Product details
Overview
CY8C4148AZSS568XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified 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™ with SmartSense auto-tuning. It serves as a reconfigurable system-on-chip for automotive body control, sensor fusion, and human-machine interface applications.
For engineers reviewing the CY8C4148AZSS568XQLA1 datasheet, CY8C4148AZSS568XQLA1 pinout, CY8C4148AZSS568XQLA1 application, or CY8C4148AZSS568XQLA1 equivalent, key selection considerations include CAN FD timing compliance, Deep Sleep current (2.5 µA), MSC SNR (>5:1), programmable analog routing, and ModusToolbox™ API support for rapid CAPSENSE™ and TCPWM development.
Technical Context
The device implements a single-layer AHB-Lite interconnect between CPU, memory, and peripherals, enabling deterministic latency for real-time automotive tasks. Its programmable analog subsystem includes two CTBm opamps supporting ADC input buffering and comparator modes, plus two low-power comparators operable in Deep Sleep mode - critical for always-on sensing.
Digital flexibility is delivered via five reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART/LIN, eight 16-bit TCPWM blocks with quadrature decode and kill-signal triggering, and a dedicated CAN FD controller compliant with ISO 11898-1:2015 supporting data rates up to 5 Mbps and payload lengths up to 64 bytes.
Key Specifications

Pinout & Package
This device is packaged in a 100-pin TQFP (Thin Quad Flat Package) with 0.5 mm pitch, lead-free and RoHS-compliant, designed for automotive PCB assembly and thermal reliability under extended temperature operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO7 | I/O power supply domains | Independent voltage domains per port group allow mixed-voltage interfacing (1.8 V to 5.5 V) and isolation of noise-sensitive analog sections. |
| P0[0]–P7[7] | Programmable GPIO | Each pin supports CAPSENSE™ electrode, analog input, digital logic, or LCD segment drive - configured dynamically via firmware. |

Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual threshold tuning and compensates for environmental drift in production systems. |
| Programmable analog routing | Flexible interconnect between SAR ADC, opamps, comparators, and GPIOs enables custom signal chains without external components or PCB redesign. |
| Deep Sleep with active analog | Opamps and comparators remain functional while CPU and digital logic are powered down - enables continuous sensor monitoring at sub-µA system level. |
| Crypto accelerator | Hardware AES-128/256, SHA-256, TRNG, and CRC engines offload security-critical operations from CPU - essential for secure boot and OTA update integrity. |
| Reconfigurable SCBs | Five independent serial blocks each configurable at runtime as I²C master/slave, SPI master/slave, UART, or LIN slave - reduces BOM count and simplifies protocol migration. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144W | ARM Cortex-M4F core, 112 MHz; includes Ethernet MAC but no integrated CAPSENSE™ or MSC block. | Targeted at gateway and domain controller roles requiring higher compute throughput and networking; lacks hardware-accelerated touch sensing. | Select when Ethernet or floating-point math is required; avoid if CAPSENSE™ integration and low-power touch are primary needs. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; supports CAN 2.0B only (no CAN FD); 10-bit ADC, no hardware crypto acceleration. | Cost-optimized for basic body electronics where CAN FD bandwidth and cryptographic security are not mandated. | Choose for legacy CAN-only designs with tight BOM constraints; not suitable for new CAN FD or secure boot architectures. |
Compared with S32K144W and RL78/F14, CY8C4148AZSS568XQLA1 uniquely combines CAN FD, hardware CAPSENSE™ tuning, and sub-µA Deep Sleep analog operation - making it optimal for next-generation automotive HMI and distributed sensor nodes where integration density and power efficiency are design priorities.

FAQ
What is the maximum operating temperature grade for CY8C4148AZSS568XQLA1?
CY8C4148AZSS568XQLA1 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per test condition 3.1.1 of AEC-Q100 Rev-H and applies to the full 100-pin TQFP package variant with specified derating curves for junction temperature under sustained load conditions.
Does this part include hardware support for secure boot?
Yes - the device integrates a dedicated cryptography accelerator supporting AES-128/256 encryption/decryption, SHA-256 hashing, true random number generation (TRNG), and CRC-32 computation. These functions are accessible via PDL APIs and used by ModusToolbox™ Secure Boot Manager to validate signed firmware images before execution.
Can the SAR ADC perform simultaneous sampling across multiple channels?
No - the 12-bit SAR ADC uses a single conversion core with a channel sequencer that supports automatic scanning and signal averaging, but does not provide true simultaneous sampling. For correlated multi-channel acquisition, external sample-and-hold circuits or time-interleaved firmware sequencing must be implemented.
Is CAN FD configuration supported through ModusToolbox™ tools?
Yes - ModusToolbox™ 3.x includes a dedicated CAN FD configuration editor within the Peripheral Configuration Tool (PCT), allowing register-level setup of bit timing, data phase arbitration, payload length, and callback-driven interrupt handling. Generated code is fully compatible with the PDL v3.1.0 CAN FD driver stack.
