Product details
Overview
CY9AF344NBBGL-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 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 supports six low-power modes including Deep Standby RTC and integrates HDMI-CEC/remote control receiver, RTC, and hardware CRC accelerator for embedded control applications in industrial HMI and smart appliance subsystems.
For engineers reviewing the CY9AF344NBBGL-GE1 datasheet, CY9AF344NBBGL-GE1 pinout, CY9AF344NBBGL-GE1 application, or CY9AF344NBBGL-GE1 equivalent, key selection criteria include dual-bank Flash execution capability, USB host/device coexistence, 5V-tolerant GPIO allocation via port relocate function, and sub-3.6 V operation with LVD1/LVD2 voltage monitoring.
Technical Context
The CY9AF344NBBGL-GE1 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 (240 KB upper + 16 KB lower bank) enabling concurrent read/erase/write operations, and two independent SRAM banks (SRAM0 on I/D-code bus, SRAM1 on system bus).
Peripheral integration includes a full-featured USB 2.0 controller with built-in PLL, eight-channel DMA with 32-bit addressing, multi-function serial interfaces (UART/CSIO/I²C across 8 channels), and dual watchdog timers - one hardware-based on 100 kHz CR oscillator active in all low-power modes except Deep Standby Stop/RTC.
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 firmware updates without halting execution via bank-swapping. |
| SRAM | 32 KB total: 16 KB SRAM0 (I/D-code bus), 16 KB SRAM1 (system bus) - isolates instruction/data access 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 and sensor fusion. |
| USB Interface | Full-Speed device/host with built-in PLL, 6 endpoints (EP0–EP5), double-buffered EP1–EP5 - enables embedded USB HID and MSC class implementations without external PHY. |
| Power Supply | VCC = 1.65–3.6 V; 3.0–3.6 V required for USB operation - supports wide-input battery-powered designs with USB connectivity only when rail is ≥3.0 V. |
| Low-Power Modes | Six modes including Deep Standby RTC/Stop with RAM retention option - extends battery life in always-on remote control receivers and metering applications. |
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; supports pull-up and direct level read; some pins 5V tolerant. |
| P10–P17 | General-purpose I/O with port relocate | Assignable to Base Timer ch.0–ch.3, HDMI-CEC0, or Remote Control Receiver; supports interrupt generation. |
| P20–P27 | General-purpose I/O with port relocate | Supports USB D+/D− (P20/P21), RTC crystal (P22/P23), and external bus address/data lines (P24–P27). |
| P30–P37 | General-purpose I/O with port relocate | Configurable as ADC input channels (P30–P37), UART1/CSIO1, or external interrupt sources (INT0–INT7). |
| VDD, VSS | Power supply and ground | Multiple VDD/VSS pairs ensure stable core/peripheral voltage distribution; decoupling required per datasheet layout guidelines. |
| CLKIN, CLKOUT | Main clock input/output | Accepts 4–48 MHz external crystal or oscillator; CLKOUT provides buffered main clock for trace/debug or system synchronization. |
| XTAL1, XTAL2 | Sub-clock crystal connection | Drives 32.768 kHz RTC crystal; enables accurate timekeeping and wake-up from Deep Standby RTC mode. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash memory | Enables seamless firmware update: erase/write one bank while executing from the other - critical for OTA-capable industrial controllers. |
| Port relocate function | Allows dynamic assignment of peripheral functions (e.g., UART, I²C, timer) to any GPIO group - simplifies PCB layout and reduces routing congestion. |
| Hardware CRC accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation from CPU - reduces data integrity check latency in USB/UART packet processing. |
| HDMI-CEC + Remote Control Receiver | Integrated dual-channel CEC transmitter/receiver and 4-byte IR buffer with repeat code detection - eliminates need for discrete CEC/IR ICs in AV equipment. |
| Two independent watchdogs | Hardware watchdog (100 kHz CR clock) remains active in all sleep modes except Deep Standby Stop/RTC - ensures fail-safe recovery in unattended systems. |
Applications
| Smart Appliance Control Panel | Industrial HMI Terminal |

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, 48 KB SRAM, no USB host, no HDMI-CEC, no port relocate | Lacks integrated CEC/IR receiver and USB host - requires external transceivers for full USB functionality | Select when higher CPU speed and larger SRAM are prioritized over CEC/USB host and low-power deep standby modes |
| RP2040 | Dual-core ARM Cortex-M0+, 2 MB Flash, 264 KB SRAM, USB 1.1 device-only, no RTC or CEC | No hardware RTC, no HDMI-CEC, no analog peripherals - unsuitable for time-critical or IR-controlled applications | Choose for cost-sensitive consumer devices where dual-core simplicity outweighs industrial-grade timing and control features |
Compared with STM32F103VCT6 and RP2040, CY9AF344NBBGL-GE1 uniquely combines USB host/device, HDMI-CEC, hardware RTC, and dual-bank Flash in a single 100-pin LQFP package - making it optimal for space-constrained, feature-rich embedded controllers requiring field-upgradable firmware and multi-protocol connectivity.

FAQ
Does CY9AF344NBBGL-GE1 support USB host mode with external device enumeration?
Yes. The integrated USB 2.0 Full/Low-speed host controller supports automatic detection of connected/disconnected USB devices, IN/OUT token handshake processing, and up to 256-byte packet length. It enumerates standard HID and MSC class devices without external PHY or hub ICs, verified per Infineon's FM3 USB Host Application Note AN95124.
What is the maximum operating frequency of the ARM Cortex-M3 core in CY9AF344NBBGL-GE1?
The CY9AF344NBBGL-GE1 operates its ARM Cortex-M3 core at up to 40 MHz, confirmed in Section 12.4.4 of datasheet 002-05635 Rev. *D. This frequency is achieved using the main PLL with either external 4–48 MHz clock or internal 4 MHz CR oscillator as input source.
Can the 24-channel ADC perform simultaneous sampling across multiple channels?
No. The 12-bit SAR ADC supports scanning and priority conversion modes but does not implement true simultaneous sampling. Conversion time per channel is fixed at 2.0 μs, and sequential scanning across up to 24 channels is managed by hardware FIFO with 16-step depth for scan mode.
Is the External Bus Interface available on CY9AF344NBBGL-GE1?
No. Per datasheet footnote on page 2, the External Bus Interface is explicitly excluded from CY9AF344LB variants - including CY9AF344NBBGL-GE1. This part supports only internal memory and peripheral interfacing via GPIO, serial interfaces, and USB.
