Product details
Overview
CY9AFA42NBBGL-GE1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 256 KB dual-bank Flash, 32 KB SRAM (16 KB × 2 banks), and integrated LCD controller supporting up to 40×8 segments. It operates at up to 40 MHz, features hardware flow control on UART ch.4, and targets low-power embedded control in industrial HMI and consumer remote systems.
For engineers reviewing the CY9AFA42NBBGL-GE1 datasheet, CY9AFA42NBBGL-GE1 pinout, CY9AFA42NBBGL-GE1 application, or CY9AFA42NBBGL-GE1 equivalent, key selection criteria include dual-bank Flash for seamless firmware updates, 5 V-tolerant GPIOs on select pins, RTC with leap-year support, and HDMI-CEC/remote receiver capability for TV control subsystems.
Technical Context
This MCU implements the 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 dual-operation Flash (240 KB upper + 16 KB lower bank) enabling concurrent read-while-write, and two independent SRAM banks (SRAM0 on I/D-code bus, SRAM1 on system bus) for deterministic real-time access.
The peripheral set integrates an 8-channel DMA controller with 32-bit addressing, 24-channel 12-bit ADC with 2.0 μs conversion time at 2.7–3.6 V, and a programmable LCD controller with internal bias resistors and blinking function - all operating within 1.65–3.6 V supply range (2.2–3.6 V when LCDC active).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, up to 40 MHz - enables deterministic real-time execution with Thumb-2 instruction set and 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/data fetch from peripheral DMA traffic. |
| ADC | 24-channel 12-bit SAR, 2.0 μs conversion @ 2.7–3.6 V - meets fast-sampling requirements for motor current sensing or sensor fusion. |
| LCDC | 40 SEG × 8 COM, internal bias resistors, blinking function - drives segment-based displays in thermostats or appliance panels without external bias circuitry. |
| HDMI-CEC | Transmit/receive with automatic ACK, arbitration loss detection, and 1-byte block transmission - implements full CEC protocol stack in hardware for TV remote interoperability. |
| Low-Power Modes | Six modes including Deep Standby RTC with RAM retention - extends battery life in always-on remote control receivers or smart meter displays. |
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 with port relocate | Configurable as UART0/CSIO0/I²C0 pins; 5 V tolerant - enables flexible peripheral mapping and mixed-voltage interface design. |
| P10–P17 | General-purpose I/O with port relocate | Supports Base Timer ch.0–ch.3 and ADC ch.0–ch.7 - allows direct analog input routing and PWM output without PCB trace rework. |
| P20–P27 | General-purpose I/O with port relocate | Assigned to LCDC SEG0–SEG7 and HDMI-CEC ch.0 - integrates display driver and remote control functions on shared I/O bank. |
| P30–P37 | General-purpose I/O with port relocate | Supports UART ch.4 with RTS/CTS hardware flow control - enables reliable high-speed serial communication with external modems or Bluetooth modules. |
| VCC / VSS | Power supply / Ground | 1.65–3.6 V operation (2.2–3.6 V with LCDC active); separate analog/digital ground pins reduce noise coupling into ADC paths. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash memory | Enables over-the-air firmware updates with zero downtime: erase/write one bank while executing from the other. |
| Hardware HDMI-CEC engine | Offloads full CEC protocol processing (header generation, ACK reply, arbitration monitoring) from CPU, reducing firmware overhead by >70%. |
| Port relocate function | Allows dynamic assignment of UART/CSIO/I²C peripherals to any GPIO group (P0–P3), simplifying PCB layout and enabling last-minute interface changes. |
| RTC with leap-year correction | Maintains accurate calendar time across century boundaries without software intervention, critical for energy metering and HVAC scheduling. |
| Two independent SRAM banks | Prevents CPU-DMA contention: SRAM0 serves instruction/data cache, SRAM1 handles DMA buffers for ADC or UART transfers. |

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 |
|---|---|---|---|
| STM32F103VCT6 | 72 MHz Cortex-M3, 256 KB Flash, no integrated LCDC or HDMI-CEC; requires external bias for segment LCD. | Lacks native CEC/IR receiver; suitable for general-purpose control where display is driven by external controller. | Select when higher CPU speed is required and CEC/LCDC are handled externally. |
| RP2040 | Dual-core ARM Cortex-M0+, 2 MB Flash, no hardware CEC or LCDC; relies on PIO for bit-banged protocols. | No dedicated CEC engine or segment LCD driver; uses GPIO-based display multiplexing with higher CPU overhead. | Choose for cost-sensitive designs needing USB host/device but willing to implement CEC in software. |
Compared with STM32F103VCT6 and RP2040, CY9AFA42NBBGL-GE1 delivers integrated CEC and LCDC functionality that eliminates external ICs and reduces BOM count by 2–3 components in TV remote and appliance display applications.

FAQ
Does CY9AFA42NBBGL-GE1 support hardware flow control on all UART channels?
No. Hardware flow control (RTS/CTS) is supported only on UART channel 4, as confirmed in the FM3 Peripheral Manual and datasheet Rev. *D. Channels 0–3 lack dedicated RTS/CTS signal routing and must use software handshaking or external logic for flow management.
What is the maximum segment count supported by the integrated LCDC?
The LCDC supports up to 40 segment lines and 8 common lines (40×8), configurable in either 8-COM or 4-COM mode. This enables driving standard alphanumeric or custom segment displays found in thermostats, power tools, and home appliances without external drivers.
Is the 41-bit Unique ID accessible via standard debug interface?
Yes. The 41-bit factory-programmed unique ID is readable via the Serial Wire Debug (SWD) interface using standard CMSIS-DAP commands or Infineon's MemTool utility. It resides in a protected memory region and remains unchanged across firmware updates or resets.
Can the dual-bank Flash be used for secure boot validation?
Yes. The dual-bank architecture allows one bank to hold validated firmware while the other executes, enabling atomic firmware swaps and rollback protection. Combined with the CRC32 accelerator, it supports hardware-accelerated signature verification of the inactive bank before switching execution.
