Product details
Overview
CY9AFA41MBPMC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 256 KB dual-bank Flash (240 KB upper + 16 KB lower), 32 KB on-chip SRAM (16 KB SRAM0 + 16 KB SRAM1), and integrated peripherals including LCD controller (40×8 SEG/COM), 24-channel 12-bit ADC (2.0 μs conversion), and 8-channel DMA. It operates at up to 40 MHz and supports six low-power modes, targeting embedded control in industrial HMI and appliance panels.
For engineers reviewing the CY9AFA41MBPMC-G-JNE2 datasheet, CY9AFA41MBPMC-G-JNE2 pinout, CY9AFA41MBPMC-G-JNE2 application, or CY9AFA41MBPMC-G-JNE2 equivalent, key selection criteria include dual-bank Flash for seamless firmware updates, 5 V-tolerant GPIOs on selected pins, RTC with leap-year support, HDMI-CEC transceiver capability, and SWJ-DP debug interface compatibility.
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 features independent I-code/D-code buses for SRAM0 and system bus for SRAM1, enabling concurrent CPU and DMA access without contention.
The peripheral set includes a programmable LCD controller with internal bias resistors and blinking function, eight base timers configurable as PWM/PPG/reload/PWC, and two watchdogs - one hardware-based on the 100 kHz CR oscillator for deep-sleep supervision, and one software-controllable.
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 low-latency interrupt handling. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports background erase/write for live firmware updates without halting execution. |

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 and reprogrammed. |
| HDMI-CEC transceiver | Integrated CEC protocol engine with automatic header transmission, ACK reply, and arbitration loss detection - reduces host CPU overhead in TV/AV system control. |
| Two independent watchdogs | Hardware watchdog (100 kHz CR clock) remains active in all low-power modes except Deep Standby Stop/RTC - guarantees fail-safe recovery even during ultra-low-power operation. |
| CRC accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation from CPU - accelerates integrity checks for communication buffers and flash data verification. |
| Port relocate function | Allows runtime assignment of peripheral functions (UART, I²C, CSIO) to alternative GPIO pins - increases board design flexibility and simplifies routing congestion fixes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY9AA40NBPMC-G-JNE2 | Same FM3 family, identical package and pinout, but lacks HDMI-CEC and Remote Control Receiver blocks. | No CEC/IR support limits use in AV remote designs; otherwise matches for general HMI and control. | Select when CEC/IR functionality is unnecessary and cost optimization is critical. |
| FM3-160R-01 | Successor series with enhanced security (TRNG, AES), higher Flash (512 KB), and updated peripheral set; not pin-compatible. | Requires PCB redesign and firmware adaptation; suited for new designs needing cryptographic services or extended memory. | Choose for next-generation products requiring secure boot or larger code footprint, not drop-in replacement. |
Compared with CY9AA40NBPMC-G-JNE2 and FM3-160R-01, CY9AFA41MBPMC-G-JNE2 uniquely balances legacy peripheral integration (CEC, LCDC, dual-bank Flash) with proven industrial qualification and long-term supply continuity - making it optimal for sustaining existing appliance and HMI platforms.

FAQ
What is the maximum operating frequency and supported voltage range for CY9AFA41MBPMC-G-JNE2?
The CY9AFA41MBPMC-G-JNE2 operates at up to 40 MHz with a supply voltage range of 1.65 V to 3.6 V. When the LCD controller is active, the minimum VCC is raised to 2.2 V to ensure stable bias generation and segment drive performance across temperature and process variation.
Does this MCU support in-application programming (IAP) using dual-bank Flash?
Yes. The dual-bank Flash architecture (240 KB upper + 16 KB lower) allows simultaneous read from one bank while erasing or programming the other. This enables robust IAP for firmware updates without halting real-time tasks or requiring external memory.
Which debug interface does CY9AFA41MBPMC-G-JNE2 provide, and is ETM supported?
The device supports Serial Wire JTAG Debug Port (SWJ-DP) for full debug and programming access. Embedded Trace Macrocell (ETM) is not supported on this variant - only SWJ-DP is implemented, as confirmed in the FM3 Peripheral Manual TYPE6 classification and datasheet revision notes.
How many LCD segments and commons can be driven, and what bias configuration is supported?
The integrated LCDC supports up to 40 segments and 8 commons, with selectable 4- or 8-COM operation. It includes internal dividing resistors and dedicated VV0–VV4 bias pins, enabling direct connection to static or multiplexed LCD glass without external resistor networks or charge pumps.
