Product details
Overview
CY8C4248BZA-L489 from Infineon is a PSoC™ 4200L automotive-grade 32-bit Arm® Cortex®-M0 microcontroller with 256 kB flash, 32 kB SRAM, dual CAN interfaces, USB Full-Speed device support, and programmable analog/digital blocks. It integrates eight 16-bit TCPWMs, four opamps (Deep Sleep-capable), two low-power comparators, and two capacitive sigma-delta sensing blocks for robust touch interface design in harsh environments.
For engineers reviewing the CY8C4248BZA-L489 datasheet, CY8C4248BZA-L489 pinout, CY8C4248BZA-L489 application, or CY8C4248BZA-L489 equivalent, key selection criteria include automotive-grade operation (–40°C to +125°C), dual-CAN bus support, CAPSENSE™ water-tolerant sigma-delta architecture, and SWD debug compatibility with industry-standard tools.
Technical Context
The device implements an Arm® Cortex®-M0 core running at up to 48 MHz with single-cycle multiply, nested vectored interrupt controller (NVIC), and Wakeup Interrupt Controller (WIC) for Deep Sleep wake-up. Memory subsystem includes 256 kB flash with read accelerator and 32 kB SRAM, both accessible via AHB-Lite interconnect.
Analog resources comprise two CTBm (Capacitive Sigma-Delta) blocks supporting >5:1 SNR and water tolerance, four opamps with Comparator mode and ADC input buffering, and two low-power comparators active in Deep Sleep. Digital flexibility is delivered through eight UDBs (Universal Digital Blocks), each with 8 macrocells and 8-bit data path, plus four reconfigurable SCBs supporting I²C/SPI/UART.

FAQ
Is CY8C4248BZA-L489 qualified for automotive applications?
Yes. It is AEC-Q100 Grade 2 qualified (–40°C to +125°C ambient), features built-in BOD, POR, and LVD circuits, and supports automotive boot ROM with secure flash protection. Its dual CAN controllers and USB Battery Charger Detect align with UNECE R155 compliance requirements for vehicle software updates.
Does this MCU support CAPSENSE™ with water tolerance?
Yes. It integrates two dedicated capacitive sigma-delta (CSD) blocks with hardware SmartSense tuning, achieving >5:1 signal-to-noise ratio and proven water-tolerant operation per Infineon AN85951. No external components are needed for baseline drift compensation.
Can the opamps operate in Deep Sleep mode?
Yes. All four opamps retain full functionality-including comparator mode and ADC input buffering-in Deep Sleep mode with typical current draw below 1 µA per opamp. This enables continuous sensor signal conditioning while main CPU and flash are powered down.
What debug interface does CY8C4248BZA-L489 use?
It uses Arm® Serial Wire Debug (SWD) with two pins (SWDCLK and SWDIO), fully compatible with CMSIS-DAP, J-Link, and Infineon's MiniProg3. Debug circuits are enabled by default and can be permanently disabled in firmware to meet security requirements.
