Product details
Overview
CY8C6144LQQ-S4F92 from Infineon is a dual-core Arm® Cortex®-M4F/M0+ PSOC™ 61 microcontroller optimized for secure, ultra-low-power IoT edge nodes. It integrates 256 KB flash, 128 KB SRAM, hardware cryptography accelerators, CAN FD, USB Full-Speed, and programmable analog/digital blocks. Its 7 µA Deep Sleep current with 64 KB SRAM retention enables battery-powered sensor hubs and wearable health monitors.
For engineers reviewing the CY8C6144LQQ-S4F92 datasheet, CY8C6144LQQ-S4F92 pinout, CY8C6144LQQ-S4F92 application, or CY8C6144LQQ-S4F92 equivalent, key selection criteria include dual-CPU partitioning (M4F for application, M0+ reserved for system functions), on-chip DC-DC buck converter (<1 µA quiescent), QSPI XIP with 4 KB cache, and CAPSENSE™ CSD with SmartSense auto-tuning.
Technical Context
The device implements a tightly coupled dual-CPU architecture where the 150-MHz Cortex-M4F executes application firmware with FPU and MPU, while the 100-MHz Cortex-M0+ handles low-level system services including boot, security, and power management-no user application code runs on M0+. Inter-processor communication uses hardware IPC channels with doorbell interrupts and shared memory.
Its programmable subsystems include two independent 12-bit SAR ADCs (2 Msps, synchronized sampling), a 12-bit DAC (<2 µs settling), two opamps, two low-power comparators (active in Deep Sleep), and a dedicated CAPSENSE™ CSD block supporting self/mutual sensing with hardware-accelerated SmartSense tuning.

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 |
|---|---|---|---|
| CY8C6247FDI-D52 | Same PSOC™ 6 platform but with 1 MB flash, 384 KB SRAM, and 100-pin TQFP package; lacks CAN FD block | Better suited for complex BLE mesh gateways requiring large OTA image storage and multiple concurrent protocols | Select when >512 KB flash or additional GPIOs are required; avoid if CAN FD or compact 80-pin footprint is mandatory |
| STM32WB55RGV | Single-core Cortex-M4 with integrated BLE radio; no M0+ companion core; 1 MB flash, 256 KB SRAM; no on-chip DC-DC or CAPSENSE™ | Optimized for BLE-centric endpoints where RF integration outweighs need for programmable analog or ultra-low-power Deep Sleep | Choose for cost-sensitive BLE peripherals; reject if analog subsystem flexibility, CAN FD, or sub-10 µA Deep Sleep is required |
Compared with CY8C6144LQQ-S4F92, CY8C6247FDI-D52 offers higher memory density but sacrifices CAN FD and compact packaging, while STM32WB55RGV trades programmable analog, dual-core partitioning, and ultra-low-power analog peripherals for integrated wireless-making CY8C6144LQQ-S4F92 uniquely balanced for secure, sensor-rich, wired/wireless hybrid edge nodes.

FAQ
Is the Cortex-M0+ core user-programmable in CY8C6144LQQ-S4F92?
No. The Cortex-M0+ core in CY8C6144LQQ-S4F92 is reserved exclusively for system-level functions including secure boot, power management, and peripheral arbitration. Application firmware must run solely on the Cortex-M4F core. This architectural partitioning enforces security isolation and simplifies certification for functional safety standards.
Does CY8C6144LQQ-S4F92 support external memory execution with encryption?
Yes. Its QSPI/SMIF interface supports Execute-In-Place (XIP) from external Quad SPI Flash with real-time AES-128 decryption. The 4 KB instruction cache reduces active fetch current, and on-the-fly encryption ensures firmware confidentiality without software overhead-critical for secure OTA updates in field-deployed devices.
What is the lowest achievable active current at 150 MHz operation?
At 150 MHz CPU frequency with all peripherals disabled and core voltage set to 0.9 V, typical active current is 4.2 mA (measured per datasheet Section 6.2.2). This value assumes VDDD = 0.9 V, VDDIO = 3.3 V, and use of the on-chip DC-DC buck converter. Actual current scales linearly with active peripheral count and I/O switching activity.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. The CAPSENSE™ CSD block operates autonomously in System Deep Sleep mode, performing full self- and mutual-capacitance scans with SmartSense auto-tuning. Wake-up events (e.g., touch detection) trigger interrupt to the Cortex-M4F without exiting Deep Sleep-enabling sub-10 µA average power in always-on UI applications.
