Product details
Overview
CY9AFB41NBPQC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 256 KB dual-bank Flash, 32 KB SRAM, USB 2.0 Full-Speed device/host interface, 12-bit ADC (24 channels), and LCD controller (40×8). It operates at up to 40 MHz, supports six low-power modes, and targets embedded control in industrial HMI, sensor nodes, and USB-connected peripherals.
For engineers reviewing the CY9AFB41NBPQC-G-JNE2 datasheet, CY9AFB41NBPQC-G-JNE2 pinout, CY9AFB41NBPQC-G-JNE2 application, or CY9AFB41NBPQC-G-JNE2 equivalent, key selection criteria include dual-bank Flash for safe firmware updates, integrated USB host/device capability, 5 V-tolerant GPIOs on selected pins, RTC with calendar support, and hardware CRC acceleration for data integrity.
Technical Context
This MCU implements the ARM Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels. Its memory subsystem includes two independent SRAM banks (SRAM0/SRAM1) connected to I-code/D-code and system buses respectively, enabling concurrent CPU and DMA access without contention.
The peripheral set integrates a full-featured USB 2.0 transceiver with built-in PLL, HDMI-CEC/remote receiver (2 channels), LCDC with internal bias resistors, and eight-channel DMA supporting byte/half-word/word transfers across 4 GB address space - all optimized for deterministic real-time control in resource-constrained embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M3 r2p1, 40 MHz max operation - enables deterministic real-time task scheduling with low-latency interrupt response. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports simultaneous erase/write/read for robust over-the-air firmware updates. |
| SRAM | 32 KB total: 16 KB SRAM0 (I/D bus), 16 KB SRAM1 (system bus) - allows parallel CPU instruction fetch and DMA data movement. |
| USB Interface | Full-Speed device/host with built-in PLL, 6 endpoints (EP0–EP5), double-buffered EP1–EP5 - eliminates external clock synthesis and enables plug-and-play connectivity. |
| ADC | Two 12-bit SAR units, 24 channels, 2.0 μs conversion @ 2.7–3.6 V - delivers high-speed analog sensing for motor control or environmental monitoring. |
| Low-Power Modes | Six modes including Deep Standby RTC/Stop with RAM retention options - extends battery life in always-on sensor or timer applications. |
| Operating Voltage | 1.65–3.6 V (2.2–3.6 V for LCDC, 3.0–3.6 V for USB) - supports wide-input power supplies while maintaining peripheral functionality. |
Pinout & Package
Package: 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash memory | Enables background firmware update: one bank executes while the other is erased/written, eliminating application downtime. |
| Hardware CRC accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation from CPU, reducing latency in communication and storage integrity checks. |
| Port relocate function | Allows dynamic remapping of peripheral functions (UART, I²C, CSIO) to alternate GPIO pins, increasing PCB layout flexibility and design reuse. |
| 5 V-tolerant GPIOs | Selected pins tolerate 5 V logic inputs even when VCC = 1.65–3.6 V, simplifying interface with legacy 5 V peripherals without level shifters. |
| Embedded Trace Macrocell (ETM) | Provides non-intrusive instruction trace for real-time debugging and performance profiling without halting CPU execution. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103VCT6 | ARM Cortex-M3, 256 KB Flash, 48 KB SRAM, no integrated USB PHY or LCDC - requires external USB transceiver and display driver. | Lacks native LCD and USB device/host PHY; better suited for cost-sensitive designs where those peripherals are omitted or implemented externally. | Select when USB/LCD integration is unnecessary and higher SRAM headroom is prioritized over peripheral integration. |
| RA4M1 (R7FA4M1AB3CFP) | ARM Cortex-M4F, 256 KB Flash, 32 KB SRAM, USB FS device only (no host), no LCDC - adds FPU but omits HDMI-CEC and segment LCD driver. | Targets USB-only connectivity with floating-point math; unsuitable for standalone LCD or CEC-based remote control systems. | Choose for signal processing workloads requiring FPU, where USB device-only and no LCD/CEC suffices. |
Compared with STM32F103VCT6 and RA4M1, CY9AFB41NBPQC-G-JNE2 uniquely combines USB device/host PHY, 40×8 segment LCD driver, HDMI-CEC, and dual-bank Flash in a single 100-pin LQFP package - delivering highest peripheral integration for compact HMI and remote-control embedded systems.

FAQ
What power supply configurations does CY9AFB41NBPQC-G-JNE2 support?
The MCU operates from 1.65 V to 3.6 V on VCC. When USB functionality is used, VCC must be 3.0–3.6 V; for LCD operation, VCC must be 2.2–3.6 V. The device includes dual-stage Low-Voltage Detection (LVD1/LVD2) with configurable thresholds and interrupt/reset outputs for brown-out protection.
Does CY9AFB41NBPQC-G-JNE2 support debug interfaces beyond SWD?
Yes - it features Serial Wire JTAG Debug Port (SWJ-DP) and Embedded Trace Macrocell (ETM) for real-time instruction trace. Unlike some FM3 variants, this part supports ETM, enabling non-intrusive code profiling and timing analysis without halting CPU execution during debugging.
Can the USB interface operate in both device and host modes simultaneously?
No - USB device and host modes are mutually exclusive and configured at runtime via software. The hardware supports either mode, but not concurrent operation. Switching requires reinitialization of the USB controller and associated endpoints, making it suitable for applications that alternate roles (e.g., firmware update via device mode, then data collection via host mode).
How is the dual-bank Flash memory managed during firmware updates?
Firmware updates use bank-swapping: new code is written to the inactive bank while the active bank continues execution. Upon successful verification, the boot vector is redirected to the updated bank via BOOT register settings. This ensures zero-downtime field upgrades and rollback capability if corruption occurs.
