Product details
Overview
CY9AFB41NBPMC-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, 2.0 μs conversion), and LCD controller (40×8 SEG/COM). It operates at up to 40 MHz, supports six low-power modes, and targets embedded control in industrial HMIs and portable instrumentation.
For engineers reviewing the CY9AFB41NBPMC-G-JNE2 datasheet, CY9AFB41NBPMC-G-JNE2 pinout, CY9AFB41NBPMC-G-JNE2 application, or CY9AFB41NBPMC-G-JNE2 equivalent, key selection criteria include dual-bank Flash for seamless firmware updates, integrated USB host/device capability with endpoint buffering, real-time clock with date/time alarm, and 5 V-tolerant GPIO support on selected pins.
Technical Context
This MCU implements an ARM Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer for RTOS scheduling. Its memory subsystem includes two independent SRAM banks (SRAM0 for instruction/data, SRAM1 for system bus access) and dual-operation Flash enabling concurrent read-erase-write per bank.
The peripheral set integrates a full-featured USB 2.0 PHY with built-in PLL, HDMI-CEC/remote receiver (2 channels), CRC accelerator (CCITT CRC16 & IEEE-802.3 CRC32), and eight-channel DMA with burst/block/demand transfer modes - all accessible via configurable pin relocation to optimize PCB layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M3 r2p1, 40 MHz max operation - enables deterministic real-time task execution with low-latency interrupt handling. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports background firmware update without halting application code. |
| SRAM | 32 KB total: 16 KB SRAM0 (I/D bus), 16 KB SRAM1 (system bus) - isolates CPU instruction fetch from DMA/peripheral traffic. |
| ADC | 12-bit SAR, 24 channels, 2.0 μs conversion @ 2.7–3.6 V - meets sub-10 μs sampling requirements for motor current sensing or sensor fusion. |
| USB Interface | Full-Speed device/host, 6 endpoints (EP0–EP5), EP1 = 256-byte buffer - enables HID-class peripherals or USB-to-serial bridge functionality without external PHY. |
| Power Supply | 1.65–3.6 V (2.2–3.6 V with LCDC active, 3.0–3.6 V with USB active) - simplifies single-rail power design across mixed-peripheral use cases. |
| Low-Power Modes | Six modes including Deep Standby RTC/Stop with RAM retention options - extends battery life in always-on sensor nodes or remote controls. |
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 |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated analog/digital power pins enable clean separation of noise-sensitive ADC/LCDC domains from digital switching noise. |
| XTAL1/XTAL2 | Main clock oscillator input/output | Supports 4–48 MHz crystal or external clock source - critical for USB timing accuracy and system clock stability. |
| USB_DP/USB_DM | USB 2.0 differential data lines | Integrated transceiver eliminates need for external USB PHY; requires only series resistors and ESD protection diodes. |
| SEG0–SEG39, COM0–COM7 | LCD segment/com drive outputs | Direct drive of 40×8 segment LCD with internal bias resistor network - reduces BOM count for HMI displays. |
| PA0–PA15, PB0–PB15, etc. | Multi-function GPIO with port relocate | Peripheral function assignment can be remapped per pin - improves routing flexibility and avoids signal congestion on dense PCBs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash memory | Enables over-the-air firmware updates with zero downtime: one bank executes while the other is erased/written. |
| USB device/host dual mode | Single-chip solution for both peripheral attachment (e.g., USB HID keyboard) and host control (e.g., USB flash drive reader). |
| Hardware CRC accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation from CPU - reduces firmware overhead for communication integrity checks. |
| Port relocate function | Allows dynamic assignment of UART, I²C, CSIO, or timer outputs to any GPIO pin - decouples schematic design from physical layout constraints. |
| Deep Standby RTC mode | Maintains real-time clock and optional RAM retention using only sub-1 μA current from 32.768 kHz crystal - ideal for battery-backed timekeeping. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303VCT6 | ARM Cortex-M4F core, 256 KB Flash, no integrated USB PHY (requires external transceiver), no LCD controller | Targets motor control with FPU and advanced timers; lacks native LCD/CEC support | Select when floating-point math or high-resolution PWM is required over LCD/USB host capability |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4, 256 KB Flash, USB FS device-only, no USB host or HDMI-CEC, 16-bit ADC (1 Msps) | Focused on low-power connectivity (SCI/USB) but omits LCD driver and CEC hardware blocks | Choose for USB-CDC/DFU applications where LCD/CEC are unnecessary and higher ADC throughput is needed |
Compared with STM32F303VCT6 and RA4M1, CY9AFB41NBPMC-G-JNE2 uniquely integrates USB host/device, LCD controller, and HDMI-CEC in a single chip - reducing component count and board area for HMI and remote-control edge devices.

FAQ
Does CY9AFB41NBPMC-G-JNE2 support USB host functionality without external components?
Yes. The device integrates a full-speed USB 2.0 PHY with built-in PLL and supports host mode for Low/Full-Speed devices. Only standard USB termination resistors (15 kΩ pull-downs on D+/D−) and ESD protection diodes are required - no external transceiver or clock source is needed.
What is the maximum operating frequency of the ARM Cortex-M3 core in this MCU?
The CY9AFB41NBPMC-G-JNE2 operates the ARM Cortex-M3 core at up to 40 MHz, derived from the main PLL driven by an external 4–48 MHz crystal or oscillator. This frequency is validated across the full 1.65–3.6 V supply range and specified in the datasheet's AC characteristics section.
Can the LCD controller drive a 40×8 segment display without external bias circuitry?
Yes. The integrated LCD controller includes an internal dividing resistor network and dedicated bias voltage pins (VV0–VV4), enabling direct drive of 40-segment × 8-common multiplexed LCDs without external components - verified in the LCD Characteristics section of the datasheet.
How does the dual-bank Flash architecture improve firmware reliability during updates?
Dual-bank Flash allows one bank (e.g., upper 240 KB) to run active firmware while the other (lower 16 KB work area) is erased and reprogrammed. This enables atomic firmware updates with zero application interruption - critical for unattended industrial or medical devices where reset-based updates are unacceptable.
