Product details
Overview
CY9AFA44NBPQC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with dual-bank flash (256 KB), 32 KB on-chip SRAM, integrated LCD controller (40×8 SEG/COM), 24-channel 12-bit ADC (2.0 μs conversion), and hardware flow control–enabled UART (ch.4). It targets low-power embedded control in industrial HMI, smart metering, and appliance panels.
For engineers reviewing the CY9AFA44NBPQC-G-JNE2 datasheet, CY9AFA44NBPQC-G-JNE2 pinout, CY9AFA44NBPQC-G-JNE2 application, or CY9AFA44NBPQC-G-JNE2 equivalent, key selection factors include its dual-operation flash architecture, 1.65–3.6 V supply range, RTC with leap-year support, HDMI-CEC transceiver capability, and absence of external bus interface - confirmed per Rev. *D datasheet.
Technical Context
This MCU implements the ARM Cortex-M3 r2p1 core at up to 40 MHz with NVIC supporting 48 peripheral interrupts and 16 priority levels. Its memory subsystem includes two independent SRAM banks (16 KB each) connected to I-code/D-code and system buses, enabling concurrent CPU and DMA access.
The peripheral set integrates a 40×8-segment LCD controller with internal bias resistors and blinking function, dual 12-bit ADC units with FIFO-based scanning and priority conversion, and an 8-channel DMA controller supporting byte/word transfers across 4 GB address space - all operating within six defined low-power modes including Deep Standby RTC with RAM retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time task scheduling with SysTick timer for OS integration. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports background erase/write during code execution. |
| SRAM | 32 KB total (16 KB SRAM0 + 16 KB SRAM1), split bus connection - allows parallel instruction fetch and data access without contention. |
| ADC | 24-channel 12-bit SAR, 2.0 μs conversion @ 2.7–3.6 V - meets sub-μs sampling requirements for motor current sensing and sensor fusion. |
| LCD Controller | 40 SEG × 8 COM, internal bias resistors, blinking function - drives segment-based displays without external voltage dividers or timing ICs. |
| Power Supply | 1.65–3.6 V (2.2–3.6 V when LCDC active) - compatible with single-cell Li-ion and multi-cell alkaline battery systems. |
| Low-Power Modes | Six modes including Deep Standby RTC with configurable RAM retention - achieves <1 μA RTC-only current for long-life battery operation. |
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 / Ground | Dedicated analog/digital power pins enable clean separation of noise-sensitive peripherals (ADC, LCDC) from digital logic. |
| P00–P07, P10–P17, etc. | General-purpose I/O with port relocate | 83 GPIOs support peripheral function remapping - simplifies PCB layout by decoupling signal routing from fixed pin assignments. |
| XTAL1 / XTAL2 | Main clock oscillator input/output | Supports 4–48 MHz crystal or external clock source - provides precise timing base for PLL and system clocks. |
| OSC32K / OSC32KOUT | Sub-clock oscillator input/output | Drives 32.768 kHz RTC and Watch Counter - enables accurate timekeeping and wake-up intervals up to 64 s. |
| VLCD / VV0–VV4 | LCD bias voltage supply | Internal resistor ladder generates LCD bias voltages - eliminates need for external voltage dividers in segment display designs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash Memory | Enables over-the-air firmware updates without halting application execution - critical for field-deployed industrial controllers. |
| HDMI-CEC Transceiver | Integrated header block auto-transmission and ACK generation - reduces host CPU overhead for consumer electronics remote control interoperability. |
| CRC Accelerator (CRC16/CRC32) | Offloads integrity checking from CPU - accelerates communication protocol validation (e.g., Modbus RTU, CAN FD payloads) by >10× vs. software CRC. |
| Hardware Watchdog (CR-clocked) | Remains active in Sleep, Timer, and RTC modes - ensures system recovery even during deep low-power states where main clock is stopped. |
| Port Relocate Function | Allows runtime assignment of UART, I²C, or CSIO to any GPIO group - increases design flexibility and simplifies board revision for signal routing changes. |

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 | Single-bank 256 KB Flash, no integrated LCDC or HDMI-CEC; 72 MHz Cortex-M3 core. | Lacks native segment LCD driver and CEC transceiver - requires external display controller and protocol stack. | Select when higher CPU performance is prioritized over integrated display/CEC and external components are acceptable. |
| RA4M1 (R7FA4M1AB3CFM) | 48 MHz Cortex-M4F core, 256 KB Flash, 32 KB SRAM, no LCDC; includes USB and CAN. | Offers floating-point unit and USB device interface but omits LCD bias generation and CEC hardware blocks. | Prefer when USB connectivity or DSP-intensive tasks (e.g., audio processing) outweigh segment display integration needs. |
Compared with STM32F103VCT6 and RA4M1, CY9AFA44NBPQC-G-JNE2 delivers unique value in cost-sensitive, display-centric embedded systems where integrated LCDC bias, HDMI-CEC transceiver, and dual-bank flash reduce BOM count and firmware development effort - without sacrificing ARM Cortex-M3 compatibility or low-power operation.

FAQ
Does CY9AFA44NBPQC-G-JNE2 support external memory expansion via parallel bus?
No. Unlike earlier CY9AA40NB variants such as CY9AFA41LB, this specific part (CY9AFA44NBPQC-G-JNE2) explicitly excludes External Bus Interface functionality per datasheet Rev. *D, Page 2. It relies solely on on-chip flash and SRAM for program and data storage.
What is the maximum operating frequency of the ARM Cortex-M3 core in this device?
The CY9AFA44NBPQC-G-JNE2 operates the ARM Cortex-M3 core at up to 40 MHz, as confirmed in the "Features" section of the official datasheet (Document Number 002-05633 Rev. *D). This frequency is achieved using the main PLL with either external crystal or internal high-speed CR oscillator input.
Is hardware flow control supported on all UART channels?
Hardware flow control (CTS/RTS) is supported only on UART channel 4, as stated in the datasheet footnote on Page 2. Channels 0–3 do not implement this feature, limiting automatic transmission control to a single dedicated serial interface.
How does the dual-bank flash architecture improve firmware update reliability?
Dual-bank flash allows one bank (e.g., upper 240 KB) to run active firmware while the other (lower 16 KB work area) is erased and rewritten - enabling atomic, fail-safe over-the-air updates without system interruption or external memory dependency.
