Product details
Overview
CY9AF144LBQN-G-AVE2 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), and operation up to 40 MHz. It integrates UART/CSIO/I²C interfaces, 24-channel 12-bit ADC (2.0 µs conversion), RTC, HDMI-CEC, and six low-power modes - deployed in industrial motor control and smart sensor nodes requiring deterministic real-time response.
For engineers reviewing the CY9AF144LBQN-G-AVE2 datasheet, CY9AF144LBQN-G-AVE2 pinout, CY9AF144LBQN-G-AVE2 application, or CY9AF144LBQN-G-AVE2 equivalent, key selection criteria include dual-bank Flash execution-in-place capability, 5 V-tolerant GPIO support on selected pins, hardware CRC acceleration (CRC16/CRC32), and SWJ-DP debug interface without ETM.
Technical Context
This MCU implements the ARM Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels. Its memory subsystem features independent I-code/D-code buses for SRAM0 and system bus for SRAM1, enabling concurrent instruction fetch and data access.
The peripheral set includes eight base timers (configurable as PWM/PPG/reload/PWC), dual watchdogs (hardware clocked by 100 kHz CR oscillator), and a DMA controller with 8 channels supporting byte/half-word/word transfers across 4 GB address space - all operating independently of CPU cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time task scheduling with 24-bit SysTick timer. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports simultaneous erase/write/read per bank for firmware updates without halting execution. |
| SRAM | 32 KB total: 16 KB SRAM0 (I/D bus), 16 KB SRAM1 (system bus) - isolates critical code/data paths from peripheral DMA traffic. |
| ADC | 24-channel 12-bit SAR, 2.0 µs conversion @ 2.7–3.6 V - meets sub-µs sampling requirements for closed-loop motor current sensing. |
| Low-Power Modes | Six modes including Deep Standby RTC/Stop with RAM retention - extends battery life in wireless sensor endpoints to >5 years on coin cell. |
| Debug Interface | Serial Wire JTAG Debug Port (SWJ-DP), no ETM - provides full breakpoint/watchpoint capability with minimal pin count (SWDIO/SWCLK/nRESET). |
| Supply Voltage | 1.65 V to 3.6 V - compatible with single-cell Li-ion, 3.3 V logic rails, and energy-harvesting power sources. |
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 domains with separate decoupling - required for ADC noise immunity and stable PLL operation. |
| XTAL / EXTAL | Main crystal oscillator input/output | Supports 4–48 MHz external crystals - used for high-accuracy timing in communication peripherals and RTC calibration. |
| OSC32K / OSC32KOUT | 32.768 kHz sub-clock input/output | Drives RTC and wake-up timers in Stop/Deep Standby modes - enables calendar timekeeping during ultra-low-power states. |
| PA0–PA15, PB0–PB15, etc. | Multi-function GPIO | Up to 83 fast I/O ports with port relocate function and per-pin pull-up - allows flexible PCB layout and peripheral remapping without hardware changes. |
| SWDIO / SWCLK / nRESET | Debug interface signals | Standard ARM Serial Wire Debug interface - enables in-circuit programming and real-time trace without dedicated JTAG pins. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash memory | Enables background firmware update: execute from upper bank while writing lower bank - eliminates system downtime during field upgrades. |
| Hardware CRC accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation - reduces CPU load by >90% for secure OTA packet validation and flash integrity checks. |
| HDMI-CEC transceiver | Integrated header block generation, ACK auto-reply, and arbitration loss detection - eliminates external CEC PHY for TV remote control integration. |
| 5 V-tolerant I/O pins | Selected GPIOs withstand 5 V inputs while powered at 3.3 V - simplifies interfacing with legacy 5 V peripherals without level shifters. |
| Two independent watchdogs | Hardware watchdog (100 kHz CR clock) remains active in all sleep modes except Deep Standby RTC/Stop - ensures fail-safe recovery even during extended low-power operation. |

FAQ
Does CY9AF144LBQN-G-AVE2 support external memory expansion?
No. Unlike earlier CY9A140NB variants such as CY9AF141LB, the CY9AF144LBQN-G-AVE2 explicitly omits External Bus Interface support per the official datasheet (Rev. *D, Page 2). It relies solely on on-chip Flash and SRAM, eliminating external NOR Flash or SRAM connections but reducing BOM complexity and PCB area.
What debug capabilities does CY9AF144LBQN-G-AVE2 provide?
CY9AF144LBQN-G-AVE2 supports Serial Wire JTAG Debug Port (SWJ-DP) only - no Embedded Trace Macrocell (ETM). This delivers full SWD-based programming, breakpoints, and register inspection using standard tools like Segger J-Link or ST-Link v2, but excludes real-time instruction trace. Debug requires SWDIO, SWCLK, and nRESET pins.
Is hardware flow control supported on UART channels?
No. Hardware flow control (CTS/RTS) is explicitly disabled on CY9AF144LBQN-G-AVE2 per datasheet Section "Hardware Flow control*" (Page 2): "CY9AF141LB, F142LB and F144LB do not support Hardware Flow control." Only software XON/XOFF or application-level buffering is available for UART channel 4.
How is the unique ID implemented and accessed?
The device contains a factory-programmed 41-bit unique identifier stored in dedicated ROM. It is readable via the System Control Block (SCB) register map at address 0xE0042000+ offset, accessible through CMSIS-defined functions like SCB->CPUID or vendor-specific system registers - used for secure boot binding, device authentication, and license enforcement without external EEPROM.
