CY8C6247BZI-D54 Overview
PSoC 6 is a family of ultra-low-power 32-bit microcontrollers that combine an application processor and a low-power network/auxiliary processor, programmable analog and digital blocks (UDBs), and hardware-based security. It belongs to the broader taxonomy microcontroller -> 32-bit MCU -> ARM Cortex MCU -> PSoC 6 family -> wireless/secure connected (PSoC 64) sub-family, manufactured on a 40 nm low-power CMOS process for active and sleep current budgets suited to battery-powered IoT endpoints.
Key features include 1 MB (1M x 8) flash, 288 KB SRAM, hardware crypto accelerators, capacitive touch sensing (CAPSENSE™), USB, and a wide operating voltage range. According to the Infineon datasheet (PSoC 62 MCU family), the device supports multiple power modes down to deep-sleep currents in the microamp range, plus wake-on-interrupt for energy harvesting and battery applications. The 124-VFBGA package and dual-core architecture enable split-architecture firmware designs where the M4 handles application logic while the M0+ manages BLE stack, sensor fusion, or housekeeping.
Typical applications include wearables, smart home HMI panels, secure IoT endpoints, industrial HMI, and low-power wireless sensor hubs. The hardware crypto block makes it suitable for products needing secure boot, secure firmware update, and encrypted communication with users.
Design tip: when migrating from CY8C6247BZI-D34, recompile the firmware because the -D54 adds a hardware crypto block. The 124-VFBGA (9x9) footprint and pinout remain consistent with the -D34 in the same family, easing hardware reuse. Verified data via Infineon product page and DigiKey listing as of 2026-10-07.

Wearables & Fitness Trackers
The CY8C6247BZI-D54 dual-core architecture makes it ideal for wearables and fitness trackers, where the Cortex-M0+ always-on core handles BLE radio and sensor sampling at deep-sleep currents while the Cortex-M4F wakes for display and UI work. The 1 MB flash accommodates full FreeRTOS + GUI binaries, and the 288 KB SRAM fits display framebuffers. The hardware crypto block secures user health data, and the 124-VFBGA 9x9 mm footprint suits wrist-form PCBs.

Smart Home HMI Panels
For smart home HMI panels the CY8C6247BZI-D54 provides the responsive UI panel performance of the Cortex-M4F at 150 MHz and the always-on responsiveness of the M0+ core for capacitive touch sensing via CAPSENSE™. The wide 1.71-3.6 V supply range simplifies power design across battery-backed and mains-powered thermostats, and the 124-VFBGA 9x9 mm footprint enables compact panel enclosures with rich graphic interfaces.
Recommended
Secure IoT Endpoints
For secure IoT endpoints the CY8C6247BZI-D54 hardware crypto block accelerates AES, SHA, and TRNG operations for TLS handshakes and secure firmware updates. The Cortex-M0+ can run the network stack while the Cortex-M4F handles application logic, isolating security-critical code. The 1 MB flash accommodates encrypted OTA image storage alongside the active firmware, and the 1.71-3.6 V supply range enables coin-cell or Li-ion powered battery designs.
Recommended
Industrial HMI & Controls
For industrial HMI and control panels the CY8C6247BZI-D54 dual-core architecture isolates real-time control on the M0+ from HMI graphics on the M4F, simplifying IEC 61508 SIL-2 capable firmware partitioning. The 124-VFBGA package supports compact 9x9 mm layouts with multiple UART/SPI/I2C peripherals for PLC-style IO expansion. Hardware crypto secures factory-floor OTA updates over industrial Ethernet gateways.
Recommended
Low-Power Wireless Sensor Hubs
For low-power wireless sensor hubs the CY8C6247BZI-D54 deep-sleep currents in the microamp range per the PSoC 62 datasheet let the M0+ handle BLE beaconing or LoRa housekeeping while the M4F sleeps, achieving multi-year coin-cell life. The 288 KB SRAM fits sensor-fusion buffers and the 1 MB flash holds small RTOS + radio stack + application combined. The hardware crypto block secures sensor data at rest and in transit.
Recommended
Secure Payment & Access Control
For secure payment terminals and access control panels the CY8C6247BZI-D54 hardware crypto block performs PIN encryption and secure key storage while the Cortex-M4F handles the display, keypad, and NFC. The 1 MB flash fits full payment application stacks with secure boot, and the 288 KB SRAM supports biometric template buffers. The 1.71-3.6 V supply range simplifies battery-backed designs with USB-C charging.

Key Differentiators
- Hardware crypto block on-chip (vs CY8C6247BZI-D34)
- Pin-to-pin compatibility with -D44 variant (vs CY8C6247BZI-D44)
- Dual-core architecture with hardware crypto (vs Single-core PSoC 4 MCUs)
Design Notes
The CY8C6247BZI-D54 supports multiple low-power modes per the PSoC 62 datasheet, with deep-sleep currents in the microamp range. Use the Cortex-M0+ for always-on sensor polling and BLE housekeeping, keeping the Cortex-M4F in deep sleep until a wake event triggers application processing. Estimated: deep-sleep current ~5-10 uA for the auxiliary domain depending on RTC and retention RAM configuration.
The 124-VFBGA 9x9 package requires microvia PCB technology and 0.5 mm or finer pitch escape routing per Infineon design guidelines. Place 0.1 uF + 1 uF + 10 uF decoupling capacitor groups within 1 mm of each VDD/VSS pair, and route a continuous ground plane beneath the BGA to manage the dual-core switching currents. Use 4-layer stackup with dedicated power and ground layers.
When migrating from CY8C6247BZI-D34 to CY8C6247BZI-D54, recompile firmware because the JTAG ID and cyacd2 differ as noted in the Infineon community thread. The hardware crypto block presence changes peripheral identification, so libraries that auto-detect crypto capability will see different results. Verify that all third-party security middleware supports the -D54 variant before committing to a migration.
Compliance Information
