Product details
Overview
CY9AFB41NBBGL-GK9E1 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 supporting up to 40×8 segments. It operates from 1.65–3.6 V and targets low-power embedded control in industrial HMI and metering systems.
For engineers reviewing the CY9AFB41NBBGL-GK9E1 datasheet, CY9AFB41NBBGL-GK9E1 pinout, CY9AFB41NBBGL-GK9E1 application, or CY9AFB41NBBGL-GK9E1 equivalent, key selection factors include dual-bank Flash execution capability, integrated USB PHY with built-in PLL, RTC with leap-year support, HDMI-CEC/remote receiver dual-channel support, and six low-power modes including Deep Standby RTC with RAM retention.
Technical Context
The CY9AFB41NBBGL-GK9E1 implements an ARM Cortex-M3 r2p1 core running at up to 40 MHz with NVIC supporting 48 peripheral interrupts and 16 priority levels. Its memory subsystem includes dual-bank Flash enabling concurrent read/erase/write operations and two independent SRAM banks (SRAM0 for I/D-code, SRAM1 for system bus).
Peripherals are tightly coupled to the core via dedicated buses: DMA controller (8 channels, 32-bit addressing) operates independently of CPU; USB interface integrates both device and host controllers with automatic token handshake and endpoint double buffering; LCDC supports 40 SEG × 8 COM with internal bias resistors and blinking control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time task scheduling with hardware divide and Thumb-2 instruction set. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state - allows background firmware updates without halting execution. |
| SRAM | 32 KB total (16 KB SRAM0 + 16 KB SRAM1), split I/D and system bus - reduces core-memory contention during interrupt-heavy operation. |
| ADC | 12-bit SAR, 24 channels, 2.0 µs conversion @ 2.7–3.6 V - supports high-speed sensor sampling in motor control or energy metering. |
| USB Interface | Full-Speed device/host, 6 endpoints (EP0–EP5), built-in PLL - eliminates need for external crystal or clock generator in USB-connected devices. |
| Low-Power Modes | Six modes including Deep Standby RTC with RAM retention - enables battery-backed timekeeping and wake-on-event in portable equipment. |
| LCDC | 40 SEG × 8 COM, internal bias resistors, VV0–VV4 pins - drives segment-based displays without external voltage dividers or charge pumps. |
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 | Dual VCC domains (core/analog) with separate VSS return paths reduce noise coupling into ADC and RTC circuits. |
| XTALIN/XTALOUT | Main clock oscillator input/output | Supports 4–48 MHz crystal or external clock source; required for USB PLL and high-precision timing. |
| OSC32IN/OSC32OUT | Sub-clock oscillator input/output | Connects to 32.768 kHz crystal for RTC and low-power timer operation during Stop/Deep Standby modes. |
| USB_DP/USB_DM | USB 2.0 Full-Speed differential pair | Integrated transceiver with on-die termination - no external resistors needed for USB device enumeration. |
| SEG0–SEG39, COM0–COM7 | LCD segment/com common drivers | Direct drive of passive LCD glass; internal resistor ladder sets bias voltage without external components. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O with port relocate | Flexible peripheral mapping (UART/CSIO/I²C/ADC) per pin via register configuration - simplifies PCB layout reuse across variants. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash memory | Enables over-the-air firmware updates while maintaining active application execution in the opposite bank. |
| USB device/host with built-in PLL | Eliminates external 48 MHz crystal and reduces BOM count for USB-enabled human interface devices. |
| HDMI-CEC and remote control receiver (2 ch) | Allows single-chip implementation of TV remote control decoding and CEC command transmission in smart appliances. |
| Real-time clock with leap-year support | Maintains accurate calendar time across decades without host software intervention or periodic correction. |
| CRC accelerator (CRC16/CRC32) | Offloads integrity checking from CPU during firmware update verification or communication protocol validation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103RCT6 | ARM Cortex-M3, 256 KB Flash, 48 MHz, no integrated USB PHY or LCDC - requires external transceiver and display driver. | Lacks native segment LCD drive and HDMI-CEC; better suited for general-purpose control where USB is host-only or LCD is graphical. | Select when USB host functionality dominates and display is OLED/TFT with SPI interface. |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4F, 256 KB Flash, 48 MHz, integrated USB FS PHY, no LCDC - adds FPU but omits segment LCD and CEC peripherals. | Superior DSP performance for motor control, but missing CEC/remote receiver and analog LCD bias generation. | Prefer for sensor fusion or closed-loop control where floating-point math outweighs display/CEC requirements. |
Compared with STM32F103RCT6 and RA4M1, CY9AFB41NBBGL-GK9E1 uniquely integrates segment LCD drive, HDMI-CEC transceiver, and dual-bank Flash in a single 100-pin LQFP package - reducing bill-of-materials and firmware complexity for appliance HMI and metering designs requiring calendar-aware RTC and field-upgradable code.

FAQ
Does CY9AFB41NBBGL-GK9E1 support USB device and host simultaneously?
No. The USB interface supports device mode and host mode, but not simultaneous dual-role operation. Device mode uses endpoints EP0–EP5 with double buffering; host mode supports up to two connected devices with automatic IN/OUT token handling and wake-up detection. Mode selection is configured at initialization via USB control registers.
What is the maximum operating frequency of the ARM Cortex-M3 core?
The CY9AFB41NBBGL-GK9E1 core runs at up to 40 MHz, derived from the main clock (4–48 MHz) via the main PLL. This frequency is confirmed in the datasheet's "Recommended Operating Conditions" section and validated across voltage ranges 1.65–3.6 V. Higher frequencies are not supported due to silicon characterization limits.
Can the LCD controller drive dot-matrix displays?
No. The LCDC is designed exclusively for static or multiplexed segment-type LCDs (up to 40 SEG × 8 COM). It lacks the frame buffer, timing generators, and pixel clock circuitry required for dot-matrix or graphic LCDs. Driving such displays would require external controller or FPGA assistance.
Is the 41-bit Unique ID accessible via standard debug interface?
Yes. The 41-bit device-unique identifier is readable via the SWJ-DP debug port using standard ARM CoreSight protocols. It resides in a dedicated system control register (SYSCFG_UIDR) and is accessible in both debug and runtime modes without requiring special unlock sequences or privilege escalation.
