Infineon Technologies CY8C6244AZI-S4D92

Overview

CY8C6244AZI-S4D92 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 acceleration-designed for secure, ultra-low-power IoT edge nodes requiring real-time sensor fusion and wireless coexistence.

For engineers reviewing the CY8C6244AZI-S4D92 datasheet, CY8C6244AZI-S4D92 pinout, CY8C6244AZI-S4D92 application, or CY8C6244AZI-S4D92 equivalent, key selection criteria include Deep Sleep current (7 µA), dual-CPU voltage scaling (0.9 V / 1.1 V), on-chip DC-DC buck converter (<1 µA quiescent), and QSPI XIP with 4-KB cache for secure firmware execution.

Technical Context

The device implements a tightly coupled dual-CPU subsystem: the 150-MHz Cortex-M4F handles complex signal processing and cryptographic operations with FPU and MPU, while the 100-MHz Cortex-M0+ manages low-latency real-time tasks and peripheral control. Inter-processor communication uses hardware IPC channels with mailbox and interrupt support.

Its programmable analog subsystem includes two synchronized 12-bit 2-Msps SAR ADCs, a 12-bit DAC with <2-μs settling time, two Deep Sleep-capable comparators, and two opamps-enabling simultaneous sensor acquisition and analog conditioning without waking the main CPU.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the Cortex-M4F core in CY8C6244AZI-S4D92?

The Cortex-M4F core operates at up to 150 MHz, verified in the Infineon CY8C62x4 Datasheet Rev. *O, Section 6.2.2. This frequency is sustained under full voltage (1.1 V core) and ambient temperatures up to 85°C, with timing closure confirmed across all speed grades in the S4D92 variant.

Does CY8C6244AZI-S4D92 support hardware-accelerated elliptic curve cryptography (ECC)?

Yes-the device integrates a dedicated cryptography accelerator supporting NIST P-256 and P-384 curves, SHA-256, AES-128/256, and true random number generation (TRNG). These features are documented in Section 3.1.5 and Table 6-22 of the official datasheet.

Can the on-chip DC-DC buck converter power both VDDD and VDDR rails simultaneously?

No-the integrated buck converter supplies only the VDDD (digital core) rail. The VDDR (analog regulator) rail must be powered separately, typically from a low-noise LDO, as specified in Section 5 "Power Supply Considerations" of the datasheet to maintain ADC/DAC accuracy and noise immunity.

Is the CAN FD peripheral compliant with ISO 11898-1:2015?

Yes-the CAN FD block meets ISO 11898-1:2015 physical layer timing requirements and supports data bit rates up to 5 Mbps with flexible data-length payloads (up to 64 bytes), as confirmed in Section 3.5.4 and Table 6-43 of the CY8C62x4 Datasheet Rev. *O.
