. |
Pinout & Package
Package: 68-pin QFN (9 mm × 9 mm, 0.5 mm pitch), RoHS-compliant, exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VDDD | Power supply domains | VDDA powers analog subsystem (2.7–5.5 V); VDDD supplies digital core; separate domains prevent noise coupling into ADC/DAC paths. |
| P0[0]–P0[7], P1[0]–P1[7], etc. | Configurable GPIO/SIO/USBIO | All 60 GPIO support analog muxing, CapSense®, LCD drive, and Schmitt-trigger inputs; SIO pins tolerate overvoltage and provide 25 mA sink for LED control. |
| XTAL_IN/XTAL_OUT | Crytal oscillator interface | Supports 4–25 MHz crystal for precision timing; optional external clock input accepted on XTAL_IN. |
| SWDCK/SWDIO | Serial Wire Debug interface | Enables non-intrusive debugging, flash programming, and real-time trace via SWD/SWV without dedicated debug pins beyond these two. |
| USB_DP/USB_DM | Full-Speed USB 2.0 PHY | Integrated transceiver supports 12 Mbps operation; requires 24 MHz external crystal or PLL-derived clock. |
Key Features
| Feature | Design Value |
|---|---|
| UDB-based peripheral synthesis | 24 programmable logic blocks enable custom digital functions (e.g., quadrature decoder, LIN bus, PRS generator) without FPGA-level complexity. |
| CapSense® on any GPIO | Self- and mutual-capacitance sensing implemented in firmware with no external components - reduces BOM cost and PCB area for touch interfaces. |
| Flexible analog routing | Any GPIO connects to SAR ADC, comparators, or DAC via internal analog bus - eliminates external signal routing and multiplexing ICs. |
| Multi-domain I/O voltage | Four independent VDDIO domains allow simultaneous 1.8 V, 3.3 V, and 5 V interface levels - simplifies mixed-voltage system integration. |
| Secure flash protection | Selective block locking for read/write prevents unauthorized firmware extraction or modification - critical for IP-sensitive industrial firmware. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F411RE | ARM Cortex-M4, 1 MB flash, no integrated analog routing or CapSense®; requires external ADC/DAC for mixed-signal tasks. | Lacks on-chip analog muxing and configurable UDBs - demands additional signal conditioning ICs and PCB routing for sensor interfaces. | Prefer when floating-point math or DSP acceleration is primary requirement and analog integration is handled externally. |
| MAX32660 | ARM Cortex-M4, 256 KB flash, integrated 16-bit ADC but no DAC or UDB-like logic fabric; limited GPIO analog routing. | No programmable digital logic array - cannot synthesize custom peripherals like LIN or PRS without firmware overhead or external logic. | Choose for ultra-low-power wearable designs where analog acquisition dominates and digital flexibility is secondary. |
Compared with STM32F411RE and MAX32660, CY8C5247AXI-051 uniquely combines reconfigurable analog/digital hardware fabric with ARM Cortex-M3 execution - enabling true hardware-software co-design for mixed-signal systems without external component dependencies.

FAQ
What development tools are required to program and debug CY8C5247AXI-051?
PSoC Creator™ IDE is mandatory for schematic-based design, component configuration, and code generation. Programming and debugging require a KitProg or MiniProg3 programmer/debugger connected via SWD interface. No JTAG adapter is needed - SWD uses only SWDCK and SWDIO pins with full trace support through SWV.
Does CY8C5247AXI-051 support USB device enumeration without external components?
Yes - it integrates a full-speed USB 2.0 PHY with internal transceivers and endpoint buffers. Only a 24 MHz crystal (or PLL-synthesized clock) and standard USB connector are required; no external PHY, level shifters, or termination resistors are needed for basic HID or CDC device operation.
Can all 60 GPIO pins be used simultaneously for analog input acquisition?
No - while all 60 GPIO support analog routing, the SAR ADC has a single sample-and-hold circuit and sequential conversion architecture. Maximum concurrent analog inputs depend on multiplexer configuration and scan rate; practical limit is ~24 channels at full 700 ksps throughput due to channel settling and conversion time constraints.
Is the 2 KB EEPROM truly byte-addressable and wear-levelled in hardware?
Yes - the on-chip EEPROM supports true byte-level writes and erases with built-in wear leveling across the entire 2 KB array. Each byte endures 1 million write/erase cycles with guaranteed 20-year data retention at 85 °C, managed autonomously by the PSoC's EEPROM controller without firmware intervention.
