Product details
Overview
CY8C6144LQI-S4F92 from Infineon is a dual-core Arm® Cortex®-M4F/M0+ PSoC™ 61 MCU 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-S4F92 datasheet, CY8C6144LQI-S4F92 pinout, CY8C6144LQI-S4F92 application, or CY8C6144LQI-S4F92 equivalent, key selection criteria include Deep Sleep current (7 µA), dual-CPU isolation architecture, on-chip DC-DC buck converter (<1 µA quiescent), QSPI XIP support, and hardware TRNG + AES/SHA accelerators.
Technical Context
The device 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 reserved exclusively for system-level functions including security boot, power management, and peripheral arbitration-no user application code runs on M0+.
Its programmable analog/digital fabric includes two synchronized 12-bit 2-Msps SAR ADCs, one 12-bit DAC (<2 µs settling), two opamps, two low-power comparators active in Deep Sleep, and CapSense™ CSD with SmartSense auto-tuning-enabling simultaneous sensing, signal conditioning, and secure connectivity without external components.

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 |
|---|---|---|---|
| STM32WB55RGV6 | Single Cortex-M4 + Cortex-M0+; no integrated CAN FD; 256 KB flash but only 64 KB SRAM; lacks hardware TRNG and dedicated CapSense™ | Targeted at Bluetooth LE + Zigbee dual-radio systems; insufficient for CAN-based industrial backhaul or high-channel-count analog sensing | Select when BLE coexistence and RF certification priority outweigh analog integration and CAN FD requirements |
| NXP LPC55S69JBD100 | Dual Cortex-M33 cores (both user-accessible); no CAN FD; 256 KB flash/320 KB SRAM; includes DSP extensions but no segment LCD driver or Smart I/O | Better for audio preprocessing or motor control; lacks Deep Sleep-optimized analog peripherals and secure boot partitioning | Choose for compute-intensive DSP workloads where M33 vector extensions matter more than ultra-low-power sensing or UI driving |
Compared with STM32WB55RGV6 and LPC55S69JBD100, CY8C6144LQI-S4F92 uniquely combines CAN FD, hardware-isolated secure boot, Deep Sleep-optimized analog, and Smart I/O-making it optimal for battery-powered industrial gateways and medical wearables demanding both security and sensing autonomy.

FAQ
Is the Cortex-M0+ core accessible for user application code?
No. The Cortex-M0+ core in CY8C6144LQI-S4F92 is reserved exclusively for system-level functions-including secure boot, power management, interrupt arbitration, and peripheral control-and cannot be programmed with user application firmware. All application code must run on the Cortex-M4F core.
Does this part support external QSPI flash with execute-in-place (XIP)?
Yes. The QSPI/SMIF interface supports true XIP from external Quad SPI flash at up to 320 Mbps, with on-the-fly AES-128 decryption, 4 KB instruction cache, and hardware prefetch-enabling secure, low-power code execution without loading into internal RAM.
What is the lowest achievable system current in Deep Sleep mode?
The guaranteed maximum Deep Sleep current is 7 µA with 64 KB of SRAM retained, measured at 3.3 V and 25°C per Infineon datasheet 002-33480 Rev. *H. This includes active clocking for RTC, comparators, and CapSense™, with the DC-DC buck converter enabled.
Can the integrated CAN FD block operate independently of the M4F core?
Yes. The CAN FD peripheral includes dedicated message RAM, transmit/receive FIFOs, and programmable filters-allowing autonomous operation during Deep Sleep. It can wake the M4F core on frame reception or error events without CPU polling.
