Product details
Overview
CY8C4148LDAS543XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller based on a 48-MHz Arm® Cortex®-M0+ CPU, featuring 384 KB flash, 32 KB SRAM, CAN FD up to 5 Mbps, 12-bit 1-Msps SAR ADC, and integrated CAPSENSE™ with SmartSense auto-tuning. It targets body control modules, smart sensors, and automotive HMI systems requiring robust capacitive touch in harsh environments.
For engineers reviewing the CY8C4148LDAS543XQLA1 datasheet, CY8C4148LDAS543XQLA1 pinout, CY8C4148LDAS543XQLA1 application, or CY8C4148LDAS543XQLA1 equivalent, key selection considerations include CAN FD timing compliance, Deep Sleep current (2.5 µA), MSC SNR (>5:1), programmable analog routing, and GPIO flexibility across 84 pins in 100-pin TQFP.
Technical Context
The device integrates a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 5 reconfigurable Serial Communication Blocks (SCBs), and dedicated CAN FD controller with bit-rate switching support up to 5 Mbps. Its analog subsystem includes two CTBm opamps with Deep Sleep operation, dual low-power comparators, and a temperature-sensor-integrated SAR ADC with hardware averaging and sequencer.
Digital flexibility is enabled by eight TCPWM blocks supporting center-aligned PWM and quadrature decoding, Smart I/O for Boolean logic on port signals, and a multi-sense converter (MSC) block optimized for water-tolerant capacitive sensing with automatic hardware tuning - all coordinated via the ModusToolbox™ PDL API stack.

FAQ
What is the maximum operating temperature grade for CY8C4148LDAS543XQLA1?
This part is qualified to AEC-Q100 Grade-S, with guaranteed operation from –40°C to +105°C ambient temperature. It uses automotive-grade packaging and undergoes extended reliability testing including HTOL and TC, meeting stringent automotive thermal cycling requirements for under-hood and dashboard applications.
Does CY8C4148LDAS543XQLA1 support CAN FD bit-rate switching?
Yes - the integrated CAN FD controller supports bit-rate switching between nominal (≤1 Mbps) and data phases (up to 5 Mbps), with hardware timestamping, flexible data length (up to 64 bytes), and error confinement per ISO 11898-1:2015. Configuration is handled via ModusToolbox™ CAN FD middleware.
Can the SAR ADC operate during Deep Sleep mode?
No - the 12-bit SAR ADC requires Active or Sleep mode. However, the device supports Deep Sleep with operational analog blocks including the two CTBm opamps and dual low-power comparators, enabling wake-up events from analog thresholds without full CPU activation.
How many GPIO pins support CAPSENSE™ functionality?
All 84 programmable GPIO pins support CAPSENSE™ sensing, with hardware-accelerated multi-sense conversion (MSC) and SmartSense auto-tuning. Each pin can be individually configured as a shield, sensor, or mutual-capacitance electrode - no external components required for baseline compensation or noise rejection.
