Product details
Overview
CY8C4248BZI-L489 from Infineon is a PSoC™ 4200L programmable system-on-chip featuring a 48 MHz Arm® Cortex®-M0 CPU, 256 kB flash, 32 kB SRAM, four opamps with comparator mode, and dual CAN controllers - deployed in industrial HMI, capacitive touch interfaces, and motor control edge nodes.
For engineers reviewing the CY8C4248BZI-L489 datasheet, CY8C4248BZI-L489 pinout, CY8C4248BZI-L489 application, or CY8C4248BZI-L489 equivalent, key selection criteria include Deep Sleep current (20 nA), CSD-based capacitive sensing SNR (>5:1), USB Full-Speed device support, and dual CAN block integration for deterministic fieldbus communication.
Technical Context
The CY8C4248BZI-L489 implements a tightly coupled mixed-signal architecture where the Arm® Cortex®-M0 core executes firmware while eight Universal Digital Blocks (UDBs) provide hardware-reconfigurable logic for real-time signal processing. Its two CAN 2.0B controllers operate independently with dedicated message RAM and filtering logic.
Analog subsystems include four CTBm opamps supporting simultaneous ADC input buffering and comparator operation, plus two CSD blocks delivering >5:1 SNR for wet-environment touch sensing - all functional in Deep Sleep at ≤1 µA total analog current.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated CSD calibration eliminates manual parameter tuning for varying electrode geometry, overlay thickness, and environmental drift |
| Deep Sleep Analog Operation | Opamps, comparators, and CSD blocks remain active at ≤1 µA total current - enables continuous touch wake-up without CPU intervention |
| Reconfigurable SCBs | Four serial blocks dynamically switch between UART, SPI, and I²C protocols at runtime - reduces BOM count in multi-interface systems |

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 |
|---|---|---|---|
| CY8C4248LQI-BL483 | Same core, 68-pin QFN package; higher GPIO count (94 vs. 48), no USB interface | Better suited for high-pin-count industrial control with CAN + multiple SCBs but no USB device requirement | Select when USB is unnecessary and PCB space permits larger QFN footprint |
| CY8C4247LQI-BL485 | Same 48-pin TQFP package; reduced flash (128 kB) and SRAM (16 kB); retains dual CAN and CSD | Targeted at cost-optimized CAN/CAPSENSE™ nodes where firmware size <128 kB | Select when application firmware fits within 128 kB and budget constraints outweigh memory headroom needs |
Compared with CY8C4248LQI-BL483 and CY8C4247LQI-BL485, the CY8C4248BZI-L489 uniquely balances USB Full-Speed capability, 256 kB flash, and 48-pin TQFP compactness - making it optimal for space-constrained, USB-connected human interface devices requiring field-upgradable firmware.

FAQ
Does CY8C4248BZI-L489 support USB host functionality?
No. The device implements only USB Full-Speed device-mode (12 Mbps) with Battery Charger Detect. It lacks USB host controller hardware, OTG negotiation logic, or VBUS sensing circuitry. Host capability requires external USB PHY or migration to PSoC™ 6 series with dual-role support.
Can the dual CAN controllers operate simultaneously on different bit rates?
Yes. Each CAN block has independent clock dividers, message RAM, and filter units, allowing CAN0 and CAN1 to run at distinct bit rates (e.g., 500 kbps for powertrain and 125 kbps for comfort bus) without resource contention or firmware arbitration.
Is SmartSense™ tuning compatible with custom PCB stack-ups?
Yes. SmartSense™ dynamically adjusts CSD parameters (IDAC current, resolution, scan speed) based on real-time electrode capacitance measurements. It accommodates FR-4, flex, and glass overlays up to 10 mm thick without manual recalibration across production batches.
What debug interface does CY8C4248BZI-L489 use?
The device uses ARM Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins. It supports full JTAG/SWD debugging, flash programming, and real-time trace through MiniProg4 or industry-standard CMSIS-DAP debug probes - no external debug header required.
