Infineon Technologies CY8C6244AZI-S4D62

Overview

CY8C6244AZI-S4D62 from Infineon is a dual-core Arm® Cortex®-M4F/M0+ PSOC™ 62 microcontroller with 256 KB flash, 128 KB SRAM, integrated CAN FD, USB Full-Speed, and hardware cryptography accelerators. It operates from 1.7 V to 3.6 V, achieves 7 µA Deep Sleep current with 64 KB SRAM retention, and supports XIP from external Quad-SPI Flash at up to 320 Mbps-targeted for secure, ultra-low-power IoT edge nodes requiring real-time sensor fusion and wireless coexistence.

For engineers reviewing the CY8C6244AZI-S4D62 datasheet, CY8C6244AZI-S4D62 pinout, CY8C6244AZI-S4D62 application, or CY8C6244AZI-S4D62 equivalent, key selection criteria include dual-CPU power/performance tradeoff, on-chip DC-DC quiescent current (<1 µA), Deep Sleep SCB availability, Smart I/O Boolean logic capability during system sleep, and TRNG-enabled secure boot implementation.

Technical Context

The device implements a tightly coupled dual-CPU subsystem: a 150-MHz Cortex-M4F with FPU and MPU handles real-time signal processing and security-critical tasks, while a 100-MHz Cortex-M0+ manages low-power peripheral orchestration and protocol stacks. Inter-processor communication (IPC) uses dedicated hardware mailboxes with interrupt signaling and memory-mapped shared RAM.

Clock architecture integrates multiple independent oscillators-including 8-MHz IMO (±2%), 32-kHz ILO, programmable crystal oscillators (16–35 MHz and 32 kHz), PLL, and FLL-enabling dynamic clock source switching per power mode. The SMIF controller supports encrypted Execute-In-Place with 4-KB cache and quad/dual/single SPI modes, decoupling code execution from flash access latency.

FAQ

What is the maximum operating frequency of each CPU core in the CY8C6244AZI-S4D62?

The CY8C6244AZI-S4D62 features a 150-MHz Arm Cortex-M4F core with floating-point unit and memory protection unit, and a 100-MHz Cortex-M0+ core with single-cycle multiply and MPU. Both cores operate at their rated frequencies under 3.3 V supply and 25°C ambient, with dynamic voltage scaling supporting 1.1 V or 0.9 V core logic operation.

Does the CY8C6244AZI-S4D62 support hardware-accelerated cryptographic operations?

Yes-it integrates dedicated hardware accelerators for AES-128/256, SHA-256, ECC (NIST P-256), and RSA-2048, plus a True Random Number Generator (TRNG). These units operate independently of the CPU cores, enabling concurrent encryption/decryption during active firmware execution without performance degradation.

Can the CY8C6244AZI-S4D62 execute code directly from external Quad-SPI Flash?

Yes-via the Serial Memory Interface (SMIF), it supports Execute-In-Place (XIP) from external Quad-SPI Flash with on-the-fly AES-128 decryption and a 4-KB instruction cache. Throughput reaches 320 Mbps in quad mode, and the feature remains functional in all active power modes except Hibernate.

How many GPIOs support capacitive sensing, and what CapSense™ modes are available?

All 62 GPIOs are CapSense™-capable. The device supports Capacitive Sigma-Delta (CSD) with both self-capacitance and mutual-capacitance sensing, dynamic reconfiguration between modes, automatic hardware tuning (SmartSense™), and Deep Sleep operation-enabling touch, proximity, and liquid-tolerant interfaces with <60 dB SNR.
