Product details
Overview
CY8C4245AZI-483 from Infineon Technologies (formerly Cypress) is a 32-bit Arm Cortex-M0 programmable system-on-chip (PSoC® 4200 family) integrating MCU, reconfigurable analog/digital blocks, 12-bit 1-Msps SAR ADC, two opamps, and two SCBs supporting I²C/SPI/UART. It delivers 48 MHz CPU performance with up to 32 kB flash and 4 kB SRAM, targeting embedded control with capacitive sensing and mixed-signal processing in industrial HMI and motor control interfaces.
For engineers reviewing the CY8C4245AZI-483 datasheet, CY8C4245AZI-483 pinout, CY8C4245AZI-483 application, or CY8C4245AZI-483 equivalent, key selection criteria include its 48-pin TQFP package, –40 °C to +105 °C extended temperature rating, Deep Sleep mode with 20-nA current draw, CapSense Sigma-Delta (CSD) support, and SWD debug interface compatibility with Arm-standard tools.
Technical Context
The device implements a single-layer AHB-Lite interconnect between Cortex-M0 CPU, SRAM, flash with Read Accelerator, and peripheral subsystems. Its analog subsystem includes a CTBm block hosting two opamps (reconfigurable drive modes, comparator operation, ADC input buffering) and a SAR ADC with differential/single-ended sampling, channel sequencer, and signal averaging.
Digital flexibility derives from four Universal Digital Blocks (UDBs), each with 8 macrocells and data path, enabling user-defined state machines or Verilog-based logic. Two serial communication blocks (SCBs) are runtime-reconfigurable as I²C, SPI, or UART, while four TCPWM blocks support center-aligned PWM, kill-signal triggering via comparators, and motor-control timing precision.

IC Role / Device Role / Timing Role: Primary system controller executing CapSense scanning, display driving (LCD), and serial communication with host PLC via UART/I²C. Use Value: Integrated CSD engine and Deep Sleep wakeup reduce BOM count and enable <20 µA standby current while maintaining instant touch responsiveness. | Use Scenario: Compact BLDC motor driver boards needing position feedback processing, PWM generation, and fault monitoring in fan or pump modules. IC Role / Device Role / Timing Role: Real-time motor controller managing hall-sensor inputs, generating center-aligned 3-phase PWM, and triggering emergency shutdown via comparator-based kill signals. Use Value: Four TCPWM blocks with comparator-triggered kill output ensure sub-microsecond fault reaction, meeting IEC 60335 safety timing requirements. |
| Portable Medical Sensors | Energy Monitoring Gateways |
Use Scenario: Battery-powered wearable sensors measuring bio-impedance or temperature, requiring low-power analog acquisition and BLE interface coordination. IC Role / Device Role / Timing Role: Signal acquisition hub digitizing analog sensor outputs via SAR ADC, performing on-chip averaging, and managing BLE SoC communication over UART. Use Value: 20-nA Stop mode with GPIO wakeup extends coin-cell battery life beyond 2 years; integrated opamp buffering avoids external signal conditioning ICs. | Use Scenario: DIN-rail mounted energy meters aggregating current/voltage readings from shunt or CT sensors and reporting via RS-485 or LoRaWAN. IC Role / Device Role / Timing Role: Mixed-signal front-end processor handling 12-bit ADC sampling, RMS calculation, and dual SCB management (RS-485 + LoRaWAN modem UART). Use Value: Single-chip integration of precision ADC, opamp gain stages, and dual configurable serial interfaces reduces component count and improves measurement repeatability across units. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247AZI-M485 | Same PSoC 4200 architecture, but with 64 kB flash, 8 kB SRAM, and additional UDB resources - no change in pinout or peripheral set. | Required when firmware exceeds 32 kB or complex state machines demand more UDB macrocells. | Select for future-proofing firmware growth or advanced digital logic synthesis without PCB redesign. |
| STM32F072CBT6 | Arm Cortex-M0 at 48 MHz, 128 kB flash, 16 kB SRAM, but lacks reconfigurable analog/digital blocks and CapSense hardware acceleration. | Suitable for cost-sensitive applications where fixed-function peripherals suffice and capacitive sensing is implemented externally or via software-based methods. | Choose when analog flexibility is unnecessary and higher memory headroom justifies trade-off in mixed-signal integration. |
Compared with CY8C4245AZI-483, CY8C4247AZI-M485 offers scalable memory and logic resources within identical packaging and thermal specs, while STM32F072CBT6 provides greater flash/SRAM but requires external components for CapSense or programmable analog functions - impacting BOM cost and design cycle time.

FAQ
Does CY8C4245AZI-483 support USB device functionality?
No. The CY8C4245AZI-483 does not include a USB PHY or USB controller. It supports only I²C, SPI, and UART through its two SCB peripherals. For USB connectivity, external bridge ICs (e.g., CP2102N) or migration to PSoC 4100S Plus (with USBFS) is required.
Can the on-chip opamps drive standard LCD segments directly?
Yes. The two opamps can be configured in high-drive external mode to source/sink up to ±25 mA per pin, sufficient for static or multiplexed segment driving. However, dedicated LCD bias generation requires external resistive divider or charge-pump circuits - the opamps serve as segment drivers, not voltage generators.
What debug tools are compatible with CY8C4245AZI-483?
The device supports Arm Serial Wire Debug (SWD) using MiniProg3, KitProg2/3, J-Link, and CMSIS-DAP compliant debuggers. PSoC Creator IDE provides full integration, including flash programming, breakpoints, register view, and real-time variable watch - no JTAG adapter needed due to native 2-wire SWD support.
Is the CapSense functionality certified for IEC 61000-4-3 and IEC 61000-4-6 immunity testing?
Yes. Cypress/Infineon provides CapSense design guides and layout recommendations validated against IEC 61000-4-3 (radiated immunity) and IEC 61000-4-6 (conducted immunity). Reference designs like CY8CKIT-042 achieve Level 3 compliance (10 V/m radiated, 10 V conducted) when following AN88619 and AN79953 layout rules.
