Product details
Overview
CY8C4247BZI-L489 from Infineon is a PSoC™ 4200L-series 32-bit Arm® Cortex®-M0 microcontroller with 256 kB flash, 32 kB SRAM, four opamps supporting comparator mode and Deep Sleep operation, two CAN controllers, and USB Full-Speed device interface. It integrates programmable analog (CSD capacitive sensing, SAR ADC), digital logic (UDBs), and timing peripherals (TCPWM) for embedded control in industrial HMI and automotive body electronics.
For engineers reviewing the CY8C4247BZI-L489 datasheet, CY8C4247BZI-L489 pinout, CY8C4247BZI-L489 application, or CY8C4247BZI-L489 equivalent, key selection criteria include its dual-CAN capability, 94 GPIO with CAPSENSE™ support, 48 MHz CPU clock, Deep Sleep current down to 20 nA, and VFBGA-124 package compatibility with high-density PCB layouts.
Technical Context
The device implements an Arm® Cortex®-M0 core with single-cycle multiply and a tightly coupled memory subsystem including Read Accelerator for deterministic flash execution. Its analog subsystem includes two independent CSD blocks with >5:1 SNR and SmartSense™ auto-tuning, plus four CTBm opamps configurable as buffers, comparators, or transimpedance amplifiers.
Digital flexibility derives from eight Universal Digital Blocks (UDBs), each with 8 macrocells and 8-bit datapath, enabling custom state machines or peripheral extensions. Four SCBs support runtime-reconfigurable I²C/SPI/UART, while two dedicated CAN 2.0B controllers operate independently with message RAM and filtering-critical for distributed vehicle networks.

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 |
|---|---|---|---|
| CY8C4248LQI-BL483 | Same PSoC™ 4200L family; 128-ball QFN package, 192 kB flash, no USB interface | Lacks USB FS PHY and Battery Charger Detect - unsuitable for direct USB-connected devices | Select when board space constraints favor QFN and USB is not required |
| STM32G474RET6 | Arm® Cortex®-M4F @ 170 MHz, 512 kB flash, no integrated capacitive sensing or programmable analog fabric | Requires external components for touch sensing and analog signal conditioning; higher compute throughput but less analog integration | Select when floating-point math or motor control algorithms dominate over mixed-signal flexibility |
Compared with CY8C4247BZI-L489, CY8C4248LQI-BL483 trades USB and package size for smaller footprint and lower cost, while STM32G474RET6 offers higher CPU performance but demands external analog circuitry and lacks hardware-accelerated CSD - making it less optimal for touch-centric, low-power embedded designs.

FAQ
What development tools are supported for CY8C4247BZI-L489?
PSoC™ Creator IDE is the primary development environment, offering schematic-based hardware design, automatic routing, and pre-verified component libraries. Firmware can also be developed using Arm®-compliant GCC toolchains or Keil MDK after initial configuration export. Debugging requires MiniProg4 or KitProg3 programmers compatible with SWD interface.
Does CY8C4247BZI-L489 support secure boot or cryptographic acceleration?
No. CY8C4247BZI-L489 does not include hardware cryptographic accelerators or secure boot ROM. It relies on software-implemented authentication and flash protection mechanisms. For secure boot requirements, Infineon's PSoC™ 6 series (e.g., CY8C6247FDI-D52) provides dedicated ARM TrustZone® and hardware AES engines.
Can the opamps in CY8C4247BZI-L489 drive external loads directly?
Yes - each CTBm opamp supports programmable output drive strength up to 25 mA sink/source and rail-to-rail output swing. They can directly drive LEDs, small relays, or ADC reference buffers, but require external compensation for capacitive loads >100 pF to ensure stability.
Is the CAN interface compliant with ISO 11898-2 physical layer standards?
No - CY8C4247BZI-L489 implements only the CAN protocol controller (ISO 11898-1). A separate CAN transceiver (e.g., TJA1042T/3) is required for physical layer compliance, ESD protection, and bus termination. The device provides differential TX/RX signals compatible with standard high-speed transceivers.
