Overview
CY9BF404NABGL-GK6E1 from Infineon is a 32-bit ARM Cortex-M4F-based microcontroller with 1 MB flash, 192 KB SRAM, integrated USB 2.0 FS controller, and hardware crypto acceleration (AES-128/256, SHA-256, TRNG). It targets secure industrial control and IoT edge node applications requiring real-time processing and cryptographic integrity.
For engineers reviewing the CY9BF404NABGL-GK6E1 datasheet, CY9BF404NABGL-GK6E1 pinout, CY9BF404NABGL-GK6E1 application, or CY9BF404NABGL-GK6E1 equivalent, key selection criteria include flash endurance (100k write/erase cycles), operating voltage range (2.7–5.5 V), USB PHY integration, FPU support for deterministic floating-point math, and certified security features (PSA Level 2, SESIP Level 2).
Technical Context
This MCU implements a dual-bank flash architecture enabling read-while-write operation and seamless firmware updates. It integrates a 12-bit 1 Msps ADC with 16 channels, four 16-bit general-purpose timers, and a dedicated watchdog timer with windowed mode.
The device supports multiple low-power modes (DeepSleep, Hibernate, Stop) with wake-up latency under 5 µs from DeepSleep. Its clock system includes an internal 12 MHz RC oscillator, PLL with 200 MHz max CPU frequency, and programmable clock dividers for peripheral domain tuning.

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VIT6 | Higher CPU frequency (480 MHz), no PSA certification, lacks integrated USB PHY | Requires external USB transceiver; less suitable for certified secure boot deployments | Preferred when raw compute throughput outweighs security certification requirements |
| RA6M5GFP | Same PSA Level 2, lower flash (2 MB), no hardware TRNG, uses Renesas Secure Crypto Engine | Lacks true random number generation for key derivation; different crypto API abstraction layer | Chosen where Renesas ecosystem tooling and GUI framework integration are prioritized |
Compared with STM32H743VIT6 and RA6M5GFP, CY9BF404NABGL-GK6E1 uniquely combines PSA Level 2 certification, integrated USB PHY, and hardware TRNG in a single 100-pin LQFP package-enabling compact, certifiable, and USB-connected secure edge nodes without external components.

FAQ
What security certifications does CY9BF404NABGL-GK6E1 hold?
CY9BF404NABGL-GK6E1 is certified to PSA Certified Level 2 and SESIP Level 2. These cover secure boot with immutable root-of-trust, encrypted firmware updates, runtime attestation, and protection against side-channel and fault injection attacks. Certification documentation is published by Arm and GlobalPlatform, not embedded in the chip itself.
Does this MCU support USB device and host modes simultaneously?
No. CY9BF404NABGL-GK6E1 implements only USB 2.0 Full-Speed device mode with integrated PHY. It does not support USB host or OTG functionality. The USB controller supports CDC, HID, and MSC class drivers out of the box via Infineon's DAVE™ middleware.
Can the dual-bank flash be used for EEPROM emulation?
Yes. Infineon provides a certified EEPROM emulation library that leverages dual-bank flash to emulate 4–16 KB of wear-levelled non-volatile storage. It guarantees 100k write cycles per logical address and handles bank switching transparently during background writes.
What debug interfaces are supported?
The device supports SWD (Serial Wire Debug) via dedicated pins (SWDIO, SWCLK) and JTAG via TCK/TMS/TDI/TDO. SWD is recommended for production programming due to its 2-pin footprint and full debug capability. Both interfaces support breakpoints, watchpoints, and real-time memory access through standard tools like Segger J-Link and Infineon's MemTool.
