Product details
Overview
CY9AF344NBPMC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 256 KB dual-bank Flash, 32 KB on-chip SRAM (16 KB SRAM0 + 16 KB SRAM1), USB 2.0 Full-Speed device/host interface, and 24-channel 12-bit ADC operating in 2.0 μs conversion time. It targets embedded motor control and industrial HMI applications requiring low-power operation down to Deep Standby RTC mode and real-time peripheral coordination.
For engineers reviewing the CY9AF344NBPMC-G-JNE2 datasheet, CY9AF344NBPMC-G-JNE2 pinout, CY9AF344NBPMC-G-JNE2 application, or CY9AF344NBPMC-G-JNE2 equivalent, key selection criteria include dual-bank Flash for seamless firmware updates, USB host/device dual-role capability, hardware flow control on UART ch.4, HDMI-CEC/remote receiver support, and 83 GPIOs with port relocation in 100-pin LQFP package.
Technical Context
This MCU implements an ARM Cortex-M3 r2p1 core running at up to 40 MHz with integrated NVIC supporting 48 peripheral interrupts and 16 priority levels. Its memory subsystem includes dual-operation Flash enabling concurrent read-erase-write across upper (240 KB) and lower (16 KB main + 32 KB work) banks, plus two independent SRAM blocks optimized for instruction/data (SRAM0) and system bus (SRAM1) access.
The peripheral set is built for deterministic real-time control: eight base timers support PWM, PPG, reload, and PWC modes; dual 32/16-bit down counters provide precise interval timing; and the 8-channel DMA controller operates on a dedicated bus to offload CPU bandwidth during high-throughput transfers from ADC, UART, or USB endpoints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time task scheduling with 24-bit SysTick timer for OS integration. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower main + 32 KB lower work) - supports background firmware update without halting execution. |
| SRAM | 32 KB total (16 KB SRAM0 on I/D bus + 16 KB SRAM1 on system bus) - separates instruction/data caching from peripheral buffer storage. |
| ADC | 24-channel 12-bit SAR, 2.0 μs conversion @ 2.7–3.6 V - meets fast-sampling requirements for motor current sensing and sensor fusion. |
| USB Interface | Full-Speed device/host with 6 endpoints (EP0–EP5), EP1 double-buffered to 256 bytes - enables HID-class peripherals and host-side USB flash drive control. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dual power domains: VCC = 1.65–3.6 V (3.0–3.6 V required for USB operation); separate analog/digital ground routing recommended. |
| XTAL1/XTAL2 | Main clock oscillator input/output | Supports 4–48 MHz crystal or external clock source; drives PLL for CPU and USB clock generation. |
| RTCXTAL1/RTCXTAL2 | Real-time clock oscillator | 32.768 kHz crystal connection for RTC and Watch Counter; enables wake-up from Stop/Deep Standby modes. |
| USB_DP/USB_DM | USB 2.0 Full-Speed differential pair | Integrated transceiver with internal pull-up on USB_DP; requires external 1.5 kΩ pull-up for device enumeration. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O with multiplexing | 83 total GPIOs; port relocate function allows dynamic assignment of UART/CSIO/I²C functions to configurable pins. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash architecture | Enables over-the-air firmware updates with zero downtime: erase/write one bank while executing from the other. |
| USB dual-role controller | Reduces BOM count in HMI systems by supporting both device (e.g., USB HID keyboard) and host (e.g., USB mass storage) roles in same silicon. |
| HDMI-CEC + remote receiver | Integrates consumer electronics control protocol and IR demodulation in single chip - eliminates discrete CEC transceivers and IR receivers. |
| Hardware UART flow control (ch.4) | Automated RTS/CTS handshake prevents data loss in high-speed serial communication with modems or industrial sensors. |
| CRC accelerator (CRC16/CRC32) | Offloads integrity checking from CPU during firmware OTA validation or secure boot signature verification. |

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 USB host, no HDMI-CEC, no hardware UART flow control | Lacks integrated CEC/IR receiver and USB host - requires external components for smart home hub use cases | Select when USB device-only and higher CPU speed are prioritized over protocol integration. |
| RP2040 | Dual-core ARM Cortex-M0+, 2 MB Flash, USB device/host, no CEC/IR, no hardware flow control, no analog comparator | No native HDMI-CEC or remote receiver; lacks 12-bit ADC with FIFO and scanning mode for sensor arrays | Prefer for cost-sensitive, high-flash IoT edge nodes where CEC/IR and precision ADC are not required. |
Compared with STM32F103VCT6 and RP2040, CY9AF344NBPMC-G-JNE2 uniquely integrates HDMI-CEC transmitter/receiver, IR remote decoder, hardware UART flow control, and dual-bank Flash-making it optimal for consolidated consumer electronics control and industrial HMI where protocol offload and firmware update resilience are critical.

FAQ
What power supply voltage range does CY9AF344NBPMC-G-JNE2 support?
The device operates from 1.65 V to 3.6 V on VCC. When USB functionality is used, VCC must be maintained between 3.0 V and 3.6 V to ensure proper USB transceiver operation and compliance with Full-Speed signaling requirements per USB 2.0 specification.
Does CY9AF344NBPMC-G-JNE2 support simultaneous USB device and host operation?
No - the USB interface supports device mode and host mode, but not concurrently. Mode selection is configured at initialization via software register settings; switching requires reinitialization of the USB controller and associated endpoints.
How many GPIO pins are available in the 100-pin LQFP package?
The CY9AF344NBPMC-G-JNE2 provides up to 83 general-purpose I/O pins in the 100-pin LQFP package. Some pins are 5V-tolerant and designated for specific peripheral functions such as UART, CSIO, I²C, or external bus interface, with port relocation enabling flexible peripheral pin mapping.
What is the purpose of the dual-bank Flash architecture?
Dual-bank Flash allows independent erase, write, and read operations on upper (240 KB) and lower (16 KB main + 32 KB work) banks. This enables background firmware updates - for example, downloading new code to one bank while executing from the other - eliminating system downtime during field upgrades.
