Infineon Technologies CY8C6245LQI-S3D62

Overview

CY8C6245LQI-S3D62 from Infineon is a dual-core Arm® Cortex®-M4F/M0+ PSOC™ 62 microcontroller with 512-KB flash, 256-KB SRAM, integrated CAN FD, USB Full-Speed, and hardware cryptography accelerator-designed for secure, ultra-low-power IoT edge nodes requiring concurrent real-time control and wireless protocol stack execution.

For engineers reviewing the CY8C6245LQI-S3D62 datasheet, CY8C6245LQI-S3D62 pinout, CY8C6245LQI-S3D62 application, or CY8C6245LQI-S3D62 equivalent, this MCU delivers verified low-power operation (7 µA Deep Sleep with 64-KB SRAM retention), on-chip DC-DC buck converter (<1 µA quiescent), and programmable analog/digital subsystems enabling rapid sensor fusion and human interface development.

Technical Context

The device implements a tightly coupled dual-CPU architecture: the 150-MHz Cortex-M4F handles complex firmware tasks (e.g., protocol stacks, signal processing) while the 100-MHz Cortex-M0+ manages real-time peripherals and low-power state coordination. Inter-processor communication (IPC) and shared memory enable deterministic task partitioning without bus contention.

Its programmable analog subsystem includes a 12-bit 2-Msps SAR ADC with 16-channel sequencer and hardware averaging, two deep-sleep-capable comparators, and an integrated temperature sensor-all routed through a unified I/O matrix supporting overvoltage-tolerant (OVT) pins and Smart I/O Boolean logic during system Deep Sleep.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of each CPU core in CY8C6245LQI-S3D62?

The Cortex-M4F core operates up to 150 MHz with single-cycle multiply and floating-point unit; the Cortex-M0+ core runs at up to 100 MHz with single-cycle multiply. Both include memory protection units (MPUs) and support independent voltage scaling (0.9 V or 1.1 V) to optimize performance versus active current draw.

Does CY8C6245LQI-S3D62 support hardware encryption acceleration?

Yes-it integrates a dedicated cryptography accelerator supporting AES-128/256, SHA-1/224/256, RSA up to 4096-bit, ECC NIST P-256/P-384, and true random number generation (TRNG). All cryptographic operations execute in protected memory space with execute-only permissions enforced by hardware.

Can the SAR ADC operate during Deep Sleep mode?

No-the 12-bit SAR ADC requires active CPU clocking and cannot sample in Deep Sleep. However, two low-power comparators remain fully functional in Deep Sleep and can trigger wake events or drive Smart I/O logic without CPU involvement.

What package type and pin count does CY8C6245LQI-S3D62 use?

CY8C6245LQI-S3D62 uses a 100-pin TQFP package (14 mm × 14 mm, 0.5-mm pitch) with 64 GPIOs, including two overvoltage-tolerant (OVT) pins, eight Smart I/O pins, and dedicated USB/CAN FD/SMIF interface signals mapped to fixed ballouts per the datasheet pinout diagram.
