Product details
Overview
CY8C4148AZES598XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade 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 CAPSENSE™ multi-sense converter for high-SNR capacitive sensing. It supports deep-sleep operation at 2.5 µA digital current with active analog blocks and targets body control modules, smart sensors, and automotive HMI systems.
For engineers reviewing the CY8C4148AZES598XQLA1 datasheet, CY8C4148AZES598XQLA1 pinout, CY8C4148AZES598XQLA1 application, or CY8C4148AZES598XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep analog retention, SAR ADC differential mode accuracy (±1.5 LSB INL), MSC water-tolerance capability, and GPIO reconfigurability 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 hardware message filtering and FIFO buffering. Its clock system combines ECO (4–33 MHz) + PLL for 48 MHz core timing, WCO (32 kHz) for RTC, and ILO (40 kHz) for Deep Sleep wake-up.
Analog subsystem includes two CTBm opamps supporting ADC input buffering and comparator modes, a 12-bit 1-Msps SAR ADC with built-in temperature sensor and channel sequencer, and dual low-power comparators operational in Deep Sleep. The MSC block delivers >5:1 SNR and SmartSense auto-tuning for robust capacitive touch in wet environments.

FAQ
What is the maximum operating temperature range for CY8C4148AZES598XQLA1?
This device is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. Electrical specifications including ADC accuracy, CAN FD timing margin, and Deep Sleep current are guaranteed across this full range per datasheet Section 7.2.1 and Table 7-2.
Does CY8C4148AZES598XQLA1 support hardware-based CAN FD bit rate switching?
Yes, it implements full CAN FD protocol compliance including automatic bit rate switching between nominal (≤1 Mbps) and data (up to 5 Mbps) phases. The CAN FD block includes dedicated hardware for bit timing configuration, CRC calculation, and flexible data length up to 64 bytes per frame.
Can the SAR ADC perform simultaneous sampling on multiple channels?
No, the 12-bit SAR ADC has a single conversion engine with a channel sequencer that supports automated scanning of up to 32 inputs. It does not support true simultaneous sampling, but achieves effective multi-channel acquisition via hardware-triggered sequencing with <1 µs inter-channel delay.
Is ModusToolbox™ required to develop firmware for this MCU?
No, ModusToolbox™ is Infineon's recommended IDE with PDL libraries and configurator tools, but the device is Arm®-compliant and supports GCC-based toolchains (e.g., GNU Arm Embedded Toolchain) and debuggers using SWD interface.
