Product details
Overview
CY9AF144NBPQC-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), and operation up to 40 MHz. It integrates UART/CSIO/I²C interfaces, 24-channel 12-bit ADC (2.0 μs conversion), 8-channel DMA, 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 CY9AF144NBPQC-G-JNE2 datasheet, CY9AF144NBPQC-G-JNE2 pinout, CY9AF144NBPQC-G-JNE2 application, or CY9AF144NBPQC-G-JNE2 equivalent, key selection criteria include dual-bank Flash for seamless firmware updates, 5 V-tolerant I/O on selected pins, hardware watchdog independence from main clock, and SWJ-DP debug support without ETM - critical for safety-aware embedded firmware development.
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 instruction fetch and data access.
The peripheral set includes eight base timers (configurable as PWM/PPG/reload/PWC), two watchdogs (hardware clocked by 100 kHz CR oscillator, active in Stop/Deep Standby modes), and CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32 - offloading integrity checks from CPU during communication or Flash verification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 40 MHz max - enables deterministic interrupt latency & RTOS compatibility |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports background erase/write for live firmware updates |
| SRAM | 32 KB total: 16 KB SRAM0 (I/D bus), 16 KB SRAM1 (system bus) - enables parallel code execution and data buffering |
| ADC | 24-channel 12-bit SAR, 2.0 μs conversion @ 2.7–3.6 V - suitable for fast analog sensing in motor current feedback |
| Low-Power Modes | Six modes including Deep Standby RTC/Stop with RAM retention options - extends battery life in always-on sensor endpoints |
| Debug Interface | Serial Wire JTAG Debug Port (SWJ-DP), no ETM - provides full debug visibility with minimal pin count and power overhead |

Pinout & Package
The CY9AF144NBPQC-G-JNE2 uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are fully defined in Cypress/Infineon Document No. 002-05637 Rev. *D, Section 3 (Pin Assignment) and Section 4 (List of Pin Functions).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| P00–P07, P10–P17, etc. | General-purpose I/O | Up to 83 GPIOs; port relocate function allows flexible peripheral mapping; some pins 5 V tolerant for mixed-voltage interfacing |
| XTAL1 / XTAL2 | Main clock oscillator input/output | Supports 4–48 MHz crystal or external clock source; required for PLL-based high-speed operation |
| OSC32IN / OSC32OUT | Sub-clock oscillator input/output | Drives 32.768 kHz crystal for RTC and low-power wake-up timing |
| SWDIO / SWCLK | SWJ-DP debug interface | Two-pin serial wire debug enables programming and real-time trace without JTAG TAP complexity |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash architecture | Enables Over-The-Air (OTA) firmware update with zero downtime: one bank executes while the other is erased/written |
| Hardware watchdog (CR-clocked) | Remains active in all low-power modes except Deep Standby RTC/Stop - ensures fail-safe recovery even during ultra-low-power sleep |
| HDMI-CEC transceiver | Integrated header block auto-generation, ACK reply, and arbitration loss detection - eliminates external CEC PHY for TV/AV control systems |
| Port relocate function | Allows runtime remapping of UART/CSIO/I²C/SPI peripherals to alternate GPIO sets - simplifies PCB layout and design reuse |
| CRC accelerator (CRC16/CRC32) | Offloads checksum computation from CPU during UART/Flash data validation - reduces firmware cycle count by >90% vs software CRC |

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 dual-bank Flash or HDMI-CEC | Lacks integrated CEC and dual-bank update capability; requires external PHY for AV control | Select when higher CPU speed and larger SRAM outweigh need for OTA-safe Flash and CEC integration |

FAQ
Does CY9AF144NBPQC-G-JNE2 support in-system programming via UART?
No. In-system programming is supported exclusively through the Serial Wire JTAG Debug Port (SWJ-DP). UART is configured for application-level communication only and lacks bootloader functionality for Flash programming. Firmware updates must be performed using SWD-compatible tools such as Infineon's DAPLink-based programmers or third-party CMSIS-DAP adapters.
What is the maximum operating temperature range for this MCU?
The CY9AF144NBPQC-G-JNE2 is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed in Section 12.2 (Recommended Operating Conditions) of Infineon Document 002-05637 Rev. *D. The device maintains full specification compliance across this range, including Flash write/erase endurance and ADC linearity.
Is the RTC battery-backed, and can it retain time during Deep Standby Stop mode?
Yes. The RTC operates from the 32.768 kHz sub-clock and retains timekeeping during Deep Standby Stop mode when the VBAT pin is supplied (typically from a coin cell). Section 12.4.2 specifies sub-clock accuracy of ±20 ppm over –20 °C to +70 °C, and the RTC calendar registers remain powered and functional without main VCC.
How many I²C interfaces does this MCU support, and what are their speed limits?
The CY9AF144NBPQC-G-JNE2 supports up to four I²C channels (ch.0–ch.3), each configurable independently. All channels support Standard-mode (100 kbps) and Fast-mode (400 kbps), as verified in Section 12.4.12 of the datasheet. No Fast-mode Plus (1 Mbps) support is provided.
