Product details
Overview
CYS0644ABZI-S2D44 from Infineon is a PSOC™ 64 "Standard Secure" MCU featuring dual Arm® Cortex®-M4F (150 MHz) and Cortex®-M0+ (100 MHz) CPUs, 1856-KB flash, 944-KB SRAM, hardware-based root-of-trust, and Amazon FreeRTOS PSA Level-2 compliance - deployed in secure IoT edge nodes requiring TLS, OTA updates, and attestation.
For engineers reviewing the CYS0644ABZI-S2D44 datasheet, CYS0644ABZI-S2D44 pinout, CYS0644ABZI-S2D44 application, or CYS0644ABZI-S2D44 equivalent, this page delivers verified package mapping (124-BGA), confirmed power modes (7 µA Deep Sleep), validated security features (immutable boot, ECC signature validation), and real-world use context for AWS-connected embedded systems.
Technical Context
The device implements a hardened dual-core architecture where the M4F executes application code with floating-point and MPU support, while the M0+ is reserved exclusively for system-level security services including TF-M SPE and bootloader orchestration. Its memory subsystem includes RWW-capable flash with two 8-KB CPU-specific caches and three independent SRAM blocks enabling selective retention during low-power states.
Security is anchored in immutable boot firmware, on-die eFuse-based key provisioning, and hardware-accelerated cryptography (ECC, AES, TRNG). Clocking integrates dual PLLs, FLL, and fractional dividers to support dynamic voltage/frequency scaling across six power modes - with Deep Sleep current measured at 7 µA while retaining 64 KB SRAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RP2040 | No hardware root-of-trust, no PSA certification, no dedicated secure core; relies on software-only TLS stack | Suitable for cost-sensitive consumer devices without regulatory security mandates | Select only if PSA Level-2 compliance and immutable boot are not required |
| STM32U575 | Single-core Cortex-M33 with TrustZone; lacks dual-core separation and Amazon FreeRTOS PSA integration | Better for ST ecosystem users needing TrustZone but not AWS-native OTA or TF-M SPE | Choose when leveraging STM32CubeMX toolchain and existing ST middleware is prioritized over AWS integration |
Compared with RP2040 and STM32U575, CYS0644ABZI-S2D44 uniquely delivers pre-integrated Amazon FreeRTOS PSA Level-2 compliance, dual-core hardware isolation for secure runtime, and factory-provisioned device identity - making it optimal for AWS-connected products requiring certified security out-of-box.
