Product details
Overview
CY9AFB42NBBGL-GE1 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 SEG/COM). It operates up to 40 MHz, supports six low-power modes, and targets embedded control in industrial HMIs, metering, and appliance UIs.
For engineers reviewing the CY9AFB42NBBGL-GE1 datasheet, CY9AFB42NBBGL-GE1 pinout, CY9AFB42NBBGL-GE1 application, or CY9AFB42NBBGL-GE1 equivalent, key selection criteria include dual-bank Flash for safe firmware updates, integrated LCDC with internal bias resistors, USB host/device dual-role capability, and 5 V-tolerant GPIOs on selected pins.
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.
The peripheral set integrates a 24-channel 12-bit SAR ADC with scanning and priority conversion modes, an 8-channel DMA controller with burst/block/demand transfer support, and a programmable LCD controller with built-in voltage dividers and blinking control - all operating within 1.65–3.6 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M3 r2p1, 40 MHz max operation - enables deterministic real-time control with low-latency interrupt handling. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports simultaneous read/erase/write for robust OTA updates. |
| SRAM | 32 KB total: 16 KB SRAM0 (I/D bus), 16 KB SRAM1 (system bus) - enables parallel CPU execution and DMA transfers without contention. |
| USB Interface | Full-speed device/host dual-mode, 6 endpoints (EP0–EP5), EP1 = 256-byte buffer - allows embedded host capability for peripherals like HID devices or flash drives. |
| ADC | Two 12-bit SAR units, 24 channels, 2.0 μs conversion @ 2.7–3.6 V - delivers high-resolution analog sensing for motor control or energy monitoring. |
| LCDC | 40 SEG × 8 COM, internal bias resistor network, VV0–VV4 pins - eliminates external LCD bias components for cost-sensitive segment displays. |
| Low-Power Modes | Six modes including Deep Standby RTC/Stop with RAM retention options - extends battery life in portable or energy-harvested systems. |
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 |
|---|---|---|
| P00–P07 | General-purpose I/O port group 0 | 5 V-tolerant inputs; configurable as UART0 TX/RX, CSIO0, or I²C0 SCL/SDA via port relocate function. |
| P10–P17 | General-purpose I/O port group 1 | Supports HDMI-CEC0/1, Remote Control Receiver, and Base Timer channel 0–3 functions. |
| P20–P27 | General-purpose I/O port group 2 | Configurable for USB D+/D−, LCDC SEG0–SEG7, or ADC0 CH0–CH7 inputs. |
| P30–P37 | General-purpose I/O port group 3 | Supports LCDC COM0–COM7, UART1 TX/RX, and External Bus Interface address/data lines. |
| VCC, VSS | Power supply and ground | Multiple VCC/VSS pairs ensure stable core and I/O domain operation; decoupling required per datasheet layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash memory | Enables background firmware update: one bank executes while the other is erased/written - critical for fail-safe field upgrades. |
| Integrated LCDC with internal bias | Eliminates need for external resistor ladder or charge pump - reduces BOM count and PCB area for 40×8 segment displays. |
| USB device/host dual-mode | Allows single MCU to act as USB peripheral (e.g., HID keyboard) or host (e.g., reading USB mass storage) - simplifies system architecture. |
| Port relocate function | Permits dynamic assignment of peripheral functions (UART, I²C, CSIO) to any GPIO group - increases board layout flexibility and reuse. |
| Hardware watchdog + software watchdog | Dual independent watchdogs: hardware WD runs on 100 kHz CR oscillator during deep sleep; software WD uses main clock - ensures reliability across all power modes. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103VET6 | ARM Cortex-M3, 512 KB Flash, 64 KB SRAM, no integrated LCDC or HDMI-CEC; USB only device mode. | Lacks native segment LCD driver and CEC protocol engine - requires external display controller or discrete IR decoder. | Select when higher Flash/SRAM capacity is needed and LCDC/CEC are implemented externally. |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4F, 256 KB Flash, 32 KB SRAM, no LCDC, no HDMI-CEC; includes capacitive touch sensing. | Offers floating-point unit and touch IP but omits LCD bias and CEC hardware - suited for capacitive UIs over segment displays. | Select for touch-based interfaces where segment LCD and IR/CEC are not required. |
Compared with STM32F103VET6 and RA4M1, CY9AFB42NBBGL-GE1 uniquely integrates LCDC with internal bias and HDMI-CEC transceiver - reducing component count and firmware complexity for segment-display and consumer electronics control applications.

FAQ
What power supply voltage ranges does CY9AFB42NBBGL-GE1 support?
The device operates from 1.65 V to 3.6 V across all modes. When USB functionality is active, VCC must be 3.0–3.6 V; when LCDC is used, minimum VCC is 2.2 V. These ranges are validated per datasheet Section 13.2 and enable flexible power architecture design in battery- and line-powered systems.
Does CY9AFB42NBBGL-GE1 support hardware flow control on its UART interfaces?
Yes - hardware flow control (CTS/RTS) is supported exclusively on channel 4 of the multi-function serial interface, as confirmed in Section 4.2 of the datasheet. Channels 0–3 and 5–7 do not implement this feature, limiting full-duplex handshaking to a single UART instance.
Can the internal CRC accelerator compute custom polynomials beyond CCITT CRC16 and IEEE-802.3 CRC32?
No - the hardware CRC accelerator is fixed to CCITT CRC16 (0x1021) and IEEE-802.3 CRC32 (0x04C11DB7) polynomials only. Custom polynomial computation must be performed in software using the general-purpose CPU, as stated in Section 18.3 of the FM3 Peripheral Manual.
Is the 41-bit Unique ID accessible via standard debug interface or only through firmware?
The 41-bit unique ID is readable only by firmware executing on the device - it resides in a dedicated ROM register (UIDR) and is not exposed through SWJ-DP debug access. This design prevents unauthorized extraction during programming or testing, aligning with Infineon's secure identity management policy.
