Product details
Overview
CY8C4248AZI-L485 from Infineon is a 32-bit Arm® Cortex®-M0 microcontroller in the PSoC™ 4200L family, integrating programmable analog (4 opamps, 2 comparators, 12-bit SAR ADC), digital (8 UDBs, 4 SCBs, 8 TCPWM), and capacitive sensing (2 CSD blocks) subsystems. It operates from 1.71 V to 5.5 V, supports Deep Sleep at 20 nA, and delivers up to 48 MHz CPU performance with 256 kB flash and 32 kB SRAM - deployed in industrial HMI touch panels requiring robust water-tolerant CAPSENSE™.
For engineers reviewing the CY8C4248AZI-L485 datasheet, CY8C4248AZI-L485 pinout, CY8C4248AZI-L485 application, or CY8C4248AZI-L485 equivalent, key selection criteria include its dual CAN interface, on-die SmartSense™ auto-tuning for capacitive sensors, USB Full-Speed device capability, and 48-pin TQFP package with 38 GPIOs supporting configurable drive strength and slew rate.
Technical Context
The device implements an Arm® Cortex®-M0 core with single-cycle multiply and a tightly coupled memory subsystem including 256 kB flash (with Read Accelerator), 32 kB SRAM, and 8 kB SROM. Its clock system integrates IMO (internal main oscillator), ILO (internal low-speed oscillator), and support for external crystals with PLL for precise timing control.
Analog resources include four CTBm opamp blocks (each configurable as opamp, comparator, or transimpedance amplifier), two independent low-power comparators, and a 12-bit SAR ADC with up to 1 Msps sampling rate and programmable input buffering - all accessible via flexible analog multiplex bus routing to any GPIO.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0, 48 MHz max - enables deterministic real-time control with <100 ns interrupt latency. |
| Flash / SRAM | 256 kB flash with Read Accelerator + 32 kB SRAM - supports complex firmware with bootloader, stack, and data buffers. |
| Analog Peripherals | 4 opamps (Deep Sleep capable), 2 comparators, 12-bit SAR ADC (1 Msps), 2 CSD blocks - enables integrated sensor signal conditioning and touch sensing without external ICs. |
| Digital Peripherals | 8 UDBs (8 macrocells each), 4 SCBs (reconfigurable I²C/SPI/UART), 2 CAN 2.0B controllers, 8 TCPWM - allows custom logic, multi-protocol comms, and motor control PWM generation. |
| Power & Packaging | 1.71–5.5 V operation, 20 nA Stop Mode, 48-pin TQFP (7×7 mm) - suitable for battery-powered and industrial environments with wide supply tolerance. |
| GPIO | 38 programmable pins with configurable drive modes (strong, open-drain, high-Z), slew rate, and pull-up/down - simplifies PCB layout and reduces external level-shifting components. |
Pinout & Package
48-pin TQFP (7×7 mm, 0.5 mm pitch), RoHS-compliant, thermally enhanced for industrial ambient operation up to +85 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual-supply domain: VDD powers digital/analog core; VSS is common reference - requires local 100 nF decoupling per supply pair. |
| P0[0]–P0[7], P1[0]–P1[7], P2[0]–P2[7], P3[0]–P3[7], P4[0]–P4[5] | Programmable GPIO | 38 total pins support CAPSENSE™, analog input/output, digital logic, or serial interface - each independently configurable for drive strength and interrupt capability. |
| XRES | External reset input | Active-low asynchronous reset with internal pull-up - accepts 1.8–5.5 V logic levels; debounced internally for noise immunity. |
| USB_DP / USB_DM | USB 2.0 Full-Speed differential pair | Integrated transceiver with Battery Charger Detect (BCD) - eliminates need for external USB PHY in charging-aware embedded devices. |
| CAN0_TX / CAN0_RX / CAN1_TX / CAN1_RX | Dual CAN 2.0B physical interface | Two independent CAN controllers with dedicated TX/RX pins - supports redundant networking or separate chassis/control bus domains. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated CSD calibration adjusts baseline, sensitivity, and noise thresholds dynamically - eliminates manual tuning across temperature/humidity variations. |
| Deep Sleep Analog Operation | Opamps and comparators remain active in Deep Sleep mode at sub-μA current - enables always-on capacitive wake detection without MCU core power-up. |
| Reconfigurable SCBs | Four serial communication blocks each support runtime-switchable I²C/SPI/UART protocols - reduces BOM count and simplifies firmware updates for multi-interface field deployments. |
| UDB-Based Custom Logic | Eight universal digital blocks provide Verilog-synthesizable logic with 8-bit datapath and state machine support - implements glue logic, protocol accelerators, or safety monitors without FPGA. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LTI-L485 | Same PSoC™ 4200L core but in 68-pin QFN; adds 10 more GPIOs and 2 additional SCBs. | Better suited for designs requiring >38 I/O or triple-protocol serial expansion (e.g., simultaneous CAN + USB + SPI). | Select when pin count and peripheral concurrency exceed CY8C4248AZI-L485's 48-pin TQFP limits. |
| CY8C4248LQI-L485 | Identical feature set and pinout, but in 124-ball VFBGA package with higher I/O density (94 GPIOs) and improved thermal dissipation. | Targeted at space-constrained, high-reliability applications (e.g., medical PCBs) where TQFP rework is impractical. | Choose for miniaturized layouts needing maximum I/O in smallest footprint, accepting BGA assembly complexity. |

FAQ
Does CY8C4248AZI-L485 support USB device functionality without external PHY?
Yes. It integrates a full-speed USB 2.0 device controller with on-die transceiver, supporting 12 Mbps operation and Battery Charger Detect (BCD) compliance. No external PHY or level-shifting components are required - USB_DP and USB_DM connect directly to the USB connector with appropriate ESD protection.
What is the maximum operating temperature and qualification standard for this part?
CY8C4248AZI-L485 is rated for industrial temperature range: –40 °C to +85 °C ambient. It is qualified per AEC-Q100 Grade 3 standards for reliability and stress testing, including HTOL, ESD, and latch-up immunity - making it suitable for under-hood automotive and factory-floor industrial use.
Can the opamps operate while the CPU is in Deep Sleep mode?
Yes. All four CTBm opamps and both low-power comparators retain full functionality in Deep Sleep mode with typical current draw of 1.2 μA per opamp. They can generate interrupts or trigger TCPWM kill signals autonomously - enabling continuous sensor monitoring without waking the Cortex®-M0 core.
Is PSoC™ Creator IDE still supported for this device?
Yes. Infineon continues to support PSoC™ Creator v4.4 for CY8C4248AZI-L485 development, including schematic-based design entry, automatic analog/digital routing, and pre-verified component libraries. While ModusToolbox™ is now Infineon's strategic IDE, Creator remains fully functional and maintained for legacy PSoC™ 4 projects.
