Infineon Technologies CY8C4148LDES553XQLA1

Overview

CY8C4148LDES553XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade PSoC™ 4100S Max microcontroller based on Arm® Cortex®-M0+ CPU running at 48 MHz, featuring 384 KB flash, 32 KB SRAM, CAN FD up to 5 Mbps, 12-bit 1-Msps SAR ADC, and integrated CAPSENSE™ MSC block with >5:1 SNR for capacitive touch. It targets body control modules and in-cabin human-machine interface systems requiring functional safety-aware programmable analog/digital resources.

For engineers reviewing the CY8C4148LDES553XQLA1 datasheet, CY8C4148LDES553XQLA1 pinout, CY8C4148LDES553XQLA1 application, or CY8C4148LDES553XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep current (2.5 µA), GPIO reconfigurability across analog/digital/CAPSENSE™ domains, and hardware cryptographic acceleration (AES/SHA/TRNG) for secure boot and firmware updates.

Technical Context

The device integrates a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 5 reconfigurable Serial Communication Blocks (SCBs), and 8 TCPWM blocks supporting quadrature decoding and comparator-triggered kill signals-enabling motor control and safety-critical timing functions. Its analog subsystem includes two opamps operable in Deep Sleep mode, a temperature-sensing SAR ADC, and dual low-power comparators.

The CAPSENSE™ Multi-Sense Converter (MSC) block delivers hardware-accelerated capacitive sensing with SmartSense auto-tuning and water-tolerant operation, while the CAN FD controller supports ISO 11898-1:2015 compliant data rates up to 5 Mbps with flexible message filtering and error handling.

FAQ

What is the maximum operating temperature range for CY8C4148LDES553XQLA1?

This part is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. The specification is validated across full voltage range (1.71 V to 5.5 V) and includes thermal derating curves for flash programming and analog performance stability per datasheet Section 7.2.1.

Does CY8C4148LDES553XQLA1 support CAN FD with ISO 11898-1:2015 compliance?

Yes. The integrated CAN FD controller supports data rates up to 5 Mbps, ISO 11898-1:2015 frame formatting, flexible message filtering, and error confinement. Hardware FIFOs and interrupt-driven status registers enable deterministic real-time handling without CPU polling overhead.

Can all 84 GPIO pins be used simultaneously for CAPSENSE™ sensing?

No. While any GPIO pin can be configured for CAPSENSE™, the MSC block supports up to 32 simultaneous sensing channels. Channel allocation is managed by the CAPSENSE™ Component in ModusToolbox™, with hardware resource arbitration ensuring no conflict between analog, digital, and CAPSENSE™ functions.

Is hardware cryptographic acceleration available in Deep Sleep mode?

No. The Crypto block (AES/SHA/TRNG/CRC) requires Active or Sleep mode operation. However, TRNG entropy generation can be initiated before entering Deep Sleep, and keys may be retained in protected SRAM regions with power-gating isolation to maintain security context across low-power transitions.
