Product details
Overview
CY8C6248AZI-S2D44 from Infineon is a dual-core Arm® Cortex®-M4F/M0+ PSOC™ 62 MCU with 2048 KB flash, 1024 KB SRAM, and integrated CAPSENSE™, QSPI/XIP, USB FS, 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 CY8C6248AZI-S2D44 datasheet, CY8C6248AZI-S2D44 pinout, CY8C6248AZI-S2D44 application, or CY8C6248AZI-S2D44 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 with on-the-fly encryption.
Technical Context
The device implements a tightly coupled dual-CPU subsystem where the Cortex-M4F handles complex tasks (e.g., protocol stacks, signal processing) while the Cortex-M0+ manages low-latency peripherals and power state coordination via IPC and shared memory. Both cores operate at independently configurable voltages (0.9 V or 1.1 V) to optimize active-mode efficiency.
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™ sigma-delta with SmartSense™ auto-tuning - enabling robust capacitive touch in battery-powered human interface applications without host CPU intervention.

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 |
|---|---|---|---|
| CY8C6247FDI-S2D44 | Same die, but 124-ball BGA package; no WLCSP; higher thermal mass and larger PCB footprint | Better suited for high-reliability industrial control with extended temperature range (-40°C to +105°C vs. -40°C to +85°C) | Select when board-level rework tolerance, thermal dissipation, or legacy BGA assembly infrastructure is required |
| STM32WB55RGV | Single Cortex-M4 core + dedicated radio coprocessor; no M0+ subsystem; 1 MB flash; no on-chip DC-DC | Optimized for Bluetooth LE + Zigbee coexistence; lacks CAPSENSE™, Smart I/O, and SMIF encryption acceleration | Choose when RF integration priority outweighs dual-CPU deterministic scheduling and ultra-low-power analog features |
Compared with CY8C6247FDI-S2D44, the S2D44 variant offers superior miniaturization and lower system-level power in space-constrained battery devices; versus STM32WB55RGV, it delivers deeper hardware security, richer analog integration, and true dual-core concurrency - critical for real-time sensor fusion and secure edge AI inference.

FAQ
What is the maximum operating frequency of the Cortex-M4F core in CY8C6248AZI-S2D44?
The Cortex-M4F core operates at up to 150 MHz, confirmed in the "CPU and Memory Subsystem" section of the official Infineon datasheet (002-23185 Rev. *S). This frequency is achievable under 1.1 V core voltage with appropriate clock source configuration using the FLL or PLL; at 0.9 V, max frequency is reduced to 100 MHz per power-efficiency trade-off specifications.
Does CY8C6248AZI-S2D44 support execute-in-place (XIP) from external flash?
Yes - the Serial Memory Interface (SMIF) supports XIP from quad-SPI flash with hardware-accelerated on-the-fly AES-128 decryption and a dedicated 4 KB instruction cache. This enables direct code execution from external memory while maintaining security and power efficiency, as documented in Section 3.5.4 of the datasheet.
How many GPIO pins are available, and what advanced I/O features do they support?
CY8C6248AZI-S2D44 provides up to 102 programmable GPIOs, including six overvoltage-tolerant (OVT) pins and two Smart I/O ports (16 pins total) that perform Boolean logic autonomously during Deep Sleep. Each pin supports configurable drive strength, slew rate, and 21 programmable drive modes - verified in Section 3.6 and Table 6-11 of the datasheet.
Is the on-chip DC-DC buck converter enabled by default, and what is its quiescent current?
The on-chip DC-DC buck converter is disabled at power-on reset and must be explicitly enabled via register configuration (PWR_CTL_REG[DCDC_EN]). Its quiescent current is <1 µA in regulation mode, measured under typical conditions with light load - specified in Section 6.2.1 and validated in the "Power Supply Considerations" chapter of the datasheet.
