Product details
Overview
CY8C6144LQI-S4F82 from Infineon is a dual-core Arm® Cortex®-M4F/M0+ PSOC™ 61 microcontroller with 256 KB flash, 128 KB SRAM, integrated CAN FD, USB Full-Speed, and hardware cryptography acceleration-designed for secure, ultra-low-power IoT edge nodes requiring real-time sensor fusion and wireless coexistence.
For engineers reviewing the CY8C6144LQI-S4F82 datasheet, CY8C6144LQI-S4F82 pinout, CY8C6144LQI-S4F82 application, or CY8C6144LQI-S4F82 equivalent, this device supports concurrent BLE/Wi-Fi coexistence via Smart I/O and Deep Sleep SCB, delivers 7 µA Deep Sleep current with 64 KB SRAM retention, and integrates TRNG + AES-256 + SHA-256 accelerators for secure boot and OTA updates.
Technical Context
The CY8C6144LQI-S4F82 implements a tightly coupled dual-CPU subsystem: the 150-MHz Cortex-M4F handles application processing with FPU and MPU, while the 100-MHz Cortex-M0+ is dedicated to system-level tasks including security monitoring, power management, and peripheral offload-preventing user access to ensure deterministic RTOS scheduling and secure enclave isolation.
Its programmable analog/digital fabric includes two synchronized 12-bit 2-Msps SAR ADCs, a 12-bit DAC with <2-μs settling, six configurable SCBs (five runtime + one Deep Sleep), and a dedicated CAN FD controller compliant with ISO 11898-1:2015 supporting data rates up to 5 Mbps-enabling time-critical industrial control and automotive diagnostics.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core secure MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32WB55RGV | Single-core Cortex-M4 + Cortex-M0+ radio coprocessor; lacks CAN FD, integrated SMIF, and hardware TRNG | Optimized for BLE/Wi-Fi SoC use; no native CAN FD or segment LCD driver | Select when RF integration outweighs need for industrial bus interfaces and analog subsystem depth |
| RA6M5G32FP | Single-core Cortex-M33 with TrustZone; no Smart I/O, no Deep Sleep SCB, no CAPSENSE™ | Focused on functional safety (IEC 61508 SIL3); lacks ultra-low-power analog features and capacitive sensing | Select for ASIL-B automotive body control where safety certification trumps power/peripheral flexibility |

FAQ
Does CY8C6144LQI-S4F82 support JTAG debugging?
Yes-it features a standard SWD/SWJ debug interface with full JTAG ID visibility (32-bit Silicon ID). The device supports real-time trace, memory inspection, and secure debug disable via eFuse configuration. Debug access can be permanently locked after production programming to prevent reverse engineering.
What is the maximum operating temperature for this part?
CY8C6144LQI-S4F82 is rated for industrial temperature range: –40 °C to +85 °C ambient. Its on-chip temperature sensor connects directly to the SAR ADC and is calibrated across this range, enabling closed-loop thermal management in fanless enclosures.
Can the Cortex-M0+ core be used for application code?
No-the Cortex-M0+ in CY8C6144LQI-S4F82 is reserved exclusively for system functions including interrupt routing, power state management, and security monitor tasks. Application firmware must run solely on the Cortex-M4F core; M0+ firmware is preloaded in ROM and non-modifiable.
Is external flash required for XIP operation?
No-XIP (Execute-In-Place) is supported directly from external Quad SPI Flash via the SMIF interface, but the device includes 256 KB on-chip flash sufficient for most standalone applications. External flash is optional and used only for firmware expansion, asset storage, or secure key partitioning.
