Product details
Overview
CY9AFB41MBBGL-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, 24-channel 12-bit ADC (2.0 µs conversion), and LCD controller supporting up to 40×8 segments. It operates at up to 40 MHz and supports six low-power modes including Deep Standby RTC.
For engineers reviewing the CY9AFB41MBBGL-GK9E1 datasheet, CY9AFB41MBBGL-GK9E1 pinout, CY9AFB41MBBGL-GK9E1 application, or CY9AFB41MBBGL-GK9E1 equivalent, key selection considerations include dual-bank Flash for seamless firmware updates, integrated USB PHY with built-in PLL, 100-pin LQFP package with 83 GPIOs (some 5 V tolerant), and hardware CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32.
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 on I/D-code bus, SRAM1 on system bus) and dual-operation Flash enabling concurrent read/erase/write per bank.
The peripheral set integrates a full-featured USB 2.0 transceiver with automatic endpoint buffer management, HDMI-CEC/remote control receiver with 4-byte buffer and repeat-code detection, and a programmable LCD controller with internal bias resistors and blinking support - all operating within 1.65–3.6 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M3 r2p1, up to 40 MHz - enables deterministic real-time execution with Thumb-2 instruction set and hardware divide. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports background erase/write for live firmware updates. |
| SRAM | 32 KB total (16 KB SRAM0 + 16 KB SRAM1), split bus architecture - isolates instruction/data access from system DMA traffic. |
| ADC | 24-channel 12-bit SAR, 2.0 µs conversion @ 2.7–3.6 V - meets sub-µs sampling requirements for motor current sensing or power monitoring. |
| USB Interface | Full-Speed device/host with built-in PLL, 6 endpoints (EP0–EP5), double-buffered EP1–EP5 - eliminates external PHY and clock synthesis components. |
| Low-Power Modes | Six modes including Deep Standby RTC (RAM retention optional) - enables <1 µA RTC-only operation using 32.768 kHz sub-clock. |
| CRC Accelerator | Hardware CCITT CRC16 and IEEE-802.3 CRC32 - offloads integrity checks from CPU during firmware OTA or communication stack processing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit ARM Cortex-M3 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103VET6 | 72 MHz Cortex-M3, 512 KB Flash, no integrated USB PHY or LCDC - requires external crystal and display driver. | Lacks native LCD and HDMI-CEC support - suitable only when those peripherals are omitted or implemented externally. | Select if higher CPU speed and larger Flash are prioritized over integrated display/CEC functionality. |
| RA4M1 (R7FA4M1AB3CFM) | 48 MHz Cortex-M4F, 256 KB Flash, USB FS device only (no host), no LCDC - includes TrustZone but no CEC/IR receiver. | Missing HDMI-CEC transmitter and remote control receiver - unsuitable for consumer IR/CEC bridging use cases. | Choose when floating-point math or security extensions outweigh need for CEC/IR integration. |
Compared with STM32F103VET6 and RA4M1, CY9AFB41MBBGL-GK9E1 uniquely combines USB device/host, LCD controller, and HDMI-CEC/IR receiver in a single 100-pin LQFP package - reducing system component count and PCB area for HMI and smart home edge nodes.

FAQ
Does CY9AFB41MBBGL-GK9E1 support USB host mode with external device enumeration?
Yes. The MCU implements a full USB 2.0 Full/Low-speed host controller with automatic device connect/disconnect detection, IN/OUT token handshake processing, and up to 256-byte packet support. It enumerates standard HID, mass storage, and CDC devices without external PHY or hub logic.
What is the maximum LCD resolution supported by the built-in LCDC?
The LCDC supports up to 40 segment lines and 8 common lines in multiplexed mode, enabling static or 1/2–1/8 bias displays. It includes internal voltage dividers and VV0–VV4 bias pins, allowing direct drive of segmented LCDs up to 320 pixels (40×8) without external bias generation circuitry.
Can the dual-bank Flash be used for secure firmware rollback?
Yes. Dual-bank architecture allows one bank to run active firmware while the other receives and validates a new image. Upon successful CRC check, the boot vector is redirected to the updated bank - enabling atomic, fail-safe firmware updates with guaranteed rollback to last-known-good version.
Is hardware flow control available on all UART channels?
No. Hardware flow control (CTS/RTS) is supported only on channel 4, as confirmed in the peripheral manual. Channels 0–3, 5–7 operate in UART mode without RTS/CTS signaling - requiring software handshaking or external logic for flow management on those interfaces.
