Product details
Overview
CY8C4146LQS-S263T from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade PSoC™ 4100S Plus microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 128 KB flash, 16 KB SRAM, and integrated CAPSENSE™ capacitive sensing with SmartSense auto-tuning. It includes five reconfigurable serial communication blocks (SCB), eight 16-bit TCPWM units, and a CAN 2.0B controller with time-triggered support - deployed in automotive body control modules requiring robust touch HMI and motor timing.
For engineers reviewing the CY8C4146LQS-S263T datasheet, CY8C4146LQS-S263T pinout, CY8C4146LQS-S263T application, or CY8C4146LQS-S263T equivalent, key selection criteria include its AEC-Q100 qualification, Deep Sleep current (2.5 µA), 54 GPIO count with full CAPSENSE™/analog/digital reassignment, and CAN+TCPWM coexistence for safety-critical actuator control.
Technical Context
The device implements a tightly coupled programmable analog-digital architecture where continuous-time opamps and SAR ADCs share routing resources with Smart I/O logic blocks, enabling real-time sensor signal conditioning and Boolean decision-making without CPU intervention. Its clock system integrates a 4–33 MHz ECO, PLL, WCO, and ±2% IMO - all supporting dynamic frequency scaling across operational modes.
The CAN 2.0B block operates independently of SCBs and supports TTCAN for deterministic message scheduling, while eight TCPWM blocks provide quadrature decoding, kill-signal triggering via comparator inputs, and center-aligned PWM for BLDC motor commutation - all synchronized to a common clock domain.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144HAT0MLHT | ARM Cortex-M4F core, 112 MHz; includes Ethernet MAC but lacks integrated CAPSENSE™ | Targeted at gateway ECUs requiring CAN FD + Ethernet; requires external touch controller for HMI | Select when higher compute throughput and network connectivity outweigh touch integration needs |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; AEC-Q100 Grade-2 (–40°C to +105°C); no CAN FD or hardware TRNG | Suitable for cost-sensitive body electronics with basic CAN 2.0A and no cryptographic requirements | Select for legacy 16-bit migration paths where security and advanced HMI are not required |
