Product details

Overview

CY8C4148AZSS588XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 384 KB flash, 32 KB SRAM, integrated CAN FD (up to 5 Mbps), and multi-sense capacitive sensing (MSC) with >5:1 SNR for touch interfaces in harsh environments.

For engineers reviewing the CY8C4148AZSS588XQLA1 datasheet, CY8C4148AZSS588XQLA1 pinout, CY8C4148AZSS588XQLA1 application, or CY8C4148AZSS588XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep current (2.5 µA), CAPSENSE™ water tolerance, and reconfigurable SCB blocks supporting I²C/SPI/UART/LIN in automotive body control modules.

Technical Context

The device implements a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 5x Serial Communication Blocks (SCBs), and CAN FD controller with dedicated DMA channels. Its analog subsystem integrates two opamps with Deep Sleep operation, a 12-bit 1-Msps SAR ADC with temperature sensor, and dual low-power comparators - all accessible via up to 84 GPIOs with programmable drive strength and slew rate.

Digital flexibility is enabled by 8x TCPWM blocks supporting center-aligned PWM and quadrature decoding, Smart I/O for Boolean logic on port signals, and hardware-accelerated cryptography (AES, SHA, TRNG, CRC). Clocking includes ECO (4–33 MHz) with PLL, WCO (32 kHz), IMO (±2%), and ILO (40 kHz).

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive microcontroller applications.

Alternative PartTechnical DifferenceApplication DifferenceSelection Advice
NXP S32K144HAT0MLHTARM Cortex-M4F @ 112 MHz; 512 KB flash; no integrated CAPSENSE™; supports CAN FD but lacks MSC block.Better floating-point performance for motor control algorithms; requires external touch controller for capacitive HMI.Select when real-time motor control dominates over touch interface integration.
Renesas RL78/F14RL78 core @ 32 MHz; 256 KB flash; CAN FD support only via external transceiver; no hardware crypto acceleration.Lower cost for basic body control; lacks Deep Sleep analog retention and MSC SNR performance.Select for cost-sensitive entry-level BCMs where touch is not required and security is handled externally.

Compared with S32K144HAT0MLHT and RL78/F14, CY8C4148AZSS588XQLA1 uniquely combines CAN FD, CAPSENSE™ MSC, and hardware crypto in a single AEC-Q100 Grade-S package - making it optimal for integrated HMI + gateway applications where BOM consolidation and environmental robustness are critical.

FAQ

Does CY8C4148AZSS588XQLA1 support CAN FD physical layer directly?

No - it integrates a CAN FD controller but requires an external CAN FD transceiver (e.g., Infineon TLE9251VS) for physical layer signaling. The controller handles protocol framing, bit timing, error handling, and message filtering, while the transceiver manages differential voltage levels and bus arbitration.

What is the maximum operating frequency of the internal main oscillator (IMO)?

The internal main oscillator (IMO) operates at a nominal 48 MHz with ±2% accuracy across temperature and voltage. It serves as the default clock source for the Cortex-M0+ core and can be used without external crystals, though ECO+PLL is recommended for CAN FD bit timing compliance.

Can all 84 GPIOs be used simultaneously for CAPSENSE™ sensing?

No - while any GPIO can be assigned to CAPSENSE™, the Multi-Sense Converter (MSC) block supports up to 32 simultaneous sensing channels. Concurrent use of all 84 pins for sensing would require time-multiplexing across multiple scan cycles, increasing total measurement latency.

Is the 32 KB SRAM ECC-protected?

No - the 32 KB SRAM does not include hardware ECC protection. However, the device supports software-implemented ECC or parity checking via PDL APIs, and critical data structures can be allocated to the 8 KB ROM or flash with checksum validation for safety-critical applications.
