Product details
Overview
CY8C624ABZI-S2D44T from Infineon is a dual-core PSOC™ 62 MCU featuring a 150-MHz Arm® Cortex®-M4F and 100-MHz Cortex®-M0+ CPU, 2048-KB flash, 1024-KB SRAM, and integrated CAPSENSE™, USB FS, QSPI/XIP, and hardware cryptography accelerator - designed for secure, ultra-low-power IoT edge nodes with LCD display and capacitive touch interfaces.
For engineers reviewing the CY8C624ABZI-S2D44T datasheet, CY8C624ABZI-S2D44T pinout, CY8C624ABZI-S2D44T application, or CY8C624ABZI-S2D44T equivalent, key selection criteria include dual-CPU power efficiency (27 µA/MHz @ 0.9 V M4), Deep Sleep current (7 µA w/64-KB SRAM retention), on-chip DC-DC converter (<1 µA quiescent), and SMIF throughput up to 640 Mbps for external flash XIP.
Technical Context
The device implements a tightly coupled dual-CPU subsystem with IPC and shared memory mapping, enabling asymmetric processing: M4 handles complex real-time tasks (e.g., audio decoding, crypto), while M0+ manages low-power system control and peripheral orchestration in Deep Sleep. Both cores operate at user-selectable 1.1 V or 0.9 V supply voltages.
Its programmable analog-digital fabric includes a 12-bit 2-Msps SAR ADC with 16-channel sequencer and averaging, two Deep Sleep-capable comparators, and CAPSENSE™ CSD with SmartSense™ auto-tuning - all synchronized via a unified trigger-routing network supporting comparator-triggered TCPWM kill signals and DMA-initiated ADC sampling.

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 |
|---|---|---|---|
| CY8C6247BZI-D54 | Same die, but 128-pin TQFP package; higher pin count enables more SCBs (13 vs. 10), additional USB PHY, and full 102 GPIO access | Better suited for prototyping and systems requiring multiple UART/I2C peripherals or external debug headers | Select when board layout allows larger footprint and design requires maximum peripheral flexibility over ultra-compact size |
| RP2040 | Single-core ARM Cortex-M0+ (133 MHz), no hardware crypto accelerator, no CAPSENSE™, no SMIF/XIP, 264-KB SRAM | Lacks dual-CPU partitioning, Deep Sleep retention granularity, and analog subsystem integration required for certified IoT endpoints | Choose only for cost-sensitive, non-secure, low-complexity control applications where Infineon's security and analog features are unnecessary |
Compared with CY8C6247BZI-D54, the CY8C624ABZI-S2D44T trades pin count for ultra-low-power WLCSP integration ideal for wearables; versus RP2040, it delivers certified security, analog integration, and deterministic low-power operation essential for industrial and medical edge devices.

FAQ
What is the maximum operating frequency of each CPU core in CY8C624ABZI-S2D44T?
The Cortex-M4F core operates at up to 150 MHz, and the Cortex-M0+ core at up to 100 MHz. Both frequencies are achievable under 1.1 V core supply; at 0.9 V, maximum frequencies are reduced to maintain timing closure and power efficiency, with confirmed operation at 120 MHz (M4) and 80 MHz (M0+) per Infineon's validated characterization data.
Does CY8C624ABZI-S2D44T support execute-in-place (XIP) from external flash?
Yes - its Serial Memory Interface (SMIF) supports XIP from external quad/octal SPI flash with on-the-fly AES-256 decryption, 4-KB instruction cache, and throughput up to 640 Mbps in octal mode. This eliminates need for external RAM loading and reduces boot time by >40% compared to copy-to-RAM execution.
How many GPIOs are available, and what special capabilities do they offer?
CY8C624ABZI-S2D44T provides up to 102 programmable GPIOs, including six overvoltage-tolerant (OVT) pins rated to 5.5 V. Two Smart I/O ports (16 pins total) support Boolean logic operations during Deep Sleep, and all GPIOs feature configurable drive strength, slew rate, and 12 programmable analog functions (e.g., ADC input, comparator input, CAPSENSE™ electrode).
Is hardware cryptographic acceleration included, and which algorithms are supported?
Yes - the integrated cryptography accelerator supports AES-128/256 (ECB/CBC/CTR/GCM), SHA-224/256, ECC-256 (NIST P-256), RSA-2048, and true random number generation (TRNG). All operations execute in constant time with dedicated DMA channels, enabling secure boot, TLS handshake offload, and key wrapping without software-side timing leakage.
