Product details
Overview
CY8C3244AXI-153 from Infineon Technologies (acquired Cypress Semiconductor) is a PSoC® 3 programmable system-on-chip integrating an 8051 CPU core, configurable analog/digital peripherals, 32 KB flash, 2 KB RAM, and 2 KB EEPROM in a 48-pin SSOP package. It operates from 1.71–5.5 V at up to 50 MHz, features Delta-Sigma ADC (12-bit), dual comparators, CapSense® support for 62 sensors, and USB 2.0 FS interface - used in industrial HMI, medical sensor hubs, and battery-powered touch interfaces.
For engineers reviewing the CY8C3244AXI-153 datasheet, CY8C3244AXI-153 pinout, CY8C3244AXI-153 application, or CY8C3244AXI-153 equivalent, key selection criteria include its 48-SSOP footprint, 29 GPIOs with SIO/USBIO capability, integrated 50 MHz PLL, 200 nA hibernate mode with RAM retention, and full PSoC Creator™ toolchain compatibility for mixed-signal firmware-hardware co-design.
Technical Context
The CY8C3244AXI-153 implements a single-cycle 8051 CPU core with 32 interrupt inputs and 24-channel DMA controller, enabling real-time peripheral data movement without CPU intervention. Its digital subsystem uses 16 Universal Digital Blocks (UDBs) to implement configurable logic including UART, SPI, I²C, PWM, CRC, and PRS - all routable to any GPIO via the Digital System Interconnect (DSI).
Analog resources include a 12-bit Delta-Sigma ADC (±1 LSB INL, 66 dB SINAD), 8-bit DAC (1 MSPS VDAC / 8 MSPS IDAC), two rail-to-rail comparators, and a 1.024 V ±1% internal reference. All analog signals are routed through a dedicated analog bus supporting CapSense® electrode scanning and LCD segment driving (up to 46×16).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Single-cycle 8051 running up to 50 MHz - enables deterministic real-time control with sub-μs interrupt latency. |
| Flash / RAM / EEPROM | 32 KB flash (with ECC support), 2 KB SRAM, 2 KB EEPROM - sufficient for bootloader + application + persistent calibration data. |
| ADC Resolution & Accuracy | 12-bit Delta-Sigma ADC with ±1 LSB INL/DNL and 66 dB SINAD - meets precision sensor signal chain requirements (e.g., thermistor, strain gauge). |
| CapSense® Channels | Supports up to 62 self- or mutual-capacitance sensors - enables full-touch HMI panels without external controllers. |
| USB Interface | Full-Speed USB 2.0 (12 Mbps) with on-die PHY - eliminates need for external transceiver in HID or CDC device designs. |
| Low-Power Modes | 200 nA hibernate (RAM retained), 1 µA sleep (RTC active) - extends battery life in coin-cell or energy-harvesting applications. |
| I/O Flexibility | 29 GPIOs + 4 SIOs + 2 USBIOs; all support analog routing, LCD drive, and CapSense - reduces BOM count and PCB layer count. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDA / VSSA | Analog power supply / ground | Isolates noise-sensitive analog circuits (ADC, comparators); requires separate filtering from digital rails. |
| VDDD / VSSD | Digital core power / ground | Powers CPU, flash, RAM, and digital logic; must be decoupled near VDDD pin with 100 nF ceramic capacitor. |
| VDDIO0–VDDIO3 | I/O voltage domain supplies | Enable independent 1.8/2.5/3.3/5.0 V I/O levels per group - supports mixed-voltage interfacing without level shifters. |
| P0[0]–P2[7] | Configurable GPIOs | All support digital input/output, analog input, CapSense®, LCD segment/com, and interrupt generation - fully software-routed. |
| P15[6]/P15[7] | USBIO D+/D− | Dedicated full-speed USB physical layer pins; internally terminate 1.5 kΩ pull-up on D+ for device enumeration. |
| P1[3]/P1[2] | SWDIO/SWDCK | 2-wire Serial Wire Debug interface - enables programming and real-time debugging using MiniProg3 or third-party SWD probes. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Analog Subsystem | On-chip 12-bit Delta-Sigma ADC, 8-bit DAC, dual comparators, and 1.024 V reference - eliminates discrete signal conditioning ICs in sensor nodes. |
| UDB-Based Digital Logic | 16 Universal Digital Blocks enable hardware implementation of custom protocols (e.g., proprietary sensor bus) or accelerators (e.g., CRC-16 engine) without CPU load. |
| CapSense® Integration | Hardware-accelerated capacitive sensing engine supporting proximity, slider, and gesture detection - reduces firmware overhead and improves SNR vs. software-only solutions. |
| Flexible Clock Architecture | Internal IMO (3–24 MHz), PLL (up to 50 MHz), ILO (1/33/100 kHz), and external crystal support - allows dynamic clock scaling for power/performance trade-offs. |
| Multi-Voltage I/O Domains | Four independent VDDIO supplies (VDDIO0–VDDIO3) - permits direct interfacing with 1.8 V logic, 3.3 V sensors, and 5 V actuators on same die. |

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 |
|---|---|---|---|
| CY8C3245AXI-153 | Same package and pinout; 64 KB flash, 8 KB RAM, 2 KB EEPROM - doubles memory capacity. | Required for complex USB CDC + BLE coexistence firmware or large CapSense® gesture libraries. | Select when >32 KB flash is needed for field-upgradable firmware or multi-protocol stacks. |
| CY8C4045AZI-S412 | PSoC 4 (ARM Cortex-M0+), 32 KB flash, 4 KB RAM, no USB FS PHY - lacks native USB but adds BLE radio. | Suitable for wireless sensor endpoints where USB is replaced by BLE OTA updates and local touch UI. | Choose for Bluetooth-connected devices needing RF certification; avoid if USB HID/CDC is mandatory. |
Compared with CY8C3244AXI-153, CY8C3245AXI-153 offers scalable memory for future firmware growth, while CY8C4045AZI-S412 trades USB for integrated BLE - making the former ideal for wired industrial UIs and the latter for wireless edge nodes.

FAQ
What development tools are required to program CY8C3244AXI-153?
The official PSoC Creator™ IDE (free download from Infineon) is mandatory for hardware configuration and firmware development. Programming requires MiniProg3 or KitProg debugger via SWD interface. USB-based bootloader is supported but requires initial flash programming via SWD to enable.
Does CY8C3244AXI-153 support hardware encryption or secure boot?
No. CY8C3244AXI-153 does not include hardware AES engines, secure boot ROM, or cryptographic key storage. Flash protection is limited to row-level read/write lock bits; sensitive firmware must rely on external secure elements or obfuscated software techniques.
Can the internal 12-bit ADC measure signals beyond the supply rail?
No. The Delta-Sigma ADC accepts only single-ended or differential inputs within the VSSA–VDDA range. Input signals exceeding VDDA require external level-shifting or attenuation circuitry; the internal programmable gain amplifier (PGA) supports only gains of 1–48× within rail-to-rail limits.
Is the USB interface certified for full-speed operation?
Yes. CY8C3244AXI-153's USB 2.0 FS peripheral is TID#40770053 certified per USB-IF standards. It supports HID, CDC, and MSC class drivers using the on-die PHY and internal 48 MHz PLL clock - no external crystal required for USB timing.
